Recently I noticed that my laptop is, it looks like, somehow waking up from the suspend mode, when its lid is closed. I'm sure it goes suspend after I close it (I checked it this morning), but after some time when I'm back I hear it running again -- when I open it I see the login screen; if I press something and open it, I see something written in the password field. I use the latest updates and Fedora 19. My laptop is "HP 630". Can someone explain this behavior?

I would provide additional information, log reports, but I am not sure, what do you need.

I can think of several scenarios that might cause this to happen:

  • Have you got a faulty keyboard that is sending signals with the lid down?
  • Is there a BIOS setting for wakeup events that could be triggered? Perhaps a USB event or similar?
  • Does your laptop have buttons on the edge of the case or on the top that might have been triggered by accident - perhaps by picking it up or by an adventurous pet (cats like nice warm laptops to sleep on for instance).

Are you sure you shut it down correctly? Nothing happened to prevent it sleeping when you last closed the lid, for example.

Is this a one-off event? I would just keep an eye on it and see if it repeats, or perhaps even try to repeat it by waking it up manually with the lid still shut (plugging into usb ports or pressing any external buttons, etc.)

Yes! -- My external keyboard is to be blamed. Every time, when the computer is sleeping and I press any key, it wakes up. As of now, if no-one knows any better solution, I'm going to plug it out when suspending.

Thank you a lot!

Ideally you should unplug the keyboard before you close the lid. But you may not need to - just don't press any keys while it's in sleep mode.
