What this battery is and who needs it

This DBTLAP CMOS battery is a new lithium cell built to replace the original RTC backup on a Sony Vaio VGN-FS415S motherboard. It keeps the system clock and BIOS settings alive when the main power is off. The part is tested before shipping and arrives ready to install.

Who it suits and who should look elsewhere

It suits anyone whose Vaio VGN-FS415S loses the date or throws a CMOS checksum error at boot. It will not help if the fault lies with the main laptop battery, the charger, or any other power component. Buyers needing a main power pack or a different laptop model should look elsewhere.

The specification that decides fit

Battery type is lithium, matching the chemistry required by the Vaio VGN-FS415S motherboard. The package includes one CMOS battery and nothing else. Verify the model number on your existing cell before ordering to confirm compatibility.

Questions about this item

Will this CMOS battery keep the BIOS settings on my Sony Vaio VGN-FS415S when the main battery is removed?

Yes, the lithium CMOS battery supplies power to the real-time clock and BIOS memory so settings are retained while the main battery is out.

How can I verify the DBTLAP CMOS battery is working after I install it?

Power on the laptop, enter the BIOS setup, confirm the date and time are correct, save and reboot — if the settings hold, the battery is functioning.

Does the package include any cables or tools for the VGN-FS415S installation?

The box contains only the CMOS battery itself; you will need a small Phillips screwdriver and possibly a plastic pry tool to open the chassis.
