Welcome to a laptop battery specialist of the Sony laptop battery
Toshiba's keyboard design was a bit different from other ultrabooks with a wider design that offered more space and being splash resistant. The overall feel of the keyboard falls somewhere between comfortable and problematic. This probably has to do with the short throw of the keys and the design that lets a fair amount of light out from under the keyboard backlight. The trackpad is a bit on the small side for an ultrabook but does offer dedicated left and right buttons which avoids the awkward click recognition problems of many integrated button designs.
The battery such as Sony VGP-BPS10 battery , Sony VGN-FZ battery , Sony VGP-BPS8A battery , Sony VGP-BPS19 battery , Sony VGP-BPL19 battery , Sony VGP-BPS20 battery , Sony VGP-BPS20/B battery , Sony VGP-BPS20/S battery , Sony VGP-BPS12 battery , Sony VGP-BPL12 battery , Sony VGN-Z21XN battery pack still remains a 47WHr capacity battery pack that is fairly typical of ultrabooks.
