sir for this same model JE442 / JE542 NM-E211 can you clarify how to clear the bios locked? because i just opened up mine and there is no bios chip on the JBIOS slot
What do you mean you don't see the BIOS chip?
 
where exactly is it? or please do teach me how because i am new to this

If you do not have experience, I advise you not to touch the motherboard as it may be damaged immediately.

For lenovo, if you want to unlock the password, you need to back up the I/O, which is very difficult

i welcome the challenges and i got extra donor board just need a guidance in details if possible.

to back up the i/o, it can be done using the CH341A usb, correct?
