In Post #20 (Your OP) you said
Wanted to jump in here that i have the exact same problem. On a cold boot, the sleep will work once (ie. shut down, flashing LED on power-button indicating sleep state and fans/other lights shut down). However, on subsequent sleeps, the fans stay spinning and the power is clearly on (though monitor is turned off). If you wake it from this state (S5?), it's as though you woke it from sleep. The command powercfg -lastwake is correct in reporting what woke the computer.
Maybe i misunderstood, but that sounds different than what nsainfreek (OP) said.
That's why i said your problem sounds different.
MY OPINION on starting your own thread: This thread is still not solved for nsainfreek, and nsainfreek may start posting to this thread again.
If you are posting to the same thread, it could be very confusing for everyone.
Trying to figure out who said what to who, who tried what, what happened, ...
Have you tried everything already suggested to the OP in this thread?
Is your hardware and software identical to the OP?
Anyone trying to help you would have to read this entire thread, probably guessing as to what you tried, or ask you the same question again.
If the OP solves the issue and you do not, should the thread be marked as solved?
If you solve the issue and the OP does not, you can not mark the thread as solved.
