    There are a few solutions and some are mentioned above. SO try the things I am mentioning below.... Let me know if it works .

    Problem Scenario: 1. Blackberry wont boot or turn on, on pressing the power button, the red light stays for a few seconds and does not turn on 2. Sometimes you will see the red light followed by a green/ yellow light that blinks 5 times and does not turn on.

    Reason: The main reason why both of the above things happen is because the battery is completely drained out, you could call it " Flat out". The problem with playbook is that the playbook wont charge if the playbook is Flat out drained. whereas other tablets or cellphones does....Playbook has to fix that issue. Meanwhile we do have a solution to go around that problem and that requires some patience. Some of the solutions mentioned in the previous comments indicate to charge it via computer.... "It doesn`t work" not if the battery is drained out flat.... so dont even bother trying it if u see the above mentioned problem.

    Solution: try this step by step and this are 3 different solutions so one of this would definitely work. 1. Press the Power button and you will see the Playbook Logo ( chances for this are low ) 2. Press the power button and the volume together, if there is 1 % charge left there is a chance that it would boot on, when you see the logo, immediately charge the playbook ( chances are medium ) 3. This solution requires patience. plug the charger into the socket and plug the USB into the playbook, the red light stays for 8-10 secs. Remove the USb from the playbook wait for 2 to 5 sec and replug the usb back to the charger and wait till that red light comes and goes again. repeat this step atleast 20-30 times. you might be asking why? the only power that the playbook gets is when that red light is on when plugging the usb into the playbook, once that light goes the playbook is not charging.. so what you are doing here is forcing the playbook to get charged for 8 sec every time u plug it to the playbook....this way the playbook gets that power needed to boot. Once the Playbook has that power to boot. The red light stays and changes to green but this time it blinks slowly and keeps blinking. you would also see the playbook logo return.... this green light keeps blinking until there is enough charge for the playbook to stand on its own and then changes to a solid red until it gets fully charged. Hope this helps, I had to explain to you guy what the cause was and how it is overcome..... so let me know

    Hi,
    Some weeks ago, my playbook wont boot up and no wanted to charge after the playbook was totally drained.
    I try all solutions you mentioned, at start i could see the red led, but nothing after. I try the tip with the three buttons too, to plug and unplug 10-20 times the charger, ...
    Then I plug the playbook on the rapid charger, go to the church and every day i tried to boot but it didnt work. After 5 charge days, when i was decided to bring it back to the customer service, i took her and, amazing she was alive!
    During 5 days, no life sign, no led, i was desesperate and the miracle arrived.

    So, if all the previous solutions failed, just try to let it a week or 10days (it work for me with the quick charger).

    Hi,
    I'm kinda confused about the 3rd step. It says you have to use a USB to make it work. Can you do that step with the charger instead?
    thanks

    I had the same problem of not being able to charge my playbook after the battery went flat. I was going to buy a new battery but found the expense prohibitive. Therefore I just filed my playbbok away thinking it was toast. After leaving it for a couple months (and buying an Android Tablet) I was going to chuck it but thought I would give it one more try. Low and behold it started to take a charge and all is good now. Wierd but nice. Makes no sense to me but whatever. So try leaving your dead playbook alone for awhile and try charging it again.

    You must use the included charger. The USB cable to PC will not work. I believe he means the USB charger.

    Just to clarify one other point. The slow blinking green LED indicates the PB is charging and turned off. When it is fully charged the light will stay on and be the same green color. Not red as described in the post.

    My Blackberry Playbook seems to be in a worse state than anybody else's, at least they are getting lights of some sort. Mine was working perfectly OK, I turned it off and when I tried to turn it back on it was completely dead, no sign of life whatsoever. Plugging it into the mains does nothing. When I use the USB cable into my PC nothing happens, the PC doesn't see it. I just have a very expensive coaster to rest my cup of coffee on.

    Do a forum search for stack charging.

    What was the battery level when you turned it off and how long before you restarted it?

    As far as I know the battery was fine, I usually use the Blackberry plugged into the mains. It was plugged in when I turned it off and still plugged in when I tried turning it on about an hour later. I've tried it unplugged as well. I did nothing different to what I've done dozens of times before. It's only a few months old, but can't remember where I bought it and don't know where the receipt is, so there's no possibility of taking it back.

    If all else fails or you just don't feel like messing with it call RIM. You don't need proof of purchase. They will troubleshoot with you and replace if needed. You have a one year warranty.

    First try PRESSING and HOLDING the power button for 15-20 seconds. Let it go and then wait another 15-20 seconds or so and see if the RED led comes on. The red light is NOT immediate. Do not rush it.

    Stack charging:

    Don't keep trying if you get the Red light/5 Yellows... you'll soon drag the battery down past where you can start it again. Leave it off, plug it in and let it charge (with at least a 1.8A charger). Once you get the flashing (once every few seconds) green light, you can power it up - on the charger. If you do drag it down below the red flash/5 yellows, plug it in for 1 minute, unplug (at the wall) for a second or so, plug it back in and repeat for 20-30 minutes. You'll eventually get the red/yellows and then leave it plugged in (and off) until you get the flashing green. It's a PITA but the PlayBook has a very conservative charging algorithm when the battery is below 2.67 Volts to prevent explosions (I'm guessing). I've never been unable to start one with that method.

    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!

    Thank you for taking the time to give such a full explanation. I tried everything you suggested. I plugged/unplugged the charger, it is the one that came with the Blackberry, every minute for an hour with no result whatsoever. It was a very long hour. By the end I had lost the will to live just as my Blackberry obviously has. There comes a time when we must learn to say goodbye to our dear departed, and I think that point has been reached. Once again thanks for your help.

    Mine just did the same thing as yours,could not get it to get any lights to come on,it seemed dead.Took the power supply and plugged it into a different outlet and the red light come on and now its working.

    I've already thought of that. I've tried it all over the house. In each case I've made sure the power socket was OK. Still no joy. I have a power plug that takes USB and gives 5V. the same as the Blackberry charger. I tried this with the USB lead that came with the Blackberry in case the original charger and/or lead was faulty. Still no good.

    Did you try with the original usb charger that came with the pb. Some folks suggest that it might have different wiring/circuitry that signals the pb as opposed to a generic charger even with the appropriate voltage/amps.

    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.
    Actually, the Low Battery Warning occurs at 3.5 volts. Actual auto-shutdown doesn't happen until 3.40V is reached---at which point the battery only has 2-3% of residual charge available. This is the heart of the problem. I'm sure the engineers wanted the shutdown at 3.5, but they were probably rebuked by the marketing geniuses who desperately wanted the PB to have a longer run time than the iPad.

    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.

    Agreed. The simple key to avoiding the problem is to either

    1. Stop using it as soon as the Low Battery Warning appears or
    2. Immediately recharge the PB whenever it shuts itself off.
