Lenovo T400, had no problems with sleep mode until upgrade from 10.04 to 10.10. Now every second or third time entering sleep mode either by closing lid or typing FN-F4, the laptop locks up, the little moon-shaped light blinks incessantly, and I have to hold down the power button to kill it and restart to recover.
