Re: Lenovo ideapad 5-14IIL05 BIOS bin

Unforunately, just this one repair on my own laptop but I have enjoyed learning all the info from your site. So now that I have seen the programmer costs so much money, I am stuck and thinking I have no choice but to take it to a repair shop

Unless you can think of anything else I can try first but I think I need to re-programme the EC chip as well right, now that I have written to the BIOS, as the laptop still doesn't get past the black screen.

Ok, that makes sense now. Thank you. But I note that those EC programmers are expensive

If you`re doing a lot of laptop repairs an EC programmer is a necessity.It will pay for itself eventually.

Re: Lenovo ideapad 5-14IIL05 BIOS bin

You would need a dedicated EC programmer. Popular models are Vertyanov SUCCESSOR ,SVOD4 ,RT809H

The EC chip is KB9052Q . Schematic - https://www.badcaps.net/forum/showth...light=LA-J551P

The pinout for the programmer connection is LA-J551P KB_pins=34 LEFT DOWN 08MM KSO3=9 KSI4=22 KSI7=25 KSI6=24 KSI5=21 KB9052Q .

You can`t program it with a CH341A afaik.

Hi all, I saw that in post #7 @SMDFlea provided two files for the Ideapad 5-14IIL05 Laptop 81YH.

File DSCN34WW (DOSFLMS0).zip 6.20 MB
File DSCN34WW_EC (DOSFLMS0).zip 62.5 KB

My question is, how do you write the EC file to the motherboard?

My question is, how do you write the EC file to the motherboard? My motherboard only has one BIOS chip and I have applied a new BIOS .bin file provided to me by @qayyum786 in another post but the laptop is still not working and I am thinking that maybe I need to also apply an EC update but I am not sure how that needs to be written and if it needs to be modified for my laptop. Thanks.

Re: Lenovo ideapad 5-14IIL05 BIOS bin

I read the file with CH341a and the issue is identical as the first post.Blinking led with short fan spin and no boot.It's a Lenovo 15-14IIL05 (R90ZTFQ0) 81X1.I have attached the original dump if anyone can help....

You need the bios attached at post #10, use the information about the DMI and Windows key offsets at the attached txt file to transfer them from your dump to the new one.
