USB on ibook G4

I bought my ibook G4 in May, and I am not sure if it has usb 1 or USB 2.0. Does anyone know when they started putting 2.0 on the ibook or how I can find out what I have? (it doesn't mention what version I have in my system profile).
thanks!

Hi Jim,
Welcome to Apple Discussions
I believe Apple began putting USB 2.0 in their iBooks in April 2004. I am almost positive both of yours are, but I could be wrong. Here is Apple's Press Release regarding the iBook G4 April '04
I hope that helps,
Jon

Welcome to Apple Discussions!
You can buy a 3.5" drive enclosure with USB that
supports IDE, remove the hard drive from the Firewire
one and put it in the USB enclosure. Mind you, the
iBook G3's USB is the old slow USB 1.1, and will only
transfer at up to 12 Mbps and can't boot off that
drive.
As for fixing the blue screen issue, once you have
your data backed up for certain, then you can go
ahead and check and see if the following will work on
the broken machines:

http://docs.info.apple.com/article.html?artnum=106464

And if none of those works, let us know more about
the broken machines one at a time, and we can see
what we can do to fix them.

Ibook dual usb video issue

hi, i have a dual usb 600mhz ibook g3, the video is screwy you can still make out items on screen, this happens only when booted into the operating system, during bootup the apple logo and grey screen are fine and during target disk mode the firewire logo moves around all perfectly fine, so cant be a hardware issue? ive played with the system prefs and nothing, anyone got any ideas, thanks in advance

You could try booting into Safe Mode. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
You will see your normal desktop. Once completely started up in Safe Mode, restart normally, and go to Applications > Utilities > Disk Utility.
Select the named boot volume in the left sidebar ("Macintosh HD" unless you've renamed it). Repair permissions on it.
See if a little hard drive maintenance helps things out.
If that doesn't help, can you set up a new user and log out and log back in as the new user in order to see whether it may be a preference problem with your user account?
Do you have the Mac OS X 10.4 Install disc and is it readable by the iBook?

Restoring dual usb iBook (summer 2001), can't connect to internet

Hello, I am trying to restore my ibook using the restore discs. It is a dual usb g3 ibook, and the restore cds will be putting 9.0 and 10.0.3. Ideally, I'd like 9.2.2 and 10.4.8. Anyway, I successfully restore the software, and everything works until I try to connect to the internet. I use comcast highspeed, and am connecting to a wireless network. The TCP/IP is set for 'airport wireless' and the setup assistants work without a problem. However, when it tries to access a webpage, I get the following error message: "The attempt to load (website) failed." Any advice or suggestions? The airport connects and I have full strength signal. Thanks for any suggestions!
G3 iBook, dual usb (2001) Mac OS 9.0.x

Hey Tom, thanks for the suggestion. The modem is in a roommate's room, but he's already alseep. I will give it a go in the morning. My iMac has no trouble connecting, and between 3 roommates there's a g4ibook, a dell, a psp, and a homemade desktop that all connect without any problems. Here's hoping a reset will do the trick. Fingers crossed

Getting started with an iBook G3?

Hey,
I just got an iBook G3 (500mhz, snow, airport, 10gb hd, upgraded ram), to compliment my iMac (G5 rev c) and I'm a little new.
It was used, I got it via trade.
Does anyone have some tips for me to get started with it ? I'm wanting to upgrade the HD to at least 20 GB, and to max out the ram. Any hints on that ?
Also, where can I get a new battery and charger ?
Also, what else should I know about it ?
It will mainly be used for writing (novel, fan-fics), surfing the web (wirelessly), and when I'm traveling...
Oh, it has OSX10.2 installed.

Hi, Josh. Welcome to Apple Discussions.
How much RAM is installed?
Does it have the original AirPort card installed? (You may want to install one, if not, to enable wireless access to the internet.)
Did the original system CD's and the OS X 10.2 software CD's come with it? If not, try to get the person you got it from to give them to you. You will need them if you intend to upgrade the hard drive (and for maintenance, even if you don't upgrade the hard drive).

