Ok thanks ibreally appreciate that.
Been trying again tonight to get it to work.
Software seems to semi work for reading, but struggling with it about.
Extracted the bin file from the .rar in post 5 but still says something about chip size etc.
Do you know what I'm doing wrong?
I'm perfectly fine on technical side software I'm not so good with
Do I need the 1.8v adapter?

its empty , you need to remove the chip then put it manually to the bios programmer maybe your using a clip?

Hi Thanks for that.
Unfortunately I snapped a leg off the chip, so currently waiting for replacement chip then will write bios to it and test.Thank you
My main laptop bios on my other 16ach6h was all Fs when I read it, this was after soldering it to the ch341 board adapter as sop8 adapter has given errors.
I've used the bios in post 5 for this do you see any issues with doing that before I solder it back on the main board.
Thanks for all your help I have learned a lot.

Hi
Sorry for delay received chips today and a socket, Managed to program the bios chip and solder on board.

Unfortunately
power light comes on, fans kick in for split second then stop and no display, Is there any other bios to try?

cpu and gpu have warmth 30 degrees
Num lock caps lock and fn lock all light up when pressed

Thanks

[Lenovochris]

will know if we test it

After going back over everything the fans kicked in nicely which made me suspicious, and i plugged in to external monitor it's fully working now so that's amazing thank you so much😃
I do have a few other bios requests if you can help me.
Thanks

[Lenovochris]

will know if we test it

Some more testing Lenovo detects a different serial number to the one my computer is.
I have display via hdmi but not on screen of laptop
Thanks
