Laptop freezes, but works fine only when holding any key

Postby jurisuns » Sun Oct 17, 2010 8:56 am

My laptop works fine only when I continuously press and hold any key on the keyboard or the frame near the touchpad.

Laptop type: Fujitu-Siemens Amilo M 7440G
OS: Windows XP SP3

If I (re)boot the laptop it always freezes in the “XP startup screen”. When I press any key on the keyboard, hold it, the booting continues… When I lift my finger and release the key I was holding, the booting stops, press down any or same key on the keyboard again and the booting continues, when booting complete, the touchpad and keyboard will not work, when I again press and hold any key I can use the touchpad and type/use the keyboard… to be short my laptop works perfect if I press and hold (doesn’t have to be hard, even when pressed gently) any key on the keyboard, or if I move and hold up or down the connection place where the battery is connected to the motherboard (it's possible only when the battery has been taken out ).

From visiting the Fujitsu-Siemens website/forum I know that there is at least one more user of the exact same laptop that has the same problem.

I’m very interested/curious on what you will have to say about this and by all means very much obliged for it.

Thank you.

Sounds like a fissure in some platine underneath the area you press (even if only gently).
Since the problem doesn't occur until the Windows logo is displayed I guess this fissure has something to do with the graphics chip (during that the graphics driver is loaded). If I'm right, the laptop might boot fine in safe mode without any pressure workarounds, since the graphics driver won't be loaded.

Sorry, just an attempt of diagnosis. Even if everything turns out as I suspect, I can't offer any reasonable solution.
