my laptop is an acer aspire 5630, 5 yers old, running just ubuntu. in the last few days, it did restart randomly in middle of work. 2-3 times. and when it restarts, and arrive to the login screen, it restart itself again... and then go normal for a while...
is it a hardware issue? related maybe to the power stuff? or is it the O.S ? or is it the kernel power issues?
ubuntu 11.04, updated, kernel: 2.6.38-10
thanks in advance.
