Compatible replacement for Sony VAIO VGN-TT11M

This DBTLAP CMOS battery is a lithium coin cell built to fit the Sony VAIO VGN-TT11M motherboard. It supplies the low-voltage power that keeps BIOS settings and the real-time clock alive when the main battery is removed. The unit is tested before shipping and arrives new.

For owners with reset BIOS clocks or checksum errors

If the laptop loses its date, time or boot order after every shutdown, this cell restores normal operation. It will not help if the fault lies in the main power pack, the charging circuit or a damaged motherboard trace. Buyers who need a primary laptop battery should look elsewhere.

Single battery in the package

The box contains one CMOS cell only; no tools, cables, adhesives or software are supplied. Installation requires opening the chassis and swapping the old coin cell, so the buyer must be comfortable with basic disassembly. No configuration utility or driver is involved.
