DBTLAP CMOS Battery for Satellite Pro P100

This lithium CMOS battery replaces the RTC backup cell on the Toshiba Satellite Pro P100 motherboard. It keeps the system clock and BIOS settings alive when the main power is removed. The part is new and tested before shipping. It is intended for technicians or owners servicing this specific laptop model.

Replaces a dead or leaking original CMOS cell

When the real-time clock loses time or BIOS settings reset at every cold boot, the original battery has failed. Swapping it restores persistent configuration without a full motherboard change. The jump is worth it whenever the laptop shows checksum errors, date drift or "CMOS battery low" warnings on POST.

Simple two-wire plug-in installation

The battery ships with its connector attached, so no soldering is required. Common issues are routing the cable away from fan blades and ensuring the polarity matches the header. Forgetting to reseat the connector fully after reassembly is the most frequent cause of a repeat fault.

Questions about this item

Will this CMOS battery fit inside the Toshiba Satellite Pro P100 chassis?

It is built as a direct replacement for the Satellite Pro P100 motherboard, so it matches the original form factor and connector.

How do I install the battery without losing BIOS settings?

Power off the laptop, unplug the AC adapter, open the case, unplug the old battery lead, connect the new one, then reassemble — skipping the power-off step is the common mistake.

When will this lithium CMOS battery need replacing again?

Lithium coin cells typically hold charge for several years; replace it when the system clock drifts or BIOS settings reset on every boot.
