thinkpad x20

--- I have a problem of suspend mode.
Is as follows: when the ibm thinkpad x20 notebook goes into suspend mode, for example, lowering the LCD display when I try to return it and the screen does not show keypad locks. already installed the hibernation utility, did an experiment with CardWizard as it keeps the energy of the PCMCIA bus, but no conclusion.
encotrou anyone ever had this problem and a solution
Thanks
