Ask Lenovo E570 NM-B421 Turns on then off.
Can I please get some help, I can't figure this out. Board: NM-B421 Model: Lenovo ThinkPad E570 Charger plugged in, flashes 3 times. Power button pressed, it turns on 2 seconds then off. Occasional fan spin slightly until it turns off again. Never more than 2 seconds. Attached PDF shows...- SureCanDo
