Sai Ch Krishna,
Depending on the system. The bluetooth would have to have been purchased at point of sale. The wireless and the bluetooth are turned on by a wireless switch on the side of the computer. If needed you can reinstall the drivers. Also, make sure bluetooth is turned on in the bios. Below is more information.
Wireless Switch
Wireless Technology
The Latitude D630, D631, and D630c system ships with a wireless feature
called the wireless switch. It is located on the left side of the system next to
the IEEE 1394 connector. When used in combination with the Dell 38482;
Quickset utilities, this switch enables or disables the wireless LAN, wireless
WAN, and Bluetooth cards in the system or searches for all wireless networks in
range.
To scan for a Wi-Fi wireless LAN, slide and hold the switch in the
momentary position for a few seconds. The Wi-Fi Catcher network locator works whether the computer is turned on or off, in Hibernate
mode, or in Standby mode, as long as the switch is configured through QuickSet
or the BIOS to control Wi-Fi network connections.
Because the Wi-Fi Catcher network locator is disabled and not configured for
use when the computer is shipped, it must be enabled and configured through the
Dell QuickSet utilities to control Wi-Fi network connections.
Wireless Switch LED Settings
The LED on the wireless switch works even if the system is off. A user can
activate the switch and have it scan for networks without going through a
complete boot process. The switch can be set to detect for only certain wireless
signals, such as WLAN only, WWAN only, Bluetooth only, or any combination of
these. This is set in the BIOS under the
Wireless section.
The LED indicates the presence of a network as follows:
- Flashing green - The system is searching for a signal.
- Green - The system has detected a wireless signal and has
good strength.
- Yellow - The system has detected a wireless signal, but it
is moderate to weak in strength.
- Red - The system failed to detect a wireless signal, or the
wireless signal is extremely weak.
Thank You,

Suggest the computer - Doesn't start in good condition. It just seems that way. No Signal on the monitor, means the computer is Not sending a video signal. This is because the computer isn't working. Could be due to something as simple as one, or more, Ram Memory modules are loose, and not fully seated in the ram slot. I'm willing to bet it's a bad power supply. Has a weak voltage power rail. Enough power to light light's, maybe spin fans, but not enough to turn the Processor on. 1) ALL the lights use less than 1 Watt of power. 2) EACH fan uses 2 to 3 Watts. 3) A typical Processor uses 51 to 125 Watts. Depends on what processor it is. On the harddrive is a boot sector. The processor must be running in order to find, and implement the boot sector. Otherwise the harddrive just sits there, and spins. Makes it sound as though the harddrive is operating, but it's not. (Inside the harddrive are Platters. They resemble CD disks. These are what is spinning inside the harddrive. More info on this,http://computer.howstuffworks.com/hard-d... ) This is Dell Support, and the User Manual page for the Optiplex 755 series. Click on which style of Optiplex 755 you have,(http://support.dell.com/support/edocs/sy... ) I chose Desktop for an example. In the left column of the list click on - Troubleshooting. Now click on - Power Lights.
