HOW COME MY COMPUTER DOESNT LOSE THE DATE AND TIME, EVEN WHEN ITS UNPLUGGED?
Your timer coffee pot wont remember, how come your computer can? The reason that your computer doesnt forget the date and the time and what it is (its drives, software, settings) is because there is a very small, low voltage battery on the main board that saves these settings. The battery is commonly a silver nickle-sized device that is held on the board by a spring clip. As your computer ages, especially if it remains unplugged for lengthy periods of time, the battery will eventually run down, and must be replaced. If you notice that your Windows clock is losing time, its a good indication that its time to replace the battery, otherwise you may lose some crucial settings and have to rebuild the BIOS.
