Black screen Last night the computer screen went crazy with all sort of horizontal lines with multiple colors. It then shut down. I am able to hear boot up and shut down noise but nothing shows up on the screen. I have it plugged in to adapter. Is this the battery or something else?

    Getting an ibook for 200 isn't a good idea. Those ibooks aren't worth 100 bucks. The money you spend on the logic board... you can just buy a whole NEW computer. 200 plus 700 for repairs, save up a little and get a new one.

    I have an ibook I stupidly bought for 300. NEVER AGAIN. Now it sits on a shelf in my office, unused, and dead.

    My advice, don't waste your money on ibooks. They're great until they get the logic board problem. Then it's trash. (My opinion).

Sounds like the famous video card chip error (the video chip isn't soldered well). If you have Applecare, Apple should fix this for free. If you don't, you could try to put a coin on video chip (with the ATI logo), so the coin pushes the video chip down.
Or you can try to solder it yourself again, try this link:

This is an old G3, from 2001-2003ish? Sounds like the old logic board problem. There was a recall... had mine replaced 3 times.

I am on the internet and it keeps blacking out and completely shuts down.

I am sorry - but your information is very unclear. Does your screen go black or is it a manner of speech? It sounds as if your machine is shutting down. If so, it means your problem is not with the internet but with your software, or possibly hardware.

My other computer, G4 Macbook Pro, has a screen issue. When it is turned on and in process of coming up, the screen shows large sections of odd colors such as light pink or light green or light blue. Then...

Connect an external display to the computer. If the lines and distortion shows up on the external display its the video card, which is attached to the logic board. So, the whole logic board will need to be replaced.
If the lines and distortion don't show up on the external display the issue is the LCD module, which will need to be replaced.

Mac Laptop has black screen

Try starting in safe mode, this usually bypasses the graphics drivers, which could be in a funky state:
To start up in safe mode

Shut down your computer and wait 10 seconds.
Press the power button.
Immediately after you hear the startup tone, hold down the Shift key.
You should press the Shift key as soon as possible after your hear the startup tone, but not before.
Release the Shift key when you see the gray Apple logo and progress indicator (spinning gear).
