No it is not getting hot when I had the charger plugged in.
When I removed charger and injected voltage on Pin 1 of C7505, U7501 got really hot at 5v and even around 3v.
Okay I injected 5v and I got 1.09amp draw and u7501 got very hot again.
Do you think it is the chip again or something else causing it do that? The end of the capacitor on C7505 came off after I took the wire off of it after injecting voltage so I'm going to need to replace that as well.
Resistance to ground on 5v_s5 is around 1.7MegaOhms. Diode Mode shows 0.44v
Trace is good on Pin 23 of U7501.
3.31v on Pin 22 of U7501
I did feel u7501 getting slightly warm so I replaced it and still I get the same measurements as before.
Yes PP5v_S5 is the one thats 1.7v
I cleaned the board a few days ago but I don't believe there was corrosion around the u7501 chip and all the probe points look pretty good around it.
U7501 voltages
Pin 4: 0v
Pin 12: 3.43v
Pin 21: 3.43v
Pin 23: 8.59v
Okay I checked again this morning and there was no short. I'm thinking all the heat on the board was messing up my measurements.
Anyways, now I get 8.59v on ppbus but I am not getting voltages on other rails.
PP5v_s5 pulses initially at 5v then just stays at 1.71v. I have 0v and no pulses on...
In diode mode with L7130 on the board I am getting 0.004 to ground. With it removed the diode mode readings are normal. Before tracking down and fixing the short previously I was getting 0v to ground on Pin 2 of L7130.
Now its normal and the short only appears when I put L7130 on the board.
I...
I have this 820-3437 Board that had liquid damage around the 3v42 area and some other areas around the cpu by the fan connector.
I replaced all the components in those areas and I get a light on the charger now but for some reason PPBUS_G3H was only around 3v. I ended up realizing that g3h was...
I found this code that allowed me to read and copy the files from my linux computer.

This code worked for me.
bindfs is the answer. It will take an already mounted file system and provide a view of it with whichever uid you'd like:
- sudo...
I'm not sure why they didn't take it to apple. Does apple do things like this if you bring it to them?
So do you know of any way to change the permissions on linux so that the folders with the information can be accessed. I can access the Applications + Utilites on the backup drive from Linux...
Yes I tried that as well but it just stays on that screen that says 'Searching for Time Machine Backups' and the drive never appears on there.
I tried manually mounting the drive using the terminal but it never mounts. The only thing that mounts on the drive is the EFI partition.
Could this...
Okay I followed your instructions for reinstalling OSX but when I get to the Installation Window page the usb drive doesn't show up on that page as you can see from the image attached. I was able to see the drive on the 'Disk Utility' page but only after a few minutes of the drive being plugged...
Okay thanks I will make a clone of this now.
I still don't quite know what 'installation window' you are referring to though. The flash drive doesn't show up anywhere in the Mac except when I hold the option key on startup.
When I go to the "Disks" page in Ubunutu and try to Create a Disk Image of the Partition I get this error.
"Error opening file '/media/mnm/LexarNew/Disk Image of sdc2 (2017-11-05 2155).img': Read-only file system (g-io-error-quark, 21)"
Do you know a better way I can make a clone of this even...
