Dell 3542 power problem

[mafioso]

My friend's got an Inspiron 3542 with i7 and 840M inside but unfortunately just when the warranty is over he's got a big problem. The laptop's power is down if he uses the laptop for a while. I mean, he cannot turn it on for a while. And after letting it rest for a while it will be able to be turned on again. Nobody can stand such a situation. If anybody has an idea about this then please tell me what we could do. Thank you so much.

 

Additional information: The mechanic man said he tested it and it worked just fine but when we take it home the problem rises up again. Very frustrating

seems like a typical overheat issue..

 

have you used compressed air to clean out fans and heatsinks? sometimes you have to disassemble the computer to be able to properly clean out dirt and dust from the fan and heatsink.

it could also be bad thermal paste.. get some new proper paste and remove and replace the thermal compound on the laptop..

we haven't yet tried cleaning the laptop or changing the thermal paste because actually it's a fairly rare situation in which one needs to do so with a laptop. I previously had a 3542 with i5 and 820M rocking for about three years before I decide to let go for a change and TBH I let it run several days a week without switching it off. But your idea is a very nice one that I might as well consider and probably will give it a complete clean-up very soon.

 

Oh and once the mechanic man told us it was the power IC problem inside the board, and he changed it, no miracles happened. Very sad actually

does it run ok (ignoring the issues you mentioned) without the battery installed?

you could also take your vacuum claner and a make a cone shape with a piece of paper and try to clean out all air inlets, fan inlet ans heatsink..

I told my friend to use the laptop without the battery but the result is still negative
