Hi, I have an A1466 820-3437-B that has a strange behavier. Sometimews it powers on OK, and other times it dosen't power on. Some times I get green light on the charger, and other times i don't. Sometimes I only get green light with the charger in one position (If fliped the cable) it don´t get green light, but sometimes the mac powers on even so.

Sometimes it boots pushing the power button and other times it only boots connecting the charger.

First it wasen' powering on at all, and the client said that it happend after a fall. I already replaced the SMC, and it started to power on- Then I replaced the battery, but it has the same behavier. It seams to first happend, when it goes out of battery.

Sometimes the battery apears with 100% charge, and afetr a reboot it has 35%, 15, 20...

Can you help?

Possibly broken solders/traces.
Did you test the board alone on the desk (w/ and w/o LIO flex connected)?
When no Magsafe light, do you still have 3V42_G3H and PPBUS_G3H present (not only sometimes)?
