can a keyboard that comes with a g4 go bad just to clarify i am talking about a keyboard with two usb on the key board and we think they are bad because any mouse other than wireless that we plug into it locks up the computer was on here a couple weeks ago talking to some one about freezes and we could not narrow it down and this is the only thing we could find

ANy hardware can go bad at anytime, even from absolutely brand new.

There are many causes for this from Static, to Power Surges to small very short power outages, in fact these can be the worst of all.

When the Power goes off and comes back on almost immediately this is a perfect setup to fry anything to everything in a computer or even a cooker forthat matter.

How far have you got with testing this particular keyboard?

The reason I ask is it possible it is the USB system that has a problem and it could be software or hardware.

The first thing I would try and do, is to remove the keyboard and just plug in a mouse to see if that crashes the Mac, if it does then there is a possibility of some thing wrong with the USB system.

I really need to know exactly what you have done so far to troubleshoot this problem otherwise I will end up either covering stuff you have already done and so on.

Also with any of the pre OS X systems, due to the way the OS was made, basically a whole load of patches added on to the original system and as a new piece of technology was created a patch was added to the system to get it to work. Eventually this was getting a bit out of hand and finally after many years we have OS X.

The problem itself could easily be what is known as an extension conflict, these werre very common in pre OS X systems.

In your control panels there should be a control panel called Extensions manager that lets you choose what extensions to load.

If you cannot even get at the control panels, you can hold down the space bar during restart and this will bring up the extensions manager before full OS launch, this will let you choose a basic set to get going.

This link is t oan Apple document that should help you troubleshoot an extensions conflict.
http://docs.info.apple.com/article.html?artnum=30929

I would take a look at this before dumping the keyboard.

I have used computers for a long time and I have never had a keyboard cause a situation like this. I have had them give me the wrong key, or not even respond at all but not this. So I am inclined to look a little deeper into your problem if that is what you want.

I have not tested the key board yet but i have tested just about anything else with the mac i was on here a couple of weeks ago trying to find out why the mac was freezing tried clean install of os tried new system battery tried testing cpu temp suggested new hard drive but i just put in 80 gig a couple months ago and was eventually left with only system board error ? just out of the blue happened to have wireless mouse with me & plugged it into usb on keyboard a Viola it worked but the second we plug back in the mouse we had a Microsoft optical inteli point it would run for 10 min or run for 3 hours but would eventually freeze with wireless mouse no problems no freezes ? don't get it wondering if it is just a fluke and the wireless just happened to be plugged in when the mac decided to run that day ?

What happens if you just plug a mouse directly into a USB slot on your Mac, does that make it crash.?

Also when you startup the Mac and do nothing with the mouse but do things with the TAB key and left right arrows does the Mac crash.

I really need to know if it is the Keyboard, the Mouse or the USB system itself.

Did you try and reset the PMU button on the Motherboard and have you also tried to reset the PRAM.

You may have done all this stuff I know but I need to know exactly what is going on here, especially as you have been inside the machine and installed an item in there. OK

now we are back to square one it is locking up every 5 min or so and no matter what mouse we use or if it is just plugged into usb by itself ?

This comes across more and more likea USB problem, although it is possible that the USB hub inside the keyboard is faulty.
I was not too clear as to if your computer ran succesfully or not when you just had the mouse in it, I am assuming it did for a while the nwent wrong.

When you have the Keyboard plugged in and a mouse connected, have you ever tried to start the system without any extensions on?

To do that you have to hold down the shift key immediately after a restart and the machine will tell you it is starting with no extensions on. This is a sort of safe mode as the computer itself will run, but if you do have afaulty extension, you will know immediately because if everything runs without extensions then the chances are it is an extension conflict.

I have never heard of one that affected the kkeyboard this way, but it does not mean it is impossible.

Have you ever had the chance to use a different keyboard?.

Are therre any circumstances when the computer will run OK and not crash at all ?.

One thing I would like you to do, is to remove the keyboard and mouse, and startup the computer, leave it on for quite a while and see if it crashes by itself. Make sure the ebergy saver control panel is set so it never shuts down the screen or the Power at a..

Also if you have a screen saver let it run for while and tell me what happens.
Then just plug in the Mouse and click it one time, and leave it again if nothing happens.

IF it is still running after that lot, plug the keyboard into a different USB connection if you have one and let me know what happens.

Do this both ways with extensions off and on.

There is for sure a possibility that the Keyboard is faulty, so it might not be a bad idea to borrow one to see if it works OK. IF it does then replace the old one. If it does not we are looking at either na extensions conflict or a faulty USB system, the Faulty USB could also be caused by an extension or even a control panel.

This is one of those situations where if I was at your machine I could probably find the problem quickly, but I am afraid we are limited to Email here so it takes considerably longer although we are working on that too.

my bad scanner not hooked up to SCSI CD burner is scanner is usb

When you start without extensions on, a lot of third part stuff becomes disabled, as well as some apple stuff.

I am not surprised the Quark did not open, as it has quite a lot of stuff that it installs to make sure that only the registered user can use the program.

Most scanners will not work and so on.

It is interesting that your keyboard would not let you bypass the extensions. Did you go to the Extension manager control panel to disable them?.

It seems like the computer itself has not problems it is in the peripherals or p[ossibly you have an extension that is corrupted or incompatible with something else.

I think it would be a good idea to first of all disconnect any peripherals that did not come with the system or that are not actually built in to the system, such as the USB?/SCSI? scanner and HD.

Try rebooting with the Keyboard again with the shift key held down and see if that affects anything. IF not, at the least start up with no extensions, and then go to the extensions manager control panel.

Here you can make up sets of differrent extensions. First of all start up with a basic set of Apple Extensions and see how that works. IF that is OK, you will find that there is still some stuff that will not work so you will next need to go to the next highest level of Apple extensions and try that out.

IF that works, then you are going to have to create your own set of extensions, do not turn them all on at once. use the main Apple set if it work OK in other words if the computer worked fine with no peripherals attached and only the Apple extensions enabled.
Duplicate the main Set of Apple extensions and start adding in a few new extensions in, restarting the machine making sure to save the new extensions list you are creating. Keep doing that until you reach a point where the machine does not function properly. If you manage to get it to work with all the required extension on, then the next thing to do, is to connect your peripherals one at a time to see if any of these are causing your problem.

Remember for example, that the scanner probably needs an extension so make it worki, and although you created an extension set with the scanner extension turned on, it probably did not activate until the scanner was present for it to work on.

So if the system does get crazy after you plugged the scanner in, then it is still possible that it may be the scanners Extension that is causing he problem so turn it off to check it. You may have to go to the Scanner makers web site to download a newer extension for the scanner.

All this is probably true for the CD Burner as well.

Now all this troubleshooting is dependant on noticing what happens with things like all peripherals disconnected. IF the system works fine like that, it is more than likely the extension for that device that is faulty, so you would need to turn it off and restart so you can see what happens.

I ma sorry that you are going ot have to do a lot of restarting, it is pretty much a standard joke amongst Techs that most of your time is spent waiting for the computer to restart.

One thing I will definitley mention here and that is screen savers. IN th eentire time that i was using Macs before i had OS X, I never found a screen saver free or otherwise that did not eventually cause me a problem, so keep that in mind. you might want to get that out of your system for a while .

Also if you really cannot get the system to boot up without extensions, with just the Keyboard and mouse connected, then I wouold suspect that the keyboard is definitely faulty. At least nowadays there are plenty of really good keyboards out there and they are not that expensive.


One question and that is what do you mean by your "Bad Scanner".

Sorry about the time it took me to reply back took a while to do that the keyboard did start the mac without extensions just was not holding it long enough tried adding extensions one by one and no luck it did not freeze up and has not froze up at all today not sure i understand it appears that the freezes are just random wish i had an explanation but it doesn't look like i do and when i said my "bad scanner" i was typing what i was thinking meaning that the scanner is not bad but my mistake it is not hooked up that way sorry i tend to do that sometimes the only other ? is could it be the power supply could that cause it to freeze ?

IF your system is managing to run most of the time, yet hangs up occasionally, especially if you are running any pre OS X system, then I would not be too concerned. A lot of the time the older systems would work just fine, then you would do something that just happened to be in the right sequence and cause a crash, and that was it, you locked up and had to do a restart.

