X-button bug on PSP

[Ponnypetra]

Hi!

 

I've got a problem with my x-button on my PSP. When the power cord is connected everything works fine, but when it's not: the X-button gos crazy, running round in menues, or giving full throttel in my games.

 

I don't belive the problem is mecanical, because when the powercord is connected to the PSP, but not to the wall outlet, the X-button still goes crazy!

 

I've tried to update to the firmware 3.52.. no help.

I've tried to reset the system to default... no help.

 

I've heard about others with the same problem.. but no solution...
