First, thanks for any help you may give.
My problem is: from several days ago, my 3 year old thinkpad T40 cannot load the windows when turned on. I noticed the fan is working but the HD seems not. For maybe 1 trial of 10, the windows can load and I would enter the system, but it becomes dead even with small vibrations of the machine.
I know nothing about the hardware. But I suspect something is loose inside. Or is it only a software pb? I have a strange experience happened just before this pb. On that day I suddenly suffered a screen change (lose 1028 resolution and becomes to 640, saying something related to display drive doen't work and need reboot).
