I have a Lenovo T440 i7-4600U which powers on but doesn’t display anything. I get a sequence of beeps (5 short beeps, a pause, and 5 short beeps again) and it goes quiet, though the system is still on. I’ve done the hard reboot (Take out the battery and charger, then hold the power button down for 20+ secs and turn on again) and checked for any faint lights. Also checked the ram. I think theres something up with the motherboard, but I don’t know what or how to fix it. Anything would be very appreciated !
@fssaya five short beeps and a blank screen is the post code for a failed motherboard. Do this Take out the battery and charger, then hold the power button down for 20+ secs and turn on again once more but remove your RAM as well. Then apply one module only and use different slots than they were in.
