Guys, so I got the same model as you.....and the same problem of the pen disconnecting randomly. In my case, I bought the pc about 4 months ago and my bluetooth part of the pen is already not functioning (ran out of battery I guess?) but the pc indicates the battery is great (the AAAA one, I think).
my solution: Pick the battery spring off the pen. You may not be able to put it back in normally,
but I PUT IT IN SIDEWAYS and re-screwed the pen with some more force than usual. Result: one small tap of the tip on any surface and it responds. Stays on too, but turns off after a presumably programmed amount of minutes. Now it works perfect. Tried it after the tinfoil bit an user suggested a few posts back.
(EDIT) Ok so I now don't recommend leaving the spring in sideways. The pen was getting really hot and when I took the battery out I noticed it was about to leak. But now I know my connectivity issue was the spring contact with the battery. I simply stretched the spring out, Ipositioned the base on the bluetooth side as it normally would. The result is the same as above, now it responds perfectly.

Install Lenovo pen setting app. It solved the problem of the pen disconnecting randomly.
Now after a month trial, I can say the pen works fine.

I have tried the following:
- Tin foil trick
- Reinserting pen nib
- Adding force on pen nib on a hard surface
- Turning bluetooth off
- Removing Wacom driver
I still don't have a proper lasting solution. Each one of them might or might not work on a particular trial. It is getting super annoying ..
