No sound output

check the audio output settings of your components. THey may be set for dolby digital which your receiver can process but your TV can not. Try PCM stereo setting or "other".

it is not an easy job to change a HD on an old iBook G4.
you need some experience in handling microelectronics.

try connecting a speaker to the sub output terminals at low volume and see if it has loaded output, if it works , your subwoofers voice coil is open/blown

To help with getting your battery to charge, try resetting the PMU

-PMU RESET-
The Power Manager (PMU) is an integrated circuit (computer chip) that is usually on the logic board of your Mac computer.

It is responsible for power management of the computer. It controls backlighting, hard disk spin down, sleep and wake, some charging aspects, trackpad control, and some input/output as it relates to the computer sleeping.

• If the computer is on, turn it off.
• Now refer to this article from Apple.com Support
Resetting the PMU for Powerbook and iBooks

If this process does not help to allow your battery to charge normally, you more than likely have a battery which may be either dead or eventually will die in its charge capability.

What I would recommend if that is the case, would be to consider purchasing a new battery from Apple or via a third party reseller like online Apple authorized resellers like Amazon.com, MacMall.com or Fry's Electronics for example. You may also Google with keywords "purchase iBook battery " and shop for the best priced iBook battery.

Again, you would only consider the latter, if the former procedure listed above does not help.

I hope this helps.

I ran into this with my home network and my old g3 ibook needed the older speed wifi to connect. I found my old wifi router, hooked an ethernet cable to the newer router (in a regular ethernet port) and connected the other end to the internet port on the old one... they linked and worked fine to provide wifi for the old G3's ..

That screen will most likely be compatible - I work on these for a living. The G3 laptop screens are usually not compatible with the G4 laptops, but all G4 laptop screens are compatible with eachother (provided they are the same size, of course.

Hi, Sorry you are having trouble,
Sounds to me like you're going to have to re-open that puppy and check all the connections, sometimes, when putting it back together, some cables are stretched and come un plugged...
Be careful, go slow...

Try this:

Go to Control Panel >> Sounds and Audio Devices. Click on Advanced button under Speaker Settings and for Speaker Setup select 5.1 surround sound speakers from the options. Click Apply >> Ok and then check.

Does the protection relay click 3 to 5 seconds after initial power on??? If not, your unit is staying in "protect" mode to save your speakers because the output transistors or output IC is shorted and sending 40 to 60 volts at your speakers. Not a good thing, but at least it saves your speakers.
Good Luck!

If the motherboard supports IRQ assignment of PCI devices then YES.
