    WELL! after hours and hundreds attempts, I think I FINALLY managed to revive my Playbook battery. Although now it seems to have another issue...

    -I will plug it and will indicate to charge
    =Battery Guru will indicate it is about at 4v
    =I will be able to work when unplugged
    -BUT! it will randomly shut down
    -might be able to power back on, otherwise, will simply do nothing or indicate to charge it (battery drained, but there is still plenty charge left)
    -then, when unplugged, will be able to use again... untill next shut down...

    I have 2 questions :
    - Does anybody know what would be the problem?
    -according to Battery Guru, what would be a normal reading for the battery power (in watts), I have a theory that it might be the trouble...

    Thanks all!

    My next step will be to let it fully charge to 100% and then do a couple of hard reboots by pressing power and volume buttons.

    I believe BG should show it at around 9watts after a minute or two when charging (on the rapid charger). Don't recall if usb adapter is different (been too long).

    Could be a bad circuit or loss wire at battery - it should not just shut down randomly - any particular app running or just anytime?

    The PB has a one year warranty to the original purchaser. It also has 90 free Tech support. I do not know how Rim deals with "quasi-tech support v. warranty"

    Correcting that statistic...BG should report a charge of 9+ WATTS, not VOLTS. Your max voltage when fully charged will be about 4.3v.

    Also, while active, BG will report a discharge rate of 2.5 to maybe as much as 5 watts. If you find that the higher discharge rates are when the PB shuts down, then that again points to a bad battery pack...assuming that you've managed to get a full charge to start with, and having done at least the hard reset to clear whatever bad settings your PB might have picked up. If it's shutting down at even lower discharge rates, then the battery is certainly distressed.

    fixed my incorrect electrical units.

    Thus usual range give is 3.4 to 4.2 volts. The USB wall charger provides only 1800 milliamps whereas the magnetic port chargers charge at about 2400 milliamps. The magnetic port chargers actually supply 12 volts to the PB and that is controlled to supply the reduced voltage needed at the battery. If you continue to operate the PB while charging the magnetic port chargers will supply the additional power needed while continuing to charge at full rate while the USB charger will not. We usually talk about THE Playbook battery but actually there are two batteries in parallel and the charging system has to deal with the problem of charging them equally. I wonder if may not be a factor in some of these charging difficulties particularly when one battery is a good deal weaker than the other.

    And I have to correct my statement...as my PlayBook just came off a charge, the max voltage was 4.19v...I don't want to set goals that can never be obtained. Even now, after only a few minutes I'm down to 99% and 4.09v

    Thanks all for all the comments! I have a new question, Assuming the device does not seem to charge correctly (often 0.00w charge) Can I assume that it is only the battery itself that is deffective?

    Something missing is information or circumstances that might have caused the PlayBook to go dead in the first place. From a design standpoint, it seems BB has gone to great lengths to keep users from accidentally sending the batteries to such a low voltage as to cause damage. Overheating can also cause battery damage and that is something mostly in the control of the user, but not always.

    That said, going from experience with other devices, the voltage alone won't give the whole story of a battery or set of batteries. Generally, one can get the voltage all the way up but as others have pointed out, once off the charger, the battery cannot supply the wattage required to keep the PlayBook going. This is what happens to me on other devices when the batteries are no longer up to snuff.

    Perhaps, as @F2 has suggested, Battery Guru can supply the information about what is going on at the point of random shutdown.

    I would certainly give BB support a call in this matter, particularly if the PlayBook has been activated less than one year ago.
