Try Re-seating the RAM. This mostly does the trick.... does it beep any error sounds?

If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.
Ensure that the voltage selection switch is set to match the AC power at your location, if applicable.
Ensure that the processor power cable is securely connected to the system board.
This can be caused bya defective power supply or a defective motherboard. Just to make sure thatnothing else is causing the problem, remove any PCI cards like modem, videocard, sound card, etc... Remove the memory modules and disconnect cables toCD/DVD drives. Look at the USB ports to see if any are damaged.

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

Test all power and data leads that attach to your hard drive IDE,SATA
the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty
if its a 40 pin flat ribbon type it will be the first to fail
make sure all leads that are attached to your drives dvd\cd and floppy have secure connections and are not faulty
even something as small as a faulty electrical fan and its lead can cause you problems
computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error
Check your RAM.
The RAM is located in the middle of the motherboard.
There are tabs that you can push to release the RAM.
Remove it and put it back in place until the tabs pop out.
Loose RAM can cause your computer not to start properly where you want to see a video signal.
Remove the memory modules from their slots.
Take the opportunity to clean the slots on the motherboards and the memory module connectors.
Use compressed air to blow dust away and clean contacts with a soft cloth.
Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components.
Do not use solvent that may attract dust and never poke things like cotton buds in to slots.
lightly rub an alcohol (Methylated Spirits) on a cloth not to hard let the alcohol do the work on the copper gold or silver tabs and r
Allow the pins to dry.
They will air dry in a matter of minutes.
When
you plug in the power cord is there any lights whatsoever on the computer?
When you press the power button do you hear fans running, hard drive spinning,
lights on the computer, hear any beeps or lights constantly blinking, hear the
DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a
second or two? If so the laptop is trying to boot or may have booted, but
the screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with the computer
and why it is not booting. Most times it's a motherboard issue when you
hear beeps or blinking lights continuous. Most times the problem is with
the memory or Video Card. Count the Blinking Lights or Beeps and take note of
their pattern (1 Long or 1 Long followed by 2 Short).
Maybe your power cord is bad if you don't get anything to happen whatsoever
when you press the power button.
Maybe
you have a Static Charge Buildup. Remove the Power Cord, then Press and
Hold the power button for 30 seconds. After 30 seconds plug the power
cord back in and hit the power button to see if it boots.
Maybe
your memory is bad or the memory slot is bad.
Remove
the Power Cord, Open the Case and remove one of the memory chips. Set the
chip aside then try rebooting the computer. If it boots, then you know
the memory chip you set aside is bad so mark an x on it with an ink pen.
If it fails to boot then move the chip to the next memory slot and try
rebooting. If it fails take the chip out and set it aside, then put the
other chip in and try booting it in both slots. If it boots, just to
verify that the chip set aside is bad, mark an x on it and put it into the open
memory chip slot and try booting.
Maybe
your power supply is bad. Sometimes there is enough power to make the
power light or some other lights come on but not enough power to make the fan
turn on or hard drive spin.
Below are links and info I found from Dell's Website based on your model.
