Why does my Blackberry Playbook every few minutes asks for my password and how do I fix it

that normally means there is fault with either the battery or the charger

You need a Blackberry charger. Other chargers might fit in the slot, but won't charge your device. You have to use (buy) a fast charger if your tablet is completely discharged and won't turn on. They're about £20 but worth it to keep using your Playbook.

My tablet is not working right now... the andiood guy stay on there for long time and it wont go on home screen.... Anyway i can get a replacement new tablet or get it fix or new charger

I had many problems with my playbook. 1st thing you want to do is hit the power button on top if the playbook is still not on hit the volume up and down at the same time (I do right then left) then push the power button and sometimes it will be on.

this happened to me, it needs charging make sure the lead has the blackberry symbol facing up....

Nope, you actually cant insert a sim card in the blackberry playbook.
That is possible only in other tablets such as the Ipad.
sorry :)

The Playbook attempts to download the license agreement from http://csbeta.websl.eval.blackberry.com/
and it seems this URL is no longer valid, as it returns
"Sorry! Nothing could be found here."

i figured the OS on my playbook is an early release so i'll be forcing an update.

to force an update, i fired up the latest desktop manager, completely turned off the playbook by pressing/holding the power button then clicking turn off, then i plugged it in..
desktop manager then shows an error message and gives you the option to update.. click that and leave it alone for an hour++ (depending on your internet connection)

i started the updated playbook, went through the setup wizard and this time when i selected the country, i got the license agreement and was able to continue.

option 2:

Ok, for your first problem, I couldn't open a couple of file types on the playbook at first either. Go to the app world and download the free app called "airbrowser." It lets you do various things such as delete files, and allowed me to find and open the documents I wanted.

As for the email issue, I would suggest retrying the bridge. Go to the bluetooth connections screen on your torch and delete the playbook, and do the same on the playbook to delete the torch. Then start from scratch reconnecting via the BB bridge app. It solved a few issues on my playbook as well.

If you can't get it shut down, then try leaving it on but unplugged until the battery is completely dead. Hopefully when it is plugged back in and charged for a few minutes it should restart normally. If this doesn't work, then you should contact Blackberry Tech Support for your area, they are usually quite good to deal with, but I suggest contacting them by phone as email can be cumbersome and take several days to make progress. Their phone number for your country should be on the website. Obviously your playbook is still under warranty as it wasn't released more than a year ago.
