Take it to a repair shop. There are endless reasons why it doesn't work.

Had the same problem with an HP Pavilion PC. Called tech support and they resolved the issue. They had me unplug everything to the machine, including the power cable. Then, I had to hold down the power button for 30 seconds. Apparently, this drains all power that is stored and rests something. I thought the guy was just following his checklist, but you can imagine how surprised I was when my computer booted up.

Thank you KEVDMD (above) for your thoughtful consideration in writing your post.

I was installing new memory (in Gateway PC) and thought the computer was shut down when it was actually in hibernation mode. I shut down when I was done and couldn't boot back up. Fan's were running and power was on, but nothing else.

Based on a few Google searches and subsequent forum discussions I came to the conclusion that I needed to reset the motherboard/bios via the pull battery method.

UNTIL I read kevdmd's post above.

Instead, I decided to pull the power chord in the back and drain all juice to the motherboard. After, I booted up and heard 3 beeps. Now i'm getting somewhere! I shut down again and ...VOILA! I couldn't be happier to hear Vista's startup theme!

Hope this helps anyone else with the same issue.

Cheers!

Hello! I am also having problems with my Laptop, which is a ASUS M51S. First when I got this problem, that the laptop wouldnt start up, and the lights were there for a few quickly seconds, I was trying abit on my own. Took out the battery and power supply, and inplugged both of them again to try if it worked. Sometimes it did, but most of the time it didnt work. When I saw this topic, I followed the instructions, and after a few tries it worked. Im too afraid to not getting my laptop to start again, so last time I have putted my laptop to "rest-mode". Im sitting here trying to start up the computer now, and I can't get it to start, and I've tried many times. Is there any other ways to start it up? What can be wrong? I dont really have any money at the moment, and Im addicent to my laptop, and using it lot each day, so I do not want to went any money on new computer or repair (unless its the only way).
Please, I need help!
