DBTLAP CMOS Battery for Sony Vaio PCG-41217L

This DBTLAP lithium CMOS battery is a direct replacement for the BIOS RTC cell on Sony Vaio PCG-41217L laptop motherboards. It restores the system clock and BIOS settings that are lost when the original coin cell is exhausted. The battery is new and tested before dispatch. It is not a main laptop power battery.

Replaces a dead or leaking motherboard coin cell

Swap this battery when the laptop loses the date and time after shutdown or shows CMOS checksum errors at boot. The jump is worth it if the machine otherwise runs well but forgets BIOS configuration or fails to keep the real-time clock. Do not buy this if the fault is a main battery that will not hold a charge or a power circuit failure.

Check the motherboard model and holder type

Confirm the motherboard is marked PCG-41217L before ordering. Verify that the existing cell uses the same two-pin connector and physical dimensions as the original part. This unit is a CMOS battery only and will not power the laptop itself.
