Dell Vostro 3500 CMOS Battery Replacement

はじめに

Note that disconnecting the so-called CMOS battery does not reset the BIOS settings or clear a BIOS password. In fact its only purpose is to maintain the real time clock when no other power source is available.

The CMOS battery should last for around 10 years. If the computer forgets the date and time when you remove both the mains adapter and the main battery then you need to replace the CMOS battery.

Locate the CMOS battery
Gently disengage its connector.
Do not disengage the connector by pulling the leads as you may tear them out of the connector. Instead, pull on the connector itself, ideally with a pair of tweezers, rocking it back and forth alternately in the directions of the red and black leads.
