I have a Sony Vaio VPCCW1E8R.
I needed to do a BIOS reset and after BIOS reset
via unpluging the CMOS battery main battery is
not detected anymore.
Battery is original one and was working very well
until BIOS reset. Bios version is the latest from sony website.
Laptop will not power up with battery inserted, but it works
with battery out.
