Lenovo Thinkpad Yoga 14 (Type 20DM, 20DN)

Hello, to all .


I have problem , with this particular laptop. 

It makes "4 short beeps" i saw in the manual and it says "Security Chip , Service it by Lenovo".

And it doesn't show me anything nor boot nor post nor anything.




Tried :

Removing CMOS

Removing Charger / Battery etc.

Tried all combinations 

Tried enough things that i know off.


A friend told me ,about the 4 beeps & Security Chip ,that it may have "broken" the BIOS , and i should change the BIOS chip,any thinking ? (Lenovo headquarters are closed now,here were i live).
