820-4942 draws 500 mah

[Ken]

I have a 820-4942 pulls 500 mah, no liquid just shut off on customer.
Has 3.3 on all sys power good and cpu getting warm. New to this board what do you guys need to help with this one?

 

[2informaticos]

So board turns on.
Did you check external video and USB activity?

PLT_RESET_L goes high?

 

[Ken]

I did not, will in the am

 

[Ken]

Update reassembled and mac now beeps 3 times

 

[2informaticos]

Puff, RAM error; which can also be caused by CPU.
You should reball all RAM chips, are not too many on this board.

 

[Ken]

I reflowwed them and it booted. So will pull and reball.

 

[Ken]

Reball complete. Testing now no beeps and fast..
Is this issue common?

 

[2informaticos]

Not so common for this board...
