This device is not powering on at all. But the led 1 (Power) is on, but the fan is not spinning or any display or even beep codes. I tried removing the battery, using only AC Adapter, discharge static power holding power button and even to the point where I removed the CMOS battery. My guess is that the motherboard is dead. But I can't simply rely on my opinion. Hope you guys will be able to help me out. Thanks in advance
