I have a V5 IO, that is completely dead. I took some voltage test and so far have
at D15, one end is 19v and the other is 5v
at C257, one end is 5v and the other is 0
at fuse 1, 19v at both ends.
I tried remove CMOS battery, shorting end and replace battery
I tried holding down power button, providing power
I swapped the CPU.
Any help would be appreciated.
