    if (!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setMessage(R.string.gps_disabled_message)
        .setCancelable(false)
        .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                    Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                    startActivity(intent);                  
            }
        })
        .setNegativeButton("No", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                dialog.cancel();
            }
        });
        AlertDialog alert = builder.create();
        alert.show();
    }

This creates an alert and allows the user to go to the settings screen and hit the back button to come right back to your app. The power widget exploit doesn't work beyond 2.3 to my knowledge.
