    PPBUS_G3H Shorted to ground with coil put on

    Pin 13(VREF2) is at 1.99v Pin 22(VREG3) is at 3.32v There is no short on L7520 or L7560 either.

    PPBUS_G3H Shorted to ground with coil put on

    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.

    PPBUS_G3H Shorted to ground with coil put on

    I replaced u7501 and C7505 and still I only get 1.72v on Pin 1 of C7505. I am getting 8.58v on Pin 23 and 3.42v on pin 12 of u7501.

    PPBUS_G3H Shorted to ground with coil put on

    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.

    PPBUS_G3H Shorted to ground with coil put on

    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.

    PPBUS_G3H Shorted to ground with coil put on

    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

    PPBUS_G3H Shorted to ground with coil put on

    No pulse on ALL_SYS_PWRGD. PP5v_S5 isn't pulsing at 5v anymore and instead it just shows a steady 1.7v. PPVRTC_G3H is 3.3v

    No Cpu vcore is not pulsing.

    PPBUS_G3H Shorted to ground with coil put on

    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...

    PPBUS_G3H Shorted to ground with coil put 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...

    PPBUS_G3H Shorted to ground with coil put on

    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...

    Recovering data from USB with Macbook backup files on it

    I found this code that allowed me to read and copy the files from my linux computer. https://superuser.com/questions/3872...lumes-in-linux 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...

    Recovering data from USB with Macbook backup files on it

    smiba Is there anything I can do to change the permissions of the drive?

    Recovering data from USB with Macbook backup files on it

    Yes I have a copy of this drive. Also, the partition with the backup files on it mounts in linux so I'm not sure why it doesn't in Mac.

    Recovering data from USB with Macbook backup files on it

    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...

    Recovering data from USB with Macbook backup files on it

    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...

    Recovering data from USB with Macbook backup files on it

    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...

    Recovering data from USB with Macbook backup files on it

    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.

    Recovering data from USB with Macbook backup files on it

    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...
