Actually my initial report was somewhat inaccurate. When pressing the power
button during sleep the following happen:

1. laptop seems to wake up, screen remains blank
2. after about 1 or 2 seconds from the press the laptop reboots itself without
me doing anything
3. after the self triggered reboot the screen remains blank/black and looks as
if the laptop doesn't do anything while the fans keep on spinning


In order to recover I have to press the power button (long press). After these
things occur, the led indicating sleep remains lit (during sleep it flashes). I
tried to boot in Windows and put the laptop in stand-by then recover in the
hope it will shut down the led, but it didn't (after recovering from sleep, the
led was on).

I suspect you are talking about a single test in this paragraph as well as in
the previous one. If not, please elaborate.

I stopped acpid (invoke-rc.d acpid stop).

The laptop didn't resume (see details above). No dmesg_after was written.
