I recently installed Ubuntu 11.10 on a Sony Vaio Laptop. I'm trying to learn the Linux operating system.

I have a alight issue in that the computer randomly shuts down. It seems to go through the normal shutdown routine without user request. Something (and I don't know what) seems to be requesting the shutdown.

How can I work out what is requesting this shutdown?

Is this fresh installed system? Check the power settings that you select any shutdown option for power issue

If it does not solve the problem then we need your system log. Provide the system log if it can not solve the problem.
