I have got an Acer Aspire 5610z laptop and it keeps turning off randomly. I can be using the computer and it will suddenly just switch off. The switching off is like the power has been lost. I thought at first that it might be the power supply but I have checked it with a multimeter and it is fine plus I have waggled the cable around whilst the laptop is on and it seems to be fine.
I have checked 'Event Viewer' and the only evidence is an entry saying 'Windows recovered from an unexpected shutdown'.
I wanted to find out whether the problem is caused by software or hardware so I booted in to Ubuntu from a live cd. The laptop ran for 8 hours continuously, it has never made it more than about 2 hours on windows. This led me to thinking that maybe it was just a problem with the current installation of windows, so I tried to install vista again.
The vista installation gets to around 60% then the computer switches off without warning. I thought that maybe it some interrupt or command that the computer doesn't like and it might be triggered by an installation etc. so I have just finished installing Ubuntu on the laptop and everything is running very smoothly.
The laptop is not mine and the person who owns it needs Vista back on the laptop if possible.
Any help would be much appreciated,
Thanks
