CMOS Battery for Sony Vaio VGN-FS315H

This lithium CMOS battery replaces the BIOS RTC cell on the motherboard of a Sony Vaio VGN-FS315H laptop. It restores system time and firmware settings that are lost when the original battery fails. The unit is supplied new and tested before shipping.

Questions about this item

Does the DBTLAP CMOS battery need a specific connector already on the Sony Vaio VGN-FS315H motherboard?

Yes, it plugs directly into the existing CMOS header on the VGN-FS315H motherboard, so that header must be intact for the battery to work.

Will this replacement CMOS battery keep the VGN-FS315H clock and BIOS settings if the original battery holder is still in place?

The battery fits the same footprint as the original cell, so it will maintain the real-time clock and CMOS settings while the original holder remains on the board.

After installing the battery in the VGN-FS315H, how can I confirm the CMOS is holding charge?

Power on the laptop, enter BIOS, set the correct date and time, save and exit, then fully shut down and restart; if the clock still shows the right time, the CMOS battery is functioning.
