Windows 10: no battery is detected

why do I get this when clicking on the battery icon? sometimes my pc will not turn on because it does not detect its own battery.

Battery not detected (Unknown remaining)

Hi,

First of all I suggest you to try with a driver remove and reinstall with Device Manager. To do so:

1. Press WINDOWS + X

2. Click on "Device Manager"

3. Click on "Battery"

4. Right click on the first element on list

5. Click on "Remove"

6. Repeat steps 4 and 5 for the second element on list

7. Click on "Detects Hardware change" (monitor icon)

Then reboot your system and check if the problem still exists.

Please tell me if the solution works.

 

Full charge capacity of battery decreased

Repeat the steps Dave suggest you other three times.

Also you can uninstall and reinstall battery from device manager before each charge. You can do that:

1. Press WINDOWS + X

2. Click on "Device Manager"

3. Click on "Battery"

4. Right click on your battery

5. Click on "Uninstall device"

6. Repeat steps 4 and 5 for each element on battery list

7. Click on "Detects Hardware change" (monitor icon)

 

No battery detected

My Dell E7440 laptop has suddenly started displaying 'No battery detected' in the task bar. I've tried the commonly suggested fix which is to remove battery and hold down power button for 15 seconds but to no avail, even after trying several times. I've
borrowed a second battery (known to be good) from someone with identical laptop and still get 'no battery detected'. As the laptop works OK with the charger disconnected (ie off battery alone) then a battery must be detected or the laptop wouldn't boot! Both
batteries are genuine Dell. I've also tried uninstalling the two entries of 'Microsoft ACPI Compliant Control Method battery' in Device Manager and no change. I'm currently trying a suggestion on YouTube to remove the battery for 3 days then reinsert it but
frankly don't have much hope that it will make any difference. I upgraded to Win 10 several months ago and everything has worked OK with this problem appearing out of the blue a couple of days ago.

Please help!
