sleep + volume + mute button stopped working

Hi

after getting my bold 9900, it shipped with an older OS. I installed .585 and everything worked fine. After 2 weeks, the phone fell from a height less then a meter away, between the couches. I think it fell on the metal bezel. I used it normally after that, but I did not use the sleep or volume or mute buttons. Later at night when i tried using them, they werent working. I thought maybe it was a software problem. So I tried the newer OS ( .590 ), i tried the os it shipped with ( .24x ). Nothing helped. I did fresh installs, without any apps installed or anything. Could I conclude its hardware problem ? It's under warranty, so after I get help from you guys I will call Rogers. Thanks for any ideas.

Sounds like something got damaged in your device's sudden stop on the floor behind the couch. If a new OS did not fix the problem, I, too, bet it is a hardware problem. Unless you want to take it apart (not suggested), you need to get it replaced or repaired. I would keep mum:eek: about the fall!
