Compatible CMOS Battery for HP TouchSmart tm2-2151nr

This DBTLAP lithium CMOS battery replaces the motherboard RTC cell in the HP TouchSmart tm2-2151nr. It keeps the system clock and BIOS settings alive when the main power is off. The unit is new and tested before shipping. It is intended for laptop motherboards, not the primary laptop battery.

Replaces a Dead or Leaking Onboard Cell

Swap this in when the original CMOS battery no longer holds a charge, causing date resets or BIOS errors. The jump is worth it if the laptop loses time after shutdown or refuses to boot with a checksum failure. A fresh cell restores reliable startup behaviour without board-level repair.

Fits Directly on the Motherboard Header

The battery plugs into the existing CMOS header on the TouchSmart tm2-2151nr mainboard. No soldering or adapter cables are required. Installation frees the system from repeated BIOS reconfiguration and preserves boot-order settings across power cycles. One battery is included in the package.
