I have an Acer Aspire 5755g that will sit and run fine on my desk but whenever I try to lift my laptop to another location it will randomly shut down. It is not overheating because I can turn it back on straight away and it will sometimes happen if it is the first time I have turned it on for the day. The only thing that causes the problem is when I lift and move the laptop. It can sit at a desk fine or I can even bump/tap the laptop case on purpose and it will still run until I lift/move it to another location.

Windows 7 64Bit ultimate. Fully charged battery.

Does it happen if powered up just to CMOS or an alternative operating system like an Unbuntu LIVE cd ? –  user218791 Apr 22 '13 at 4:40
    
I don't have any alternative operating system to test this on sorry. –  WillNZ Apr 22 '13 at 4:54
    
But when you boot into the CMOS, the BIOS menus, does it still shutdown in the same manner? –  user218791 Apr 22 '13 at 4:55
    
I have not tested this. I will do that soon as I am leaving work now. Will there be any issues if it shuts down in the bios menu? –  WillNZ Apr 22 '13 at 4:58

This may be an issue due to damaged power connectors/cabling inside your laptop, or a loose battery terminal in the battery compartment, or may be an internal damage to the battery itself (cells may have got damaged due to physical jerks maybe). Testing if it shuts down at BIOS also may not make any difference as it shuts down due to physical movement, nothing related to Windows. What I can sense is most probably it is a hardware issue and your laptop should be checked for this by an authorized hardware technician.

I pulled the laptop apart and gave everything a wiggle then put it back together and it all works fine. I'll give you the answer as no one else left one. –  WillNZ Apr 30 '13 at 7:20
    
OK, then it might have been a loose internal power cable, which may have got adjusted while re-assembling the things. Still nothing sure. –  Zeeshan May 1 '13 at 8:25