Did you ever get the computer to run with a normal mouse and that keyboard?.

What Apple has done with the OS X series is make it so that in most cases if an application causes a crash, you do not have to restart the entire computer, just the application that crashed.

The problem with the Older Systems is that they allowed your software to directly access the hardware in your machine. This is one of the reasons that people still say that OS 9 appears faster than any of the Os X systems.
The reason for this is that in the OSX systems, your software is not allowed to directly control the hardware, the OS controls it for you through what is called a hardware abstraction layer. This is what allows you to just restart a crashed program and not the entire computer.

What does all this technobabble mean to you, well what it means is, that with all the extensions required to run things like scanners, advanced software like Quark Express, there is sometimes a conflict of interest between the applications, or the system, or an extension and because they are directly controlling your hardware, when one goes down, usually the lot goes down, and of course there is no record kept of it because at the moment something crashed, the entire computer went down.
This is most likely what is happening to you.

It is possible for a Power supply to be causing a crash, but usually you get warnings like a flickering screen, whenever you access the Hard Drive or CD, Etc.
If you try to use a USB device that needs more power than the USB bus can supply, you usually get a massage warning you to connect the Power supply of the offending equipment, or to get another Hub that can supply some more USB powerfor your USB devices.

In theory the USB bus can be overloaded with devices that rely on the power supplied by the USB bus, Mice, Keyboard Etc fall into this category.

Usually the message would be presented on the monitor that your are overloading the USB bus.

IF you had a keyboard that due to some electronic failure was taking too much power, and then you plugged in standard mouse, there is a possibility that you could crash out your machine. The reason this does not happen with the Wireless mouse is that it has its own separate power supply.

This is very unlikely to occur but it is a remote possibility.

If the Power Supply is faulty then I would expect you to be having continuous crashes with no way to figure out the cause except to replace the power supply.

You can test the power supply for voltages pretty easily, usually there is a +12 a -12volt supply, a +5 and -5Volt supply and a depending on the computer a couple of other supplies in the 12-24 volt range.
The problem with this kind of testing is that it does not let you know how the Power Supply is working under a load, in other words if you are still getting your full 12 volts when it is actually working something.
This is a measure of current (Amps), and if you do have a weak power supply it is the current usually that is going to be down, usually when it is under a load.
The Voltage test if it is wrong then you know for sure the Power Supply is going or gone. The test for current under a load is the for sure test of a bad power supply.
However if you measure say 10 volts on the 12 volt line then there is a good chance the power supply is going down, reading over the 12 volts say 14v is not an indicator of failure because as soon as the load is applied, the voltage will more than likely go to 12V.

I hope this lot explains to some degree how the Power supply software and the computer work together, especially in the OS9 and earlier systems, and gives you some clues as to what conditions it would take for a the power supply to cause a crash.

HI programs like conflict catcher are OK, they will disable a whole bunch of stuff as you have seen.

What you need to do now is to slowly reenable the extensions one at a time to see if you can find the one that is causing you to freeze up.

It may be that it is a combination of 2 or even more extensions that do this, but I am afraid the only way is the step by step approach.

A lot of the applications you use will need extensions to work, and if you find that you have a bad application extension you will need to check with the software company to see if they have a fix for it.

Another thing that can get you around a bad extension, is to make groups of extensions that you turn on when you need a certain application and not another. Say QUark, but not your scanner. This way you create sets of extensions that allow you to work, but have to restart and choose a different set, if yu want to use your scanner but not Quark Etc.

Sometimes it is not the fact that an extension is bad, it is sometimes the case that an extension tries to use the same memory area as another one and this is a conflict. The cure here is to figure out which extensions you need for which jobs, and hopefully find one that is the source of all you problems. This will more than likely not be the case as in these circumstances, it is often multiple extensions working against each other.
Conflict catcher is way better than the apple extension manager as it controls all the extensions.
The trouble here is tha tit also controls extensions that are needed for Basic system operations as well. SO try and make a complete set of Apple extensions as these are the minimum requirement for your machine.
Work up from that base as long as it works to start with, and add in the extra extensions until you hit the one that is zapping you.

OK
