Re: T470 bios needed
Hello, I don't think the BIOS is the problem, just like every newer Lenovo, the capacitors and resistors are very close to the chip.
We don't know how the BIOS was read out with a clip or by de soldering the chip.
The experienced users in this forum will de solder all the chips in order not to damage anything.
With the clip, resistors are all too likely to be damaged and then nothing works anymore.

Hello, I was flashing the bios but now the machine does not come, the battery indicator turns orange when charge is plugged in.

Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).
I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...11-17-2023, 10:56 AM -
