My Blackberry Bold won’t turn on!

While I was in my parents’ house at Nishinomiya the battery of my Blackberry Bold I carried with me was too low to turn on the phone. Then after returning home at Tokyo I plugged the charger in it to recharge it, but it didn’t turn on even if I pressed the end (red) button of it.
Solution: (1) Pull out the battery of the BB; (2) Plug the charger into the BB with its battery out; (3) If the LED turns red then put the battery into the BB again; (4) Wait until it restarts.
