I have been hearing from a few people that have let their BlackBerry PlayBook battery totally drain having issues charging it back up again. One managed to get it working by performing a hard reset and then leaving it charging. Another purchased the BlackBerry PlayBook rapid charger and that fixed it. I have not run into the issue myself since I have yet to go below 50% battery life on the device but its an important issue since RIM does not offer user replaceable batteries on the device.
RIM did post up a knowledge base article detailing the low battery state of the BlackBerry PlayBook. It is not the most informative but it does give us details on how it works. RIM tells us that:
When the battery level of the BlackBerry PlayBook reaches a level 0%, the tablet will automatically turn off. The LED will blink in a sequence when attempting to Power On the device indicating a low charge, red blink and then followed by 5 yellow blinks.
This is because the BlackBerry PlayBook battery does not have enough charge to power up the tablet.
Their resolution is:
It is recommended to connect the BlackBerry PlayBook to the Rapid Wall Charger that came with your BlackBerry PlayBook, or one of the charging accessories listed:
- BlackBerry PlayBook Rapid Charging Pod
- BlackBerry Rapid Travel Charger
- BlackBerry Premium Charger
Please leave BlackBerry PlayBook plugged in for approximately 40 minutes or until full charge is achieved. Connecting to a computer to charge via USB will not be sufficient to charge the tablet.
Let us know if that works for you!
