I purchased this device (Asus 6z) three years ago. I am looking forward to use this device for sustained time. But due to heavy use battery life has gone down and power button has also became loose. In simple words I want to refurbish this device and continue to use same. Is this thread is still seen by mods help me to get glimpse of cost for same and locate nearest authorised service centre (Navi Mumbai, India). All help will be appreciated.
