Hi! Need clear me bios dump for lenovo thinkpad t490 (20N2, 20N3) nm-b901 rev 1.0

Hi everybody,
when I power-on my Lenovo ThinkPad T490 it make's a single bip an a single blink of both power led and charge led and power-off again.
I have read on multiple forum it can be a BIOS problem so I desolder it and I think I have a broken chip BIOS beacuse I try to read it multiple times but the result are always different and the programmer tells me that readed byte are different from aspected.
On a famous site I have seen they sell already programmed BIOS chip but I remember someonr tell's me it is not a good idea to buy it.

So, even if I buy a new blank...

Hi All, I am working on a Lenovo Thinkpad T490 liquid spill. The spill/corrosion broken some tracks & cannot figure out without the Boardview. Can anyone share the boardview for this Lenovo ThinkPad T490 NM-B901 Rev: 1 . I think ThinkPad T590 are the same. Thanks in advance

Hi all, I'm new to all this bios programming/modding. I have a Lenovo ThinkPad T490 that recently died after a bios update!

I've bought myself a CH341A and am currently trying to get to grips with what I need to do from this point! LOL

I'm a web app developer and have always enjoyed the challenge of modding (hacking) every device I get a hold of (mobile phones, Xbox, Nintendo Switch etc), so I'm hoping I'll be successful in getting my head around this as well. Fingers crossed 🤞 🤞
