I started having charging issues with my BlackBerry dock. I came on crackberry to see if anyone figured anything out and saw that a few people had problems charging the playbook using the dock but nothing worked for me. My boss playbook still started charging and then stopped. Sometimes I would get the charging indication but it would go away in a second or two and sometimes it would stay and still not charge my PlayBook.
Finally I went and bought a new dock but still had the same problem. I started looking at the playbook and noticed that the contacts on my PlayBook looked dirty or oxidized. I took a paper clip and gently twisted the end of the paper clip on the end of the playbook contacts. That seemed to have clean the contacts off and now I don't have a problem charging my PlayBook on the dock anyone more. I thought I would post this in case it helps others having charging issues.
