I can not sync my One Plus HP running Cyanogen to my laptop "Samsung Lite 9 Book"

[AC Question]

I tried to sync by Bluetooth or by USB cable but it did not register with the laptop.
Every time I activate Bluetooth on my phone,it revert back to inactive button after a few seconds.I tried a few suggestions from the internet but it does not help.
Shall be much obliged for help.Thanks.
