Re: Thinkpad T420 resume from sleep via laptop lid doesn't work

Similar problem hier on my EEEPC since over a year:

Going to sleep (suspend-to-disk), then when it has to wake up, you can see, 
the memeory content is loaded into RAM, after that it shuts off and boots 
again from BIOS.

No problem with suspend-to-ram.

I filed a bugreport a year ago and mentioned this also in the forums, but 
since then, no one cared. 

Maybe you the trouble of the same reason like me. 

Runnig here debian/testing (32-Bit) , but saw it also in debian/stable.

 Maybe some day it will be fixed. Maybe not, who knows. :)

Best regards
