    Hello all:

    I know these tablets are older but, I still see active chat about them here in the forum, so I thought I would inquire if anyone has seen this.

    I was given this PB and was told it had the most current software and that it worked until it was left and forgotten. I've been able to get as far as the sequence written below, which just repeats itself. I have the original BB charger with the output listed at 1.8 amps. When I plug the cable into the PB, this is what I get.

    Upon plugging in the cable to the PB, there is a delay of 4 seconds, followed by a red solid light for 16.7 seconds

    Next nothing shows on the PB for 7.6 seconds.

    Next the battery with the lightening bolt displays for 19.5 seconds on the screen, no LED's at this point

    Followed immediately with a steady green light for 7 seconds along with a black screen.

    Lastly there's no activity for 4 seconds, before it all repeats itself.

    Prior to the sequence ending it has done different things. Once it ended with the red LED staying lit for close to 4 minutes then nothing, another time the red LED was on a short time followed by 5 yellow flashes before no activity presented itself.

    Every times I pull the cable from the tablet and re-plug it in, the sequence restarts and seems to get longer in the number of times the sequence repeats itself. The first time it only ran the sequence a few times but, the last time it continued for close to 30 minutes.

    As I write this its currently replaying the sequence over and over, as mentioned it seems to get longer each time I plug the cable into the PB once the sequence has ended. Currently well past 30 minutes this time.

    Is this some sort of odd method of charging I haven't read about or something more serious?

    Any thoughts? Thanks for the input.

    Cheers

    Sound like the battery is drained.... when that happens the PlayBook requires stack charging...

    Thanks for the reply D.

    A bit of an update but, first, I was under the impression that if you got an LED to show, followed by the battery symbol with the lightening bolt there was no need to "Stack Charge" and that the PB should now accept a charge.

    To try something different I decided to plug the PB into the computer with the Desktop Manager running and when I did, it some how triggered the PB to show the Blackberry start-up screen followed by the desktop. I then heard to 2 beeps, I'm guessing to indicate it was low on power and then the screen went blank.

    I'm now trying the stack charge method you suggested, to see if it makes any difference, though again, I was under the impression if the battery icon and lighting bolt were to show on the display then it should be okay to leave it to charge.

    Hopefully I'm making progress.

    Cheers

    Let us know if it works...

    Also might consider that the battery is probable five years old.... depending on usage and the luck of the draw, it just might not hold a charge anymore.

    UPDATE:

    I did as you suggested and stack charged the PB per the info in the link you provided for 40 minutes, which is basically charge for a minute and then remove power for a second or two and repeat. I followed this the next day with an additional 30 minutes of stack charging, figuring this should have been more than adequate for the charging to start. Sad to say there was no change at all in the status when I tried charging it, I then remembered your comment about the batteries not being able to take a charge anymore due to their age. At this point I thought maybe the 1.8 amp charger I was using was faulty but, I charged a different device and it worked perfectly.

    I was about to toss it when I came across a You Tube video talking about "jump starting" the PB which involved opening the case and gently prying up the battery with a credit card. WoW was that ever a tough task, not sure what they use to glue down those batteries but, man does it ever stick. Once I had access to the under side of the battery I was able to access the battery terminals. From here I connected a multi-meter so I could see what the actual voltage was of the batteries and it showed as 2.547 volts, it didn't appear as though the stack charging had any effect. I then took a fully charged cell phone battery of the same voltage and connected it to the positive and negative terminals respectively along with having the multi-meter connected and it shot the voltage above 3.2 volts. Next I plugged in the 1.8 amp charger and saw the PB batteries begin to take a charge. After about 4 hours the batteries had reached 4.195 volts and an earlier video I had seen said 4.2 volts indicated a full charge.

    I removed all the wires, cell phone battery and multi-meter from the PB and flipped it over and low and behold the home screen was showing with the batteries showing they were 96% charged. I pushed the battery back down and reinstalled the back cover and its now working like a charm. I played around with it last night for some time and out checking different apps and the battery only dropped marginally. Before bed I plugged it back in and this morning it was back to being fully charged. Happy to say I now have a functioning PB again. Hope this helps some that may have a similar issue with their tablet. I'm not sure if posting the You Tube video I used is allowed but, if so, I can edit this post and include it.

    Cheers
