Starting problems, computer freezes, keyboard and mouse stop working

Hi can anyone help? My powerbook has just stopped working, rarely starts, when it does keyboard and mouse stop working after a while or even before i am able to login. At one point I was getting a grey screen with the words, memory access invalid???? Please help...
powerbook G4

power surge could have damaged something inside, or it maybe unrelated to the problem.
PowerBook can get hot if there is some short circuit inside and power flow is disrupted, also it's possible that the fans are not working properly.
as a guess, it is likely either hard drive or logic board problem.

HELP: Keyboard and Mouse stop working

I plugged a 4GB flashdrive into keyboard; received low power notification; plugged it into computer instead; it loaded on desktop, HOWEVER, keyboard and mouse no longer work - shut down computer for 5 minutes, still not working, unplugged and replugged in connections; removed flashdrive, shut computer off for 30 minutes; still does not work. The only positive thing, I have a laptop so I can ask this question. All the files I need are on the other computer, however. HELP

Hello! If the usb ports tripped out you'll have to reset the pmu. With all the external cables (usb/firewwire/monitor/a/c etc) unhooked press the pmu button once then reconnect and restart. Below are a couple of example of the pmu location. Tom

Keyboard and mouse not working correctly after installing Windows 8.1

I was forced to upgrade my computer to Windows 8.1. My keyboard worked fine until the sytem did a reboot. Numbers on keypad stopped typing and letters were being capitalized when the caps lock was off and the numbers across the top will only type the symbol above the numbers.
I looked up this problem and it seems I need to enter UEFI settings and disable Intel XHCI mode. When I get into the UEFI settings I cannot make any selection from the startup menu. Both my keyboard and mouse stop working.
Any suggestions?

Thank you for posting a response. Fortunately, I didn't have to try your solution because the computer resolved itself.

My Keyboard and Mouse Quit Working and Computer Slow to Boot Up

Last week my iMac wireless keyboard and mouse quit working. (Batteries are OK). That same morning the computer started taking a very long time - several minutes - to boot up. I've been using a wired keyboard and mouse but I'd rather get back to the wireless ones. The other discussions I've read all refer to Bluetooth but I don't find that on my computer. Help!!   Thanks.

Hello cindycat,
Love the name ... so evocative
Go to Apple menu > Systems preferences > Internet & Wireless.   There you will find bluetooth.   Click on it and In the bottom right corner is a purple ?.   Click on that to learn about setting up bluetooth.
Incidentally, batteries are often not okay (though you may think otherwise).   The only batteries that are okay are top quality unused batteries.   And even then you should check the contact points inside the mouse in case there is corrosion.
Keep us advised.

Mid 2011 Macbook Air - Yosemite keyboard and trackpad stopped working, the only button that worked was the power button, only one USB port works.

I have a Mid 2011 Macbook Air.
Upgraded to Yosemite last week.
Three days ago I was using my Macbook Air for the first time since upgrading to Yosemite. I had been using my Macbook Air for approximately 30 minutes, I was using safari and the keyboard and trackpad stopped working (would not respond). The only button that worked was the power button.
I rebooted and they were still not working. I plugged in a USB mouse and external USB keyboard, only one USB port would work (the Left USB port if looking at the screen) so I had to swap between keyboard and mouse.
After logging in there is a bluetooth icon at the top of the screen with a sawtooth line through it. Bluetooth is unavailable and the bluetooth icon is missing from the system preferences menu.
If I run a hardware test by holding D (on USB keyboard) at startup it says that no problems are found and at the conclusion of the test the keyboard and trackpad start working again. When I log on the bluetooth is working again.
I shut down the Macbook Air and when I started it again the keyboard and trackpad and right side USB ports were all not working again. I logged in using the USB keyboard and mouse and the bluetooth not available sawtooth icon had returned.
I ran the hardware test again and at the conclusion of the test the trackpad and keyboard started working again.
I have tried deleting com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile from /Library/Preferences/ and tried resetting SMC and Power Functions but this did not fix the issue. The only thing that seems to work is running a hardware test - obviously I don't want to do this every time I use the computer.
I do not believe any hardware is faulty/damaged - I think it has something to do with bluetooth/Yosemite.
I do not have the Macbook with me at the moment, if you have suggestions that I can try or additional checks/info you require please let me know and I can get back to you.
Thanks,
John

Hi!
I have exactly the same problem, and I can't find any solution.
I can't even track down the root of the problem: the Bluetooth/Wifi module? The trackpad? The keyboard/top case? The logicboard?
I've tried all the usual: SMC/PRAM reset, clean install, kext cache clearing.
Any suggestion is greatly appreciated!

Windows 8.1 Onboard Keyboard and Touchpad Stopped Working.

