    Recently I've started having problems on boot my PB.
    A couple weeks ago, it suddenly stopped charging after battery be bellow 10% of it's capacity.

    I just get a black screen, NO lights flashing ( red or green ) or no signs it's charging. Equipment simply looks "dead"

    I've tried all recommend solutions found on support sites ( e.g. CrackBerry, BB KB etc ). So far without any positive result, after many hours / days spent on trying to get this fixed.

    The only thing I didn't tried so far, was try to load it using a rapid charger, as I didn't had any available.

    Can you please assist me? What actions can you recommend?

    Are you sure that the ac charger works? Have you tried using the adapter with another device that uses the micro usb plug? Have you looked into the usb port on the pb and made sure that the connector is not bent or slanted out of position? First stack charging and then Rim contact info.

    Here's the advice from one user on stack charging:

    Mapsonburt:

    The PlayBook OS currently shuts down at 3.5 volts. When the battery gets below 2.67V it won't show power lights or even try to start because there isn't enough juice to even power the processor to run the code on the BIOS. The BIOS is software hard coded on a chip within the PlayBook that tells it how to load the PlayBook OS and is coded such that it only recognizes signed PlayBook boot images (which is why it is so hard to root and that nobody has been able to get one to boot Android or WebOS. The BIOS software also contains some charging algorithms for when the OS is not running - ie device is powered off but plugged into a charging source. This code ONLY runs when the battery is above 2.67 volts because the processor can't run below that.

    The root of the problem is that this design issue prevents the device from accepting any charge longer than 60 seconds when the battery is too low to run the charging algorithms on the BIOS or on the OS (one runs before the device is powered on and one runs afterwards). RIM did this because Lithium Ion batteries have a nasty habit of catching fire if not charged properly so they wanted to ensure that the processor could be in control of the charging. Makes perfect sense and they probably thought they were avoiding situations like where early Li Ion batteries on laptops were catching on fire. The problem is they were a bit too aggressive in dealing with the problem at design stage. If the battery is below 2.67Volts their protective algorithms can't run but you also can't put enough charge into the battery to charge it! Hence all the reports of people having success with stack charging.

    Unfortunately there are a lot of wrong ways to do this floating around out there and getting repeated everyone someone posts a new thread on the issue. It really should be made a sticky. What is the right way?

    1) ONLY use a source that provides 1.7Amps or more of charge. The original charger provides this. The rapid chargers provide a lot more. Your phone charger only provides a fraction of this. Anything less is going to take forever to charge the battery above 2.67 volts and may not have enough juice to charge the battery AT ALL once the processor starts to run above 2.67Volts or even worse once the OS starts to run above 3.5Volts. Forget about using your computer to charge it when the OS isn't running as the computer looks for the hardware to identify itself and won't put out a full charge current unless the device indicates it can accept. Once the OS is running, you'd often CAN get enough power from the USB on the computer but that is because the OS has signaled it is OK for the computer to send it. When the OS/BIOS isn't running, the PlayBook won't take much/any charge from a computer. The rapid chargers are best as they quickly charge but more importantly do not use the (too) flimsy USB port. A lot of problems are caused by this port getting wobbly over time and the device not getting a charge at all. Everyone should have a rapid charger.

    2) Until you get your device WELL above the 3.5Volts that let's the PlayBook boot, do NOT try to start it. Every attempt drags the battery down some more and that attempt sucks much more charge from the battery than you can put in in those 60 seconds before the hardware shuts down the charging. How can you tell where your battery is? Well if you are getting no lights on the playbook on your first charging attempt you are below 2.67volts. If lights go on and then it doesn't start the OS it is below 3.5Volts. If it loads the OS and then dies it is just above 3.5Volts. If the device loads the OS it is somewhere below 5.0Volts. Depending upon where you start (how low the battery is) various techniques work best. They are: REAL stack charging (plug in for 60 seconds, unplug, plug in for 60 seconds, repeat until the processor starts accepting charging (the big battery symbol on the screen). Again, DO NOT try to turn the device on until then. You are just working against yourself and it will take much longer. You should get the charging symbol within 20-45 minutes of repeated REAL stack charging. Forget you ever heard of plugging in for 2 mins and then off for 2 mins and similar as those 2 mins of off time are COMPLETELY worthless. I have put a multimeter on the PlayBook in this state and it NEVER takes more than a minute of charge when under 2.67volts but will accept another minute of charge after a short (1-2 second) disconnection. Just do it right.

    3) Once you see that charging screen leave it plugged in to the charger (stop stack charging) for at least an hour before you try to start the PlayBook. If you don't you may end up in a situation where the attempt to start drags that battery back down below 2.67V and you have start stack charging again. Be patient, you are almost there!

    4) Fully charge your Playbook after this to ensure your PlayBook gets back to 100%.

    Unfortunately, there isn't a lot RIM can do about this now. It's a hardware design issue. I'd be interested in knowing if the fixed it with the 4G versions. I don't think I've ever seen that complaint with one of those but I've "fixed" both of mine a few times (the kids keep trying to power them on after letting them shut down on low battery despite me saying time RUN not walk and put it on a rapid charger when ever it hits the flashing red battery signal (9%). I've also helped many friends and people on the web and NOBODY who has followed the instructions has failed to get their PlayBook to charge.

    I'm convinced this fault is the reason so many PlayBooks are returned to the stores and through RMA. RIM has been very good about this but it should never have happened. Happy Charging!

    The steps F2 posted will work (most times) if there are no problems with the charger or connection.
    Patience is the most important part.

    If none of these steps work I have had success with disconnecting / reconnecting the battery.
    It's not that difficult to do but I don't recommend it if your Playbook is still covered by warranty.

    Lets us know how this is working out for you.

    Try PRESSING AND HOLDING the Power button for 20 seconds or so.

    fix an issue, try these in order:

    Restart using the Battery Icon and press Restart

    Press and hold the Power button for 10-15 seconds. Then leave it for 20-30 seconds and see if it restarts.

    To REBOOT:
    Press and HOLD all three keys for about 10 - 20 seconds: PowerOn, VolUp and VolDown. Start with the PowerButton. Keep holding past the 3-choice options screen. If you hear a shutter type sound, you've taken a Screen Shot and probably missed the PowerButton.
    ---------------

    You might need to debrick

    Try the Debrick method....

    Perform a backup of your pb if you can using Desktop Manager or, at least, manually coping any unique data, photos, voice recordings, documents, etc.

    1) Turn your playbook OFF by holding down the power button
    2) Let your playbook sit for about 10 minutes as earlier suggested.
    3) After letting the PB sit (and still powered off) open up the Blackberry Desktop Software (the latest version)
    4) Once the Blackberry Desktop Software is opened, use the USB Cable and hook the PB to the PC.. THEN power on the Playbook
    5) A screen will show on your computer showing that the device cannot be found
    6) Click on Update. It will take awhile

    Leave it attached to the rapid charger for an two or three hours and do NOT try turning it back on - just leave it. If it does not seem to be charging, then try Stack Charging and you can use either the regular or rapid charger.

    For Stack Charging see reply #2 above.

    Good luck

    He charged all night, but its hard to give him charge. I must plug the charger 5 times to have connection.
    ill try another 2 chargers later!
    My rapidcharger doesnt acumulate energy too. just work while connect to the wall.
