PlayBook Technical Support Phone Number - PlayBook Help Phone
If you just got it you're within the 90 days of "complimentary support" which is non-warranty support.
What you should try is the "de-brick"
PlayBook turned off, plugged into computer.
Desktop manager open
Turn PlayBook on
It should tell you that it is having problems and suggests you re-install the OS. Do that.
It'll download the entire OS (400MB or so) and then re-install it.
Your PlayBook will be back to normal. I suggest using it heavily because the issue could come right back. I wasn't a heavy user so it would linger and then 3 weeks later my PB was broken again.
Hopefully you're not seeing the same issue as me, but if so that's a replacement for sure
