Help! My Keyboard and mouse will not work all of a sudden on my G4

I am having a problem with both my keyboard and mouse. I have a graphite G4 and recently had to run disk warrior on i. I have had endless problems with this computer and even have a 2nd hardrive on it since it only came with a 10Gig. Needless to say it is all I have right now. I am running os x 10.2.2 on it and a few days after I recessitated it with disk warrior my keyboard and mouse suddenly went dead while I was on the internet. I tried pluging the two into different usb ports both on the tower and also into the flat panel mac display that it came with and nothing. I plugged in my wacom tablet and that works. i then tested the mouse and keyboard on my husband's dell laptop and they work. I cannot reset the PRAM b/c the keyboard won't work! What do I do??????

Besides removing the battery, you can do a PMU reset which will zap PRAM. See Mac PRAM, NVRAM, CUDA/PMU & Battery Tutorial
You only describe your Mac as a G4 graphite, which I believe is a G4 AGP. Here’s a diagram showing the location of the PMU reset button.

Look at these links to determine which model G4 you have.

Bluetooth keyboard and mouse will not connect

I loaded a linux iso on a usb. Loaded it on a reboot. It may have been corrupted or something, because it did not load correctly. I rebooted the computer again and now the bluetooth keyboard and mouse will not connect. How can I fix this?
Thank you.

My wireless keyboard and mouse do not work on my All-In-One computer?

Q.: My wireless keyboard and mouse do not work on my All-In-One computer?
A.: If your wireless keyboard and mouse do not work even after changing the batteries, please try re-syncing them by following these steps.
1. Make sure the computer is on, plug in the USB receiver. Push the button on the USB receiver until it flashes blue.
2. While the receiver is still flashing, press the red connect button on the keyboard (Make sure the batteries are installed). The USB receiver should stop flashing after pressing the button on the keyboard. It may take up to 8 seconds to sync.
3. Repeat the same process for the mouse. Push the button on the USB receiver, then press the connect button on the mouse (Make sure the mouse is on).
Note: This applies to all MSI All-In-One computers that include the ES500W wireless keyboard and SW130 mouse.

"This machine has an added 4 USB ports, could this be causing a problem?
It definitely could be the source of the problem. Perhaps the PCI card was bumped loose during shipping?
Have you tried removing the card? That's where I would start.
Keep us posted.

T410 keyboard and mouse will not wake from 'Power Source Optimized'

'Power Source Optimized' from the Lenovo Power Manager puts the computer to sleep after a prescribed time.
To rewake it appears that one must press the power key briefly.
The login screen for W7 appears and prompts me to enter my password.
Only problem is - the keyboard and mouse refused to wake up. Could anyone tell me what the trick is?
Thank you!
Ade

if you use an external keyboard and mouse, would they work when you wake up the computer?

G500s Touch keyboard and mouse pad not working

I've uninstalled and reinstalled the drivers. The solution center says everything is fine. USB mouse works, as does the touch screen, just not the actual keyboard or pad.
Please help.

For additional information - i now have my keyboard working, but the touch pad is still not working. I went to the lenovo site and downloaded the elan driver again. it extracted, but once i clicked for it to install, it says No Appropriate Driver to be installed.

Keyboard and mouse don't work at all in 1 on 2 times!

When my computer has already been started up once and I start it up again, then the PS2 keyboard and mouse will not work, but only 1 on 2 times precisely! So one time the keyboard and mouse are working, the other time keyboard and mouse are not working. The rest works fine. Quite mysterious isn't it? Who has a solution to this?
If the power has been totally off and I put it back on again, then keyboard and mouse work properly.
I have looked into the BIOS, Integrated Peripherals for something like PS/2, I couldn't find it, I have put out several things in the BIOS, but it didn't work.
Now follows a list of everything I see when I am into the BIOS with the standard settings for integrated peripherals.
Could it help to put items on and off here?
Onboard device ->
raid config
on chip usb [v1.1+v2.0]
usb/storage support.....enabled
usb mouse support......enabled
sata 1/sata 2...............enabled
sata 3/sata 4...............disabled
ac97 audio.................disabled
mac lan (nvidia).........auto
via on board 1394......enabled
On board i/o chip setup ->

onboard serial port 1.........3F8/irq 4
ir function select................disabled
onboard parallel port.........378/irq 7
parallel portmode..............ecp+epp
epp mode select.................epp 1.7
ecp mode use dma..............3
I couldn't find a possibility for a hardware reset in the BIOS. It should be in PnP/PCI. Does anybody know about these things?

