I was using my iMac Al 20', everything was working fine, and after I
did what I had to do, I shut it off, to go to bed, then I remember that
I had to pay a bill, and turn it back on, but when it start up I
noticed that my mouse wasn't working, I've tried my keyboard and
noticed it didn't work also ( don't know about the remote, forgot to
try it ).
I pick up my mouse and noticed that it was 'turned off' ( no light
below it ), so I've unplugged and plugged it back again, the mouse
turned on, but it still didn't move ( the cursor were at the apple on
the top ).
I've tried to change the mouse from the keyboard usb to the computer
usb, same result, tried to change the keyboard usb, unplugged an old iPod
that I use as a backup drive ( through firewire connection ) unplug the
cable that I use to sync my iPhone, nothing worked.

Re: Keyboard and Mouse don't work anymore
Hi, Sorry you are having problems,
Well Marcelo, the first thing to do in a situation like this is to restart your Mac or even better, shut down and restart. So, if you have done this, and still the keyboard and mouse don't respond, and, as you have mentioned, you have tried the other USB ports on the back of the Mac, it sounds like somehow, unexpectedly, your iMac motherboard got a shock of some kind and it killed the USB controller....
Last thing to try is to unplug the iMac completely of everything and let it sit for 10 minutes and then plug just the keyboard and mouse back in and try to see if that does the trick..
Otherwise, Apple will cover this if it is still under warranty.

Hi, I believe you have to clean your mouse. that's no joke. You have to unscrew it and and clean out al the parts with a toothbrush and tooth-pic.. If that does'nt work. replace mouse with optic mouse.
Thank you for contacting Fixya Support, I am glad to assist.
There are a few steps you can try to troubleshoot this issue:
Try a PMU Reset: * Turn of your iMac if it is already turned off * Disconnect all connections to the iMac except the power cord * Now disconnect the power cord for approximately 20 seconds * Reconnect just the power cable the keyboard, mouse and power cord, and then power your iMac G5 up.
* Check to see if the iMac boots up normally without power interruption.
* If the iMac G5 shuts off again, try these steps, another recommendation would be to remove all connections including the power cord, and lay the iMac G5 on soft cloth face down and with a philips screwdriver, remove the plate on the bottom of the iMac G5 where your RAM memory is located. Before removing the RAM however, touch your hand on the metal boot to discharge any static current you carry for approximately 5 seconds.
Now remove each RAM card and then reseat (re-install) each card.
Restore the RAM card cover with your Philips screwdriver, reconnect your power cable, keyboard and mouse and turn on your iMac G5.
See if this second procedure helps if the first procedure does not work.
Did you seperately setup the mouse? Even if you have, go into the Bluetooth preferences under System Preferences. Select the mouse & delete it. Setup a "New Bluetooth Device" and select "Mouse." Be sure to press the Reset button for 2-3 seconds to get the mouse into "Discoverable" mode. Your Mac will then setup the mouse automatically.
If this does not work, the Bluetooth chip in the mouse may be defective.
Turn the mouse over and find the small
rest/connect button on the bottom of the mouse and press it to
Reset/Connect the mouse to the receiver and work properly.
If not, try pressing the receiver button and then press
the mouse. This should be done whenever you change batteries or
Hope this helps you. Bud
Solution for the mouse. I have 8 KVM's. Most of my computers work with the KVMs. On 1 inland KVM the logitect and Microsoft optical mice do not work on one computer (but work with the other computers). They both are USB. I hook them up with a USB to PS2 adapter. If I use a ps2 ball mouse connected to the KVM the mouse works. All the Mice work if I directly connect them. Since I do not want a ball mouse I got a Frisby optical PS2 mouse. It works with all the computers on the KVM's.
I do not have a solution for the Keyboard yet. 1 computer (ASUS MB) on my trendnet or belkin 4 postion KVM does not recognize the keyboard.
i would reset your keyboard and mouse settings to default then shut down pc.. unplug components and wait for 3o secs and then try again.. if the problem persists, you may just have some loose connections especially if your pc is older..make sure there is enough slack for your mouse and keyboard wire to move around.. i know sometimes we can ruin them if we have then stretched to far out.. hope this helps.. d
