Thinkpad L440 stuck/bootloop in Lenovo Diagnostic screen

So what happens is when I start my laptop it beeps once and straight goes to lenovo diagnostic screen. I ran all the diagnostics, HDD, RAm etc and it all passed.  I exit the aplication then the laptop restarts and again goes to Lenovo diagnostic screen on its own.

 

Cant even access boot. When it says Press Enter to disrupt boot , even pressing enter does nothing. It straight goes to , Lenovo Diagnostic. Please help.

Were you ever able to resolve this?  I have a L540 that is doing the exact same thing.

It was a faulty keyboard key. I changed the keyboard and voila all was well.
