Follow these steps to determine why your computer won't turn on.

  1. Computer shows no sign of power at all.Try these steps if your computer will not turn on and is showing nosign at all of receiving power - no fans running and no lights on thecomputer case.
    Important: You may or may not see a light on the back of your PC depending on the kind of power supply you have and the exact cause of the problem.
    Note: Don't worry about the monitoryet. If the computer is not turning on because of a power issue thenthe monitor certainly can't display anything from the computer. Yourmonitor light will likely be amber/yellow if your computer has stoppedsending information to it.

  3. Computer turns on for a few seconds and then turns off. Follow these steps if, when you turn your computer on, it promptly powers back off.
    You'll probably hear the fans inside your computer turn on, see thelights on the front of your computer turn on or flash, and then it willall stop - always before the boot process is complete. You may or maynot also hear beeping coming from inside your PC.
    Note: As in the previous scenario, don't worry about whatstate your monitor is in. You may have a monitor issue as well but it'snot possible to troubleshoot it quite yet.

  5. Computer turns on but nothing shows on screen.If your computer seems to be receiving power after turning it on butyou don't see anything on your monitor, try these troubleshooting steps.
    In these situations, the power lights will stay on, you'll likelyhear the fans inside your PC running, and you may or may not hear oneor more beeps coming from the computer.
    This situation is probably the most common in my experience workingwith computers that won't start. Unfortunately it's also one of themost difficult to troubleshoot.

  7. Computer turns on but stops booting during the POST.Use this guide when your computer powers on, shows at least someinformation on the monitor, but then stops for any reason during the Power On Self Test.
    Use this troubleshooting guide primarily if you receive a BIOS errormessage during the POST but also if your PC locks up during the POSTwithout an on-screen message.
    Important: If you're having an issue during the loading of the operating system, which occurs after the Power On Self Test is complete, see Step 6.
  8. \015\012
  9. Computer turns on but an error message prevents the operating system from loading completely. If your computer begins to load Windows but then stops booting and displays an error message, you're best bet is to troubleshoot the problem based on the specific error message.

With the little bit of information presented, it appears that this is possible a power supply problem. One thing you can try is to unplug the power adapter from the laptop, remove the battery, then plug the power adapter back into the laptop. Then try to turn it on. If everything comes up normally, then the problem points, potentially, to the battery.\015\012
