Why does my Acer Laptop have random loss of BIOS settings?

If your Acer Laptop is randomly losing BIOS settings, and it is more than a year old, replace the CMOS battery. Run a complete virus scan using up-to-date software. If the computer is experiencing HDD or ODD BIOS information loss, disconnect and reconnect the power and data cables between devices. If HDD information is missing from the BIOS, the drive may be defective and should be replaced. As a last resort, replace the motherboard.
