[HELP] BlackBerry PlayBook DEAD ( now he turns on but doesnt charge ) HELP PLEASE

as topic says, my playbook was dead. so i did the trick of put the charger in so many times and he woke up. but when he woke up was connect on USB and showed an update and i clicked YES,

now it says

critically low battery level. connect your tablet to a power source. the software update will resume when the battery level is above 20%

and i read this somewhere: " it will not charge unless the OS is booted, but will not boot unless charged " ???????????????
what can i do? can RESET THE SOFTWARE with the buttons?

EDIT:
i turned OFF and i can see the display on, but black, and the comes a light green and goes slowly. i will sleep not is 1am in Portugal. i hope this thing work tomorrow morning!!! :(
any suggestion will be very much appreciated!!!

Plug in the regular ac adapter and leave it alone (which you may be doing if you've gone to sleep.

Solved. It was sying 0% i turned off pressing the power 2seconds untill appears the shutdown menu. Then he charged turned off. Its ok now

Good to hear that it is working.

Now is my cousin's playbook. doesnt turn on. i tried a lot of things. now he turns on with all letters and after all colours he just turns off...

Debrick, again:

Try the Debrick method....

Perform a backup of your pb if you can using Desktop Manager or, at least, manually coping any unique data, photos, voice recordings, documents, etc.

1) Turn your playbook OFF by holding down the power button
2) Let your playbook sit for about 10 minutes as earlier suggested.
3) After letting the PB sit (and still powered off) open up the Blackberry Desktop Software (the latest version)
4) Once the Blackberry Desktop Software is opened, use the USB Cable and hook the PB to the PC.. THEN power on the Playbook
5) A screen will show on your computer showing that the device cannot be found
6) Click on Update. It will take awhile

I did it but after desktop manager says "installed" it says " connecting to device, it may take a few minutes"... and nothing happens... after 15 minutes it says " cannot connect to device, a password may be needed" and the device is off... :(

I don't know if there's a support number for your country:

The PB has a one year warranty to the original purchaser. It also has 90 free Tech support. I do not know how Rim deals with "quasi-tech support v. warranty"
