Is the laptop running hot? Sometimes the power saving mode in the BIOS will shut off the fan to conserve power when the processor isn't in danger of overheating. Try getting into the BIOS and playing with the fan and power saving settings to verify that the fan actually works as installed in your system. Otherwise, if you know that the fan works and you have it plugged into the system board correctly, there must be an electrical malfunction internally on the laptop and there is no way to troubleshoot further unless you know a lot about circuitry.

Look for a switch that turns on the wireless device. Also check in the connection manager if the device is active and the wireless adapter is within range.
SOURCE: Can I connect my dell latitude d360 laptop to my tv?
you need to have the same connections on both my laptop has svideo or vga connector, some have Hdmi which is the newest, but the tv and laptop have to bot have the same connectors, it may be a dvi, or any that I mentioned, then you need a cable for your video, and another for your audio, both the audio and video cables are run to the tv, the only one that has both audio and video is the HDMI which tv's from the last hear or 2 usually do have. Then depending which input the laptop is using which it will tell you where the connection for the tv is, you set it to that input and that turns your tv into a giant monitor

SOURCE: FORGOT BIOS PASSWORD DELL LATITUDE E6400
The above solution does not work on an E6400. Any fix regarding removal of battery, shorting pins together, etc does not work. However, what does work is to use the Dell Asset/Service Tag BIOS Reset Tool that is available on Torrent Sites. Boot the CD image and when you are asked if you want to delete/change the service tag select "Y". When asked for the new service tag number re-enter your current service tag. Then the tools erases the BIOS and inputs the new service tag. A by-product of this process is that the BIOS master password is removed from the BIOS.
