xperia T cant switch on and can no longer be detected by PC Companion

My Xperia LT30p seemed to be good until i started to face problem with the battery. the sony mobile representative in South Africa said they do not have the battery for this model because the phone was shelved. then it would work but this other day i was trying to update it. after hours it just went blank, it could not be switched on, i try to force it but still it could not. i have tried to use the PC Companion to do repair but it now ca not even be detected. previously it would be detected. i wish sony could accept repairing it overhaul so that i can enjoy it.here in SA they say they cant.

I think in your Android version, you need to open Settings -> Bluetooth -> Tap on "Make phone visible" to be able to be paired or recieve from other bluetooth devices. If you already do this then you might try to backup your datat and perform a software repair using PC Companion.

The Xperia T was released on September 2012, almost 4 years ago, I still have one, I'm sorry to hear about your experience but there isn't much to suggest here other than to contact Sony directly >>> Local support with your feedback as this is a user based forum.
