Re: Macbook pro 820-2530 troubleshooting
Im doing it man im watching all of them..
Im just trying to learn dude dont have to be mean.
Well after building again all the paths i have no shorts.

Re: Macbook pro 820-2530 troubleshooting
Is it normal to get 0L on multimeter when measuring resistance to ground (diode mode red on ground, black on path ) when circuit has no power?
I get 2.6 when there's power on that railLeave a comment:

Macbook pro 820-2530 short on PP18V5_G3H
So this system has 17.2v on PP18V5_G3H with 0 resistance to ground.
Removed R6905.
Still shorted
R7062 gets 7v instead of those 17v. Removed and board still shorted.
Fuse on that line is ok..
Any ideas?...Leave a comment:

Macbook pro 820-2530 troubleshooting
So this system is not turning on, no light on charger when plugged in.
I start troubleshooting and i get 0v everywhere.
Replaced r6905, c6990 and c6999 now i have 3.6v and 17.2v on both sides of r6905.
D6905 has 3.6v on pin 1 but 2.7v on pin 5.
Q7050 has 1v everywhere less pin 4 which has 0.22v.
Pin 4 is CHGR_BGATE which comes from U7000.
U7000 has:
0v on DCIN,
4v on ACIN,
0v on VDD,
1.7v on PP3V42 G3H.
U7000 CHGR_DCIN comes from D7010 wich has 0v on DCIN side but 17.22v on... -
