Trying to fix a BIOS corruption issue on a Lenovo Legion Pro 7 16IRX8. The motherboard model number is 5B21L45527. First of all, can folks confirm which chips need to be dumped? Images of the top and bottom of the board are attached.

Lenovo Legion 7 Pro 16IRX8.
MTM: 82WR0000US
S/N: PF48QSDX
1st BIOS chip: XMC 25RH64CHIO (used XM25RH64C in Neoprogrammer), second chip XMC 25QH128IO (detected as XM25QH128C in Neoprogrammer)
Chips have been dumped with CH341a (w/ 3v mod) using Neoprogrammer with chips soldered directly to CH341a. A test clip was not used. But I believe the person who looked at it initially did try to program it using a test clip so it's quite possible the chips could already corrupted.

Thanks! I tried flashing these. System posts on but does not post. Fans run, keyboard backlight comes on, screen stays dark, no response from keyboard. After around 3 minutes there's a loud beep and it turns off, then it powers back on in around 10 seconds and this process repeats. Tried letting it sit 20+ min in case it was still going through BIOS reset process but no change. Thoughts?Comment

Hello,
I'm using TONGFANG "GM7TG7P" model laptop for over 3 years and i'm entering the same bios administrator password everyday. My laptop has Aptio BIOS (American Megatrends, AMI).
But today it's not accepting my password. I'm %100 sure i'm entering the correct password.
I'm trying to reset my bios without success.
I tried :
-I removed the BIOS battery and main battery. Waited for a long time but it didn't work. They already stated in the user manual that the password will not be reset even if the batteries... -
Hello everyone, I come here to tell you my problem regarding the power-on password. It is not a bios reset demand, and i can't have any access to windows. This is the bios and power-on password that is blocking all other things.
My Omen 15-dh0052nf purchased second-hand was configured with the bios password upon purchase (very simple password :P ).
Having decided to sell it in order to get something more powerful, I reset all BIOS settings and set a blank administrator password. But the power-on password cannot be changed to a blank one so I let the actual password set.... -

The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.
Troubleshooting Attempts:
