Does this shutdown happen while using it, or when it's idle for 30 minutes. Check your power settings.
I have recently upgraded my acer aspire e1 531 laptop from pentium to i5 all worked well however whenever I boot up my computer I have 30 minutes before the computer shuts down without warning. I have seen other people with this problem but no solution.It seems to be on a timer in the bios. Can anyone help.
Thanks,
