Hello all
Last week I lifted my U400 from the desk and it shut itself off, just to clarify it didnt 'shut down' the OS but rather
powered itself off completely in an instance. Since then this has been happening with greater and greater frequency.
At first I suspected overheating so I installed a couple of programs for monitoring fan-speed and cpu temperature and found nothing out of the ordinary. Then I turned my attention to the hard drive but having booted the laptop from a Live Linux USB stick the problem persisted.
Then I noticed that the computer tended to shut itself down when it was moved aprubtly, turned over or on its side or even gently tapped underneath. Each of these actions would cause a complete and abrupt shutdown. I've noticed that where the device is most sensitive is underneath the front right corner - where I believe the battery is situated.
I opened it the other day and re-seated as many components as I could without voiding my warranty: the hard drive, the exposed memory, the battery itself, but to no avail.
So now I am left in a position where I cannot move my laptop or touch it with any degree of force without it powering off abruptly. Could it be that something is loose inside? or some kind of electrical fault?
Thanks
Derek
PS: The device is under the standard warranty but I am in Ireland so it takes around three weeks to get it fixed, I plan to send it back sometime in August but I was wondering if anybody had any insight into this kind of fault?
