Information from another case (not my case), similar to mine:
My laptop shows it’s charged 100%; however, when I unplug the charging cable, my laptop instantly turns off, no shutdown screen it just goes black. It’s almost as if the battery is not connected, but clearly if the laptop shows it’s 100% charged, it can detect it.

Troubleshooting steps:

Make sure the power cord and adapter is connected to the system and wall outlet.

• Press and hold the power button until the computer turns off completely.

• Turn on the computer.

• Immediately press the F2 key repeatedly, about once every second, until the UEFI Hardware Diagnostics screen is displayed.

• In the UEFI Main menu, select Component Tests.

• In the Component Tests menu, select Power.

• In the Power menu, select the battery tests

Results:

The test was not completed as it jumped from 1% to finished in 5s. I ran the test again and the same results came up.

Outcome (according to the other case):

The fact that the test results weren't accurate and it finished within seconds, confirms a hardware malfunction and I suggest you talk to HP support and discuss your options.

Troubleshooting the notebook battery

If you have a second battery for your computer, replace the original battery with the second battery and perform the troubleshooting steps again.

• If the computer powers on with the second battery and the battery charges correctly, contact HP Customer Support for battery replacement. See Purchasing a Replacement Battery.
• If the problem remains with the new battery, you might need to replace the system board. Contact HP Customer Support for further assistance.

My problem seems to be the motherboard. In other words, I have a high risk of losing my data, a high risk of reinstalling the Windows OS, and a high probably of ending up reinstalling some drivers, is that correct? Is there an expert in this forum who can provide their opinion?
