It could be a ton of things.  Try these first:\n\nPop the battery out and plug in directly to the wall.  If it powers on, you have battery problems.  If not, jiggle the power cord in the back of the computer and keep pressing the power button.  If no luck, try doing the same while jiggling the cord to the wall or to the power brick.  You either have a bad motherboard or a bad power adapter.  Try another adapter if you can.  Is it on warranty? \n\nI just sent my laptop out yesterday with exactly the same problem...and it's either a fried motherboard or bad power adapter.

This can lead to two things.\n\n1.  Power supply is gone\n2.  BIOS is gone

Try turning on the monitor, see if it is plugged in right.  If none of that works don't hit it with a sludge hammer, bring it into a computer store.

Could be that it was jarred and an internal component is not seated properly.  If you are comfortable with doing so, you can try reseating the memory, hard drive, wifi card, etc... to see if that fixes the problem.  If you are not comfortable doing so, take it to someone who is.

If its the power adapter, why not replace it.  theres universal ones out there at most popular stores, and if you search the internet and hit the auction sites you should be able to find it relatively inexpensively.\n\nAs far as fixing the power adapter, Id try either doing a google search for fixing circuits, OR go down to the local bookstore and/or library and pick up a book that way.\n\nI dont know if Id be so bold as to try experimenting with the power adapter if I wasnt knowledgeable since a power fluctuation could do some serious damage throughout the laptop.\nThats up to you though

if it happened recently try system restoring it back to before it started. Click START - All Programs - Accessories - System Tools - System Restore. Then as i said restore it to the point at which you think it worked.

Check the power supply cable (the one with the 4 pins).  It sounds like it just isn't getting any power.  Even if there's something wrong with the jumper settings or the I/O interface, it should at least spin up.

This sounds like a plug got lose.  Unplug the power cord (and main battery if this is a laptop) then remove the plugs in the drive, and reinsert them.   Then apply power and see if the drive is restored.  \n\nThis is just a shot in the dark, but I have seen this situation on a rare basis. \n\nGood luck

Try shutting down, unplugging the keyboard, plugging it back in, and restarting. If that doesn't work make sure your "scroll lock" key is not on. If that doesn't do it you probably have a fried keyboard.

Go to a repair shop and fix it. Don't open the laptop yourself or you may end up with bigger problems

PSU failure, where the volatge exceeds ~8.5v. Check the keyboard connector to make sure it's clean.\n\nHave an experienced person look at it (don't pay to have it serviced until a friend says so, that's just stupid)\n\nUsually the fuse connected between the power and the keyboard connector would blow out before the keyboard would.

There should be a battery inside your computer that powers the BIOS. Try replacing it and see what happens.

There is obviously a short circuit somewhere inside the laptop. If it is that new, send it in for repair.

WIth a laptop, you would have to reset the CMOS which would involve taking the whole laptop apart and removing the battery. Best to take it to a shop for this.

How old is your laptop may I ask? Mine has done that a couple times after it comes out of stand-by, but it eventually turns on. Your hard drive isn't starting up, or there isn't any power getting to the hard drive.
