Dell LA-G892P Schematic needed
Hi. Does anybody have schematic for this dell laptop motherboard, LA-G892P Rev. 1.0? I see some post regarding LA-G891P but there's a lot of components missing and there is another winbond chip labeled UT2 close to UT6. Thanks -
Update on this card. 5v is now present, I found out that the brand new ic's that I used was fake (bought 10 pieces online that came from China) I acquired another 10 pieces from different store and it worked. Unfortunately after replacing the ic again, pwm controller is heating up. I guess I'm stuck here because I know this pwm controller NCP81022 is programmable and I had no idea how to do it. Searched the net and found nothing relevant to this procedure.Leave a comment:

You can check the temp of both pwm and driver ic during startup (after pressing power button) You need to know if pwm controller goes more than 45c. If it does you need to check around pwm. Or you can check how much current is drawn. I had a board with this issue, after pressing power button pwm soars up to 82c causing it to shutdown right after logo. This is just based on my experience.Leave a comment:

I had almost the same issue like you but on a different card, a 6600xt. I tested all coils and ended up on vddm. I took the risk and injected voltage on the coil. Found out both memory and gpu core is heating up all at the same time. I did not proceed further as I know most of the time it is the core.Leave a comment:

The resistance of the output pins are 9.09 mega ohms.
Another update. Pin20 (BOOT) of U501 has 4.66v. On R624 pin2 is 11.99v but pin1 has 2.7v going to pin6 (TON) of U501. I tried to read the information about this TON pin but I don't fully understand. Based on the site, I should also check the feedback circuitry and found 0v there. Thanks for the reply....Leave a comment:

If bios settings won't save even after replacing bios chip, check RTC line. Usually it is found around cmos battery or close to it. Most of the time is a 3 pin diode.Leave a comment:

MSI RX 5700XT 5v missing
Hello guys I need a little help here. I'm trying to fix this graphics card regarding it's 5v missing. The card came to me with a shorted buck converter GS9230 (U501) with zero output. I replaced the IC with a new exact same model and the short is gone, but still no output. I checked surrounding components and there seems to be nothing else is at fault as to my knowledge.. I removed coil (L500) to isolate furthermore.
Thinking that the new buck converter could be defective, I decided to replace it again with a new one but same result. This buck converter is a standalone IC which outputs... -

Low resistance reading on 3v line, Asus Prime H310M-A R2.0 desktop motherboard
Hello Everyone and Good Day,
I've got an issue with this desktop motherboard. It does not power on, Asus Prime H310M-A R2.0. I tested 33ohms reading on 3v line on the ATX connector. It beeps on continuity mode. I tried injecting voltage from 0.9v at 1.5amps and no current being drawn. I raised the voltage to 3v @ 4amps and now I only get 22mA on current. I checked with thermal camera and there is no part heating up. I'm afraid of going further the safe voltage. What could possibly causing the line to be shorted. 5vsb has no short. I get 0.9v on positive pin of power switch. There's... -
What part specifically did you remove? In my case I removed two mosfets labeled "PQW1 and PQW2" and it worked for me. Although your board layout maybe different....Leave a comment:
