    I have being trying to diagnose a fault with a laptop, some over heating problem. I have used a diagnostics card it keeping spitting out the error code 'AE' which means clear boot flag. I'm guessing the bios is performing its own checks and intefering which the card checks.

    What can i do rectify this. Manuals not very good and i been trying to google it but to no avail..

    Hardware= diagnostic card plugs into the parallel port of the laptop powered by the usb port and has a two digit display, Dell c640 laptop


    If any one can help or set me straight i be grateful.

    Never had a good experience with diagnostics cards. All the ones I've seen are pretty useless and simply don't work well, if at all. Most moderen PCs has diag cards built in on whether it's beep codes or the diag LCDs on the back of most modern Dells. If the PC is having an over heating issue a diag card isn't gonna help anyway.

    To fix a laptop that is over heating you should open the laptop up and blow the dust out of the laptop paying special attention to the heat sinks and fans. While it is open make sure the fans are spinning and that the heatsinks are in place and securly attached.

    What are the symptoms the laptop is having any? Maybe it's not just overheating?

    Thanks for your interest.

    The dell just cuts off dead after a certain amount of time. First cold start last up 20 mins before cutting off, if you try to re-boot it again lasts a few minutes. original thought it what the cpu cooling fan not coming on but the owner says it definitly spins after a while. Then i replaced memory with known good modules, and booted just into Bios so hardrive is not started, but it still cuts off. Either he imagined the fan spinning or some other component tripping off. I suggested a motherboard replacement just to keep him off my back, but then again I cant run from the problem still wanna resolve it somehow.

    Regards
