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

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.

Hello.
I have a Lenovo IdeaPad 3 14ADA05 that it dosen't turn on.
It takes 0.027A and the power button flashing.
All the voltages on the board are ok. 3.3, 5 etc.
Also is charging the buttery .
What else i can check?05-26-2025, 01:03 AM -
First off, I saw the other thread, but that seems to be a different version (same model though), because I tried all of the linked bioses and none work. They actually cause the laptop to do nothing. At least when I use the bad bios, lights come on. (charging light, power button light, and caps lock light), but no screen.
Another thing is that the bios has a different name (Old thread has "e8cn36ww" and mine is "fqcn31ww") and the BIN in this thread (below) are 8mb, and the CAP file that I get is 16mb (after using innextract 1.9). I don't know how to get the BIN... -

I was having issues with this particular laptop where the NVME SSD would disappear and would not detect unless I took it out and reconnected it, then it would detect for only for a minute then disappear from BIOS. I figured updating the BIOS was worth a try so I booted into my HBCD USB and downloaded the latest BIOS file for that exact model. I ran the executable and everything went smooth, it beeped and then when it restarted, now it won't post, just black screen with fan spinning.
I already have a CH341A programmer... -
Lenovo IdeaPad 3 15ADA05 Model: 81W1, how to disable onboard MICROTEC RAM?
Laptop freezes, sometimes no picture. POST every time with 4GB additional memory but still freezes in the windows.
SSD and BIOS seems to be OK.
Thank you....
