I have a lenovo T440p laptop that i have been using for 6 months now. newly the laptop often and unexpectedly turns off rather then going into sleep mode after i close the lid.Also, sometimes, after i close the lid the display turns off and the laptop becomes irresponsive but do not enter sleep mode. the only way is to force reboot the laptop. i have installed all the required updates proposed by the thinkvantage utility but the problem is persisting.
what could be the reason for this behaviour and how could it be solved?
