Battery is shown as 0%

[ghostslayer989]

OS: Linux Mint 19.1

My laptop's battery percentage seems to have dropped? Windows 10 said it was plugged in not charging.

I installed an SSD later on and on Linux Mint it still dropped. It finally reached zero and stayed at zero. But when unplugged it doesn't die? I have tried 2 chargers to no avail. It seems the sensor for the battery percentage died out? Please help/

Linux is not going to have the HP diagnostics available to run on the battery to get an assessment of the hardware. How old is the battery? You can download a bootable UEFI diagnostic thumb drive and that may be what we need to have you do in order to get a report on the battery's health. We need the full model number.

...I only have linux. And UEFI only allows Hard Drive or a Memory Test.

Exactly. Only the hard drive and memory test are embedded in the BIOS chip so that is all you will see when you tap f2 booting up...all other UEFI functions are stored in a Windows installation on a system partition. You do not have that. So you have to use a bootable thumb drive with the full UEFI diagnostics on it. See pages 24 and 25 here:

You will have to create the thumb drive on a Windows machine. I did ask how old the battery is. Do you know?

Idk the age and I don't have a windows machine

The most common reason for battery problems is a battery that needs to be replaced.

I said it doesn't die when unplugged in the original message. It stays alive for aslong as the OS doesn't shut down due to low power (Can be disabled in settings) But I will never be able to know it's TRUE percentage.

Ok so after 6 Months of having this issue it now shows 91% (Fully Charged). I did a very recent kernel update but it showed 0% on windows before linux so that's not it. (It drops the percentage at a normal rate and goes back up when  plugged in so charger isn't faulty)
