Bios for Lеnоvо IdеаРаd 5 Рrо 14IAР7

[sergei66666]

I search bios for this model.

S\N: MP2CP9W5
MO: MPNXB2B2101F
MTM: 82SН005ЕRK
Board: Compal HLI42 LA-L961P Rev1.0

The laptop responds to the power button, the indicator next to the button starts to light, but there is no video.
The hub starts to heat up a little.
A small inspection showed that all power supplies are raised, except for VCC_CORE and VCC_GT - there is no exchange on the SVID bus between RT3624BE and the processor.
Power consumption from a laboratory power supply (when connected instead of a battery) is 13V, 370mA.

Perhaps the problem is in the BIOS (original image is attached).

I tried to implant the BIOS image from the Lenovo website - it did not help (the original image is equal to the BIOS image that I got after combining the image from the website and adding DMI). I also tried to clean ME - it did not help (most likely I did something wrong).

I would be grateful for your help.

p.s. The laptop has already been to the repair service. I assume that some manipulations were carried out with the BIOS. But, fortunately, the DMI region remained untouched. Perhaps a cleaned dump from a working laptop will work.

post the original bios again, the one posted cannot be downloaded..

Done, boss!

I also apologize for the long response (in the settings, the option to receive notifications about all events was selected, but something went wrong and I did not receive an email).

ps Looks like there's a glitch on the forum. Many links are not working at the moment.

pss Definitely a glitch. The attachment I just sent can't be downloaded.

It seems the links in other topics worked. So, attempt number 3.

can't download...post the bios on another site so we can download it from there...

Thank you. I uploaded it to Google Drive.

Got a response from the forum support with a recommendation to attach the file again - attachments should work. So attempt number 4

ps Initially I tried to add an archive with three files (dump of the first and second flash IC and their combination) - it didn't work.
Then I made an archive with one final file - the attachment can be downloaded successfully.

Thank you very much for your response!

I flashed the BIOS and, to my regret, the behavior did not change - static consumption of 13V, 370mA.

After a couple of attempts to turn on, I read the contents of the flash IC.
The contents of the large flash IC remained unchanged.
The contents of the small flash IC changed in two places:
1) 72 bytes at address 0x2C2000 (beginning of block = "FCRI")
2) 64 bytes at 0x2C3000 (beginning of block = "FCNT")

I will continue to study the board.
