I'm working on an Asus U56E for a friend. I'm having problem getting power to the laptop to run or charge the battery.
I know the power adapter is good, as it's putting out 19.5 VDC. But, when I plug the adapter into the laptop (without a battery installed), the laptop won't power on.
So, I verified that it WASN'T the power port, and verified that I am getting 19.5 VDC on the motherboard side of the power port. With a battery installed, the laptop will power up and work properly. However, the battery is not getting a charge current, from the laptop.
Finally, the last time the entire unit worked properly, (meaning the battery was accepting a charge from the laptop), the power adapter got really hot.
I suspect that the DC/DC converter on the motherboard may have given up, resulting in the need to replace the motherboard. But, would like other thoughts on this problem.
