How can I read the L440 bios chip? I have the programmer but I don't know who to connect that chip to the programmer
 
All BIOS chips have the same designation on all laptops.
If you do not know please send the main board image I help find
I know already identified the BIOS. Not a problem. This is a Lenovo L440. Can I read it with a ch341A?
