HP Pavilion DV3000 CMOS Replacement

This lithium CMOS battery is built for HP Pavilion DV3000 motherboards that have lost BIOS settings or system time. It restores the real-time clock and CMOS memory so the laptop boots with the correct configuration every time. The part is intended for repair technicians and owners who are comfortable opening the chassis to reach the motherboard coin-cell socket. Buyers who need a main laptop battery or a charger should look elsewhere.

Sustained Reliability

The cell delivers a steady 3 V output over its rated lifespan, keeping BIOS parameters intact during weeks of mains-off storage. It is tested before shipping to verify voltage and internal resistance, reducing the chance of a dead-on-arrival unit. No recharge cycles are involved; the battery is a primary lithium type designed for continuous low-drain service rather than periodic high-current bursts.

Thermals and Power Draw

As a coin-cell CMOS battery it generates no measurable heat and draws only micro-amps from the motherboard RTC rail. The component is completely passive and silent, adding no fan noise or thermal load to the system. Power consumption is limited to the tiny standby current required to maintain the real-time clock and CMOS SRAM.

Questions about this item

How much power does this CMOS battery draw while the laptop runs all day?

The lithium cell only powers the real-time clock when the main battery is removed, so its draw is negligible during normal operation.

What must I already have in the HP Pavilion DV3000 for this replacement to work?

You need the original two-pin motherboard header and the small cable that plugs into it; the battery ships with a ready-to-fit connector.

Will this CMOS battery fit older HP Pavilion models that used the same DV3000 chassis?

It is built for the DV3000 series motherboard layout; other models with a different header position or voltage will not accept it.
