Lenovo ThinkStation P720 BIOS Request

[HammyCheesy]

Hello all,

I'm trying desperately to revive a ThinkStation P720 that I purchased from a seller who claims it suffered a "failed firmware update."

When given power, the machine turns on, spins up fans, beeps a single time, fans slow down, then a beep code is sounded repeatedly (3 high/short tones, 1 low/long tone).

Type: 30BB
Model Number: S03600
S/N: MJ07N68C

Things I have tried:

1. Reseated all components, pulled everything except for 2 RAM modules (1 per CPU)
2. Attempted to boot with just a single CPU and RAM module
3. Set CMOS/Recovery jumper and attempted to boot with recovery media as outlined in Lenovo HW Maintenance Manual
4. Removed CMOS battery, dumped firmware from 25Q256JVFQ BIOS flash chip
- Re-flashed with cleaned ME region image (built with Intel FIT)
- Re-flashed with fresh Lenovo BIOS region from Lenovo support website (extracted with BIOSUtilities)
- Re-flashed with both cleaned ME and fresh BIOS region
- Re-flashed with bios provided from this post
- Re-flashed with image processed by me_cleaner
5. Dumped firmware from W25X40CL "SIO" Super I/O Flash Chip
- Re-flashed with SIO firmware update from Lenovo support website
6. Jumped un-populated "ME_DIS" pads found on board

All of these steps resulted in the same failure (3 high/short tones, 1 low/long tone) - although somewhere along the way, when given power, the system started power cycling once before emitting the tones (power on w/ fans, quick beep, power off, power on w/ fans, repeated error beeps).

Also, when I flashed the image processed by me_cleaner, the system did not turn on at all - no fans, no error tones, nothing.

I'm attaching my original, unmodified dump of the BIOS chip if it's of any help.

Any guidance would be very greatly appreciated!

Thank you!

I couldn't find a way to edit my post, so I apologize for the spam, but my motherboard is 01LM603.

Thank you for your help!

I flashed the binary you uploaded and now the system almost immediately shuts down after power on without emitting any beeps.

I'm going to try patching the BIOS region of your image onto my original image to see if that helps at all - but I'm appreciative of any help or pointers.
