after over a week of hell,my m1730  freezing and rebooting after resting for 3 hrs unplugged ..now all  that occurs on bootup is the capslock,numlock and svcroll-lock lighting up plus the power led..no hdd led no screen.The battery has had the problem with charging so it's almost empty and the led on the brick is on.Dead motherboard and or cpu?
