If the Vostro doesn't read the signal automatically try to switch the signal from internal to external using the Fn (function) key + one of the F keys above the number keys. This key is usually F4 but may be different for yours. Also, make sure the input is correct on the tv....

SOURCE: I forget my Dell Vostro
Bios passwords are very difficult to bypass
you could try to remove the cmos battery and leave it out for an hour before putting it back in
sometimes this may work if you havent got a manual to show where the cmos battery is you can download one from this link www.dell.com go to support/downloads and search for the manual
also i found this link on the net you may find it interesting
if the link don't work then copy it and paste it into your search engine
also found this it makes good reading
HOW TO REMOVE THE CMOS / BIOS
PASSWORD WITHOUT DOWNLOADING Any SOFTWARE
THIS IS ONE OF
THE MECHANICAL METHODS THAT QUITE OFTEN WORKS
1 . CHEK OUT & SEE WHERE IS YOUR CMOS BATTERY LOCATED .
2 . TAKE OUT THAT CMOS BATTERY AND LEAV IT OUT FOR 30-40 MINS .
3 . NOW PLUG IT BACK IN AND RESTART HOPEFULLY IT HAS WORKED
IF THIS Did NOT WORK Try This Method
1 . THERE IS ONE JUMPER LOCATED ( near SATA hard disk slots mostly )
2 . jumper slot is of 3 pins , out of which , jumper is put into 2 pins
3 . remove the jumper & put into other 2 slots ( center one & the left or right which was not plugged into previously )
4 . start PC & u should go into bios settings without requiring the password .
5 . And there u can even change the password of bios settings .
6 . now it will ask u to put the jumper in its original position . put it there & restart
I have heard of people trying this a no of times & it seems to work
please let us know if any of these methods worked
