Palm 755p Problem With Buttons Mapping

[parrotred]

I am having palm 755p of late i am facing problem with buttons on the phone.
When i press
phone button it functions like the (up arrow)
calendar button it function like (down arrow)
menu button on bottom right near alt it functions like (right arrow)
left arrow button it functions like power button
side single button it reduces volume
bottom button reduces volume
top button switches back to the last software
when i press center button it functions like message

The phone autmoatically sleeps off and when i try to awake it with the phone, calendar, message and power button it does not activate the phone. Instead i either remove the battery or eject or insert the memory card to activate the phone. Although the phone is on.

I have hard reset this phone also.

Please help this is a strange problem.
