Can't Charge!! Here's the deal: One good day, my T610 stopped chargin' I didn't knew what the problem was, so I figured that the dust/dirt accumulated on the AC adaptor's entrance would be the problem, so I've cleaned it up nice and carefully (I didn't wanted to brick it up) and it turns out that after that, it charged again, It kept chargin' for months until yesterday, I figured that the same problem came back again, so I've cleaned it up again nice and carefully, but now It's not charging anymore!!! Charged a little and then Nothing! What this problem could be?? I definetly doubt that my battery has died, 'cause like I've said before, it started to charge previously and then It died slowly... Oh! By the way, when I plug the charger a red light turns on in the center of the phone, but the screen "charging" does not appear, and the charger keeps emitting this barely ear-receptive buzzing noise, it's a very poor buzzing noise, but I've just heard it today... hope you can help me! Thanx a lot.
