Hello

I have Thinkpad T440s. I want to whitelist my bios and add Ax200 wifi card. My bios version is 2.54. I don't have bios dump. Can you please help me out ? I checked my bios chip is W25Q128FVSQ 1440.

Hi!

If you right now don't have your bios dump, then just read the first post of this thread, and create it. All instructions "how to" you can read on the first page of this thread.

Hi Klem,

 

I have a T440s that i need some help with and before i spent money on the programmer, i wanted to see if my issue can be resolved. I dont necessarily need a modified bios, i just need to overwrite my existing one with a working bios. My current bios will not allow me to boot.

 

Cheers,

Hello

My bios version is 2.54. I have attached my bios for t440s for whitelist. But I was not able to get same file in HdX comparison. I tried many time. If you have any advise why not coming same. I have attached both bin files. https://ufile.io/f/wx1fi

Ok. I checked your files bios dump, unfortunately it's not correct. You need to read your bios dump from your bios chip again, may be multiple times and compare in any hex editor (for example HxD), all dumps should be identical.

If you will meet with some problems with read bios dump from your bios chip, then try to use different software version.

All software versions for Ch341A programmer I placed into this link:  https://files.fm/u/nkp4ztcb2

I recommend you use software AsProgrammer_1.4.1

Hi!

To update your bios version, you need original Lenovo's battery.
