It sounds like its a hardware problem. There are a couple of easier steps we can try before delving into the motherboard. It does help to have a set of smaller Philips head screw drivers for some of these steps. Lets work from easiest to hardest:
1.) Try taking out the battery and plugging the laptop into AC power. Power the computer on and see if it boots.
2.) If the above step did not resolve the problem, put the battery back in. Try removing the hard drive and booting. See if it makes it past the BIOS screen. If not, replace the hard drive and move on to step 3. (can explain how to take the hard drive out if you need)
3.) Remove the memory modules from the computer. There may be 2 under a panel on the back of the computer or one under the panel and one under the keyboard. Remove them 1 at a time and see how far you get into booting the computer up. (again, can explain how to do this if you need)
Report your findings back from those steps.
