    Default Laptop overheating?

    My Father in laws laptop has started shutting about 30 seconds after it boots up and then becomes unresponsive for about 2 hours. It's plugged in so I don't think it's an issue with the battery so I'm guessing it's overheating. Does anyone have any idea what else it could be? It boots up fine and is OK for the 30 seconds or so it is on but once it shuts down, that's it. It's an Windows 7 HP laptop if that's of relevance.

    Cheers

    Certainly sounds like an overheating issue. Is the fan working, can you see or hear it?

    Could be Fan not working or if it kicks in very early, I've found a lot of Laptop air intakes/ fans covered in dust which gets them hot real quick and shut down. Also worth checking the air path isn't being blocked.

    Could do with a model number bud, I had a hp 6710b which would turn on fine but then became unresponsive when windows had loaded .
    I found it to be the power supply had gone bad as they carry a 19vdc and a 5vdc .... the 5v had died and so when the laptop required more juice (loading windows) the sense cable wasn't letting the power brick know to up the ampage and this slowed it considerably but would still boot as it had the still working 19v supply .
    Replacement adapter fixed the issue ... b3

    I'm sure some particular model HP laptops had issues with the heat sync not sitting right on the CPU after a while, I read that people were using copper shims to to rectify the problem

    I've helped a 3 HP laptops (well one was compaq, same thing) using this method. The thermal pads were totally wrecked/melted and the shim did the trick nicely. Have no idea where I got the idea but remember it was a guy (maybe a blog?) fixing a hp G60 and he had plenty of pictures.

    Inside my laptop gives some nice disassembly walk-throughs for the older HP models with the overheating issue.

    TJB - does his laptop make an almighty noise or none at all? If it's noisy then the vents might just need a good cleaning (compressed air wont do it), if theres no noise it might be a dead fan, easy to find on ebay. If theres black screen it might be an issue with the graphics card.

    I had a hp6735s that overheated, after much discussion and wasted time with both HP and retailer, ebuyer who after months refunded part of the cost of the laptop, HP who initially told ebuyer they could fix it then couldn't.

    Anyway the below forum was a great source of help and guidance.

    Would look at cleaning the fan first I have done loads of laptops like this theres usually a nice layer of fluff covering the out take and this then just makes the thing boil.

    Depending on age of laptop (design wise) you can usually take off the keyboard on a HP and dig it out using a small screwdriver, spinning the fan and blowing thru the out take.

    It's an HP G62. As soon as it's switched on the fan is really noisy and a lot of air is sucked through and then it slows down after 15 seconds or so. It's still on though. After about a minute or so, the laptop just shuts off and then is unresponsive for a couple of hours.

    Repaired one of these a couple of weeks ago. Practically the same issue.

    It's going to be GPU overheating and laptop going into self-preservation mode.
    Needs stripping down and investigating. Paste has dried out or thermal pad deteriorated

    Load the laptop to BIOS and see if stays there for more than 30 seconds. It wont, so get your screw drivers out.

    Little late to the game but if it's the thermal pad you could replace with thermal paste and then add padding on top of the heat sink to keep everything nicely in contact.