Enough dual USB G3 iBooks suffered from a logic board problem that Apple began the iBook Logic Board Repair Extension Program in January of 2004. Check out the FAQ page and be aware of how this logic board problem manifests itself.
It has been suggested that you can minimize the chance of a logic board failure of this sort by never picking it up by the front left corner alone. Pick it up with both hands or in the center under the trackpad.
It's also a good idea not to close it any more often than you need to in order to minimize the chance of the backlight cable (and other cables and wires) becoming pinched in the hinge or broken. When you have some time, check out the Discussion thread in the Displays Forum entitled 90 degrees and black out!!!!
Information on using the battery to maximize both life and lifespan can be found here.
You can download the manual for the iBook (Dual USB) from this page:

Good luck, and happy iBooking!

Dead hard drive or ibook?

I have a 2 year old 12" iBook G4. For a while it has had problems that I have just dealt with. For example, if you rest your wrists next to the mousepad in the wrong way it can cause the pointer to jump across the screen, and sometimes makes it crash.
But now it seems completely dead. I recently travelled with the machine, and I am afraid it got banged too hard. When I hit the power button the screen stays black, but the hard drive spins VERY loudly. The only way I can get it to go off again is by flipping it over and removing the battery. When I flip it over the hard drive sound gets worse. I can't even put one of the apple disks in and try booting from that, because there is already a DVD in the drive that I can't get out.
What can I do??? If my hard drive is dead, is there a way to salvage my data? Will using it as a firewire drive with another mac work? Help??!!

Hi Ronda,
Thanks very much for your reply. I explained my problem and everything I did to try to fix it to Applecare US on Sunday, and they authorized an extention to my warranty to make the repair. I am counting my lucky stars about now. Yeah Apple! Hopefully this fix will last awhile, but in the meantime I will back up regularly and starting saving my pennies for a new iBook!
Cheers,
Brenda
Hi, and welcome to Apple Discussions.
This is not the fault in the logic board that was
covered by the iBook
Logic Board Repair Extension Program. However, it
does sound like the memory that is soldered to the
logic board has failed. This means you will need a
new logic board.
Here in the United States, I know of places that will
repair it for $195 plus shipping, but I don't know of
any inexpensive repair places in the UK.
Your "serial number of death" isn't, really. The
program was gradually expanded to include all the
Dual USB G3 iBooks, so every serial number is
included in the program.
If it turns out to be an expensive repair, maybe the
money would be better spent on a new iBook?

Problem with iBook powering on... Need help diagnosing please

Hello,
So for awhile my iBook G3 (dual USB, 700 mhz, 12" display) when the power is pressed the computer chimes and the hard drive will start spinning and then nothing happens. After a few seconds I can hear the drive stop spinning and the only sign of power is that the keyboard will light at the caps lock key.
I tried doing a PMU/PRAM reset and the iBook did a long beep noise, then the hardrive started spinning, then power light started flickering, and than it chimed and that's it.
Not sure what to do with it. I love this computer, and all though it's older and well out of date, it's ultra compact and worked great for wireless internet surfing when away from home. I'd appreciate any help to help figure out what this problem is and if it's worth paying to get it fixed or to replace it.
Thanks for reading,

First, check out the Apple Knowledge Base article on troubleshooting portables that won't turn on or start up to see if something there helps.
It sounds like you may be having logic board problems. Enough Dual USB G3 iBooks suffered from the logic board problem that Apple began the iBook Logic Board Repair Extension Program in January of 2004. Check out the FAQ page and if the symptoms look familiar and it is not past the three-year time limit, give Apple a call.
You can find the original purchase date of the iBook, by entering its serial number into the box at the bottom of Apple's main support page under "About Your Support Coverage."
If it is past the three-year time limit (and it probably is), you may want to consider trying the shim fix suggested by John Sawyer in the Apple Discussions iBook G3 (Dual USB) Displays Forum:
[Y]ou can often fix this yourself by removing the iBook's bottom housing, and placing a shim of any sort, about 1mm to 1.5mm thick, onto the raised square on the bottom shield. I use a Scotch mounting square--you can get them in hardware stores and many grocery stores. When you reinstall the bottom case, it will press against this shim, which will press against the graphics chip, and may allow the chip to come into better contact with the logic board.

If the shim fix doesn't work (or you're leery of trying it), DT & T Computer Services in Fremont, California offers the cheapest repair I've found. They have a six-month warranty on the repair.
Once you get it fixed, try never to pick it up by the left front corner alone. The theory is that picking it up by the left front corner alone can contribute to logic board failure when the case flexes, causing the graphics chip to come loose from the logic board. If you're picking it up in your left hand (as I often do mine), pick it up in the center under the trackpad.
If you can't manage to get it fixed free or on your own with the shim fix, I almost think it's a better idea to put the money you would spend on a repair toward a new MacBook. They are such a spectacular upgrade over the iBook G3. Hard drive specs, USB 2.0, RAM, processor, Tiger, the newest version of iLife, built-in AirPort Extreme, Bluetooth capabilities, and built-in iSight camera. If you can afford it, that may be the way to go. With a new MacBook, you have the option of using Migration Assistant to transfer your data to the new computer, but that likely won't work if you can't get the iBook to start up at all. However, with a new Mac, you may be able to retrieve some of your data using FireWire Target Disk Mode.
Good luck. Let us know how things go.

IBook G3 & iWork

I am starting college on Monday and I have a gliding instructor job coming up in the summer. As a result, I have been looking at getting an iBook to make my time more productive and portable. I want it to run Panther and need it to run Microsoft Office 2004 and iWork. With regards to iWork, I only need it to display the presenations through a projector, I can use my eMac for the creating part.
What kind of an iBook should I be looking for on eBay? Minimum iWork system spec requirements are 500MHz G3 and 128mb RAM, is this a fairy tale or realistic minimum system reqs?

Hi, and welcome to Apple Discussions.
A 500 MHz iBook usually has a 10 GB (actually 9.3 GB), which can really cramp your style.
Also, I would recommend maxing out the RAM with a 512 MB chip which would bring it up to 640 MB (or 576 MB if you happened to get one of the earliest ones with only 64 MB on the logic board).
Actually, if you can see your way to waiting for a week, MacWorld Expo is in San Francisco next week. If new models are announced, you may be able to pick up a new G4 iBook at a nice discount. They are only $999 right now, and if you buy from MacMall they offer a free memory upgrade (you pay an installation fee) and free printer and bag (after rebates). This may decline substantially if new models are announced at MacWorld on Tuesday.
A 500 MHz iBook is nearly a 5-year-old model. It was manufactured two years before Panther was released and three years before MS Office 2004. If you can find one that has at least a 20 GB hard drive, it may work all right for you if you upgrade the RAM, but it won't be nearly as nice as a newer model.
There's another thing to consider. Do you want wireless connectivity? If so, and you still want to go with a G3 iBook, you probably need to hunt for one with the AirPort card already installed because the newer (faster and cheaper) AirPort Extreme card won't work in the G3 iBooks (but does work in all G4 iBooks). Apple no longer sells the original AirPort card that works in a G3 iBook, and they are getting scarce (and expensive).
You may also want to consider the fact that iBook G3 (Dual USB) computers have had some problems with the logic board. Enough dual USB G3 iBooks suffered from this problem that Apple began the iBook Logic Board Repair Extension Program in January of 2004. The program covers G3 (Dual USB) iBooks that are less than three years old. If you are buying one that is older than that, you need to be a bit wary because someone may be trying to get rid of one with a bad logic board.
The average lifespan of a lithium-ion battery is two to three years, so you need to think about the cost of a replacement battery if you are going to want to use it on battery power (or buy one whose battery has been replaced recently).
I hope you find what you're looking for. We have three used iBooks, ourselves, and really enjoy them a lot. But I paid over $1000 for my first 500 MHz iBook (used--on eBay--640 MB of RAM, AirPort card installed, Combo drive) in the fall of 2002, so that $999 for a new one (AirPort Extreme is included in the new ones) is looking very good to me. And you would get Tiger with it, too.

