820-00165 no ssd detected. wifi works, it chimes, usb mouse powers up, fan does not cycle. im getting voltage to the ssd coil. main rails appear to be ok.
History, Liquid damaged but was ultrasonicly cleaned by previous tech. C1053 Pin2 GND was corroded so i ran jumper to C1043 Pin2 GND.
U5800 has been messed with but dont think this has any affect, i could be wrong. U6100 looks like its been reflowed as it has hallmarks of a tech who uses no flux, it seems okay. ISL6259 has had its R7121/2 resistors replaced. and Fuckme the smc silicone is gone! LP8550 has obviously been changed too. all in all this system looks pretty healthy. no burnt points. Oh JTAG is missing.
any assistance on where to start would be great. ill start measuring the rails again.
