My Ubuntu 10.10 on my laptop Lenovo T400 is not able to suspend or hibernate.
Whenever I click Suspend or Hibernate,
- the moon LED on the bottom of the lid flashes a few seconds, the screen quickly shows something like "some devices fail to suspend, error 5",
- and then the moon LED goes off and the display still has ambient light illumination. I suppose in suspend or hibernation state, the display should have no illumination, just like when the laptop is turned off, right?
- If I press any key, the unlock screen dialogue will pop out.
I searched a little on the internet, and installed 'acpi-support' according to some advice but it does not help. Any suggestions to solve this problem? Thanks and regards!
