General Motherboard Repair Diagnostics Inquiry
When all voltages are present on a motherboard and all are stable with very little ripple what can cause the board to not boot? It behaves as if the processor is not installed and I know that the ZIF is clean and the pins are intact completely. Ive replaced the PCH (Intel-based board), replaced ZIF, every controller type component (VCORE, SIO, TPM, etc) and even reflowed the board but no dice. I would imagine there's a reason like a bad resistor or timing issue, but how do I narrow it down even further? With respect to the Intel architecture preferably for standardization's sake -

Typically for similar symptoms on Dell motherboards, there's an auxiliary power rail that's not present like DDR_Vtt on DIMMs. Reflashing BIOS would be the easiest start but typically those beep codes are pretty accurate -

Re: Dell optiplex 9020 pc dead condition
Typically it's a bad SIO that causes that issue...Leave a comment:

Hey guys,
Still no luck with the board with that problem, but I did find the answer to the question I asked about CPUPWRGD, so I figured I'd share with you guys. It's on the attached PNG
Thanks nonetheless!...Leave a comment:

Pic attached is part. Use search engine to find part number: TPS22966DPUR
I attached circuit picture too...Leave a comment:

Re: General Intel Chipset/Dell Design inquiry
I have a new SPI chip installed and a factory .BIN image installed. I cleaned the image using the steps from the ME clean thread, and I've used this clean image to flash every board that has a corrupt BIOS without issues. It seems to be board specific....Last edited by lustre; 03-24-2023, 04:23 AM.Leave a comment:

Do you need a schematic so you can identify the part on the board? I can get you a link to the proper part tomorrowLeave a comment:

General Intel Chipset/Dell Design inquiry Optiplex 7050 Micro
Hello,
For reference, I am using the schematics of a Dell Optiplex 7050 Micro, D24M8, and will include them in the post if I can (I am a new member, so I'm not quite certain if it's against the rules or possible atm).
My question, what are the prerequisites for the PCH to output CPUPWRGD? I have a board that won't assert the signal, even though I have all prerequisite signals listed on the power sequence map, and I have confirmed all crystals are oscillating at proper frequencies as stated on the CLK diagram. The PCH has been replaced, and a known good SPI is flashed and... -

I hope this doesn't come off as condescending or haughty; I am kinda nervous about the first time asking this kind of question online lolLeave a comment:

Re: New Members - please post your introductions here
Hello everyone, I do Dell motherboard repair and I have a decent amount of knowledge on them. I came here looking for more knowledge and I've been lurking for years but now it's time to give backLeave a comment:
