Battery stops charging at 80%

[AShSA]

Hello everybody,
After updating to Windows 10 Pro 20H2, the battery is only charging to 80%. I want it back to 100%. Can you please help me finding the right option in Settings or BIOS? (F10 under start for entering BIOS setup does not work). ASh

It may be effective to calibrate the battery.

Thank you, I have solved the question. That was an option in BIOS. I restarted via Settings -> Advanced Startup, and then got access to BIOS, where I modified an option in Power Management.

Hi @AShA,

I'm having the same issue. Would you mind telling what BIOS setting you changed exactly to fix it?

Best,

Ron

Hi Ron,

It was long ago. I do not remember exactly how the option is called, and suppose that it may be different for the different computers.  The idea is that some computers have an option to prolong the battery life by restricting their charge only to 80%. This restriction is called "eco-mode" or whatever the producers have invented. It is either in BIOS or in Control Panel/Windows settings. In my case, it was BIOS.

I hope that this helps... somehow.
