Alienware randomly wakes from sleep(or does it)

[Jared_Reabow]

So over the years I have had laptop seemingly randomly wake from sleep with no obvious reason.

What made the occurrence stranger is that this is usually when the lid is closed and windows is set to sleep with the lid shut.

Also after waking it would then refuse to stay asleep if put to sleep again.
 

So after being puzzled for years blaming the occurrence on things like a wireless mouse being clicked or the keyboard being pressed in by the screen I believe I have finally found the reason.

As it turns out when in sleep mode if the battery gets too low the machine will power back on!
After testing this on an Alienware 17 R4, an old HP g6 and friends Razor I can confirm they all do this.
 

Now I can sort of understand why but also find it damn confusing.
If it were logical, it would turn back on to then go immediately into hibernation (which uses almost no power) as opposed to stand by (which uses quite a bit in comparison).
However this does not happen, the machine simply turns on and bakes in my bag or chueches along on the desk until it gets a critically low battery and then sometimes hibernates and sometimes hard shuts off.
It could potentially stay in stand by for several more hours if it did not power back on then sit there for 40minutes until critically low battery.
However, upon thought, I realized as the battery gets older the time/percent charger will reduce.

With modern SSD's standby is almost not necessary with resume from hibernation taking 15s as opposed to 60s + with a HDD however going into hibernate is pretty slow.
So my solution is to make the power button hibernate and lid close standby, that way when the machine powers on randomly I can force hibernate immediately and potentially have 40 or more minutes use if needed as compared to it refusing to turn back on until AC is connected.

 

hell this would make for an interesting video LTT.
