It's still 7770.

I think your motherboard is actually a 7670; the information is probably stored in the I/O, and flashing any BIOS will only show it as a 7770.

Hi, try writing only the 32MB chip

Dell Precision 7670 and 7770
System BIOS (SKU 0B2A, 0B2B) Version : 1.36.0

It's still 7770.

Hello... This BIOS works well; I previously replaced the I/O chip and successfully saved the service tag... however, the machine displays as a Precision 7770, whereas the actual unit and the tag indicate it is a 7670... I wonder if this can be fixed?

The situation remains the same.

Oh, I didn't know that. I've re-downloaded both files. Please fix this for me or create a new, clean BIOS. Thanks.

The service tag is in the 16MB bios chip , he posted only the 32MB backup.

Thanks for the info.
I had cases when incorrect or partial patch makes this kind of issue.

Try with a new chip...I have no other idea...

This BIOS update didn't work... after entering the tag, saving, and accepting the changes, the tag disappears again.

Hi all,

Just a quick update — this request is no longer актуal.

I had to return the machine to the owner, so I can’t continue troubleshooting on it.

Thanks to everyone who took a look.

Hi all,

Got this Dell Precision 7670 on the bench:

Board: HDC50 LA-L882P Rev 1.0
S/N: 25TVSQ3

Symptom:
When plugging in the charger, the LED flashes once and then goes off. No power, no POST.

What I checked so far:

• Board inspected under microscope, no visible damage
• No schematic available for this board
• No shorts found on main rails
• 3.3V and 5V rails are present
• On plug-in, 5V comes up briefly, but drops when the board attempts to start

There’s a chance it was interrupted during a BIOS update, but I can’t confirm that.

Could someone please take a look at the BIOS dump(s) and fix/rebuild if needed?

BIOS files attached below.

Thanks in advance 👍

Hi, please Help me .. this bios no display, fan running

DELL PRECISION 7670 was working fin was turn on with a BIOS password, but after backing up the BIOS BIN to remove the password, the laptop not turns on; neither no display, no fan running.
Just the power button with a white LED and it turns off after 40 seconds.

I flashed the original BIOS, but still doesn't work.
no display, no fan running.
Just the power button with a white LED, and it turns off after 40 seconds.

ST# number does not appear on the case; it has been erased or removed, or the case cover has been changed.

Hi Everyone

The original bios is problematic. Red, green and blue colors appear on the screen.
But the system does not boot. Can someone fix it for me?
