820-4924 power up late

[Alan.L]

the board was liquid damaged, but someone already has cleaned before me. when you plug a MagSafe, the board doesn't start up immediately.
you will have to wait approx 1min then will boot normally and it passes apple dialogistic.

i can't see any corroded components anywhere under a microscope.

crap under the cpu and needs to be reball?

Post the basic power on signals.
Did you reball SMC?

Check RTC signals level...

nope, i havent touch anything. all smc, cpu's all edge bondings are still intact.

thanks, I'll check in a bit.
