we've had a dell inspiron laptop for about a year. it had a new battery a few months ago. it used to turn itself off about once a day but now its all the time! it will turn itself off in the middle of something whether it be browsing the net, playing itunes, writing an essay, if you've popped away for a minute. i have a feeling it may be because the charger is really hot but i'm not sure. it has an external hard-drive plugged into it thats always on at the same time and currently a telecom t-stick thats brand new.

any ideas on what i can do? i spoke to dell customer support and they changed the power saving options to never turn off! it didn't work.

we want to use itunes on this computer to play at our wedding but don't want it turning off every half hour or so!!!
