Welcome to a laptop battery specialist of the Toshiba Laptop Battery
Toshiba's second generation ultrabook is essentially a very minor update to their first generation Portege Z835. It still retains its extremely lightweight design at just two and a half pounds that is lighter than just about every ultrabook on the market. The downside is that this means it uses the same boxy rather than tapered design that gives it a more dated look and it doesn't feel as sturdy as mostly from its lighter overall weight.
The big change in the Portege Z935 is the move from the Sandy Bridge to Ivy Bridge processors. For the Z935-P300, this is the Intel Core i5-3317U dual core processor that is the most common of the new ultra low voltage processors used for ultrabooks with battery like Toshiba PA2487U Battery , Toshiba PA3107U-1BRS Battery , Toshiba PA3383U-1BRS Battery , Toshiba PA3384U-1BRS Battery , Toshiba PA3285U-1BRS Battery , Toshiba PA3191U-1BRS Battery , Toshiba PA3166U-1BRS Battery , Toshiba PA3331U-1BRS Battery , Toshiba PA3098U-1BRS Battery , Toshiba PA3084U-1BRS Battery , Toshiba PA3399U-1BRS Battery , Toshiba PA3395U-1BRS Battery . In terms of performance, it does do a bit better than the i3-2367M from the past model but it isn't a huge improvement. With the 4GB of DDR3 memory, it offers sufficient performance for the majority of users. Only those that are doing very demanding work such as desktop video editing are going to have issues and in those cases, they probably want to look beyond an ultrabook.
