Hi, Try do a CMOS reset on the motherboard. Remove the Lithium memory back-*up battery and let it sit for a while. If still a no go, borrow/replace the memory, checkif the CPU shows sign of warming up when powered on (this would indicate that it is indeed receiving power but just not booting). Try reseatting the video card if you've got one. Another that you can check is if the capacitors very near the top of the CPU are busted/swollen. Normally they should be shiny and flat with an X or Y mark. If they show signs of brownish color, cracked X or Y, blistering, swollen/bursted top, then you have a major motherboard problem which would require replacement. Hope this be of some help/idea. Post back how things turn up or should you need further information. Good luck and kind regards.

Tips for a great answer:
When you plug in the power cord is there any lights
whatsoever on the laptop, where the plug goes in or on the AC Adapter of the
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 laptop 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. And if that's true maybe you was operating off the battery the last time you had it on and since the power cord is bad, it was not charging the battery so the battery is drained and the power cord is bad.
Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove the Battery, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in (leave the battery out) and hit the power button to see if it boots. If it does, you can put the battery back in and let it charge.
Maybe your DC Power Jack which is where the power cord plugs
into the computer is bad. Take an ink pen and push the tip inside the
jack and see if the little pin wiggles, if so the jack is bad. You'll have to
take the laptop apart to fix it. Most times it is soldered onto the
motherboard, so you will have to desolder the old and solder a new one.
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.