Have you tried using a usb keyboard/mouse?
I don't use any usb, only use PS2. Maybe it is possible to use some sort of a PS2 to usb converter, but I would rather like the PS2 to work.

5 and j will not work on my wireless keyboard

Is there a fix for my apple wireless keyboard. My 5 and j will not work. Everything else works fine.
This wireless keyboard is the newer model without number keypad attached.

Try resetting the PRAM. If that does not help, the KB is probably broken.

Since my G5 died I was thinking about getting a Mac Mini, but I have a ViewSonic Monitor (from 2004) and a USB keyboard and mouse - I also have the external drive tha downloaded my files on to. Do you think the monitor, keyboard and mouse will work on it?

Since my G5 died I was thinking about getting a Mac Mini, but I have a ViewSonic Monitor (from 2004) and a USB keyboard and mouse - I also have the external drive that I downloaded my files on to. Do you think the monitor, keyboard and mouse will work on it? Would I have to get a hub so I could use the stuff I already have? Is that viewsonic too old to work on it?
What else would I need? Please advise...

Yes for keyboard and mouse.
The monitor will work if it has an HDMI, VGA ir DVI input. If it only has a VGA input you will need this adopter

Keyboard and mouse won't work

Help! they keyboard and mouse have stopped working on my iMac. I had adjusted the universal access features for my mother who is legally blind to try the Voice Over features on my iMac and I thought that I hadn't reset something correctly when the keyboard would not let me type an e-mail this morning. Now, not only does the keyboard not work, but the mouse is not responding. I have a Pages document open and am unable to type or click anything in it, the pages menu, or anything on the desktop. when I move the cursor over the menu options or across the desktop icons on the bottom of the screen, where I should be getting an arrow to select the items I get the bar cursor like you get when you are typing something. What did I do and how do I fix it!

By the way, the keyboard and mouse do not show up in the system preferences either. And this is a 1.83GhZ dual core, white Macbook if it makes a difference.

Wireless mouse will not work at the top of the page on ANY website while running Firefox 7.0.1

I am currently running Firefox 7.0.1 and have not had many problems until today. I have noticed that my wireless mouse will not work at the top of any website. This means I cannot log into many sites. I have also noticed that during page downloads, I have to move the mouse in order for the page to load or it just pauses. Any help would be appreciated!

If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
*Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Keyboard and trackpad are not working, Keyboard and trackpad are not working

I'm using MBP 15" late 2008 with Maverick OS. A couple of days ago, the internal keyboard and trackpad are not working at all. I did all the troubleshooting. I even reformat it; installing the snow leopard and re-installing the maverick but no good result. I believe there's no problem with my keyboard because i can still do PRAM on my lappy. Everytime i'm booting up my MBP, it always looking for bluetooth trackpad and keyboard. I have not used those bluetooth peripherals from day 1 i've started using MBP. I just read on the internet about the same problem has happened on MBP 13" retina and APPLE fixed it by updating the software. I wish Apple will also do something for the old MBP to fix the intermal keyboard and trackpad problem.

Keyboard and mouse no longer work when booting into Rhapsody

I still have a bootable partition with the last release of Rhapsody (aka Mac OS X Server) on my Power Mac G4 but it's been a while (years!) since I actually booted it up. The G4 also has bootable partitions with Mac OS X 10.2, 10.3 and 10.4 (and is in daily use running 10.4.11).
I used to boot into Rhapsody occasionally, mostly for interest's sake, occasionally to test Unix software on legacy systems; I haven't tried to do so since installing 10.4 until now.
When I booted up from the Rhapsody partition today, all went well -- the system started up fine, and the login screen appeared -- but the keyboard and mouse no longer work. I even got out the original keyboard and mouse that came with the G4, with no luck.
I assume that recent firmware updates have bypassed support for Rhapsody. I guess I'm not surprised -- it was a developer-only release, after all. But has anyone a solution?

Adding to the above: I also tried plugging in an Microsoft USB keyboard at the point when Windows freezes at the Windows log-in screen. The keyboard is not recognized and the only way I can leave this screen is to power-off the computer.
