Hi all,
I have here gaming laptop asus ROG with motherboard problem. Only orange LED is on, battery charging. 3.3V is on power button and on bios chip. 5V also present. All resistances on coils looks fine instead of GPU coils, only 0.5-0.6Ohms to ground. I don't know if gpu is dead. Can samoone help me to diagnose this problem? Thanks.
Have someone schematic/boardview for this board?

Good Afternoon,
This is my first post here so I apologize if I miss something.
I'm working on an A1708 that draws 20v and 0a with the board removed.
When installed in the machine, it takes 20v and 0.1a. The fan spins up and the trackpad clicks.
Some measurements:
PPBUS_G3H: 13.13v
PP3V3_S5: 3.3v
PP5V_S4: 5.1v
PP3V3_S0: 0.6v
Any help would be appreciated. Let me know if more measurements would help.
Thanks in advance

Hi friends,
I have a macbook pro A1706 820-00923-A that won't start no signs of life, no liquid, checking the voltages I found PP3V3_S5 was shorted, I removed all the processor coils, but when I 'injects a voltage it is the processor which reacts, can you confirm to me that this is definitely coming from there please?
I have 20V on the usb-c connector, and 13v stable on ppbus_g3h.
I saw that a track had burned out on PPVIN_2V7NAND_LB after resistor R9350
I injected voltage on L7660 pin 1 in short but only the processor reacts
Thanks for your...05-18-2024, 12:33 PM -

Hello. I have problem with Dell psu, outputs are ok but it does not give power ok signal.
It has a secondady board with wt7527s to check inputs. It doesn't give PGO because it doesn't take enough PGI.
It takes PGI from a voltage divider.
I draw a schematic for you to understand.
My first question is why 5v use two transformer pins, while 12v uses only one.
My second question, is pin 2 in transformer weak? After resistor, diode and voltage divider, result is 0.7v instead of 1.2v, so wt7527s does not output PGO....Today, 07:33 AM

The unit had a battery replacement , it used to work with a 2200 mah battery that i have found swollen, i have replaced it with a 1500 mah battery( i couldn't find one available at 2200mAh), tested working, after 2 months of beeing used in the car always plugged to the charger the owner sayed that it's not charging, the battery had 3.3 v instead of 3.7 , i have installed a new battery of 1500mAh, the unit powers on , shows 1% battery and it only draws current when the display is on and only shows the charging icon when i first plug the cable in then it stops after 10 or 20 seconds,and if i turn...Today, 06:18 AM
