changing from charging in computer into data connection in computer

[Rick_Air]

A bit more detail is always helpful if you want some help in return.

But, if you're on a WP8 or above device when you plug it into a computer it automatically starts charging but will still show up as a removable drive.

Indeed it is not an android.
In the 930 there is in SETTING > USB > a box you can mark so you first will be asked if you want to make a data connection.

Furthermore check if your screen is not locked.
