What sound card are you using? It has to be external for you to switch it. When a computer is dropped, the hard drive and logicboard are under severe danger. The drive is constantly spinning anywhere between 4200 and 10k rpms. If the logicboard endures any shock there could be endless possibilities to failures in addition to them being intermitten. Can you specify which G4 you have, in processor speed and machine/display size? And I take it when you mean " no sound", you also mean no Apple start-up chime when you boot the machine?

2006 powerbook G4. my screen will get glitchy and i can see multi color squares and lines randomly on the screen. when i move a window the pixels chase and outline my movements. any ideas?

sounds like the video card is dying. I was able to hold off on one dying by downloading a fan controller that kept the machine cooler, but with the age of the G4, it's likely damaged. Consider replacing or the fan controller.

Computer randomely shutting down

As a 25 years experienced technician, some times I have clients who come to me saying " I have a computer that keeps shutting down randomely " they had it checked by some tech. and he can't find a clue what's going on, even after changing the power supply...

The reason is that the tech did not noticed the swollen capacitors on the main board usually around the CPU or the RAM...

Conclusion! if your computer is randomely shutting down, befor changing any hardware, open the box and check for the physical state of the capacitors (round aluminium cans covered in a plastic shrink) the top are suppose to be FLAT not about to burst.

They can be changed by a proffessional tech. with good tools and lots of patiance (not to damage the feed trough's on the board)

Powerbook g4

If you have the operating systems disk, you can boot from the disc, and once the setup come dump, choose password reset from the "utilities" drop down menu. Change your password, shutdown, and reboot.

My powerbook g4 no longer recognize my builted in airport, have no airport now. The only way to make my g4 work in hook an either net cable to my g4 into my router. Makes my laptop very stationary, what...

What I would suggest is reseating the airport card as it may be the card has come loose or the cable is not connected properly. The following support page on the apple website will tell you how to do it.

Failing that you will probably have to buy an new airport card or a wireless usb adaptor. You should be able to pick one up from ebay fairly cheaply.

Hope this helps.

My older G4 white 12"macbook laptop drops the wireless connection

try to update the Mac Os x and also the airport card drive.This can solve the issue

I have a Escort 2000 Peavey P A System. The fan is making a noise when I switch it on, but as soon as it ''heats up'', the noise stops. Is it because of the cold weather or is the fan giving notice?

It might be giving notice, it might have some loose screws, but then again, it might just need some oiling.

There's probably a sticker on the rear side of the fan (where the power wires come out), remove it, underneath you'll see an aluminium cover near the center. Take this cover off with a pointed knife or similar, it should come off with just a slight force and you should now see the axis fixed in place by a clamp.

You just need to put a drop or so of oil, just make sure it reaches underneath the clamp into the bearing/bushing and if the bearing/bushing was just a bit dry or dirty and if it's not really damaged then the fan shoud now run quietly.

Put the aluminium cover and the sticker back in place, try it out, if it's silent, you win, if it's still giving notice then it should most probably be replaced.

Thanks for the help!

Hi there,

That sounds like it would fix it. Have you recently updated the memory in the imac? It may be incompatable. Otherwise it may simply have become faulty over time.

Please make sure that before you open up your imac, you're not voiding your warrenty. I know that the aluminium imacs allow this, but i dont think the G4 versions do.

Hope this helps,
