Why won't my BlackBerry Playook charge?

I am writing about my blackberry playbook 64GB.
I received this about 2 years ago for Christmas but about 7 months ago I misplaced it and my house and was unable to find it for a period of time.. During this time it was out of battery. I recently found my playbook 2 weeks ago and it has come to my attention it is not charging at all. I was excited to get it up and running again but I don't know why it won't charge. The red/orange light won't even display. I have left it in over night but no progress has been made.
I have searched tips online but can't find a solution.
I would really appreciate a reply with a solution that is sure to work as soon as possible.

Your options are...

Stack charge it. (search the terms)
Try the PB rapid charge instead of the stock unit.
