  1. hi hopefully someone can help me with this.

    i have a Mitac 7521T - laptop with windows xp the laptop was working fine and shut down the night before when i put the laptop on the next day the screen was blank like nothing on it at all.

    the laptop turns on the light comes on and i can hear the fan turning..... the cd/dvd drive wont open.

    i have removed the battery for 2 days and then put it back in and the same thing but what i noticed is the laptop will only work as above from the power lead it doesnt start from the battery at all.

    i have tried connecting my LCD screen from my PC to the laptop and that hasnt made any difference.

    is there any method of repair or is it for the bin i bought the laptop reconditioned and it worked fine for over a year running xp playing games internet etc.

    Any help would be great but please take note of my username i,m know next no nothing about repairing/upgrading or anything like that.

    Thanks.

    Remove the battery and power lead
    Hold down the power button (on the laptop) for 30 Secs
    Re-insert the power lead only
    Turn on

    If it works, consider purchasing a new battery

    I don't think it's the screen, as it's basically not powering up (POSTing) at all.

    You will need to:
    Detach any externals (hopefully already done ie mouse; Printer...)
    Reseat you Ram (referring to your manual)
    Possibly reseat the CPU (this can be a tad difficult, ie you need to remove covers, and apply new thermal paste)
    Check or reconnect or internal connections (also check for loose screws)

    Here is a good technical Manual http://www.eserviceinfo.com/download.php?fileid=22168
    Which can be used to confirm the real internal electronics.

    Or get a qualified tech to pull it apart (safely)

    There is nothing connected to the laptop externally at all.

    i will try everything i can you have suggested though my knowledge is limited as i mentioned above.......................... if all else fails i will take it too a Latop repair shop it just seems strange that it worked perfectly well the night before and the next day the blank screen etc.

    thanks for your reply.
