Compatible HP Mini 110-3500 CMOS Battery

This DBTLAP lithium CMOS battery is designed for the HP Mini 110-3500 laptop motherboard. It supplies power to the real-time clock and BIOS memory when the main battery is removed or depleted. The unit is tested before shipping and arrives new in a single-unit package. It addresses the specific need for a motherboard-level replacement rather than a main laptop power cell.

Replaces Faulty Motherboard Coin Cell

This component replaces a faulty, cracked or broken CMOS battery that causes system time loss, BIOS checksum errors or boot failures on the HP Mini 110-3500. The upgrade is worth it when the original cell no longer holds a charge and the laptop loses date and time settings after every shutdown. It is not for buyers who need a main laptop battery to power the whole system.

Maintains BIOS Settings Under Continuous Off-State

The lithium chemistry provides a stable voltage to the RTC circuit during long periods when the laptop is unplugged and the main battery is absent. It sustains BIOS configuration data and the system clock reliably over the cell's service life rather than in short bursts. The battery is not designed for high-drain applications or to power any active components beyond the low-current CMOS circuitry.

Questions about this item

What laptop models does the DBTLAP CMOS battery for HP Mini 110-3500 fit?

This CMOS battery is compatible with the HP Mini 110-3500 laptop motherboard. It replaces the original BIOS RTC coin cell that maintains system time and firmware settings when the main power is off.

How do I install the CMOS battery in my HP Mini 110-3500 and what step is often missed?

Power off the laptop, unplug the charger, and remove the main battery. Open the base cover, locate the coin-cell socket on the motherboard, unplug the old two-wire connector, and snap in the new one. The step often missed is forgetting to reconnect the main battery before closing the case, which leaves the RTC unpowered.

When will the DBTLAP CMOS battery need replacement in an HP Mini 110-3500?

A lithium CMOS cell typically lasts three to five years. Replace it when the laptop loses the date and time after every shutdown, shows CMOS checksum errors on boot, or BIOS settings revert to defaults.
