Directly am going to solution....

Do you see the red marks in the picture.....And the solution
1.Do you see a free led near that blue cover
2.That blue cover can remove -you have to remove it
3.Then plug it on the free led that you see first.
4.There is total 3 leds that blue cover can hide two leds so plug the led in free led and centre led
5.Do this on that two areas.....
TO CONFIRM THE AREA ALWAYS CHECK THE TEXT PRINTED ON BOARD...(USBPW-..)
If your problem doesn't solve please inform me..Thank you
