Hi i have a friends laptop i aim trying to repair:

Firstly it boots up into windows and after about 5-10 mins of use powers itself off. i have come to the conclusion it could be the cpu overheating due to a faulty heatsink / fan?

or could it be the cpu sensor i am about to purchase a second hand heatsink that is tested as working but am i going to be wasting money could it be the cpu sensor or do i need to remove heatsink and re-apply thermal paste?

HI Dan and :thumbsup: to the BC forums!

First, we need a little bit more info about your laptop, such as brand and model number, if you could supply us with that info, we can assist you better.

Second, it certainly would not hurt to carefully open the laptop's bottom and making sure all vent openings are clear of any dust and the fan is spining freely.
If you decide to remove the heatsink, make sure you protect the unit from any static electricity discharge from your body, by grounding yourself to the metal frame inside the unit at all times.
Adding some new heatsink compound wouldn't hurt, using alcohol on a clean lint-free rag you can remove the old compound. Just be careful not to rub too hard as to cause stress or damage to the processor or board. Then add enough of a bead of new compound so it spreads out evenly over the processor's metalic surface.

Once you give us more info on your board and processor type, we can offer you more advice.

Thanks and best regards.
