Most Windows notebook computers power management settings will default to putting the computer to sleep with the lid closed, regardless of any external displays, keyboard, or mouse connected to the computer. If this is happening but you would prefer the system to remain active with the lid closed utilizing the external display or displays, these settings can be changed by performing the following:

For Windows 10:

1. Start by right-clicking on the Start button and select Power Options from the menu.
2. From the right side of the Power Options settings page, select the blue link for Additional power settings

   

3. From the choices present on the left-hand side of the Power Options window, please click on Choose what closing the lid does
4. Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing

   

5. Click the Save Changes button and restart the system (making sure that the laptop’s power adapter is also connected) and test the behavior again.

For Windows 11:

1. Start by right-clicking on the Start button and select Power Options from the menu.

   

2. In the upper left corner of the settings window, in the search box, type "lid" then select Change what closing the lid does from the search results

   

3. Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing

   

4. Click the Save Changes button to apply the new settings.

Closing the lid should no longer put the computer into sleep mode when an external display and power source is connected, instead one of the external displays should now become the Primary display with the desktop icons instead of the laptop's built-in display.

The lid may still need to be opened to perform the following tasks:

• To power on the computer from a fully powered off state
• To log into the computer if logged out or if the computer is restarted with the lid closed
• To wake the computer from a deep sleep state ( hibernation, or Windows hybrid sleep states )

When the TBT3-UDV is used with certain Windows 10 or Windows 11 systems, there is a possibility that two of the USB 3.0 ports located on the back of the dock (closest to the Ethernet port) may not be recognized properly by the operating system. This issue is not present when the TBT3-UDV if used with an Apple Mac system running macOS.

Should this occur, while the dock is connected to the host PC (this is important) please download and install an updated Asmedia USB 3.0 Host controller driver from here and reboot the system and test the behavior again. 

If that does not resolve the issue, please reach out to us directly via support@plugable.com and we will be happy to help.

Not all Thunderbolt 3 systems support charging via their Thunderbolt 3 port. But for systems that do support charging via Thunderbolt 3, yes, the dock can provide up to 60W of power to charge the host system. 

In order for the system to charge, the system must be connected to the Thunderbolt 3 port on the back of the dock with the small ‘Computer’ icon above it. This port can provide up to 60W of power to charge the host system.

If your system is able to be charged via Thunderbolt 3 and is not charging, please ensure you have the system connected to the proper port within the dock.

The Thunderbolt 3 port labeled with the ‘Computer’ icon can provide up to 60W of power. The other Thunderbolt 3 port can provide up to 15W of power. 

The solid green light indicates that the dock is receiving power from its power adapter. The solid blue light indicates an active connection to a Thunderbolt 3 host.

Only the single front-mounted USB 3.0 port of the TBT3-UDV dock supports BC 1.2 charging. 

For example, a mobile phone that supports BC 1.2 charging will charge when connected to the front USB 3.0 port of the dock, even if the dock is not connected to a laptop. 

The remaining four USB 3.0 ports on the back of the dock will only provide standard USB power to USB devices (up to 900mA) when the dock is connected to a host laptop. They do not provide any special charging capabilities, and they will not provide power if the dock is not connected to a host laptop.

The TBT3-UDV is not supported within the Apple Boot Camp environment. 

This typically occurs because the cable being used to connect the dock to the system is not a Thunderbolt 3 cable, but rather a USB-C cable (the white cable included with MacBook Pro laptops for charging is a USB-C cable, not Thunderbolt 3). 

Please use only the Thunderbolt 3 cable we include in the box with the dock to connect it to your system. For additional information about this issue, please see this demonstration video -> https://youtu.be/YJKKOjFc6zE

Typically this is caused by the system not correctly detecting the Ethernet device within the dock. In most cases, completely resetting the dock and ‘cold booting’ the system by following this procedure can help:

1. Disconnect the dock’s Thunderbolt 3 cable from both the dock and the system, and disconnect the dock’s power cable so it turns off completely.
2. Shutdown the Mac system completely (do NOT just restart).
3. Power on the Mac system and login.
4. Reconnect the power cable to the dock, and then reconnect the Thunderbolt 3 cable to both the dock and the system.
5. Test the previously non-working Ethernet port.

The symptoms described above most often indicate that the Ethernet port device is being detected, however macOS is not automatically creating a new network service for the device. In most cases manually adding the service by following this procedure can help:

1. Click on ‘System Preferences’ (gear icon in the macOS 'Dock').
2. Click on the ‘Network’ Application (globe icon).
3. In the bottom left-hand corner of the ‘Network’ application, click on the “+” (plus) sign to add a new service.
4. Click on the ‘Interface’ drop down and select ‘Thunderbolt Ethernet Slot 1’.
5. Leave the ‘Service Name’ populated with the default name and then click the ‘Create’ button.
6. Click the ‘Apply’ button in the lower right-hand corner of the application to apply the changes.
7. Wait a few moments to see if the Ethernet adapter in the dock starts working.

In most cases, this type of behavior is caused by the dock to not being properly Authenticated/Approved as a Thunderbolt 3 device (Apple systems do this automatically, and as such do not apply here). 

If not approved, the USB ports, Ethernet port and audio port within the dock will not work (video outputs always work regardless of Approval status). In most cases, this is caused by the Intel Thunderbolt software that handles the authentication process not working properly. 

Should this occur, the best practice is to remove and reinstall the Intel Thunderbolt software to ensure it is in a good state and reset the dock, the procedure for doing so is below:

1. Disconnect the Plugable Thunderbolt 3 dock from the system and remove its power cable so it turns off completely. Please keep it disconnected until prompted.
2. Uninstall the Intel ‘Thunderbolt Software’ present on your system via the Control Panel -> Programs and Features.
3. Restart the system, even if not prompted.
4. Download and install the latest version of the Intel Thunderbolt Software published by your system manufacturer.
5. Restart the system once again, even if not prompted.
6. Reconnect the power cable to the Plugable Thunderbolt 3 dock, and then reconnect the Thunderbolt 3 cable from the dock to your system.
7. You should be prompted to authenticate/approve the dock by the Intel Thunderbolt Software. Please approve the device using the ‘Always Connect’ option. * There is a chance the approval prompt will not pop-up automatically. If that is the case please just proceed with the next step for now. *
8. Please test any non-functioning ports in the dock again.

In rarer cases, this can be caused by an incorrect setting within the Thunderbolt options within the system’s BIOS. System manufacturers typically enable ‘User Authorization’ or ‘No security’ Thunderbolt options in the BIOS by default. As their names imply, the respective options indicate that a Thunderbolt device must be authorized in order to work, or no authorization is needed. If other options such as ‘DisplayPort Only’ (Dell terminology) or ‘DisplayPort and USB only’ (Lenovo terminology) are selected, no Thunderbolt 3 devices will work. These options turn the port into a USB-C only port. Please ensure that the BIOS options are set as intended using your system manual as a guide.

With macOS, Windows 11, and Windows 10 the operating system will download and install the necessary drivers when the dock is connected.

When using Windows 7 64-bit (32-bit systems are not supported), you will need to install a separate Intel Network Adapter driver and a driver for the Asmedia USB 3.0 Host Controller.

The TBT3-UDV dock includes both a Fresco FL1100EX USB 3.0 Host Controller and an Asmedia ASM1042A USB 3.0 Host Controller. In terms of routing, when the dock is in the vertical position the two USB 3.0 ports on the top of the back of the dock and the single USB port on the front of the dock are connected to the Fresco controller. The lower two USB 3.0 ports (closest to the dock's Ethernet port) are connected to the Asmedia controller.

The TBT3-UDV has a CMedia CM6533 Audio chipset. For detailed specifications, please see the Cmedia website here

The Active DisplayPort to HDMI active adapter included in the box with the docking station is based on the Parade PS176 chip. This chip does not support bit-streaming/pass-through of Dolby or DTS. However, it does support up to 8 channel audio via LPCM output.

Please check to ensure that the default audio playback device within your operating system is set to ‘Plugable TBT3-UDV Dock Audio’

Please see this knowledge base article for detailed instructions --> Link

The TRRS combination audio input and output jack located on the front of the TBT3-UDV docking station is not compatible with a standard analog microphone.

No, Wake-on-LAN is not supported.

Using the dock in combination with a physical KVM switch is not supported, as we have found that their performance varies widely and cannot be guaranteed.

The ability to connect a second display to the Thunderbolt 3 docking station's second (also known as 'downstream') Thunderbolt 3 port is ultimately determined by the design internal decisions made by the host system's manufacturer. 

