A lesson to laptop owners

Having practically just burned myself, here's a (potentially quite obvious) tip for laptop owners - make really sure the laptop has actually turned off before putting it in your bag. I usually set it shutting down, close the lid and start packing up. I just went to get my laptop out of my bag (4 hours after leaving work) and though my bag felt warm, but was a bit confused as it wasn't next to a radiator (and really, with the weather we've had it wouldn't be on anyway). Reaching in to lift my laptop out of the pouch built into my backpack is the point I came close to a burn. Seriously. The laptop had failed to shut down (one of those 'program not responding, end now?' messages) and in the closed confines of a backpack there was no route for hot air to escape at anywhere near an acceptable rate - cue one VERY hot laptop. Luckily no damage seems to have been done. It was still running - impressive by itself given it's been 4 hours since it was unplugged - and has logged back in fine. Here's hoping I don't make that mistake again :)
