    people shouldn't try to help someone who leaves one line and thinks they are going to get help. we aren't magicians and you are asking for free help, the least - really, the least - you could do is actually describe the problem.

    could you please give more info.

    Are you sure the adapter works with other computers? Try that one to troubleshoot before you move on to think that the problem is the computer. It could also be that the battery is not charging or has a problem and the light that remains "amber" as it is charging but should change to green when is done never changes because of that problem.

Hey, if this problem still exist for you... try this.
Hold down the power button and see if the computer responds.  If you hear a loud beep sound, that's good. Release the power button... The computer should come on.
Of course if that doesn't work.  Try checking to see if the battery has any charge by pressing the button on the bottom of the batter.  Use those light sensors to determine the charge level of the batter. If there is just one light flashing, the battery is not charged.  Give it some time to see if it changes.
You can also, just remove the battery, plug in the power cord again, and then try to power on the computer. 
Let me know if any of this helps.(if its not too late)  = |
Anywho, have a great day!

My old g4 powerbook is dead, power supply seems to be alright , all battery lights come on on the back but nothing from pressing the power button, no noises , black screen....


HI Nick, I had a similar problem with my Titanium G4 Powerbook in the past. The batterry lights showed OK, and at first glance the original Apple transparent saucer shaped power adapter seemed to be working. But then I realized that the very thin conducter wires were broken where the flexible wire meets the connector plug. I cut into the plastic insulation and soldered the wires-a very tedious exercise I might add. This worked for a few weeks, and as I was at sea on a ship, it kept me going. But before long the same problem occurred-an apparent dead computer. I solved the problem by purchasing a 65 watt power adapter from PowerbookMedic. It was dirt cheap and I haven't had a single hiccup since, and that was 3 years ago. You can always see a Genius at an Apple store, if there is one close to your home. These people are amazingly helpful.

Lap top won't come on


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

I have a powerbook g4 17" 1.67ghz and it decided not to turn on ne-more... what could be the problem???


If you are not using the AC adapter (you are using only the battery), then the battery may be dead - simply replace the battery. If you are plugged into the wall, and the light on the power cord, where it meets the computer, is green, the unit is receiving power. If the unit is receiving power and it will not boot at all, then either the motherboard or the hard drive is most likely problem. You can replace the board, but it may end up being more expensive on an older G4 than it is worth. Once you are able to determine if the unit is receiving power, the only thing you can really do from there is take it to a repair shop and have them perform a test on the power supply, hard drive and/or the motherboard to see which one of those is causing the problem. If the hard drive is fine, you will most likely be able to recover your files.

Turn on my powerbook G4 but there isn't a chime and nothing comes on the lcd screen


If there's no chime, your problem could be anything from a dead battery or bad AC adapter to a dead logic board.
Does the tip of the adapter on your AC connector light up? If not, that's a problem.
When you push the button on the battery, do you get at least two glowing LCDs? If not, that's a problem.
Otherwise, try the following: remove the battery and the AC jack to make sure the machine is off. Now insert the AC jack, and reset the power management unit by pressing the following multi-key combination:
Shift Control Option Power-button
Wait five seconds, then press the power button to attempt to start the computer normally.
The instructions above are for the 1.5GHz PowerBook G4; the instructions MAY be different if that is not your model.

Apple G4 15" has been charging all night - will not power on? Ideas?


If you are plugged into the AC adapter, it should power on even with the battery removed.
Turn off the computer. Remove the AC adapter plug and remove the battery.
Reset the power manager by simultaneously pressing and then releasing Shift-Control-Option-power button. Do not press the fn (Function) key while using this combination of keystrokes.

Wait 5 seconds.



Press the power button to restart the computer. If it still will not restart, you may need to contact a local serviceperson.

Screen won't turn on


when the computer boots does the screen light up? if it does the first thing you need to try is when you turn the computer on is to option boot. That is done by holding the option key while turning the computer on. after it boots you will see the the hard drive listed on the screen it will be a icon, if there you should be able to boot up. If the computer does not boot and your hard drive is still listed you most likely have a logic board aka mother board issue.

Computer will not start up


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.
