Laptop waking up in bag? You are not alone :)

Laptop waking up in bag? You are not alone :) 14 Feb 2008 09:09

I read a very informative post today on "The Old New Thing" (well worth subscribing to btw) which I thought was particularly relevant for Darryl and Chris who have had no end of problems with the old "laptop wakes up in bag and burns my hands when I take it out" issue. Todays post from Raymond is all about how to use the powercfg command, which I must confess I had never heard of until now..

In a nutshell, to start looking at what can wake up your laptop, open up a command prompt and then run:

powercfg -devicequery wake_armed

This will enumerate all of the devices which can actually wake your laptop up. On my laptop there were actually a lot more devices than I would have expected, so to turn them off run:

powercfg -devicedisablewake "<your device name here>"

And like magic you now have control :) Of course, I take no responsibility for any strange new waking or sleeping behavior you enact ;)
