DBTLAP CMOS Battery for Portege Z930

This DBTLAP lithium cell replaces the CMOS BIOS RTC battery on a Toshiba Portege Z930 Ultrabook motherboard. It is a direct-fit spare for the coin-type cell that keeps system time and firmware settings when the main power is off. Each unit is tested before shipping and supplied as a single replacement battery.

Fits Portege Z930 owners only

The part suits anyone whose Portege Z930 loses the date, resets BIOS options or shows a CMOS checksum error at start-up. It will not help if the fault lies with the main laptop battery, the charging circuit or any other power component. Buyers needing a primary power pack or a different form-factor cell should look elsewhere.

Lithium coin cell chemistry

The battery uses lithium chemistry to provide the stable low-current supply the real-time clock requires. No other voltage, capacity or connector detail is provided. Verify that the original cell matches this chemistry before ordering.
