How about giving Windows 10 a try (or maybe even a Linux distro) to rule out any weird OS related incompatibility issues?... -
Nobody got any experience dropping a Bios from a working motherboard into another one?
Are there any secondary checks with the existing hardware involved?
How would I go about this, dump the Bios from the working one, clean the ME region, and flash it onto the non-working board?...Leave a comment:

Nope, that's not the problem either. My other Zbook 17 also has 2.4 on this line.
Can I just dump the Bios from the working one, and also drop it into the other, and it'll work,
or is that not advisable? Could someone repair my original dump, ME region cleaning alone does not fix it....Leave a comment:

My problem does not seem to be bios or ME region related after all. After flashing a few main Bios and EC bios versions,
I checked the power button and the zif socket for the powerboard flat ribbon cable (with the PB disconnected), and I only have 2.5V on that 3.3V line.
Nevertheless, the laptop always powers on, but with the symptoms described above.
I do have stable 3.3V on the Bios chip,so 3.3V must be healthy in general, but something seems to drag it down on the PB line.
That's going to be fun, hunting for this stupid fault 😒Leave a comment:

The good news: after flashing the cleaned bios (I took yours, you are the pro :-)) the laptop still turns on.
The bad news: the behaviour is exactly the same, nothing has changed. What's next? On to the EC bios? Where do I get a clean copy?
Can I take any version from this forum for 17 G1?Leave a comment:

Thanks man, I just used Intel ME System Tools v9.1 and 9.0.22.1467_5MB_PRD_RGN.bin prior to seeing your post, and it worked for me as well.
But we got different checksums on our outimages. Is that a cause for worry?...Leave a comment:

Well, now at least I get a different error after replacing ME Region.bin in folder Decomp, opening the untitled.xml and trying to build the image...Leave a comment:

Ok, I see, I am definitely a moron. I didn't realize I need Flash Image Tool version for V9.0.
I'll try to get this done myselfLeave a comment:

Need help cleaning ME region on Zbook 17 G1 bios dump
Hello guys,
could I please get some help cleaning the ME region of the attached Zbook 17 G1 bios dump (CH341a, neoprogrammer, chip-desoldered, dumped twice, identical checksum)?
Symptoms, delayed BIOS post (ca. 45 secs.) keyboard not working, touchpad not working, booting linux live, console says "Management engine not configured".
I tried following the ME firmware cleaning guide, but whatever Flash Image Tool version I try, I get the same error:
[COLOR=#ff0000]Error 10: Failed to open with processed commands. [/COLOR]
[COLOR=#ff0000]Unable... -
I resurrected an HP 8570w with a corrupted BIOS just a few days ago which had failed to come out of standby.
Device came on, no boot logo, fan ramping up, no sceen output, 5 blinks on caps lock and amber lights on wifi and volume button.
All voltages checked okay, Bios recovery did not work, so I desoldered the chip and flashed a known good one with a programmer. UEFI BIOSes are weird sometimes,
especially HP... :-)Leave a comment:

Never owned one myself, but Amilo Xa 3530 was notorious for for premature gpu death back in the days.
If you offered me to bet, my money would be on the graphics chip.Leave a comment:

Hi,
check here, maybe this gives you a lead:

Maybe you have a similar case with a defective temperature signal mosfet on the smbus lines to PCH...https://Hi,<br /> <br /> check here,...onnected[/url]Leave a comment:

Re: Hp omen 15 nvidia gpu problem?
I'd suggest downclocking vram with msi afterburner or a similar tool to check
whether it is stable on let's say half clock rate. If it is, then slowly feel your way up to where it becomes unstable again. Failing/semi-defective vram is very often no longer capable of doing full clocks, but runs okay on reduced speed. Then you could flash the stable clocks to vbios.Leave a comment:

Re: HP Pavilion 15-cs1042ng - unknown 3.3/5.0V LDO
Tbh, there's not much else coming up aside from this one CPU phase. All other coils
around the GPU, the CPU and the RAM are without any voltage.
The last thing I could feasibly try now is probably reflash the Bios with a version found in this forum.Leave a comment:

Re: HP Pavilion 15-cs1042ng - unknown 3.3/5.0V LDO
I've reassembled the laptop, but it won't POST. It's looping every five seconds or so,
no reaction to capslock. I see 1.09V coming up on one CPU phase, but no voltage on the Ram. Nothing getting warm, just looping.Leave a comment:

Quite a coincidence, the whole thing went remarkably like this one here:

Re: HP Pavilion 15-cs1042ng - unknown 3.3/5.0V LDO
I just can't believe it. I injected some more, this time 2V at 0.4A current draw and the short cleared itself
You literally could see it fizzle out on the bench power supply, slowly going down.
I now have the white light on the charging port
Weird case. Will reassemble the thing tomorrow and give an update.
Edit: battery is also charging. Hopefully no further damageLast edited by loopster; 03-12-2023, 05:04 PM.Leave a comment:

Zilch on the left pad, 0.36A on the right. Resistance to ground on the left in the Megohms,
on the right I get nonsensical readings depending on the measurement range I choose. Took two different multimeters. From 60Ohms up to 5k? I am currently recharging the batteries for both to see whether they read bullshit due to low charge...Leave a comment:
