I'm currently trying to repair this Acer Aspire 7741Z-4433 for a friend of mine. I've checked the power cable with a multimeter and its appropriate and I can see the charging LED indicator when it is plugged into the computer, but the computer never powers on. I've pulled the battery and power supply and held down the power button for 30 seconds. I've reseated the RAM and the HDD and the optical drive as well. Anyone have any suggestions?
Hope I'm wrong bt seems that motherboard is dead... 17" paper weight.
Does it gives any sign at all? Beeps, disk start, vents boost??
Try to find a new motherboard or new laptop and sell those good pieces.
