I recently purchased a laptop GT83VR 6RF and i will be traveling from Toronto to Hong Kong with "Cathay Pacific", will my laptop and it's large batteries be allowed on the flight? And will i also be allowed to use it on flight? Thanks.

If the battery is attached to laptop then it's fine. You can use laptop after the plane has reached crusing altitude, the pilot will make an announcement.
