    Check the terminals running from the battery holder to the motherboard. Also, is there an oscillator for the time/date timekeeping? If so, check those terminals and resolder the CMOS battery's terminals and resolder the oscillator's terminals and report back on the status.
    Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

    My computer doubles as a space heater.

    Asus Q550LF (Old main laptop, 2014-2022) - Decommissioned and stripped due to a myriad of problems, the main battery bloating being the final nail in the coffin.
