Re: A2289 Board 820-01987-A Dead?
Hey dbteckos. Sorry for the late answer since then I have bought another 820-01987 board and here with no signs of corrosion or other damage but it takes 200mA and 20V dont know why yet.. the old board are stock on DFU mode now and it only takes 80-96mA 20V
I measured the testpoint (beside J8401) for both board diode mode = Old board : 1.788 new board : 1.700
Here are some other measurements for old and new board
Ny board
L7270 = 14.30 ohm
L7210 = 4.30 ohm
L7220 = 4.30 ohm...

Re: A2289 Board 820-01987-A Dead?
Hey dbteckos did you managed to solve it? i have almost the same issue cuz of water damage..mine is using 20V and 500mA with the TrackPad and 20V with 60mA without it. the fan spins, CPU is warm but no image on the LCD. The U7420(FDMF5804,SIC621) is blown will that effect the image?
