[ltp] Blocked start up for X220

[Athanasios Velios]

Hello,

A recent strange problem with my X220 tablet is that when I shutdown 
from the command line after Ctrl+Alt+F1 while a gnome session is running 
at Ctrl+Alt+F7, the computer shuts down but when I press the power 
button for it to start up again the Bluetooth, Wireless and Disk 
activity lights flash for a couple of seconds and nothing happens (i.e. 
the monitor is black and the computer turns off immediatelly). The same 
happens if I force turn off the laptop from the power button. Attempting 
to turn on the computer by pressing the power button a few times (and 
trying long presses as well) eventually gets the computer started as 
expected (after say 5-6 attempts). Any idea what is blocking the 
computer from starting up?

Thanks

Thanasis
