Some questions if I may;
Does the notebook normally emit a single beep when it boots up.
Does the notebook screen stay lit or turn black.
When you tried the external screen did you try toggling the display from the notebook to the external screen by pressing the Fn and one of the F1 to F12 keys (Fn + F5 is quite common).
Had you made any hardware or software changes previous to this happening.
Does the hard drive activity LED blink at all.
Had the notebook been dropped or banged previous to this happening.

Please answer the above that I also asked.
The hard drive light does come on but only for about 10 seconds.
Too early to be sure but this could point to a bad HDD, you would however normally get a boot failure message.
One thing I forgot to mention...it won't stay on when unplugged from power source.
The battery is bad so I suggest that you remove it so that it does not hinder your troubleshooting.
You are welcome btw

Did you hold down the Fn and F8 key to toggle between displays.
Have you removed the battery.
With the battery removed and the AC adaptor disconnected, remove the memory module/s then hold down the power on button for between 20 and 30 seconds, replace the memory (only one stick if you have two) connect only the AC adapter, power on the notebook and let us know the outcome.
To help with removing and replacing the Ram read your user manual which is available here

I toggled with F8. I took out the battery and memory and held the power on button. Same results. Again thank you for your help.
Not being pedantic but did you then replace the memory and attempt to boot.

Remove all memory and then power up the computer to see if the results are the same.

If you do not get at least a BIOS or the Dell logo splash screen it is a hardware and not software problem, the two most likely culprits are the integrated video chip or the CPU, the video chip if bad is not normally a cost effective repair as it requires the services of an appropriate tech who has the knowledge and equipment to test, remove and then resolder a new video chip in place, this effectively writes off the MB as a replacement board is most often less expensive than the replacement of the GPU.
