Ibook G3 will not start

IBook G3, Mac OSX was running for years with no problems.
Shut down the ibook at night but before the shut down was complete the cover/screen was closed accidently. Next morning the shutdown application continued. Now The ibook is dead, no response at all. No external reset button.
Tried several net suggestions to reset PMU

Removed the battery and charger. 
~Press all of them down at the same time.  
~Do not press the fn (Function) key by accident.
~Wait 5 seconds.
~Press the Power button to restart the iBook computer.

Plus others. Nothing, still dead.

Any other suggestions?

    Pressing the power/start button does not cause any response, no noise, no lights, no nothing. The cptr has to start in order to read the CD. Have any other suggestions? 
    Thanks for your quick response. 
    Maybe I will have to open it up and see if any internal PMU buttons.

    Recently acquired ibook G3/800mhz that was reported by the previous owner to have a bad logic board. I charged the dead battery to 4 lights and reset power management with keyboard and gave the mac a few shots at starting. At first, it only chimed with dark screen. Three more cycles of battery out-in with single resets, gave a grey screen after chime...but no apple. On the fourth cycle, it booted all the way to full operation. But, just prior to that, a white light flashed briefly by the front latch and low tone was heard. I played a bit and shut her down. I did notice the area next to the pad, above the HD was warm, almost hot.  But, to be honest, I'm a powermac G4 owner. This is my first laptop. So, not knowing if the heat was normal or not, I shut it down. After cooling briefly, there has been a concerted effort on my part to repeat and augment all that was done before but, my ibook is dead in the water. Not even a chime. Anyone out there who could give me an assist. I've read most articles regarding the video chip issue of losing proper contact and the fixes. BTW---I did tear her down and R&R the HD and took out the extra ram----nada

How do you reset power management on the ibook g3

For most situations, a restart is sufficient. If the computer has stopped responding, try these steps, in order, until the computer responds:
  1. Force Quit (Option-Command-Escape)
  2. Restart (Control-Command-Power)
  3. Force Shut Down (press the power button for 10 seconds)
Only perform a PMU reset on the computer if none of the above steps resolved the situation.

I have an ibook g3 , it works ok with mac os x but when i shut down , it did not want to open again on osx, it apears the ? question and not start again, and if i shut down the dark screan apears, please...

We ran a typical Ibook G3 14 inch battery of tests, including games, applications, and a couple other areas. Time constraints limited the amount of testing we could get done before the NDA lift (and it's already a few hours late), but we will be providing a follow-up article with further testing and information. That said, if there are any specific areas that you'd like to see tested, feel free to e-mail me or leave a comment.

When i open the google site i can not read all words in my ibook g3. i can see only question marks. how to solve the problem? please help me.

The problem most likely is that you have quite an old browser, so we just need to get you a better one that can run on your operating system.
If you are on OSX, then you should try Opera from here
If you are on OS9, then you need the awesome iCab which you can download from here

Just repaired g3 ibook. Hard drive needs formatting, as it has xp loaded on it. Ibook starts up, boot tone, proceeds to load, then screen has a file in the center of screen with the osx finder square face...

With the OS X Installer CD in the drive, try booting your mac and holding down the option key immediately after you hear the start up chime. This will (hopefully) load a firmware boot loader that will show available start up discs. Hopefully the OSX installer will show up as CD Icon. Select the Icon with your mouse or keyboard and press enter to start up with the Installer CD. From the installer you should be able to erase and format the drive as Mac OS Extended before installing OS X.

If the computer still won't boot from the CD double check that it is a retail OS X installer CD. If your CD has "software restore" or "ibook restore" or any other varient of restore written on the label; or if it names a particular model such as "ibook install" or "imac install" it is not a retail copy and may not be a bootable disc. A retail copy will only name the version of the operating system followed by the word install written on it's label and usually have a brief instruction on booting from the CD by holding the C key at startup.

Hope this helps, let me know what happens.

Install new program

I take it that you just want to run 10.3 and no longer require OS9.
After starting from the OSX install disc, run Disc Utilities. Form there you can erase the hard drive. You should then be able to install OSX.

Can you connect an external monitor to the Macbook? You can verify your lcd screen this way.
You may need one of these connectors:
