Macbook pro Keyboard Backlight won’t turn on.

A light intensity sensor near FaceTime HD camera is the answer to this problem. Apple has done some intelligent work to associate Keyboard Backlight and Screen brightness with environment light intensity. It sure has to be this way in order to give marvalous 7 hr battery backup.
If in bright day light you press F6 you get no response, but as soon as you keep hand near to camera you’ll see F5 and F6 functioning.
Hope this helps!

MKV playback on Samsung LED TV.

I have a 32 inch series 5 LED smart TV UA32D5900VR. Before buying I did complete research about the playback capabilities and Samsung came out to be winner but, when now during its actual usage I found the following missing capability.
It does not play MKV files through network.
I found solution for all the samsung LED TV’s and its just a simple trick of renaming mkv to avi file.
Thats it!
