I don't think reprogramming the BIOS chips is going to do very much since it POSTed just fine. Your BIOS chip is the one in the 3rd image (the WinBond chip below the VENDOR: TRIPOD text).
Proceed at your own risk however. Did you try reseating the memory at all? What about swapping the memory?

Re: Vostro 3510 LA-L246p missing 3.3V and 5V
Do you get a charging light?
Disconnect all power. Check the resistance to ground on the 3.3V coil, the 5v coil, 1.8v coil, and Pin #8 of the BIOS chip.
Also, check resistance to ground at the input current sense resistor.Last edited by ResoluteHawk; 10-02-2023, 12:02 PM.

Re: Dell Inspiron 3520 PW Removal
Please disregard. I figured it out using information from Post #48 in this thread: [url]https://www.badcaps.net/forum/showthread.php?t=87872&page=3[/url]Re: Dell Inspiron 3520 PW Removal<br...2&page=3[/url]

Dell Inspiron 3520 PW Removal
I need to have a password removed from a Dell Inspiron 3520.
I'd also like to know how this process is done because I cannot find any information on where the BIOS password header starts and ends, and I'd like to be able to remove the BIOS password without completely erasing the IC and rewriting it.
Thanks....

Re: ASUS g731 fan control not working
Typically, if an EC/SIO chip is BGA, it will receive its programming from the BIOS chip.
Just make sure that you order a blank chip.

Re: ASUS G14 GA401QM No CPU Fan RPM
I may have found the culprit of the problem.
There is a straight short between two of the pins on the fan connector for the CPU, specifically the 12VS_5VS_FAN0 (Pin #4) and FAN0_PWM (Pin #3). The CPU fan connector itself looks perfect. The pins are all aligned properly and the inside of the connector is not damaged either.
I checked the continuity between those same two pins on a known working G14. The same 2.0V drop is present.
What could cause this short to happen if the fan connector is not damaged...Last edited by ResoluteHawk; 09-15-2023, 05:07 PM.

Re: ASUS g731 fan control not working
So I have this exact same issue on a G14 and I saw this post and went to measure those two lines. Straight short between both of them. Interesting.
About 10 minutes later I measured it again and there is no short. Back to the drawing board....Last edited by ResoluteHawk; 09-15-2023, 04:44 PM.

Re: ASUS g731 fan control not working
Please reply to this post if you find a fix for this.
I have the exact same issue with a G14. I think the issue might be related to the EC/SIO FAN TACH pin but I'm not 100% sure.

Re: Eluktronics Max 17 1st gen rtx 2070 resistor pcb repair
Going from your second image in post #1.
On the bottom of the image are chips (from left to right): A1, A0, B1
Chips on the right side of the image (bottom to top): B0, C1, C0
Chips on the top side of the image (right to left): D1, D0
You've found with the MATS test that you have two bad banks, so I'd go ahead and remove them and replace them, then see if you have any changes.
Make sure to measure the GPU memory resistance after replacing each of the defective c...Last edited by ResoluteHawk; 09-07-2023, 10:19 AM.

Re: MSI MS-17F51 Chip
PU5 looks like your 3.3v/5v buck converter.
Speaking from experience here; if this chip heats up when power is plugged in, it usually means that your Super IO chip (U22) is fried.
Just because PU5 heats up does NOT mean that the chip is bad. To verify that your 3.3v/5v buck converter is good, make sure that the input voltage is good (19-20v) on PC59, and make sure that the chip is producing the correct voltages (3.3v and 5v). Check PC65 for 3.3v and PC60 for 5v.
Check for shorts on the capacitors around U22 (C928, C929,...Last edited by ResoluteHawk; 09-06-2023, 09:50 AM.

Re: MSI MS-17F51 Chip
Your BIOS chip is U37. It's located above and to the right of the PCH/Chipset (the big chip on the left side of your photo).
If the chip in the first photo is the same chip as the chip in the 2nd photo, it looks to be a USB load switch.
What problem are you running into exactly? Is the system not powering on? Not posting? USB ports not working?
If that chip is burned I would take it off to start with.Last edited by ResoluteHawk; 09-06-2023, 08:32 AM.

Re: MSI GS76 STEALTH 11UG No Power (Please tell me I didn't kill my baby!)
So does the laptop turn on when you press the power button with the battery connected?
1) Yes and No. Your Super IO could be partially shorted and still perform basic functionalities.
2) The main possibilities for 0V on the CPU inductors are:
=> a) laptop is not powered on, hence no CPU voltage
=> b) a straight 0 Ohm short to ground on the CPU inductors
=> c) the CPU PWM driver that opens the cpu mosfets isn't working correctly, even when the laptop...Last edited by ResoluteHawk; 09-01-2023, 05:15 AM.

Re: ASUS GA401QM No POST (RAM issue?)
Hmm. I didn't find that chip but I did measure those two signals in diode mode before and neither signal is shorted to ground.
Yeah....seems like this one is indeed a rabbit hole.
So why put PCH signals in the schematic if this is an AMD board and there is no PCH?Last edited by ResoluteHawk; 08-23-2023, 01:37 AM.

Re: ASUS GA401QM No POST (RAM issue?)
Yes both signals have voltage present.
APU_PWRGD is 1.8V
CORE_PWRGD is 3.342V

Re: ASUS GA401QM No POST (RAM issue?)
Ok so I'm still a little hairy on where the remainder of these signals are located.
I found DRAMRST# on Pin 108 of the SODIMM slot. No voltage on it.
No voltage on PLTRST# at R0704.
The only point I can find for PM_PWROK_PCH is GC6FBEN_PCH. No voltage.
I did look at APU_PWRGD and APU_RST# and those are both 1.8V.
SYSRESET# is 3.362V.
So the signals seem to stop at PM_PWROK_PCH if I measured correctly.
This was a laptop that I purchased to repair and I can still return it. When I...Last edited by ResoluteHawk; 08-22-2023, 10:11 PM.

Re: ASUS GA401QM No POST (RAM issue?)
Memory voltage is present. We're not missing VMEM unless I'm not understanding you. I don't know where to check for DRAMRST#.
The problem is that we have 1.2V on both PL9401 and PL9402. The GPU memory is not being pulled High like it states in the schematic. It's staying Low at 1.2V. I'll have to check the resistors for MEM_VDD_CTL.
CPU is receiving voltage but it's supposed to be higher before being able to POST (+VCCGT needs to be present for integrated graphics, or for a display in this case). This is why I'm measuring...Last edited by ResoluteHawk; 08-22-2023, 07:54 AM.
