Can you choose fullscreen resolution instead of blank space ? Did you do so ?
Try changing to dirext11 and see if that changes anything.
If you get same speed with HLE and LLE it means your are beeing bottlenecked by your graphic card.
Something is wrong with it, since 650m is decent card and you should be seeing difference between HLE and LLE.
Maybe somehow you are using intel integrated graphic instead of 650m ( even though its written in dolphin that it uses 650m )
Disable integrated graphic in bios completely, just to be sure you are not using that.
Did you try running something alse on your laptop, such as demanding pc game, to see everything is ok with it ?
