## Description

Always got wrong date and error message when you turn on your laptop? Even the Windows XP can't be loaded correctly? (Windows XP can't be loaded correctly when the Date setting is no sense, this could happen when the CMOS battery voltage is low). Then it is time to change your CMOS RTC coin battery! Every computer has a small coin cell battery to power the BIOS chip to keep the date, and other internal settings effective. Without these cmos batteries or a dead cmos battery these internal setting will not function. CMOS RTC battery should be replaced every few years (typically 3-4 yrs).
