The problem with charging stems from the way the internal charger has been designed. The way RIM designed their charger is it needs a small amount of battery power to run its micro-controller for the charger management. They did not design a fail-safe bypass charging circuit that is not dependent on the state of the battery, where it can put a basic required amount of start current directly to the battery to get the process going. Normally all chargeable type systems are designed with a battery fail-safe system in case the battery goes flat.
When doing the so-called stack process, you are causing a trigger affect through the circuits to give a sort of pulse to the battery before the management circuits kick in. Doing this process over and over again is eventually allowing enough charge to the battery to get the charger management working properly.
I have no idea why anyone would design a charger type circuit where if the battery goes too flat, it is almost impossible to charge it. This is a bad design as far as I am concerned.
When my first Playbook was new out of the box for some reason it was too dead to make it work. I had to mess around with the stack charge idea for a number of hours just to start. I almost returned it. I have it a year now, and as far as what it does for me I am very satisfied with it. I own a number of these tablets now. They are of very good quality except for the few bugs here and there, and also the charging issue.
If I had an engineer working for me who design a battery charge system that worked like in the Playbook, he'd be out on his bottom-side very quickly. This makes no sense at all.

Insane Example:
This is something like designing a great car, but if it runs completely out of gas the fuel cap will not come off to allow the user to re-fuel it. This is because the engine has to be running to remove the fuel cap. So, the user has to somehow try to put the fuel directly in to the gas lines in order to get the engine running enough to allow the fuel cap to be removed.
Comment:
I like the Blackberry phone and Playbook a lot. I am due for a phone upgrade. I find the delay of the BB10 sort of annoying. I wanted to upgrade four BB phones this year, and buy another two PB tablets. I have no idea about what I am going to do if any of the phones were to go defective. I also don't want to invest a large amount of money in to the phones with older technology, and also have the risk if BB is not around much longer to support these products!

07-17-12 10:17 AM - I'm not an engineer but I really think the "FLATLINE" behavior of the pb is really stupid. Unless there is an exceptional reason why they made it impossible, well, not impossible but ridiculously hard, I don't understand it. It should not need major Jump Starting as it does now.The problem with charging stems from the way the internal charger has been designed.