What Logic Board fits an iBook G3 900 mhz?

Several keys in a row fail repeatedly on keyboard on G3 iBook

OK, here's the situation: A couple months ago the "9", "O", "L", and period key on my G3 dual USB 12" iBook stopped working. A little search in here and across the Internet found the suggestion to try reseating the keyboard cable. I did so. The keys started working again.
Then it happened again... and again. Each time, opening up the computer, removing the airport card, removing the metal shield, and disconnecting the keyboard cable and then connecting it again fixed the problem for a short while.
I got sick of this, and figured it was a keyboard error, as USB keyboards don't seem to be affected by this problem. I ordered a new iBook keyboard, installed it, and it worked... For a couple hours. Then the SAME keys stopped working again. Clearly, it wasn't my old keyboard.
Does anybody have any suggestions or ideas on this problem? I don't see any problems with the connector itself. The cable is solidly seated when connected. All seems perfectly normal to the naked eye.
I'm reduced to carrying around a small USB keyboard, which makes my iBook a little less elegant and useful. I'd love to be able to fix this problem.
Thanks.

So here's a weird one: This has happened- with the same keys, even- on a different 12" iBook; One that worked perfectly for months before shipping to a new owner. I'm hoping it's the same easily-fixed issue- the metal plate over the optical drive being bowed from some quirk in shipping- but not being able to help out personally (in another state) makes it hard for me to troubleshoot this for the new owner. I feel bad that this happened after it worked for us, and I want to make the new owner happy with the iBook.
Apart from the other suggestions, is there anything a complete Apple newbie (the new owner) could do? I suspect they will be afraid to crack it open to do the necessary fix, but I'm at a loss. I hate to direct them to a Genius Bar and have them pay to have something simple done to fix this (not a good first impression of Apple!) but I don't want to see anyone inherit a problem, even though it didn't exist when I shipped it (the new owner even says the keys were working when they got it, but that they quit working a short time later!)
I guess my real question is: What would a tech charge someone to deal with a similar "keys not working" issue? Any chance of some charity on the Apple Store's part when it comes to showing someone how to open an iBook, and check for crumbs/bowed metal/what-have-you?
Of course, this issue could be completely different from mine. I have no way of knowing what's happening. But the same keys?!?! Is this a known issue?
I just feel bad that a malfunction cropped up after I sold it, even if it was an as-is, private sale, and I'd like to make sure this person doesn't walk away with a bad first impression of Apple quality, let alone my sincerity in offering a good, working computer!
Incidentally, the other iBook- the one described in this thread originally- was sold to another guy earlier this month (once I knew the issue was fixed; I wanted to move up to a MacBook) and the new owner has reported no problems. I doubt he'd let me off the hook if the issue came back.
(And yes, I'm positive the two iBooks didn't get mixed up, either! The one that never had this issue had a cosmetic blemish that made it easier to distinguish from the other one, which did.)

Can I use my iBook in Europe with no converter?

I know with my iPod, all I need is a plug adaptor as the power charger does both USA and Europe so no need to carry a converter.. are these older Dual USB G3 iBooks the same in that respect? All I need is the plug adaptor but no converter as the power charger unit does it for me?

Yes, the iBook is the same.
The Apple iBook's power adapter is designed to be used worldwide. All you need is the outlet plug adapter.

Ibook Screen Death with a twist?

