    After doing everything, i found my solution. The cmos battery wire is the problem. Glad i tried changing the wire. I was about to solder new bios chip!

    Hi, i have the same problem. Except that mine started when i replaced my old battery with a new one.
    It was working fine for a few weeks before i got this problem.

      This is what I experienced, after replacing the old battery with a new one, this started to happen and the problem was that the CMOS battery had been integrated into the main battery, was there a problem with the main battery?

    I replaced my battery twice. It still occurs although not frequently. Maybe I didn’t replace the battery with exact voltage requirements. Now my question is if I couldn’t find the exact battery and keep using the battery that shows this error message, would it be a problem for my laptop? Thanks.

    I had the same problem and ordered an original battery to replace the old one, however after a few hours of use the blue screen of death started to appaer and my laptop wouldn't stop restarting because the BSD appeared every time. I ran the diagnostics tool and the battery seemed to be good. Then I removed the battery and the BSD still appeared so I just restored windows to a previous state and the BSD was gone, Then I reinstalled the battery and the BSD was back and the worse part is that it completely damaged my SSD NVME. So now I ordered another NVME but I'm not sure if should reintall the battery since I don't want it to damage the ssd again. Any advices?

    We replaced our battery from normal wear and tear and it was working great, even unplugged, but my daughter ran Minecraft on it until the battery was at 3% basically. Now its showing this error and not charging. Do you think we got too cheap of a replacement battery? It is 3rd party I'm pretty sure. (Hubby bought it)
