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 flashed the bios of my lenovo 15ADA05 with the latest bios available on lenovo. Unfortunately, after the installation procedure with continuous sounds, I had a black screen and tried to restart. Then the computer remained with a black screen on reboot and the fan running normally. Impossible to launch the bios. So I dismantled the computer and tried flashing with cha341. I was able to read the current bios and saved it. I tried to rewrite on it with a bios found on bios archive but it doesn't work.
Here is the information to help me get a dmi and a blank bios to remake a bios with a custom dmi:
Ideapad 3 15ADA05
MODEL name: 81w1
SN: PF3NTMCG
MTM: 81W1002GFR

you have everything you need at post #29..
https://www.badcaps.net/forum/troubl...-15ada05/page3
for DMI information..
the bios from post # 29 is virgin, use the HxD program (it's free on the internet), enter both bios into the program (your laptop and the virgin one),
select that interval mentioned in both bios, copy the interval in your bios and pass it to the virgin bios (copy - paste)....and that's it...

Hi All
I have an IdeaPad 3-17ADA05 -
Serial PF206XN8
Model 81W2 -
MTM 81W20056FR
that presented errors that seeme d to indicate onboard RAM issue.
I tried to disable the onboard ram following the instructions here [ solder-desolder resistors] but had no boot
I copied the DMI info to a downloaded Bios Bin as per this link
https://www.badcaps.net/forum/troubl...pt#post1214739
and got a boot ,but the system crashes with ACPI error after 5 minutes every time.
Attached is the original Bios Dump and the one that sort of worked
Thanks in advance

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... -
Model: Lenovo IdeaPad 3 14ADA05 81W0
S/N: PF2BZS7D
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....
