Suspend functions ok intermittently. Some times it works fine, other times the computer does not enter the suspend mode (the screen gets blank, but the machine is still running and the ThinPad led is on, and there is no way out... no response from keyboard or mouse... the only solution is to switch off manually hitting and holding the power button), other times the machine does not wakes up from suspension mode.
