My Toshiba laptop worked perfectly for three months or so in Ubuntu recovery mode but now it hangs/freezes every hour and when it's plugged in.
I spend eight hours a day on an average on my laptop. I just want it to last at least that long. If the laptop is not plugged in in recovery mode/regular Ubuntu mode, it freezes in five minutes and the screen becomes all weird.
It works perfectly with Windows 7 on battery but hangs instantly as soon as it is plugged in. Also now, a high CPU usage doesn't help anymore.
Any strategy or suggestions that I could employ to extend the duration for which it doesn't freeze?
A post on the Toshiba forums, A205 S4617 laptop freezes when ac power plugged in., describes the same situation as I am in.
