Hey guys, my G4 cube appears to be a bit under the weather. You see, it turns itself on and off randomly. I powered it on, it stayed on for 5 minutes, then powered back off. After a minute, it powered for for 10 seconds then powered back off. Just now it turned itself back on, flashed the power button light a couple of times, and has been on for a bit. Expecting it to turn off soon. Any ideas?
