Re: Lenovo L340-15IRH Type 81LK Gaming/IdeaPad BIOS Problem
Software used NeoProgrammer 2.2.0.8
I read 4 time: one by one, I erased chip, loaded your version of bios and write to chip=> no error this time.
And the magic happens. It works!
Thank you very much for your help, for your support and for your knowledge.
You saved my daily laptop!Leave a comment:

Tested the file provided => no power.
Tested the back-up => no power.

Re: Lenovo L340-15IRH Type 81LK Gaming/IdeaPad BIOS Problem
Hi @hoaca388,
I used CH341a programmer to read bios. Because I cannot find the software the next chip: 25B127DSIG I read twice with two different similar options: GD25Q127C and GD25Q128x.
I only read, no erase and no upload another bios.
Here are the file / files (used tinyhex and compare both file - no difference).
Thank you!...Leave a comment:

Re: Lenovo L340-15IRH won't start
@hoaca388 another question for you.
If I find a laptop with model 81LK009ERM in my country and I use Universal BIOS Backup Toolkit 2.0 to back up the bios on that machine and restore on mine...is this ok?Leave a comment:

Re: Lenovo L340-15IRH won't start
Hi,
I have a Lenovo L340-15IRH Gaming Laptop (ideapad) - Type 81LK
Serial Number:PF1SECN0
Machine Type Model:81LK009ERM
Black screen after I changed Secure Boot from OFF to ON.
I suspect a corrupt bios. If I read this bios, can I extract some good data? or all data will be corrupted?
Should I make a back up before? even if the bios is corrupted?
Thank you!Leave a comment:

Lenovo L340-15IRH bricked bios?
Hi,
I have a Lenovo which is my daily laptop. Today I changed in BIOS Secure Boot from DISABLED to ENABLED. I saved settings. Laptop turned off for 5 seconds and started again...but black screen. No backlight for lcd. Fans are working, Backlight of keyboard is working only 5 seconds and after that is turned off.
I tried:
-remove ram, try another one
-remove ssd
-remove wifi card
-remove CMOS
-remove battery
-power drain from lenovo website
-start with fn+r or fn+b (nothing)...Leave a comment:
