If the laptop is still under warranty, I suggest that you ask for it to
be replaced or at least to be fixed.
I understand that the beeps form the pattern of 2-2-2.
According to the
Troubleshooting POST/startup does not complete issues - Servers,
this pattern may mean "Keyboard controller failed" on the
System Board.
You should also examine the screen while the beeps are issued,
to see if any messages are issued (if the messages disappear
too fast to read, film the screen with your phone during the boot).
The error might be different from my above interpretation, but it's sure
that the problem is hardware.
Try to disconnect any possible device and boot.
If nothing changes, call Lenovo Support for this problem - it's not
something you can analyze or fix.
