PowerShot SX40HS will not power on

[PatH]

PowerShot SX40HS will not power on.  

Received message "SD card is locked."

Removed SD card; unlocked it, returned it to camera.

Turned on camera.

Lens extened, then camera shut off. 

Removed battery. Recharged it.  

Camera still will not power on.

Any ideas? All help is appreciated.
