DELL PRECISION 3640 bios

[gungor1981tr]

Hi
The device has been de-energized during the bios update and tries to update the bios every time the device is plugged in, but the operation fails.
The error he gave at the end of the operation is written below
The device is in recovery mode or I can't boot

(Bİos update blocked due to unsupported downgrade) and the device turns off

hi
Thank you for your concern
The bios dump edited to the device worked, but the computer comes to the desktop on the 5th boot after turning on and off 4 times, I think it is necessary to clean the bios file

Sir, I request you to edit the bios file,

The system works after switching on and off 4-5 times and the time required for the system to become operational is 3-4 minutes

DELL Tower 3640 SN: 3KLPM83. The computer behaves correctly until it is turned off. Then it does not respond to the power button. A hardware problem is excluded. I encountered the same problem in DELL 3080 micro. Only BIOS, which allows you to enter the SN again and assign the product model, allows the computer to start correctly. Of course, then you have to exit service mode.
