How do i turn on the wireless and bluetooth on my dell latitude e5400?

You should be able to turn both of these on using one of your function keys, and the number keys across the top. The wireless symbol should be F5 (it is on my laptop) so hold function (bottom left key) and hit F5, that should start your wireless.

My Dell Latitude D630 will power on but the screen is black....nothing will show not even the startup page for windows. What do you think the problem may be

I would suspect either the video card or your LCD screen.. A good test is to hook up an external monitor and see if that works. Be aware that when you start it up, you will have to hit the function key and special function key combo to switch it to the external display.
On the latitude, that is the Fn key plus the F8 key.
