Look at the power cord and make sure that the laptop has power. Sometimes the device dies and either the lightning panel was damage or the battery was damaged. Look upon that and if it turns on and does not show anything on the screen try plugging to the HDMI to another device in case it is just the screen.

Check if the light on charger stays on when its plugged into the system.If yes,disconnect the charger,remove the battery,press and hold down the power button for 30 seconds.Reconnect the battery and charger,turn on the system and see if there is any change. For better and effective solution please watch troubleshooting instructions in Lenovo ThinkPad T440 Manual.

Are there any lights or sounds when you turn the computer on? If it is plugged into the ac adapter, is there a light showing that it is charging?
