So for the boot sequence everything looks good until I hit PMU_PVDDMAIN_EN which is low, after that P3V3MAIN_PGOOD is low.
I don't know if there is anything else to investigate based off of that.
Also the Board View File doesn't appear to have H9M_24MHz_Clock although I imagine I can check other 24MHz lines?
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Oh no I have have already purchased it with great zest and gusto. I just didn't know about that feature, so now I must investigate it....

Ohh wonderful. I was trying to figure out if there was power sequence data. I'm confused are the openboarddata files separate from the board view and pdf, or normally included in the board view?...

I will have to check out gsmartcontrol.
I definitely prefer checking drives in linux, since it doesn't have the bad habit of trying to handshake and index a bad drive like windows....

LG Gram 17Z90Q identify component labeled BACDSG
Trying to identify this part if anybody has any idea what it might be, would be a good start to repairing this laptop....

I tried checking DFU with just the USB connectors mounted to the board, nothing showed up on the apple configurator on my 2015 mbp.
PP1V8_SLPS2RSW_DFR isn't present. The sequence says only PP1V8_SLPS2RSW but my board view only finds with _DFR....

Thanks for that recovery tool that allowed me to install.
So Dell isn't locking out 3rd party drives, just making it more difficult. Another issue is the factory reset the Dell Service rep told us to use disabled the NVME slots, so we spun our wheels for a little bit after that.
Dell service does have a problem however. They actually lied to us and told us this [url]https://www.dell.com/support/home/en-au/drivers/osiso/recoverytool/w2021[/url] didn't exist even though we asked specifically for their recovery installer.
He also told us that there were only specific...

Right that's what I'm trying to avoid. I know the Apple Configurator will show a giant DFU if it's in DFU mode, can I check with bare board no battery?...

Evaluating Mechanical Hard Drives SMART Data in Linux (Ubuntu) Using the Disks Utility.
I've gotten into the habit of Looking at peoples Mechanical Hard drives with a Ubuntu thumb drive to boot their system.
I understand the raw values are not really uniform between manufacturers, but I have noticed that high seek and read error raw values at the very least correlate to a drive that is going to have sub par access time, and extremely slow OS booting.
The odd thing is I've often seen very high seek and read error rates on drives with fairly low on time.
Does anybody have any other takes on evaluating smart data? I've used Crystal Disk Info, It seems to present...

I'll see if it's DFU now. Can one DFU just the board safely without fans out of the case?...

I stole the CD3215 Chips from another A1990 so we should be gucci unless they are incompatible between the same models?

I will try that. We can't see the drives in the BIOS either....

A1990 820-01041 5V .4A Troubleshoot
I have the above mentioned MBP, quick scan with thermal camera revealed that only U3200 was heating up. I found that C3208, C3219 and C3205 were all reading ~6.8ohms to ground.
so I swapped U3200.
I connected the PSU again for a quick check on thermal it's drawing about the same amount of current but now I'm seeing only heat radiating from U7800 and the T2 chip from under the black shielding fabric, and the bottom of the board.
It's hard to judge the actual temperature without removing the shielding.
Does anybody have any insights?
PPBUS_G3H is...

It's a 2022 I don't think you can even buy it with Windows 10 if you wanted to.
We have disabled all of the security features on the board but it boots up saying secure with Dell Safe Bios or some thing like that.
I followed other peoples tutorials on how to extract the intel highspeed storage drivers from the Dell install packs using 7zip, and loading drivers from a second USB drive during win11 install.
It doesn't work at least not on the 2022 XPS 9520.
After a long conversation with the Dell Service Rep they said even their Dell Hard drives...

DELL XPS 9520 No 3rd party SSDs?
So we have a DELL XPS 9520 a woman broke her screen and needed an immediate replacement so we removed bitlocker and put her Drive in an Asus TUF gaming laptop, everything is hunky dory.
We happen to have another DELL XPS 9500 screen that is compatible with the 9520, so tried installing new SSD's and doing a clean windows 11 install.
During formatting the installer can't find the Intel drivers for the nvme controller?
I spend a long time figuring out how to extract the drivers from the official dell installer downloads tried different versions, was able to load the drivers...