To expand further, system manufacturers have discretion when designing their Thunderbolt 3 systems in regard to how may displays are supported via a single Thunderbolt 3 connection to the host.   Some manufacturer's support two displays via a single Thunderbolt 3 connection, while others may only support one display via a single Thunderbolt 3 connection.  We have produced a video that provides for more information on this topic for those who are curious here --> Link

Unfortunately, system manufacturer's specifications often do not include this level of detail.  The best practice is to check directly with your system manufacturer to determine the host system's capabilities.  

To convert the dock’s built-in DisplayPort output to HDMI: Please use the included Active DisplayPort to HDMI adapter (maximum resolution of 4K@60Hz refresh). 

To convert the DisplayPort output to DVI or VGA, please purchase separately an Active DisplayPort to DVI or VGA adapter. The adapter MUST be of the 'active' type, 'passive' adapters will not work.

For systems which support a second display output through the docking station via its second (also known as 'downstream') Thunderbolt 3 port, please make a separate purchase of one of the following:

USB-C to DisplayPort (6′ cable): Plugable USBC-DP Alt Mode Adapter Cable

USB-C to HDMI (6′ cable): Plugable USBC-HDMI-CABLE Alt Mode Adapter Cable

USB-C to VGA (6′ cable): Plugable USBC-VGA-CABLE Alt Mode Adapter Cable

or

USB-C to HDMI (dongle): Plugable USBC-HDMI Adapter Dongle

USB-C to DVI (dongle): Plugable USBC-DVI Alt Mode Adapter Dongle

USB-C to VGA (dongle): Plugable USBC-VGA Alt Mode Adapter Dongle

No, Wake-on-LAN is not supported.

If your Windows laptop will not boot properly when a docking station is connected to the laptop, most often the cause is an external device connected to the docking station (for example an external USB storage drive) as opposed to the dock itself. 

If you are affected by this condition, please follow these steps in order to isolate the behavior further:

1. Disconnect all USB devices from the docking station and put them aside for the moment.
2. Disconnect any displays connected to the dock's video outputs.
3. Disconnect any audio devices connected to the dock's audio ports (if present).
4. Disconnect the Ethernet network cable from the dock's Ethernet port (if present).
5. The only remaining connections should be the dock's power adapter cable and the USB cable used to connect it to the laptop. No other external devices should be connected to the dock.
6. While in this state, reboot the laptop to test the behavior.
7. Assuming the laptop boots as expected, please reconnect each device back to the dock one at a time and reboot after each one to test the behavior again. Please reconnect the displays first, then the audio devices, then the Ethernet cable. Please reconnect any USB devices to the dock last, again rebooting after each one is added to test the behavior.

In our experience helping others, the most common cause of this behavior is an external USB storage drive connected to one of the dock's USB ports.  In some cases, a laptop may try to boot from an external storage drive by mistake as opposed to the laptop's built-in storage drive.  Since most external USB storage drives are not 'bootable', this can interrupt the boot process. 

If this behavior occurs, the most common way to mitigate the behavior is to access the laptop's System BIOS (also known as UEFI firmware) to change the 'boot order' settings to ensure that the laptop's internal storage drive is the first boot option.  Doing so helps ensure that the laptop will not try to boot from an external USB storage device. 

Every laptop system is different, so the best resource for accessing the System BIOS and changing the settings is the manual for the laptop provided by the laptop manufacturer.

Most Plugable docks do not officially support monitors over 60Hz including 120Hz or 144Hz refresh rate unless otherwise specified on the Plugable product page or listing. 

DisplayLink USB Graphics technology and Silicon Motion based docking stations and graphics adapters, like our USB 3.0 dual display and USB Type-C triple display docking stations, are limited to 60Hz fresh rate by the USB graphics controller hardware.

USB Type-C DisplayPort Alternate Mode docking station and ports on our USB Type-C Triple Display Docking Stations can support higher refresh rates, but may be limited by the computer's capability and available bandwidth to the docking station.  Additionally, when paired with DisplayLink or Silicon Motion USB graphics, having displays at different refresh rates may reduce overall system performance.  Due to this we normally recommend limiting all connected displays to 60Hz refresh rate when using DisplayLink and Silicon Motion graphics technology with directly connected, or USB Type-C DisplayPort Alternate Mode controlled displays.

Monitors with refresh rates higher then 60Hz may be connected to a docking station operating at up to 60Hz, or connected directly on the computer's HDMI or DisplayPort to ensure the display is powered by the system's native GPU.

Unfortunately Plugable products do not support the Apple SuperDrive.

The Apple SuperDrive has stringent power requirements that can only be met by directly connecting the SuperDrive to your host laptop. As a result at this time Apple recommends only using their USB-C adapter cables. You can find more information on that here -→ How to connect the Apple USB SuperDrive

Synopsis – If your Thunderbolt 3 driver or utility version types are mismatched within a Windows host system, you may receive an error message stating, “Application Cannot run – This Thunderbolt application is not in use anymore and can be safely uninstalled” when attempting to run the Intel Thunderbolt Software management utility or the Intel Thunderbolt Control Center utility. This prevents proper management of Thunderbolt devices on the host system. (This problem does not occur on Apple Mac systems.)

Before proceeding with this or any other procedure that makes changes to your system, please ensure you have a full system backup of any and all important data and create a fresh System Restore Point as a precaution. Plugable will not be able to help restore any data or return a system to a working state should things not work as expected. If you do not wish to take this risk, please do not follow this procedure

You will have to be logged on to the system as a User with ‘Administrator’ permissions in order to perform these steps

1. Disconnect any Thunderbolt 3 devices from the host system (this is done to prevent Windows Update from automatically loading any Thunderbolt drivers).
2. Right-click on the Windows Start button and select ‘Device Manager’.
3. Click on ‘View’ from the application menu bar, and click the option ‘Show hidden devices’ (this is necessary because the Thunderbolt controller will not be active if no Thunderbolt devices are connected).
4. Expand the ‘System Devices’ category. Scroll down until you find the entry for the ‘Thunderbolt Controller’.
5. Right-click on the ‘Thunderbolt Controller’ entry and select ‘Uninstall device’ from the context menu that appears.
6. From the ‘Uninstall Device’ window that appears, click to place a check mark within the ‘Delete the driver software for this device’ option.
7. Click the ‘Uninstall’ button.
8. Close Device Manager.
9. Click the search button on the taskbar (looks like a ‘O’) and search for the letters ‘cmd’.
10. Right-click on the ‘Command Prompt’ search result and select ‘Run as Administrator’ from the context menu. If prompted, enter your Administrator password.
11. From the Administrative Command Prompt window, enter ‘sc delete nhi’ (without the quotes) and press enter. You should receive a ‘SUCCESS’ indicator. ** Be very careful to type this command correctly ** 

This command deletes the ‘nhi’ Windows service presently installed on the system.

Overview and Drivers

In general, Plugable Thunderbolt 3 Docking Stations and Thunderbolt 3 Dual Display Adapters do not require the installation of any drivers when used with macOS or Windows. When connecting a Thunderbolt 3 device, the host operating system should install all the necessary drivers automatically.

However, there are certain instances with Windows systems where additional driver installation may be necessary when using our Thunderbolt 3 docking stations (these are NOT required on macOS systems):

TBT3-UDV Docking Station:

• Windows 10 – In general, no driver installations are required when using Windows 10. After initial connection if all functions of the dock are working as expected, then no additional action is required. However, when the TBT3-UDV is used with certain eighth generation Intel processor-based Windows 10 systems an updated USB 3.0 driver may need to be installed to ensure the best performance of USB peripherals attached to the TBT3-UDV. We recommend installing the updated Asmedia USB 3.0 drivers here. For additional details, please see our TBT3-UDV product page.
• Windows 7 – When using Windows 7 64-bit (32-bit systems are not supported), you will need to install a separate Intel Network Adapter driver and a driver for the Asmedia USB 3.0 Host Controller.

TBT3-UD1-83 / TBT3-UD1-85 Docking Stations:

• Windows 7 – When using Windows 7 64-bit (32-bit systems are not supported), you will need to install a separate Fresco USB 3.0 Host Controller driver and an Intel Network Adapter driver.

General Thunderbolt 3 Information

Before purchasing or using a new Thunderbolt™ 3 docking station or video adapter for use with your personal computer running Windows, you will want to make sure that your computer can support it and be aware of differences from basic USB devices:

Note: The following does not apply to Apple Thunderbolt 3 systems.

• Many early Thunderbolt 3 PCs require firmware and software updates before all adapters and docks will work.
• Dual display support is optional for Thunderbolt 3 PCs. How many displays are supported over Thunderbolt 3 depends on how the USB-C port has been wired on the system motherboard (up to a max of two), and is not changeable in software or by the Thunderbolt 3 graphics device.
• Support for PC charging (USB Power Delivery) on Thunderbolt 3 systems is optional. Many Thunderbolt 3-enabled PCs do not accept a charge over USB-C, and some PCs only will charge with their own branded power adapters.
• Unlike USB devices, Thunderbolt 3 devices must be manually authenticated (approved) for use by the user before the system will recognize them.

Additional detail

• Host computers equipped with Thunderbolt 3 have the ability to install various updates including NVM (Thunderbolt 3 related Non-volatile memory) and PD (Power Delivery) firmware, UEFI BIOS, supplemental Thunderbolt 3 software utilities (for authentication) and various drivers to resolve potential issues and increase compatibility with new Thunderbolt 3 products as they are released.
• System manufacturers have substantial discretion in how they implement various technical elements and features. As a result, compatibility information is complex. As a result many currently available Thunderbolt 3 systems are not fully compatible with our Thunderbolt 3 dual graphics adapters (we do our best to maintain compatibility tables of the individual product pages). Some systems may only be equipped with a single DisplayPort (DP) Alternate Mode (Alt Mode) line to the Thunderbolt 3 port which limits the port to a single display output. Due to this limitation some systems won’t be able to take advantage of our dual port Thunderbolt 3 graphics adapters regardless of firmware/software updates. This is a physical hardware limitation.
• Many system manufacturers ship systems with older firmware and may or may not have updated versions available for download at this time. The latest Thunderbolt 3 firmware for a specific system cannot be downloaded from Intel directly, as it first it has to be customized by the original system manufacturer. Intel has a Thunderbolt updates page with some update information, but as of this writing the list if fairly small. Currently our TBT3-HDMI2X-83 and TBT3-DP2X-83 adapters require the host system to have a Thunderbolt 3 firmware update with NVM version 14 or higher in order to work properly. The latest UEFI BIOS update from your system manufacturer must be installed before updating the NVM firmware.

Operating System Compatibility

Thunderbolt 3 technology is supported by any operating system which has driver support for Thunderbolt 3. Currently, Plugable supports Windows 10, 8.1, and 7 (64-bit only) and macOS 10.13 or later. Although support for Thunderbolt 3 devices under Linux is steadily evolving, Plugable does not support Thunderbolt 3 devices within a Linux environment at this time.

General Thunderbolt 3 FAQ

Q: Can a Thunderbolt 3 dock or adapter work in any system with any USB-C (USB Type C) port?
A: It depends.

• Early Thunderbolt 3 docks and adapters will only work with Thunderbolt 3 USB-C computers and ports and connecting to a USB-C port without Thunderbolt 3 capability will not work. Note that computers and docks may have a mix of Thunderbolt 3 and other USB-C ports that look very similar. Look for the Thunderbolt icon on both sides of the connection to ensure compatibility:

• Current Titan Ridge based docking stations like our TBT3-UDC1 and TBT3-UDZ are backwards compatible with USB-C systems in most cases (with limitations).

Q: How can I identify the NVM version on my system?
A: See “Identifying the NVM” section below.

Q: What if a newer compatible NVM is not available from my system manufacturer?
A: Unfortunately the only option is to contact your system manufacturer and ask when a newer version will be available, and to let them know that until it is, certain accessories you are looking to use will not work.

Q: How can I identify if my system has the necessary two DisplayPort lines to provide dual display output through the Thunderbolt 3 port?
A: Unfortunately in many cases this information is very hard to discern based on the manufacturers published specifications. If your system is not among those listed in our compatibility table above, please contact your system manufacturer for confirmation of how many DisplayPort lines are routed to your Thunderbolt 3 port.

Q: I connected my Thunderbolt 3 dual display adapter and my monitor configuration changed by itself.
A: This may occur and is considered normal. You can change the main display back to your desired screen through the “Display settings” control panel.

