Intel ME has to be deactivated and most partitions removed use ME_Cleaner its working. i have used it on my Dell Latitude 14 Rugged (6th gen) and on my alienware 17 R4 (7th gen) also it was wirking on my friends New Alienware 17 R5 (8th gen) Use SPI flasher to dump the flash than give it to me cleaner xxx.bin -s -S save.bin option you need linux, or either Phyton 2.7.12 for windows to work, dont go higher version of python it will generate errors i spent hours to troubleshoot.

By the way i forgot to mention if your bios and system are manufactured after 2015 just go to dell downloads then get the bios.exe file than rename it to [ BIOS_IMG.rcv ] than format a 2gb USB drive to fat32 and copy the bios recovery onto it. turn the computer off wait 5 sec, than plug in the usb drive and continously press CTRL+ESC while you press the power button the bios recovery should load now and just fallow it through.

To recover full bios functionality you need to follow new crisis recovery procedure for the (after 2015) workstations or pc's identical, laptops somewhat different.
1, download the bios_xxx.exe from dell for the service tag in question.
2, format a relatively small 2-8GB USB flashdrive to (FAT32).
3, rename BIOS_xxx.exe to [ BIOS_IMG.rcv ] than copy it to the USB flashdrive.
4, power off the computer, and insert the USB.
5, hold CTRL+ESC while pressing the power button, but keep hold CTRL+ESC until you see the bios recovery
Follow instructions, this method actually will overwrite the whole content of the flash including intel ME region that the normal update actually have no permission to do. Intel say is for security reasons, they disabled reading and writing in the security descriptor. I would say if you not planning to use ME as a remote configuration platform is better be removed (crippled) with ME_Cleaner. (for security reasons). ME is basically a small 486 cpu running a MINIX os intels (Active Management Technology) from the beginning on kernel ring level -1 at the first nanosecond as soon you press the power button. It looks a lots of users dont understand or cannot be bothered to do the research, that why the heck we need a computer running below kernel level waaaaaay before my bios actually loaded into the memory. Basically without intel ME your CPU will shut down every 30 minutes or so. I have tried it. Only way to access intel ME module in the SPI flash is either use the fatory recovery tools provided i,e Emergency bios recovery or with an external flash programmer.

Can I use your procedur to recover my dead Dell T5600? My dell got bricked, no caps lock or hum lock on the keyboard. When I turn on the system immediately led 3 and 4 flashing with amber power light. I'm sure the bios got currupted.

I have MINIPro Programmer. Can some one sent me bios bin for 8MB and 4MB bios? I really need this computer to finish my work. Thank you so much

Thx sorry for my bad englist

Since you have programmer, get a verfified dump from each BIOS chip before you write anything. Upload them here and then I can pull your details out and put in other dumps for you to fix the board with (Serial, LAN ID Etc)
If you want to do yourself, there is dumps linked in this thread, and another link in there to with another thread that has dumps in it as well - DELL T5600 - BIOS A15 & A17

Ah ok thankyou so much i will upload my bios ti zippy share.

here's my bios dump.

https://www101.zippyshare.com/v/YiBSVHe4/file.html

What happened to cause brick, bad BIOS flash, bad mod BIOS, or bad ME update etc? So I can know what might need fixed.

This info I found so far, can you please check system stickers and see which of the bold is the exact system model/ID, thanks

I didn’t do anything... just plug the ac cord and diagnotic led number 3 & 4 imideatly flashing. I measure ram and cpu voltage using multi meter, volatge reading is Zero.

So i assume that the CPU doesnt not POST. It’s just my assumption

OK, well lets do quick dirty test without getting your board details in BIOS first, except I will correct LAN MAC ID so your Ethernet works. Then if working, we know CPU is OK, and we can then fix BIOS with board details I asked about.
Here is dump from another users board, working, with your LAN MAC added. Please test if these are working, if it's working then we'll move forward and fix your board details.

From these three links, it looks like 3+4 means system is in sleep mode?

Also, if you moved memory during troubleshooting, check this, you need at least one memory stick per CPU following the guidelines

Im not in home right now.,,, in few more hours Soon as i get home i will Flash your bios.

From the link you give me, i only see Solid Led 3-4 not blinking led 3-4.

Again Thankyou gor your help

You're welcome! Yes, sorry I was not sure how that would look and what LED's you meant etc. Read each of those links, none apply?
Hopefully BIOS in #25 is working for you, otherwise you may need another CPU to verify if CPU dead, or another board to test your current CPU in

Ok i’m home and ready to flashing the bios chip. I give you the result in 39 minutes.

About the Led. What i mean is Front panel diagnotic LED.

Sorry for late. Just want to tell you that bios is ok. Unfortunately the problem is in my Cpu, Both my cpu shorted to ground.

I try using another processor the cpu boot fine.

Thx for your help.

Glad your board and BIOS is OK, sorry about the CPU hopefully it can be replaced with cheaper one now than when new. How did CPU short?
