Hi guys,
Got an 820-00840 that I got for new screen (usual flexgate problem)
Noticed that machine has a 'cold boot' issue where it randomly powers off or restarts during use, especially when cold booting. First few times it struggles to even get to login screen.
After a warm up period is seems far less frequent.
Having opened her up, noticed a very small amout of corrosion around U7370 and L8030 / Q8030.
Have flux and boiled these 2 spots, but now board is stuck at 20v 0.03A. Trackpad clicks when plugged in but CPU does not get warm.
I have checked and have no VCORE voltage present at L7210/20.
From reading other threads I have noticed that L8060 and L7900 seem to have lower than expected resistance in diode mode (0.036v and 0.086v)
Any suggestions?