After upgrading to Win 8.1 my keyboard and touchpad stopped working suddenly. They both worked fine for the entire Windows 8.0 release. When I upgraded to 8.1, they both worked for about 3 months. Then what started happening is the computer
would freeze during the startup process.
Now they both don't don't work. But a USB powered mouse works. So with a USB powered mouse and the on screen keyboard I have been troubleshooting. I have removed the drivers from the device manager, reinstalled the drivers, searched for
driver updates etc. Nothing works.
Can someone please point me in the right direction. PC is kind of useless at the moment.

what wilco said.
start hal using "sudo /etc/rc.d/hal start" before starting xorg. if mouse/keyboard work, add hal to the DAEMONS array in /etc/rc.conf.
imo disabling hotplugging is cheap, just ignoring a problem instead of solving it
If he don't need hotplugging, then there is no reason to use it...

Yosemite update to Mac pro keyboard and mouse not working anymore

Updated to Yosemite on my Mac pro, worked perfect for about 2 weeks then my keyboard and mouse stopped responding, both keyboard and mouse were replaced and still won't work. The computer turns on but won't respond to the USB mouse &Keyboard. Help

I have seen 2 out of the 6 mac pro's in my office do this. I am about to go to the apple store to show them.
When the computer is doing this I have tried using every wired apple keyboard in my office and none of them work. If I try the same keyboards on a windows computer or my macbook they work fine. If I use any non apple usb keyboard they work fine. My problem is if I turn the computer off for a few hours the usb apple keyboard works again so when the computer has been off all night and I pack it up to take it to applecare it is working by the time I get into the store.
I think there is a small flaw in usb port on the mac pro or the apple keyboard that when heated up from use stops the pins from contacting completely. It might be a manufacturing defect and it might be an unintended problem caused by how apple slightly modifies their USB ports.

Keyboard and mouse wont work unless booted in safe mode.

So my keyboard and mouse wont work at all when i start up normally, so i coudnt even log on, then i tried safe mode and i was able to use the mouse and keyboard and log in, then when i loged in i got some messages:
*+System extention cannot be used+*
+The system extention "/system/library/extentions/IOUSBFamily.Kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the products vendor for an update.+
And 2 others: MicrosoftMouse.kext and msdosfs.kext
Im pretty sure how i got this problem, i was using bootcamp and i got this program called MacDrive (bad Idea)and it corrupted my HD or something so i had to use disk warrior to fix it. I also used disk utility in safe mode but there were no errors it said.
and this is probably a hardware problem but i cant use DVD's anymore, my drive will only read CD's now, must be broken....
so ya, i dunno what to do exept get my drive fixed and to a backup and reinstall OS...

Hi
There are no many options which could solve this problem.
It can be a hardware problem or software related issue.
Can you use the internal keyboard within the BIOS?
Check this.
If this would not be possible, I assume the hardware is faulty.
Additionally I recommend testing the keyboard and touchpad using the factory settings.
Recover the notebook and check if the keyboard would functions. Otherwise you will need an helps from an notebook technician in order to replace the keyboard and touchpad

Ultraslim wireless keyboard and mouse not working

Hi , I purchased the Lenovo Ultraslim Wireless Keyboard & Mouse (pn: 57Y4700) about 4 months ago for use with my T60 laptop (which i use with a docking station and large lenovo monitor at work).
Everything was woking fine until last Monday when I can into work after the weekend and neither the mouse or keyboard worked. I replaced the batteries in both, rebooted the machine several time, switch the USB ports for the nano receiver, but nothing seems to have worked.
I looked online for troubleshooting options, but did not find anything.
The mouse and keyboard don't seem to have a "sych" button - if I recall correctly everything worked right out of the box.
My theory is that the nano reciever was damaged (not sure how) -- but don't know how to proceed:
can the nano reciever be replaced;
any other options to troubleshoot;
any chance that this could be a software problem
Thanks

Keyboard and mouse not working

both keyboard and mouse not working. I have changed batteries and checked drivers please help.. thank you

Thanks for the information, that is exactly what I needed.
If you are having the enter issue when using the wired KB from your old computer that sounds software related with the blog site.
What web browser do you use when on that website?
Connect your wireless equipment back and if you continue to have the issue with the letters repeating then you should inquire about a replacement for what is referred to as "sticky keys". With it being a new unit this shouldn't be an issue.
Let me know if you have other questions.

How about telling us how your keyboard & mouse are not working? Are both using batteries or are they wired? If batteries, have you checked and/or changed them? Keyboard & mouse Apple's or 3rd party? If you are still under warranty and/or have AC, call them & let Apple deal w/your problems.
If possible, try another keyboard & mouse?
Please detail ALL you have done so far in the way of troubleshooting? Need this info to avoid the been there done that scenarios.
================
When posting in Apple Communties/Forums/Message Boards.......It would help us to know which iMac model you have, which OS & version you're using, how much RAM, etc. You can have this info displayed on the bottom of every post by completing your system profile and filling in the information asked for.

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
