Hello! I am in possession of an Acer Aspire V5-531P-4878 recently wiped when given to me that is running Windows 8.
Running the 64-bit version of Windows 8
Intel Pentium 987 (1.5GHz)
8 gigs of RAM
The complaint is the laptop will randomly lose power and shut off by itself. I have observed this while booting up and while in the desktop browsing things. Unsure if jostling it can contribute to the issue.
Ran MemTest86 and it found zero errors.
Interesting observation is I have had zero shutdowns while running MemTest86 (off the DVD drive) or while messing around in an Ubuntu live disk (also off of the DVD drive). This is not to say that it won't happen.
