i have a 2.5 yr old lenovo 3000 n100 last week it just turned off while i was online...i was thinking ok since the battery is shot i probably pulled the power cord out by mistake so i made sure it was fully in i restarted 2 min after it turned off again so by now i'm like wtf i just got a new power cable so i tried a diff one and same thing it will load up and then after a few or even few seconds it'll turn off and i can turn it back on but only for a few moments........whats the problem here and can it be fixed or should i just start saviing for a new laptop becuz if at all possible id like to keep this i just built a desktop so i have all the power my laptop is just for internet and email so if at all id like to fix this one but if its come to its end ill accept that get a new 1
