How To Stack Charge/Revive A Dead PlayBook=
here ya go:
1- plug the playbook charger, (stock, rapid travel, or dock), into a surge protector,,, surge protector should be off-
2- connect playbook-
3- turn on power using the surge protector on/off switch for 2 (two) minutes, then off for 1 (one) minute-
4- continue this as necessary until playbook begins to take charge normally,,, this will be indicated by a continuous flashing led light, (normally yellow to green)-
5- it's advisable to never let your playbook get below 10%,,, there is an audible warning sound that'll alert you to this-
6- if no surge protector is available, you'll have to remove the charger from the outlet as necessary,,, i don't recommend repeatedly removing the mini usb charger connection, as it's very fragile-
7- if possible leave it plugged in & charging overnight before stacking,,, this *may* shorten stack time...
hope this helps...
