Direct replacement for Satellite P100-473

This CMOS battery restores BIOS clock and settings on the Toshiba Satellite P100-473 laptop. It is a direct-fit lithium cell for the motherboard RTC circuit, not a main power pack. Installers who need to fix a dead system clock or lost CMOS data will use this part.

Lithium coin-cell limits

The lithium chemistry provides long shelf life but cannot be recharged and must be replaced when voltage drops below the motherboard threshold. It operates within the narrow voltage window required by the RTC circuit, so no substitute chemistry is suitable. Extreme heat or physical damage will shorten its useful span.

Simple motherboard swap

Installation requires opening the laptop chassis, locating the coin-cell holder on the motherboard, and pressing the new cell into place with correct polarity. The only common error is inserting the battery backwards, which prevents the RTC from holding time. No soldering or software configuration is needed.
