This is more than likely a voltage problem:

If Compaq: Hold the Fn + F10 or F11 while hitting the startup key.
If Dell: hold Ctrl+ Windows Logo Key.

hope this helps.

Computer will not turn on even with power cord


1. Disconnect any devices connected to the computer including printers, hubs, and third-party keyboards or mice, and test the computer again by trying to turn it on.
2. Find out whether the battery on your Apple portable has power. Press the small button on the side or bottom of the computer, depending on the model. Lights should indicate the battery's level of charge. A single blinking light means the battery needs to be recharged. Connect the adapter to recharge the battery.
3. Unplug the power adapter from the electrical outlet and from the MacBook Pro. Wait one minute. Plug it back into the wall first, then to the computer. Make sure the electrical outlet is working by plugging in another device (such as a lamp). When you plug the adapter back into the computer, the power adapter LED should light up green or amber. If the light does not come on or the computer continues to not power on, proceed to step four.
4. Inspect your MagSafe power adapter. See Apple Portables: Troubleshooting MagSafe adapters for instructions on cleaning the adapter and more details for these steps:
  • Check the MagSafe connector on the adapter for any bent or damaged pins, debris, or alignment issues with the connector.
  • Check the MagSafe connector on the computer for any debris, damaged pins, or alignment issues.
  • Check the MagSafe adapters cabling for any wear or cable issues.
5. Make sure you are using the adapter that was designed for your computer. If you aren't sure or if you need a different adapter, learn which adapter is appropriate for your computer.
6. Review the steps for resetting the SMC (System Management Controller) on your Apple portable computer.
7. If you recently installed additional memory or a hard drive not made by Apple, make sure it is installed correctly and is compatible with your computer.
8. If you are still unable to start up your computer after trying each of these steps, schedule a service appointment with an Apple Retail Store or an Apple Authorized Service Provider.

Hi,

Follow the steps below and it should solve your mac problem..

  1. Disconnect any devices connected to the computer including printers, hubs, and third-party keyboards or mice, and test the computer again by trying to turn it on.
  2. If you're using a MacBook or MacBook Pro, check the battery level. Press the small button on the battery or on the side of the computer. You should see lights indicating the battery's level of charge. If you see just one light blinking, the battery needs to be recharged. Use the fluorescent pen computer with the adapter connected to recharge the battery.
  3. Unplug the power adapter from the electrical outlet and from the MacBook, MacBook Air, or MacBook Pro. Wait one minute. Plug it back into the wall first, then to the computer. Make sure the electrical outlet is working by plugging in another device (such as a lamp). When you plug the adapter back into the computer, the PowerBook G4 Battery 15" power adapter LEDs should light up green or amber.
  4. Inspect the MagSafe port on the computer for debris, such as metal stuck to the magnet in the port, which might prevent the connector from seating properly. On the adapter side, look at the DC connector for dust or other debris and check whether pins are missing, bent, or stuck down. If you find any of these to be true, see Apple Portables: Troubleshooting MagSafe adapters for instructions on cleaning the adapter.
  5. Make sure you are using the adapter that was designed for your computer. If you aren't sure or if you need a new adapter,learn which adapter is appropriate for your computer.
  6. Press the control key, the command key, and the sony vgp-bps13a/b battery power button simultaneously and hold for three seconds to try to restart the computer.
  7. Reset the PRAM. After pressing the power button, hold down these keys simultaneously: Command-Option-P-R, until you hear the startup chime at least one additional time after the initial startup chime.
  8. Reset the SMC for the MacBook And MacBook Pro by removing the AC power, removing the sony vgp-bps13 battery and then holding down the power button for five seconds. On the MacBook Air, press (left) Shift-Control-Option along with the power button once. Note: You must use the keys on the left side of the MacBook Air keyboard.
  9. If you recently installed additional memory, make sure it is correctly installed and is compatible with your computer. Remove the new memory to see if the computer starts up properly without it.
  10. If you are still unable to start up your computer after trying each of these steps, schedule a service appointment with either an Apple Retail Store or an Apple Authorized Service Provider.
Regards,
Ron

Power only stays on when plugged in.


It sounds like you have a defective battery. Batteries, even rechargeable ones, aren't made to last forever, so depending on how often it is used and charged, it is very possible that it is dead. If not, you could have a bad connection between the battery and the computer. The best thing to do would be to take it to an apple store or mail it in to apple.

  9. If you recently installed additional memory, make sure it is correctly installed and is compatible with your computer. Remove the new memory to see if the computer starts up properly without it.
Also:
The MacBook SMC Firmware Update v1.1 improves the MacBook's internal monitoring system and addresses issues with unexpected shutdowns. This update is recommended for all MacBook systems, including those that received warranty repair.
You can use the Software Update feature of System Preferences, or download the MacBook SMC Firmware Update v1.1 from Apple Software Downloads.
Note: If your MacBook is running Mac OS X 10.4.6, you won't be able to see the SMC Update until you update to Mac OS X 10.4.8. Once you have updated your system software, the SMC Update will appear as an option in Software Updates.
MacBooks running Mac OS X 10.4.7 will be able to download and install the SMC Update, so it is not essential that you update your system software, although Apple always recommends updating to the latest version of the system software.
If your MacBook is in a state where it will not remain on long enough to install the update, wait for the issue to reproduce itself. Once the MacBook has turned itself off, turn the computer on by holding the power button down. Keep the button down until you hear a single long tone. Once you hear the tone you can release the button, install the recommended updates, and restart normally.

Charging does not charge


If your Notebook computer battery is not charging, try the following:
  • Reset your computer's power manager. For information on how to do this with your specific model, search Apple Support.

    • Make sure your AC adapter is properly inserted into your laptop.

    • Connect your computer to its AC adapter, shut it down, and then let it charge overnight. If it does not charge, it's likely you have a hardware fault in your computer, battery, or adapter, and you should have it repaired.

    • Test your AC outlet. See if your battery will charge if you plug it into a different outlet, or see if another electrical device will work in your original outlet.

    • Test your AC adapter. Try connecting a different AC adapter to your computer and see if it recharges.

    • If it's removable, test your battery. Try using a different battery with your computer and see if it will recharge.

    • In some of the early PowerBooks, the battery will not charge unless the computer is turned on. If you have an old PowerBook and your battery isn't charging while it's turned off, power it on, put it to sleep, and then see if it recharges.
    If you go through all of these steps and your battery still won't charge, or you can't narrow down the source of the problem, you will probably need to have your computer repaired. However, it may be worth your time to consult Apple Support first. It contains entries on problems with specific computer models and versions of the operating system, including battery recharge issues.

My daughter says her built in Isight camera is only showing black. This happened one time before and I found a fix online that was a couple of keystrokes but cant find it now...she has taken the battery...


1.) Shut down the system completely, remove the battery, and disconnect the power adapter.
2.) Press and hold the power button on the laptop for a few seconds. This drains all the power lingering in your Mac.
3.) Re-insert the battery and power adapter (if you were using it before), and turn your Mac back on as your normally would.

Completely white/gray screen


First try this: shut it down, disconnect the power cord, pull out the battery, then hold the power button for a full 10 seconds. Reinstall the battery, reattach the power cord, turn it back on.
Still doing it? Put the reboot disk that your Mac came with, or the disk to the version of Mac OS X that you're running.
To start from disk hold "C" as your Mac is first turning on from a complete shutdown.
