    Probably caused by a flat CMOS battery.

    I just noticed that your computer is a laptop. In that case we will need to know the brand and model number (you should find the model number on a sticker on the underside of the laptop).

    Should be the battery problem. Bios battery is used to retain the settings of the Date and time RTC Real Time Clock. it always have to have power to it. that is why the battery is there to keep the time and date right.
