Lenovo IdeaPad Flex 5 14ALC05

[Thomas Frassineti]

Hi guys, this laptop was working perfectly, but the other day it got auto powered off because of low battery, and its not running anymore since.
Initially, it wasn't giving any sign of live, even once plugged back to the AC.

So I opened it, removed the battery, re-plugged it in, re-plugged AC, and now there are some signs of life but:
- The screen remains permanently black
- The keyboard lights up, and keeps the light up permanently (same for power button)
- The CPU fan runs
- No matter what buttons I press, or what combinations of power off/on I do, it always do this same thing

What I tried so far:
- Plug HDMI to external screen to see if something was showing there, but no luck. Tried 2 different cables with 2 different monitors, tried KB combinations to show/hide external screens etc, no luck
- Tried several other "reset" methods, but with no luck

At this point I believe the device is briked, perhaps it was doing a BIOS update through Windows Updates, and when the battery went off something didn't work, but not sure.
After searching around a little bit, I found there is a way to recover bios. I bought the necessary tools, never did it before but I can try.

More info about the device:
- Model: Lenovo IdeaPad Flex 5 14ALC05
- SN: R911YLSW
- MTM: 82HU000UIX
- MO: R9N0B131201A

If more data is needed I can provide it, thank you in advance for all the help!

It's look like that BIOS is corrupted.

look here a video as an example.. if you don't have anything to remove the bios chip from the board, stick wires between the chip and the programmer.. try to extract the content and post it here.. don't use the clip.. you might have errors..

Thanks I saw that earlier, but the link on the comments to the software is broken. Do you happen to have an updated link with correct drivers and software to use?
Also it seems like I bought something wrong, the design is identical but on the back there is CH341 and not CH341A. Might have to buy another.

Thanks

Yea I mean, the link to the video is ok, but on the video there is a link on the comments, about the software to download to use the device, and that link is broken.
I couldn't find a 100% trustable source for the software to use with this device, that's why I asked!
