slid button

my power/slid button will not slid all the way up please help

You mean it’s stuck and won’t let you turn the player on?

You do know there is a spring, and it doesn’t stay in the ON position, right?  If you slide it down to the HOLD position, it will stay there.

not it is not stuck it will not slid all the way up to turn it on. the only way I can turn it on is by my p/c and it will not turn off.

This is a mechanical fault; if you are within the warranty period, contact SanDisk for a replacement.
