DBTLAP CMOS battery for HP Pavilion dm3-2110sa

This lithium coin cell replaces the motherboard CMOS battery in the HP Pavilion dm3-2110sa. It keeps the real-time clock and BIOS settings alive while the main power is off. The unit is supplied new and tested before dispatch. It is not a main laptop battery and will not power the system.

Capacity and headroom for BIOS retention

The cell provides the low current needed for CMOS memory and the real-time clock for its rated service life. It cannot run the processor, memory or any peripherals. When the voltage drops below the threshold the date and time will reset and BIOS defaults will load. Replacement restores normal start-up behaviour.

Bundled accessory changes

The package contains one CMOS battery only. No tools, cables, mounting hardware or software are included. Installation requires opening the laptop chassis to reach the motherboard socket. The battery is ready to fit without additional preparation.
