Q5 is not starting/booting up. Tried all the solutions. Any suggestion?

Question

Hello,
Around after two-three minutes, from when the battery of my Q5 was remaining around 2 percent, the device restarted automatically while I was typing an email.
While it was rebooting, I plugged in the charger. But somehow there was an infinite loop of rebooting process. The device was rebooting itself as soon as it was started. This happened for three times (three reboots). So while it was booting up for the third time, I unplugged the charger. This time it started normally. I waited for few moments, everything seemed OK, so I plugged it again. It re-started itself after I plugged it in, and started the loop again.
So I removed the charger. I was busy at the moment, but after 15-20 minutes, when I looked at the device, it was turned off. I don’t know why it was turned off though. I mean, whether cuz the battery was drained or cuz of some other reason.
Then I connected it to the charger, but the orange LED didn’t turn up. I waited for few (clock) minutes, no response from LED. I tried to turn on the device by pressing the power key, no response.
Then I turned on the laptop with MS Windows/Link on it, while device was still connected. Windows did not show any sign of a USB device being connected to the laptop. I opened up Link, I tried to reload the software. No luck there as the device can’t be reset as required by Link.
So, I checked if the USB cable was working, by connecting my Bold. I checked my Q5’s charger by connecting Bold to it. Everything was OK.
Then I searched online, and found these/threads solutions:

What I’ve done so far (before posting here):
•    Checked the working state of charger/cable, and plugged it in the outlet (wall, not computer).
•    Left the device charging for almost three hours (no any activity from LED during this period)
•    After three hours, tried to start the device in usual manner. Held the power key for almost 20 seconds, no reaction from device/LED.
•    Pressed both the volume keys simultaneously for almost 30 seconds. No response.
•    Tried the last two steps again after disconnecting the device from charger.
Further details:
•    All the installed apps, are installed from the BlackBerry World itself. No other apps were installed, not even .apk s.
•    No media is stored on device memory, I keep everything on MMC. In total, usually 20 megabytes of the device memory is occupied by “user files”. These files contains only pdf, word, and .txt files.
•    At any given moment (at least in last two months), almost 50% of the device memory is free.
I am not sure what the exact problem is. I mean, whether it is hardware or software malfunction. As I’m in India, usually after 20 minutes of charging backside of the device gets a little warm. Today, even after 3 hours of charging, the device is cold.
I do not have any problem to wipe the device clean/reloading the software. I’ve everything backed up; and I use enterprise on other BB device. All I want to do is to get the device started in any way, as soon as possible.
Please help folks!!
Thanks a lot in advance,
Best Regards,

You've done a pretty thorough job of troubleshooting. At this point I'd say it's time to contact your provider and get a warranty exchange (if it's less than a year old.)
