Hi there.
Not sure if this is too late-but thought I would offer an alternative suggestion. The same thing happened to my playbook, according to a friend who works for RIM they had to recall a bunch of them for a very simple problem.
Take a look at the charging port inside the playbook, the piece inside needs to be level. You need to use a small metal object to make the piece level in the center.
This worked for me. The trick is to always keep the blackberry symbol facing upwards, if it is put down, it ruins the alignment of the piece again!
Hope this is helpful. It saved my playbook :)
