Keyboard suddenly stops working

When my computer has been on for awhile (a day or so) the keyboard stops working if I restart the computer I usually can type again. This just started recently and I've had this computer for about 3 years. Anyone else had this problem?

Actually was checking some other threads on the site and this seems to be a common problem. Found this advice so hopefully that will fix it.

I called Apple Support today, and after doing what they told me I haven't had a problem since (knock on wood!).
Try the following:
1) Shut down your MacBook and disconnect everything (including power adapter and battery)
2) Hold the power button for 10 seconds (resets something...don't remember what)
3) Put the battery back in and plug the AC adapter back in.
4) Turn on the computer and as soon as you press the power button, press in the following keys: apple, option, R, and P, and keep pressing. As soon as you turn on the computer, you normally hear the cool little apple chime. After you hear the chime, the screen will go black and act as if it's turning on again. Once the little Apple chime plays the second time, release the four keys.
Hopefully this will correct the problem. I did it about five hours ago and haven't had any problems since.

Wireless keyboard suddenly stopped working - changed batteries still did not help

Hi
I have an Envy 20 all in one touchscreen with a wireless keyboard which has been absolutley fantastic until now. The wireless keyboard suddenly stopped working while composing an email. I replaced the batteries and checked them with a volt meter to ensure 1.5v. They are a name brand alkiline battery. I tried re-booting the computer and pressing the blue connect button under the keyboard. The only keys that seem to work are the volume up/down and mute; the rest of teh keyboard does not. Any idea? I like the factory keyboard so I am hoping it is not a faulty keyboard. After market keyboards will use a USB port.
Thanks
Thor

Hello @Thor66,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that your wireless keyboard is not working and you are looking for assistance. I am providing you with an HP Support document: Wireless Keyboard and Mouse Troubleshooting, which will walk you through the troubleshooting process for your wireless keyboard.
Now if this does not work and you have to replace the keyboard do not fear you can replace the keyboard and the dongle without using another USB port as the one that is in can be replaced. I would be happy to assist you further and/or walk you through changing out the dongle from a new wireless keyboard, but first I would encourage you to post your product number for your computer. I am linking an HP Support document below that will show you how to find your product number. As well, if you could indicate which operating system you are using. And whether your operating system is 32-bit or 64-bit as with this and the product number I can provide you with accurate information.
How Do I Find My Model Number or Product Number?
Which Windows operating system am I running?
Is the Windows Version on My Computer 32-bit or 64-bit?
Please re-post with the requested information and I would be happy to provide you with assistance. Thank you for posting on the HP Forums. Have a great day!

Two keys on external keyboard suddenly stop working, cannot log in

I have an iMac with Snow Leopard, USB keyboard (not wireless). From one moment to the next the "a" and "s" keys suddenly stopped working. I checked in the Universal Access and Speech panes as others with similar problems were advised and this was not the problem. I tried restarting the computer to see if that would help but it did not, and now I can't log in because these letters are in my password. HELP!!!!

Try another USB keyboard. (most any brand will work)
Personally I use Logitech MK120 - USB Keyboard & Mouse Combo's with all my Mac's.

Some of the keys on my keyboard suddenly stopped working. Has anyone had this happen?

Some of the keys on my MacBook suddenly stopped working. Has anyone had this happen?

yes. look over to the right under "more like this".

Keyboard suddenly stopped working

The keyboard and trackpad suddenly stopped responding on my Macbook Pro 13" (Fall 2011) when I was doing regular work. When I rebooted the computer it says it cannot find any keyboard. Any suggestions?
I'm sorry I don't have much more to add.
edit: Now it's working again, just out of the blue! Doesn't feel too good though.

Try resetting the PRAM and the SMC - often fixes odd faults like this.

Right-click on Magic Mouse and Volume Controls on Wireless keyboard suddenly stopped working

I am running Mavericks 10.9.2 on an Late 2012 iMac.
One morning the right click on my Magic Mouse and the volume controls on the wireless keyboard stopped working.
These mouse and keyboard themselves seem fine; they work okay ehn used on a MacBook.
Everything else about the mouse and keyboard is fine.
This seems to be a problem what has been around for a whole, with a wide variety of solutions.
I have read
https://discussions.apple.com/message/16799039#16799039
https://discussions.apple.com/message/23474052#23474052
https://discussions.apple.com/message/19660884#19660884
and have tried
Clicking on and off the 'right click' checkbox in the Mouse System Preferences - No effect
Deleting /Library/Preferences/com.apple.Bluetooth.plist - No effect
Restarting in Safe Mode - When starting in safe mode, the computer crashes out and restarted
Resetting NVRAM / PRAM - Is it CTRL+CMD+P+R or CMD+OPT+P+R ? Neither work for me (I do try it using a wired keyboard, but never get the double chime)
Upgraded to 10.9.2 - no effect
Moved the /System/Library/Extensions/AppleHIDMouse.kext and AppleHIDKeyboard.kext and and back in (and re-authenticate) - No joy
Moved the /System/Library/Extensions/AppleHIDMouse.kext and AppleHIDKeyboard.kext from a working MacBook on same OS - Made the keyboard misbehave even more
Has anyone got any other cures for this?
Thanks in advance.

