You could be in a screensaver mode or your graphics card might be blown. Try accessing system preferences and turning off the screensaver and/or powers aving options. Your G4 could be in sleep mode. Try starting from Disc Warrior and clean up your opertating system. May help.

SOURCE: My apple G4 12" don't start, i hear a noise like

Try booting from the install disc. by holding down the "C" on the keyboard. If it boots normally from the disc you have a hard drive problem and it will need to be replaced.
If it doesn't boot normally from the disc you have a logic board problem and it will be needing to be replaced.

If I shut down system it will not start again for a few days. Then I have to push switch on tower and monitor at the same time


It sounds as though you may have a power supply going bad. The photo that accompanies your question is a G4 MDD. Is that the exact computer you have? If so, the power supplies are known to go bad on these specific machines. I had to replace my power supply last year. I would suggest - if your Mac is a MDD - doing a search on that topic. I found very good help at the Apple forums. If you determine the power supply is the culprit there is a gentleman in Austin, Texas who rebuilds power supplies. He sells through ebay and offers a very good and fair deal. His ebay ID is baltimora2000. That's who I got mine from and it is still running well after over a year of use. Hope this helps you out.

Can a vizio monitor be used with an apple G4 desktop computer


Oh wow guess I was proved wrong! But I read here that alot of people were having problems, my only concern is if the computer has a pc mode that can use hdmi or mini display port. If not you may have to mess with the settings to get a good picture.

Hi, I have a PowerBook G4 17" laptop and the monitor has gone dim, to where it appears black. I can barely see images on the screen, but the backlight is not working. Could this be a video inverter...


Yes, this does sound like it's an inverter issue.
The only way to get this part is straight from Apple or from a Authorized Service Provider who get there parts straight from Apple.

Roomba has been scratching my hardwood floors.


My brand new Rhoomba worked perfect the first time. The second time using it, I was aghast to come home to the same issue.

My marble floors now have long scratches across the wide expanses of floor. In the areas where the rhoomba (I witnessed it doing this motion the first time I let it clean) does those small geometric patterns like in confined areas, those same geometric patterns appeared scratched into my marble floors in my condo!!!!

What's worse? They do not intend to do anything to repair the damage....just refund my money.


R---I---P O----F----F! DO NOT BUY ONE!!!!!!!

Kids tiped tower over. no start.


You've probably thought of this, but make sure the fall did not disconnect the cable that connects the tower to the monitor.

Network a G4 (OS 9) to a eMac (OS X)


OK - first, crossover cables let you network PCs together without a switch or router. I would strongly recommend returning the crossover cable and buying a router so that you can use both computers on the internet at the same time.

Second, the eMac monitor can not directly be used as a monitor for your G4 - it's not built that way. However, you can use Screen Sharing on OS X (if both have Leopard) or Apple Remote Desktop software (if you buy it) to remote control the G4 using the eMac.

You will DEFINITELY need a monitor on the G4 in order to set it up at all, so I hope you have that.

Keep in mind that you can buy, for less than $200, an LCD screen that is larger and better quality than the eMac, and it would leave the eMac useful as a second computer. Since the eMac is unlikely to work at all with Leopard, and you'd have to buy Apple Remote Desktop, you're going to spend less money by buying a separate screen for the G4.
