Bios Mods -The Best BIOS Update and Modification Source

Wow! That article by Matthew is very interesting! It makes me want to start disassembling my laptop's EC! Thanks for sharing these links BDMaster!

As I am still focused on learning how to modify Insyde and Award UEFI images, as well as learning new modding techniques for Phoenix/AMI UEFI, I am going to have to take back my modification offer for now as it is very involved.

I wish you all the best of luck!

Now integrated my B590 battery patches into thinkpad-ec project as a pull-request, so permanent flashing should now work too.

Hi there,

I am looking for some help in order to disable the battery checking. I've tested out the github workarround but it seems it doesn't work for my old laptop.

B590
Bios Version : H9ET73WW (1.10)
EC version : H9EC07WW (1.00)

I also have done a backup but maybe it was done with the wrong tool (Bios backup toolkit 2.0) -> https://www.sendspace.com/file/iy5ef9

Thanks!

Hello! I need help since new battery says "The battery installed is not supported by this system and will not charge". Me laptop is:
Lenovo B590
model name: 20208
UEFI BIOS version: H1ET85WW(1.23)
Embedded Controller Version: H1EC34WW(1.14)
I tried github links mentioned on previous pages without any luck. Every tool says I either have unsupported BIOS or EC. I tried to flash another BIOS but there's only 3 version at lenovo site: 75 without any manual how to install it, 84 (says I have the same version) and 92 (says I have incompatible hardware). Anyway, I doubt flashing the official BIOS would do any trick. So here I am asking for the help.

I tried to dump my bios with FPT but it fails saying I can't use this tool with my hardware (laptop is intel core-i3-based though). And I can't find any link to download BACKUP_Tools19 anywhere. Can you help me with just that for the start?

Thanks in advance!
