Windows laptop turns off when unplugged

If you are facing the problem where your Windows 10 laptop turns off when unplugged, even with a new Battery, then this post could be helpful for you. The most obvious reason for a laptop shutting down immediately after unplugging the power cord is that the battery might have gone bad. However, that isn’t always the case, especially with newer laptops.

It should be noted that the battery usually degrades over some time and the change is noticeable. If the battery became dysfunctional instantly, it is possible that the issue is with the settings of the system, connections, or laptop hardware, but not the battery itself.

  1. Change Advanced Power settings
  2. Run the Power Troubleshooter
  3. Hard/Power reset your laptop
  4. Update the battery drivers
  5. Update the BIOS.

A good test could be to plug the battery of a similar laptop and check if it works with the other device. In case you are facing this issue, please proceed with the following troubleshooting.

1] Change Advanced power settings

At times, when a system is forced to shut down without following the appropriate process (e.g. pulling out the battery), the laptops Power Management settings get altered. We could fix it as follows:

Press Win + R to open the Run window and type the command powercfg.cpl. Press Enter to open the Power Options window.

Click on Change plan settings for the current plan in use.

On the next window, select Change advanced power settings.

In the next window, expand Processor power management > Maximum processor state.

Change the value for On battery mode to 25%.

After this, enable Adaptive brightness.

Shut down the system and try booting it with the power cord unplugged.

2] Run the Power Troubleshooter

The Power Troubleshooter checks for problems with the power settings of the laptop and resolves them if possible.

To run the Power troubleshooter, click on Start and go to Settings > Updates and Security > Troubleshoot. Select and run the Power Troubleshooter from the list.

Restart the system and check if it solves your problem.

3] Hard/Power reset your laptop

A hard reset of a laptop resets the hardware settings but does not affect any personal data. The procedure for a hard/power reset is as follows:

  1. Switch off the power of the Windows device.
  2. Disconnect the charger and remove the battery from the device.
  3. Press and hold the power button for a minimum of 30 seconds. This will discharge capacitors of the motherboard and reset memory chips that were constantly active.
  4. Reinsert the battery, plug in and charge the device.

Check if it works, else proceed to the next solution.

4] Update the battery drivers

The issue in discussion could be caused if the battery drivers are outdated. In such a case, we could update the battery drivers as follows:

Press Win + R to open the Run window and type the command devmgmt.msc. Press Enter to open the Device Manager window.

Expand the list of battery drivers. Right-click and update the one for your battery.

Restart the system once done.

5] Update the BIOS

Sometimes, the problem could be that the BIOS is obsolete. This affects the chipset and subsequently, the communication between the battery and laptop. Thus, you could update the BIOS as follows:

  1. Press Win key + R key to get to the Run window.
  2. Type msinfo32 and hit ‘Enter’.
  3. Check the BIOS version/Date info on the right pane of the System Information window. Note down the version.
  4. Check if this is indeed the latest available version for your model. If not, update the BIOS following the instructions on the support website.

Hope something here helps you.
