Thanks for your reply i tried the link thanks and it will not even boot up from a boot disc so i am thinking that something has came loose. This laptop is so complicated to get into lol i have taken the screws out of the back, and i don't see how it opens i tryed popping the top open but it seems to be fused half way up..so if u know how to open the casing on a thinkpad 390 x i need help don't want to break anything to force it open im sure when i find out ill feel like a big dummy
