So I guess you may try flashing the appropriate RUU (to restore the stock software as possible) and asking service center to replace the faulty button. And you may ask if this will cost you in advance. =)
Edit: and could you please share your experience if you will try.
Thanks for your reply, I will try it tomorrow and ask the service center about it and will report back surely.
Edit: I got it repaired from HTC, although the service guy was a fool, he just repaired the phone and gave it back, didn't even check bootloader or anything, feels good to have my power button back
