## Description

Do you get wrong date and error messages when your laptop is powered? Can't load correctly? (If the date setting is unmeaning, Windows XP will not be able to load correctly. May happen when CMOS battery voltage is low). Then it's time to replace the CMOS RTC coin battery. Every computer is equipped with a small coin cell battery that powers the BIOS chip, which can effectively keep the date and other internal settings. If you don't have these cmos batteries or cmos batteries, these internal settings will not work. CMOS RTC batteries need to be replaced every few years (usually 3-4 years).