My Ibook screen is doing the typical fickering and eventually goes out after 1 minute, but when I had it hooked up to my big Mac via firewire it seems as if the whole system dosen't respond (it will mount when I can see the screen but when the screen goes out so does everything else) . I know that the screen is one thing but why would it affect the computer thru firewire (can't drag out data/ can't unmount disk etc)? What are the parts do I need and do I have to have good soldering skills (mine suck)? P.S. I can drag a couple of things out to my G4 before the screen and system becomes unresponsive.

You may be able to get the iBook to remain responsive in FireWire Target Disk Mode so you can retrieve your data by this method:
If the iBook is on, shut it down and wait 30 seconds (or longer). Pick it up in your left palm to the left of the trackpad and squeeze the case there between your palm and left thumb as you push the power button and key combination to start up in FireWire Target Disk Mode. Do not let up the pressure on the case. Continue applying this pressure as you save your data to the other Mac. If you let up and the iBook dies or freezes, you will have to start over, allowing it to rest several hours or overnight before beginning again.
Let us know how things go.

IBook will not sleep

Since upgrading to Tiger, now when I close my iBook lid, the computer will not sleep. The only way I can get it to sleep is to unplug all peripheral devices (including my power cord) and select sleep. It used to sleep automatically on closing. I've tried adjusting my energy saver choices in System Prefs, unclicking receive faxes in System Prefs, and all other funky suggestions I found online but to no avail-it will still not sleep when I close the lid. Does anyone have more suggestions? I travel a lot and like to store my computer in sleep mode in my computer case, but now it runs instead and wears my battery down!

Hello,
Unfortunately, I think your problem is hardware related. From your logic board, running through the right hinge of your display, there is a cable that is connected to your display inverter board, and a device in the display, called a reed switch. This cable contains several wires (6). The reed switch is a device that, when nearby a magnet sets the computer to sleep. The magnet is positioned underneath the keyboard so that when the lid is closed, the computer is set to sleep. If a wire is broken (most likely in the hinge), you may have one of several problems. For example, your sleep function will not work. Or, as in my case, the backlight does not work, so the display goes dark. Only time will tell which cable will break first, so in your case it was the one to the reed switch.
What you need is a 076-1073 PCEBA Reed Switch with Cable for
dual USB white iBook. It is an original Apple part and can be purchased from http://www.smalldog.com for $20. However, replacing the cable is somewhat tricky, but not impossible. I did it without previous laptop surgery.
There is also another discussion thread on the backlight issue. It has some good links.
This is what I think is the problem.
Good luck

IBook motherboard problems???

I just bought my first Mac an iBook G3. I started cheap to see if i would like it and i do. But someone told me that the iBook G3 is notorious for having motherboard problems.Is this true for all iBook or was it just a select few? and how will i know if i have an iBook that was affected by this?
Thanks

Enough Dual USB G3 iBooks suffered from the logic board problem that Apple began the iBook Logic Board Repair Extension Program in January of 2004. The program is mostly over now, since there was a three-year time limit from the initial date of purchase. They were discontinued in October of 2003, so it's highly unlikely that any remain eligible for repair under that program.
The program began with just a limited number of serial numbers of 800 MHz iBooks. It was gradually expanded to include all iBook G3 (Dual USB) computers.
There may be no way of knowing whether or not your iBook was one that was repaired. I have read (and believe) that you can decrease the chance of logic board failure by never picking it up by the left front corner alone. If you are picking it up with your left hand, grab it in the middle under the trackpad. Another idea is to put it on a hard lap desk or acrylic cutting board, and always pick the two up together. (The case has a tendency to flex — on some iBooks more than others — and the theory is that the flexing of the case can allow the solder on the graphics chip to loosen.)
That said, there are many, many happy iBook users out there who never knew about the iBook Logic Board Repair Extension Program because they have had no problem whatsoever with their iBooks.
Good luck with yours.
