Do not buy a Satelite Laptop...Model # M645-S4045 Their warranty is horrible! I bought this Oct 24, and had problems from the get go. Called Toshiba, sent it to repair, got it back and now they are making me send it in again...haven't even been able to use it. Keep shutting off, screen keep going on and off, now they are making me send it in again!!! I have had it in my hands less than 30 days, very upset, will never ever buy another Toshiba product of any kind!!! read full review »
