HP Battery or hardware problems

Question

The battery power indicator on my Hp notebook was stuck at 100% and all the time shows same value even without battery. Also remaining time is incorrect! Due of this the laptop turns off 2-3 times, but when restarted the battery continues to work for 90 minutes.
Several times when I try to update the Microsoft ACPI-Compliant Control Method Battery driver, the display is locking and the laptop is turned off itself.
I wonder, how can Windows system show 100% in the parameters of batteries when there is no battery in a laptop?
I could not find answer on this thread!

Does anyone know what could be the reason for such a problem in the battery or hardware?

Thanks.

Answer 1

I'd ask HP or possibly in their forums about problems with the hardware.

Please download and install each:

HP UEFI hardware diagnostics version 8.5: https://ftp.hp.com/pub/softpaq/sp138001-138500/sp138354.exe

HP Hardware diagnostics Windows version 1.8: https://ftp.hp.com/pub/softpaq/sp135501-136000/sp135762.exe

Plan to run the HP UEFI hardware diagnostics overnight: Power on the computer > repetitively click F2 or F10 > open the HP UEFI hardware diagnostics > select extensive > loop until error > the next day if it has made two or more loops > click esc > take pictures or the tests performed with results > post images or share links into this thread

Click component tests to view the available tests > later compare to the component tests using HP Hardware diagnostics Windows.

After posting the images or share links for the HP UEFI hardware diagnostics launch the HP diagnostics Windows.
Run the component tests as needed > post images or share links into this thread
