Hello All!
I've IdeaPad 3 15ADA05 Laptop - Type 81W1
S/N: PF2972BX
GS550 logo on left panel
GS450&GS550&GS750 NM-C821 REV 1.0
At first it sometimes powered on and showed display, but often froze even in BIOS or just goes black screen after a few minutes on screen. When it reached the Windows 2 times PIN screen, the display went black.
After that it only powered on with a black screen.
I flashed NM-C821 DUMP.BIN, and the TPM reset screen appeared right away.
Then it froze at the Windows logo then restarted and froze with an IRQL_NOT_LESS_OR_EQUAL BSOD.
On the 2nd boot it black-screened again, and from the 3rd or 4th attempt there was no display at all.
Wierd that I pluged charger in laptop turned on without press power button..
Now, on AC power without battery, the power LED blinks, CPU fan spins, but there’s no display.
After reflashing the same BIOS again, on first power-on the CPU fan spins briefly then stops (power LED stays on);
on the 2nd boot the fan spins continuously after about a minute;
and since then, it always spins but still no display.
I’ve also tried the latest forum BIOS E8CN41WW.bin, same result but now when I plug AC power in laptop wont turn on automatically.
Flashed with NeoProgrammer 2.2.0.10 + CH341A Pro (black edition with green 1.8 V adapter).
Chip: Winbond W25Q64JW.
Verify always OK, no errors.
Any ideas what could be wrong?Comment

you have everything you need at post #14...
The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..
you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHowDue to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:

Hello.
I have a Lenovo IdeaPad 3 14ADA05 that it dosen't turn on.
It takes 0.027A and the power button flashing.

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

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....
