so i had this problem...kinda fixed, i had it to where my laptop would go to sleep and stay asleep if i unplugged it from the power cable before i closed the lid. well i decided to reformat and now...it's doing it again. what happens is i close the lid or give it the command to go to sleep (or even shut down), and it sleeps for 2-3 seconds, then wakes right back up. i checked my network card settings, they're not able to wake it. i have nothing at all plugged into the laptop, not even power.
here's the real kicker though, i found a nifty command that tells you what last woke up your computer. it literally says that my computer was awoken by nothing.
there's one thing i could try...but i really don't want to. i could update the bios. i'm currently running v6.6, v6.7 is out and that miiight help me. however...when i reformatted yesterday and updated the bios to that version, my fan would not run at anything but 100%..and it was annoying as shit. could not get it to stop for an hour, was tired of trying, so i just reformatted again. so i'm nervous to try that again...cuz i don't wanna have to reformat this thing a 3rd time.
so anyone got any ideas?
