Hi guys,

Got 820-3476 and when i plug magsafe there is no light. After aprox 1 minute light appears green, than orange and macbook turn on and works as normal.

Some caps? Any advice?

Try fake charger, or lab supply too; any change?
Does it charge the battery, starts with battery only?
Run ASD EFI, see if reports any error.
Also try to start in SMC bypass mode.

Check 3V42 and PPBUS_G3H, and SMC_BC_ACOK in that minute..
