Re: lenovo thinkpad P50

Hello Guys,

I'd like to ask some expert to check if my dumped bios could boot up my system, I've downloaded UEFI util, and the working dumps, what you've posted so far and compared to mine. Parser part of the program did not show differences.

If the case is that my bios would be fully functional then I would ask for a kind P50 owner to dump the flash from MEC1653 ("KBC") if it is not locked. Or dump and share it anyways for future use...

Thank You!

You can repair my older bios

You can use the bios file in #28, note that on Lenovo thickpad models there is a small switch at the bottom of the Mainboard, you need to use tape to push this switch down when the machine is operating (it will automatically press down when D cover is completely closed)

Your Backup file looks empty, try to read it again correctly.

The Compressed file size is "293.5 KB" and it should be more than that, maybe 6MB or more.

Re: lenovo thinkpad P50

when decompress 16MB...

Re: lenovo thinkpad P50

Yes I know that, but it's an empty file. If it's a good file, its size should be more than that after compressing.
