Won't stay suspended

If your laptop wakes up on its own a minute or two after suspending (just long enough for you to put it in your bag where it can wake up and start overheating!) then disable "wake from USB" -- presumably the keyboard, trackpad, or some other internal component is waking up.

To disable "wake from USB":

echo XHC1 | sudo tee /proc/acpi/wakeup
