HTC Amaze solid amber - orange - red light - won't turn on

Just wanted to post about a power-on issue I had with my HTC Amaze 4G from Telus (same model as T-Mobile, and similar hard-ware to the Telus SII X (same cpu)).

Scenario: I forgot to plug my HTC Amaze in before falling asleep. In the morning when I woke up, it was at 9% battery. Since I didn't need it right away, I thought I would just shut it down, and plug it in later to charge it up and continue using it. I tried to do just that... I pressed the power button until I got the menu that offered "shutdown" .. I chose that, and thought it was shutting down. I wasn't able to get it to power up later, and during some of my troubleshooting, I saw a recovery screen (but no backlight.. I barely noticed it because of the backlight not being on), which I used the volume up/down buttons to select shutdown from the menu and power button to select/press enter on the selection. After this moment, I never saw anything on the screen of the Amaze, no buzz, no backlight, no recovery without backlight or otherwise. I tried different Key combinations such as volume down + power button, then I tried volume up + power button... all with no result.

Long story short: I had been trying to plug it in all day to charge using a usb cable plugged into a computer. This did not work to recover the battery from its discharged power state. I finally rectified the situation when I went to bed again (and decided to try fiddling with it again before taking it in for warranty), and it ended up finally "charging" when I plugged it into the HTC provided wall charger. I later read online that USB cables plugged into computers or other "small" power sources (I'm assuming 5 volts and 500mah) that it just "trickle charges" (according to another HTC manual for another similar phone). The HTC wall charger has a higher output (don't have it here right now to check if it outputs higher volts, or just higher amps, or both). Once I finally got the charging light to be on solid amber / orange, I was able to turn on my HTC Amaze 4G without any problems like usual. When I finally got booted up again, it showed the battery charging, and only had a 4% charge at the time.

I'm assuming that when I chose "shutdown", it either failed to shutdown, or HTC's (proprietary?) feature of providing for faster boots by doing something that seems closely related to a "suspend", and ran the battery right dead, and the usb cable plugged into my computer, and into my cigarrette lighter was unable to actually charge the battery up in order to turn it on again... only using HTC's wall charger did it get enough juice to bring the battery back to life.
