Hello eweryone

I have a Lenovo Legion 5 that is not turning on, no display, only the power button lights up, I tried to flah the BIOS with the file at post 61 but nothing changed. I tried also with other files but neoprogrammer return an error like FILE NOT Open. I attach also a saved backup bin file with original bios. Thank's!

I've already tried, with neoprogrammer doesn't work (It's returning an error like file not open when I try to open the file), with asProgrammer I can open the file also seems like it's flashing the chip but nothing changes. I tried almost every file fount on this forum but nothing seems to work. Thank's!

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=ThisIsHow

I've used the same programmer showed in the video, the software I've used is the neoprogrammer, and I had reading succes but almost no succes in writing, only if I flash the readed file. I tried with asprogrammer, I had write success but the problem is not solved. I soldered de wires from the beginning because with the clip I had no success at all.
Thank's for all the advices.

hi, read all 12 pages and i share a problem with a few of you. This is my personal machine and it happens while i was randomly installing bf6, the computer freeze, no blue screen, i restart it and boom, keyboard lights up, but no image. all the coils have voltage, i flashed the bios from lenovo and change the dmi with what it says in post #5, i tried multiple files but with no avail. i think is the bios as the machine was working ok the day before, no high temps or anything like that, right now i'm running out of ideas. here are my original files, and 1 that make the computer boot 1 time, and then never again. i tried multiple sticks of ram, even new ones in different configurations. lenovo legion 5 ryzen with rtx 3060 SN: PF3M4XLA. every flash was made using a SPI programmer (i have a SOFI SP16) taking of the bios chip and soldering it to an adapter. also some times it consumes 20w and others 40, with the battery disconected, using a bench power supply

it still has the same issue, now it peaks consumption at 26W, processor and gpu heats up a little but still no image, i did not flash UG10 or UU137. i don't know if that can be a problem

Unsure about UG10 or UU137. Try these files...

Hey guys,

Im struggling with a Legion 5 - 15ACH6H SN: PF3L5V66. i can not get it to boot.
When i turn it on, there is no fan spin. no keyboard backlight, just the power light on the button is lit.
Black screen throughout the entire testing process.

Also, usually when i make a bios dump the file is 16 MB and now it turned up only 2MB. not sure if this is correct.
Here is the dump that i made.

im sorry in advance if i made some violation of the rules i tried to follow guidelines as much
as possible, this is my first post here.

post merged..next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..
