I bought 17 April to replace the battery hs my toshiba laptop, I have received in time, but I just installed my return from vacation and the latter does not. Firstly a big thank you to sav anker for their professionalism and responsiveness, in fact it appears that the operation is not due and not bought me error occurs because a reference to the purchase. Anyway I recommend the brand products if only for the quality of their service. And if possibly someone could tell me where to find a L775-140 battery toshiba satellite him I'm highly grateful!
