Good evening, after I updated my drivers with Drive Booster I restarted the computer, the hard drive, SSD is no longer recognized. So I tried to restore the machine to a date when it was working well and it reached 2% the system restoration did not finish properly, I left the machine almost 2 hours; it got stuck at 2% and when I forced the PC to shut down, I notice that the machine cannot boot, black screen. I think the BIOS is corrupted. I did Ctrl+Escape by plugging in the charger but I can't show the recovery, it seems I had disabled it. Anyway, how to reset the BIOS without reprogramming because I ordered the USB key and the kit needed to reprogram the BIOS but for now I’d like to know if there is a solution to reset the BIOS on the PC. I unplugged the battery and the CMOS battery, left the computer unused for several hours and then reconnected everything, but when I turn on the PC it remains black.

    Hello!
    It's me, Bobot, the AI ready to surprise you!
    To reset the BIOS on your Dell G5 15 5587, you can try the following procedure:

    1. Turn off your computer and unplug the power cord.
    2. Open the rear panel of your computer near the battery.
    3. Locate the CMOS battery (a small silver battery) and carefully disconnect it.
    4. Stay without the CMOS battery for about 10-15 minutes to allow the BIOS to reset.
    5. Reconnect the CMOS battery and the power cord.
    6. Turn on your computer and try to enter the BIOS by pressing the appropriate key (usually F2 or DEL) at startup.

    Note, however, that if your BIOS is truly corrupted, this method may not work and you may need to wait for your USB drive and the reprogramming kit. If you have doubts, feel free to consult a professional.

    Hello,

    Sorry for the intrusion..!!

    Detaching the battery for a good quarter of an hour will not recharge it... The lithium battery in question is not rechargeable.. its lifespan is highly variable, between 5 and 10 years... Its voltage is around 3 volts, 2.8V is already too low...

    Without certainty and without reliable measurement, the prudent thing is to replace this battery with a truly new one...

      Hello Jeannets,

      To be more pragmatic about CMOS 2032 batteries, lifespan and voltages—I have tested many on old PCs to restore; correction, it's ten years minimum and 0.2 volts lower, which does not in any way affect the PC's operation.

      For information, even AA batteries work with devices at voltages much lower than those specified; my rechargeable batteries are 1.2V instead of 1.5V by default, they are designed to operate like that as a comparison.

    It used to be true on old PCs... with 40-pin C-MOS, and also Ni-MH batteries that were recharged during the operation hours of the motherboard...

    Now the chips are much more compact, internal buses are serialized and frequencies are significantly higher... it takes power...

    In short..! that doesn't detract from what you say, I don't doubt it... there are so many strange things around MOS, among others... this BIOS didn't necessarily need an update..? risking a version error..??

    hello

    do you have access to the BIOS via Del or F2?
