Product Identification

This is a DBTLAP lithium CMOS battery built for the HP Pavilion dm3-1040eg motherboard. It supplies the low-voltage power that keeps BIOS settings and the real-time clock alive while the main pack is removed. The cell arrives new and tested, ready for direct installation.

Compatibility Guidance

Owners of the dm3-1040eg whose system clock resets or who see CMOS checksum errors will find this the correct replacement. It is not a main laptop battery and cannot power the notebook itself. Buyers needing a primary power pack or a different form factor should look elsewhere.

Decisive Specification

The battery uses lithium chemistry in a coin-cell format sized for the dm3-1040eg motherboard holder. Matching this exact chemistry and physical layout is the single factor that decides whether the part will fit and function.
