  1. Dear All member of Techspot and moderators.

    Recently, My computer is starting change time and dates
    1st day before Normal computer use: work, homework, play, Yehhh! <expression>
    2nd day, when I turn on the computer, it show me today is "March 13, 2014. 3PM"
    Time and Date is wrong. I manually change correct time.
    3rd day, the computer change its time and day again, fix it manually.
    Basically I do 2nd and 3rd repeatly.

    I researched about this problem: I might need change the battery.

    However, I really want to know what is the most important thing to do before I replace the battery. Do I need back up all my saved data in computer ?
    Also, what if I do not replace the battery ? I mean what is the worst situation.

    Your bios setting will get reset, when you change the cmos batterry.

    Take note of the setting, before changing the battery.

    Your data on the harddrive will not be affected, by a battery change.

    I always thought that a weak/dying battery caused reset to factory setting. March 2014 ??

    don't worry you not goon loose anything, the bios will go to factory settings and you will need to just adjust time and date.

    good luck
