Hi all

I've an HP Z200 (full size not SFF) that turns off after exactly 30 minutes. I believe this is a function of ME when 'somethings wrong' with the ME. My aim is to make the motherboard useful again by some means and I'm hoping someone here can assist me.

I've a post on HP forums that has directed me here. There are lots of screen shots of my BIOS and the output of attempted firmware/driver installations. A second Z200 owner is reporting the same issue that I have.

The elephant in the room to me is that Ctrl-P does not bring up the AMT config screens. Note this motherboard (I actually have 2x motherboards and both do the same thing) is an eBay purchase and I have no history until I eventually twigged the shut offs where repeatable at 30 minutes after switch on. It was too late to return the motherboard by the time I had gotten around to building the hardware and installing Windows to it.

I have access to a Raspberry Pi and a Pomona clip on reader and I've had a look at me_cleaner. me_cleaner read the BIOS but cleaning it and reapplying it has not managed to disable the watch dog timer.

My HP forum link showing my progress to date is here

I appreciate any guidance/reading materials or direct help. Please note that this is the first time I've tried to do this and my terminology and understanding is evolving (please be gentle)

Many thanks

Hi

e15 is indeed in the top right hand corner. It's described as Crisis recovery header/jumper in the Z200 manual I've downloaded. The pins aren't actually on this board, just the pads. For some reason, the site rotates the image by 90 degrees when the image is clicked on to enlarge.



I've just back in. Is it still worth me trying to short out the undocumented jumpers or are you thinking about forcing a BIOS recovery?

Thanks for this. You are correct that a password here changes things a bit.

I did add a BIOS password which was required to amend some of the options in the screen below. However, it didn't make a difference with Ctrl-P unfortunately.


I since hacked away and probably made things worse as I've wiped all ME regions in the BIOS via me_cleaner.

What you need to do is download the latest BIOS from HP and flash sp75207 > DOS_Flash > 7H3_0122.bin with the SPI programmer. Your current SPI image has Pre-Production ME firmware which is wrong for your platform as you need Production. This was caused by HP releasing by accident PRE firmware instead of PRD at their "Intel Management Engine Firmware Update and Utilities v6.2.61.3535" downloadable sp81826 softpaq. I had noticed that back in August 2017 and sent them an email explaining their mistake. They responded after a month saying that the problem was fixed. Well, not really apparently.

As I said, use the programmer to manually flash 7H3_0122.bin in order to fix your problem. Same process like you did with me_cleaner but this time using 7H3_0122.bin image.

I said 2 or 3 pin jumpers Thanks for the files, I will get into this tonight for you. Ohh, I see page two now, you've got the support of the best person for ME work, so you're all sorted now once you follow plutomaniacs advices!
And thanks again Plutomaniac, I would have noticed all that too, and updated the ME FW anyway, so it would have been sorted out eventually, but I really appreciate it when you step in since you are the ME genius!!

Keep your backups safe, in case you need to edit and program back in your board specifics after programming in the BIOS above, since they wont be included in the default file when you program it in unless plutomaniac transferred all that over.

Oooo - I have reason to be quietly confident! A new BIOS menu option has appeared called Management Operations with MEDx, Remote Assistance Prompt etc.

I'll leave the PC on and see if it lasts more than 30 minutes and have a play. It threw an error on boot related to serial number. I don't think I need to worry about that. I'll report back in an hour or so.

Yes, you'll need to put back your board specific details later probably (UUID, Serial, and possibly LAN MAC ID)

Ah yes, flash the attached SPI image. For some weird reason, HP has appended another ME region at the end which is not even relevant to the target platform. Removed the junk at the end so now the SPI image is 8MB and proper.

Great it's now working more than 30 minutes @lwoody7110 - I told you it was possible and would be easy!

As for the system details, it's easier for me to just swap out the entire NVRAM volume, and certain padding sections if details are there, which on the paddings is hard to explain if you aren't familiar with UEFITool
LAN MAC is either in the above mentioned sections, or in GbE region. Please zip a backup of both your now current working BIOS freshly dumped, and then an original BIOS dump before any of the edits.
This way I have both files and for sure the ones I want, and don't have to download previous files trying to find out what's what etc. You can upload to a file host, or attach here is there's enough space (you may need to split rar/zips, that's why I suggested file host instead)

Once I have both files, I can either show you how to do once I check them and find locations of data in question, or do it for you, then you reprogram again and then you'll be all done.
