Check the ribbon cable (FPC) connecting the top panel to the motherboard. You may have not connected it properly, or it may have some damage to it. Look at the pic below. The cable I am talking about is labeled: "Switch Board FPC"

 

Yeaa i see some damage on the ribbon cable , but from where i can buy a new? Im in romania.. i was thinking to it too ,rly can be only the Ribbon cable? Because its too stupid issue

If you have a damaged pin, then it's probably the ribbon cable. Call Asus first and ask them if they sell these cables. Chances are, they sell the cable together with the entire board it attaches to. If they don't sell just the cable, you can find out the specs of the original and buy it from an electronics supplier or an e-bay seller like badatronix.

The specs that are important are:

1) Number of pins on the cable

2) Cable length in mm

3) Pin Pitch (distance in mm from one pin to the next)

4) Direction of pins (pins exposed on same side of cable vs opposite side (inverted))

5) Voltage, temperature and gauge specs. These numbers should be written on the original cable.
