Hello, have an 820-2879 no liquid damage - does not chime and does not start .
voltage @ q7085 fluctuates from 16.9 v down to 3.3volts and then back up again. as such, computer wont boot. power isnt stable @ u7200.
Replaced ISL6295 but no change, Checked Current limiting circuit and resistors/ caps , all check out fine. would love to see if this board is bootable or in the junk heap.
thanks
