Ok, anybody can help me? I emailed for this person above but i dont have any response.

I have questions.
Anybody know how is voltage on this 3 pin on right?



I found on this site another solution, but no work for me

Jump start a PlayBook a knottyrope tip - BlackBerry Support Community Forums

Ok, i found on internet information about this PIN.

Quote:
The center pin and pin closest to the cord is +12 VDC in reference to pin away from the cord. There would then be 0 VDC measured from the center pin to the pin closest to the cord.
And find image

THX for reply...but i have questions for specialist

I have in home HARD DISC USB charger. This charger has 5v and 2A

And my questions is. I can prepare microUSB and connect this charget to PlayBook microUSB with 5v 2A?

You know...i cut usb cable and add 5v and GND from HARD DISC charger and plug to microUSB in PlayBook

maybe this is way to alive playbook?

What do you think about this?

And, anywhere is schematics microUSB pin? I need to do this operation

Now i connect Playbook to microUSB cable to my laptop and Desktop manager show me this information:



When i see this information my playbook led still light in green color

I have used multimeter on PIN in cable flex, and show me on every three PIN 0v

0_o
Dont suggest this voltage information under...on 3 PIN i have 0v when led is green always

If your PB isnt in hardware damage, you can charge PB with 5V/2A USB power. When cut the micro-usb cable and sold it to Hard Disk Charger, you must short D+ and D- (white and green) together.
For checking battery voltage, u can use point beetwen batt-connector and 2 black IC (in your pic)
Sorry about my bad English.

I saw picture, and thought PB isnt charging ^^.
If you dont short D+ and D-, PB doesnt detect the micro usb cable as charger
PS: I have time but i dont have anything for edit picture. I'll try later if your PB still wont charge