Q: I connected my Thunderbolt 3 dual display adapter and am only getting a single output.
A:  Depending on what Thunderbolt 3 equipped system you have, it may only support a single output because of the DP Alt Mode line configuration. See above “Known Host NVM Versions & DP Lines” to find out if your system has one or two lines.

Q: I connected my Thunderbolt 3 dual display adapter for the first time and my system crashed (hard lock).
A: Check to see if your system is running the latest Thunderbolt 3 software, NVM, UEFI BIOS, and all other updates from your system manufacturer. If everything is updated, unplug the adapter, reboot the system, and then reconnect.

Q: I connected my Thunderbolt 3 dual display adapter and am not getting any output to either display.
A: If your system has hybrid graphics (combination of built-in Intel GPU and AMD or NVIDIA discreet graphics) make sure the Intel GPU is set to be the primary GPU in the UEFI BIOS.

We are often asked if it is okay to leave a notebook computer connected to one of our USB-C docking stations with Power Delivery for extended periods of time.  The short answer is yes, it is no different from leaving the laptop connected to the manufacturer's original USB-C power supply for the same time.  The long answer is yes for modern laptops, and maybe for older (1990s-early 2000s laptops) and involves going into the different battery technologies used in consumer electronics devices.

Another common question is if it is possible to use the docking station but to disable powering and charging the computer.  When a modern notebook computer runs on battery power it will often set the system to a reduced power state which may impact performance, or connected devices and we recommend always powering the computer when using a desktop docking station.  For all of our docking stations that provide power to the host computer this will not affect the lifespan of the computer's battery.

Modern Laptop Batteries: Lithium-Ion

Lithium-ion (li-ion) batteries are found in a wide range of consumer electronics from notebook computers and cell phones, to electric cars, power tools, and wearable electronics like wireless earbuds.  Li-ion offers fast charging, high-current discharging, fairly long service live compared to other rechargeable battery technologies and are relatively inexpensive.

The life-span of a rechargeable battery depends on many factors including age, temperature history, charging patterns, the chemical composition of the specific battery, and usage.  For example batteries stored at 100% charge will degrade faster than batteries stored at 50% charge, this is why most consumer electronics devices arrive from the manufacturer with between 25% to 75% charge.

Lithium-ion batteries are consumable components, however in most modern computers, cell phones, and tablets these are not user serviceable components.  To help maintain the battery all modern computers and most consumer electronics will include battery charge and protection circuits.  These can be fairly simple, charging up the battery at preset rates depending on the charge level to help maintain the battery life, or complex software controlled charging that monitors battery temperature, voltage and current draw to maintain the fastest charging while maintaining the battery longevity.

Modern notebook computers can be left connected to the original power cable or a docking station with charging capability for extended periods, and do not benefit from regular discharge/recharge cycles.  Our docking stations with charging capability rely on USB Type-C Power Delivery to power and charge compatible computers.  USB Type-C Power Delivery is a negotiated charging protocol between the host computer and the docking station or USB Type-C power supply, this allows the computer to draw only the power it requires, and even select the best voltage level for powering the computer.  In combination with a computer's built-in battery charging controller the computer is capable of maintaining the battery's optimal state even when left connected to a power source for an extended period of time.

Legacy Laptop Batteries: NiCad and NiMH

Older laptops, from the 1990s and some early 2000s, as well as some consumer electronics, and most rechargeable AA or AAA battery replacements use Nickel-Cadmium (NiCad) or Nickel-Metal Hydride (NiMH) batteries.  These batteries are slower to charge and discharge than li-ion batteries, and require very simple charge controllers, and in some cases can even be trickle-charged ( very low-current continuous charging ) if desired.

These batteries generally don't have smart charging controllers and to prolong the life of the battery required "training" or fully discharging and recharging the battery every so often.  Many laptop manufacturers recommended fully charging and discharging a new laptop 2-3 times to train the battery, this is not necessary with modern laptops.

Conclusion

Modern notebook batteries are managed by the computer's built-in battery charging circuit, and require little to no user intervention to maintain optimal battery health.  It does not harm the battery to leave the computer connected to an external power supply, so long as the computer is being used regularly.  If the computer is to be stored for a prolonged period then discharging the battery to between 50-75% can help to maintain the battery life.

Batteries are consumable components and degrade over time, however modern notebook computers can extend the battery life generally to meet or exceed the life of the computer's other electronic components.
