DBTLAP CMOS Battery for HP Mini 5102

This lithium coin cell is built for the HP Mini 5102 motherboard. It keeps the real-time clock and BIOS settings alive when the main power is off. The part is aimed at owners of that model who see time drift or CMOS checksum errors on boot.

Replaces a depleted or leaking original cell

Swap it when the system clock resets after shutdown or when BIOS defaults reappear at every start. The jump is worth it if the laptop shows those symptoms and the existing battery reads below its nominal voltage. A fresh cell restores persistent configuration without a full board repair.

Fits the HP Mini 5102 motherboard holder

The battery ships tested and ready to install in the designated socket. It frees the board from repeated POST warnings and lets the firmware retain boot order and hardware parameters. No extra cables or adapters are required for the swap.
