820-2936-B water damage, green light

[Kalemaroni]

Getting 1.6v on CHGR_CSO_N, CHGR_BGATE, CHGR_CSO_P
0v on CHGR_BMON
0v on CHGR_AGATE

Replaced U7000 once and it burnt out and I lost the pad on CHGR_CSO_N so there is a now a jumper from that pin of U7000 to C7050.

 

[Kalemaroni]

17/18 = 334 ohms
27/28 = 34m ohms
R7005 = 22 ohms, 16.5v

 

[larossmann]

after copper wire and replacing R7051 does it work?

 

[aprendiz]

I hope you are not measuring resistance with power applied.... see schematic and tell me if the resistance value of each resistor is right....

 

[dukefawks]

Did you even compare the resistor values to the schematic?

 

[Kalemaroni]

Aprendiz, no power whilst measuring resistance.

Duke, I did compare and then did the following based on that:

I'd already swapped out R7022 and R7021 before I saw your message, and then swapped out R7051. I got an orange light and it was charging for a couple of minutes then all of a sudden the mouse moved very laggy and the orange light went off. ISL6259 is now getting very hot when the power is plugged in. Also, it appears my charger died during all this. I have another though. Any particular readings you want me to take at this point, bearing in mind that ISL6259 is getting very hot very quickly?

 

[dukefawks]

Look at the diagram and tell me why you should indeed measure about 2.2 Ohm across C7050.

 

[Kalemaroni]

Ahhh R7051 is less than the continuity beep! Ok, thanks! Is it ok to use ISL6259A on this board even though the schematic says ISL6259?

 

[larossmann]

ISL6259AHRTZ is what all these boards use from 2010 and upwards.
