DBTLAP CMOS Battery for Satellite P100-227

This DBTLAP lithium CMOS battery replaces the BIOS RTC cell on Toshiba Satellite P100-227 laptop motherboards. It restores system time and BIOS settings when the original coin cell fails. The unit is tested before shipping and arrives new. It is a motherboard component, not a main laptop battery.

For owners of a Satellite P100-227

This part suits anyone whose Satellite P100-227 loses the date or BIOS configuration after power-off. It will not help if the fault lies elsewhere on the motherboard. Builders working on other laptop models or on desktop boards should look at something else.

Single replacement cell included

The package contains one lithium CMOS battery ready for installation. No cables, brackets, drivers or software are supplied. Fitting the cell restores the real-time clock and CMOS memory retention without additional accessories.
