Suspend problem

Question

Recently, my laptop does not suspend though I saw it going into Suspend mode when I closed the lid of my Sony Vaio. The PC just suspends for 1 second then lights on immediately. How can I resolve this problem?

Answer 1

1. Go into screen settings

2. Make sure the "Lock Screen After:" setting is set to anything but "screen turns off"

   This option prevents the system from fully suspending

Answer 2

Go to Power Settings via the task bar or System Settings and see what option you have for "When the lid is closed".

I have a Sony Vaio and it works fine for me. What series are you using and what release of Ubuntu?

Suspend Fix for Laptop Using Ubuntu Had same problem and fixed with this script. Seems like it is a common problem, not sure why they don't fix it.
