OK so I've studied the procedure in particular with this video but I don't have a backup of my previous bios healthy, it's corrupt because it was badly flashed precisely.

So how can I start from scratch with an old blank bios and transfer my information to it to generate a special bios with custom dmi? Thanks

sorry when sending the file I uploaded the faulty one that was half written. I downloaded the official bios update directly from the lenovo site, can you help me again? thanks

Hello,

I'm having the same problem as you: no image, even though the PC seems to boot normally.

I hope this helps someone, as I've solved my problem.

If you've read this thread, try reprogramming the BIOS. You've checked, as others have indicated, that DIMM_only is enabled (presence or absence of resistor on the motherboard). So you may have the same problem as me.

At the SODIMM slot where the memory stick is inserted, the pins at the ends (left and right) were unsoldered.


A solder point, and the PC works perfectly.