Here is what worked for me. My scrolling on the mighty mouse and a few buttons on my wireless keyboard weren't working properly. I reset the SMC, a link explaining the process is below. Hope it helps you too!

Satellite A30 keyboard suddenly stopped working - how to remove and replace?

Hi all, n00b to laptops and first post. Ok, I usually build and repair desktops, so much easier to gain aceess!!
My daughter switched on her A30 laptop last night and only 2 keys worked. Tried rebooting and getting into BIOS but couldnt. Tried getting it to boot into safe mode, only the up and down arrow working so could not select safe mode...doh. Am guessing this must be a harware problem.
Rebooted into Xp an opened up notepad....this time about 5 keys working. Reboot, 3 key etc etc.
How do I get to the ribbon cable to make sure it is seated properly. Is it common for a keyboard to fail in this way and is it easy to get a replacement?
At the mo, have all the small screws I can find out, removed battery, DVD rom and hard drive. Seems to be held towards the middle and rear. Dont want to force it and break something else!
TIA.

OK, so I had to laugh....flip the little cover on the top of the laptop and there are the 2 screws that hold the keyboard in place....lol
The ribbon cable was just about in its connector. Pushed it in and engaged the two locking tabs on the plastic retainer...job done!
Put it back together, fired up and Bingo! we have a keyboard again!
Oh well, may help someone else I guess.
Now she has no excuse for not doing her homework!

Wired keyboard suddenly stopped working.... help!

I have just turned on my iMac to find the Bluetooth Set-up Assistant trying to "locate a keyboard" even though there is one plugged in and was working perfectly fine when I last shut down. I have tried all 3 USB ports at rear of iMac and the keyboard is still not recognised but the mouse works. I am currently using a keyboard from an older Mac that works fine so is there anything I can do to get the computer to accept the new keyboard again? Thanks in advance for any help!

Hi, try the SMC Reset route..
Then Repair Permissions...

Hello, my backspace and enter keys suddenly stopped working. I have done a PRAM reset and used the keyboard viewer to see if the buttons work and they don't. The PRAM reset didn't work either

Dear All, the backspace and enter keys on my wireless keyboard suddenly stopped working. Im using OS 10.7.5 and have tried a PRAM reset which didn't work. I also used the keyboard viewer to see if the keys worked on that but they don't. This is driving me mad, can anyone please tell me what to do? It happened just after an update but this could be a coincidence. Thank you for your time

For my computers, though some of them support BlueTooth devices and accessories,
my preference and economy of standard, is to have wired USB and also use powered
USB hubs for accessories.
I've used USB wired keyboards and mouse products; and some I've bought from the
original owners who had upgraded to BT, and never used the new Apple USB model;
so I have spares of these on-hand since they seldom fail, but do work when BT won't.
{A SMC reset should not cause a problem, or seldom has; but can solve some.}
In my opinion, the wired USB keyboard is an essential accessory, if not a necessary
primary means of user access on a continuous basis. At least until the wires fail...!

The keyboard and trackpad to my 2008 MacBook suddenly stopped working, what's wrong with it/ what should I do to fix it?

The keyboard and trackpad to my 2008 MacBook suddenly stopped working. I've restarted the computer several times and no help. I had some keyboard maintenance done a few months ago at a repair shop so I don't know if that has anything to do with it. What should I do?

First thing I would try would be to remove the battery from your MacBook, connect the computer to it's power adapter and start up, then see if the keyboard and trackpad work normally. Some older batteries have been known to expand and interfere with keyboard and trackpad. If this works, replace the battery.
Best of luck.

That panic was not caused by third-party software. If the problem is recurrent, the possibilities are:
A stale or corrupt kernel cache
A damaged OS X installation
A fault in a peripheral device, if any
Corrupt non-volatile memory (NVRAM)
An internal hardware fault (including incompatible memory)
An obscure bug in OS X
You may already have ruled out some of these.
Rule out #1 by booting in safe mode and then rebooting as usual. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
You can rule out #2 and #3 by reinstalling the OS and testing with non-essential peripherals disconnected and aftermarket expansion cards removed, if applicable. Sometimes a clean reinstallation (after erasing the startup volume) may solve a problem that isn't solved by reinstalling in place, without erasing.
Corrupt NVRAM, which rarely causes panics, can be ruled out by resetting it.
If your model has user-replaceable memory, and you've upgraded the memory modules, reinstall the original memory and see whether there's any improvement. Be careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol. Aftermarket memory must exactly match the technical specifications for your model. Memory that is either slower or faster than specified may be incompatible.
The Apple Hardware Test or Apple Diagnostics, though generally unreliable, will sometimes detect a fault. A negative test can't be depended on. Run the extended version of the test.
In the category of obscure bugs, reports suggest that FileVault may trigger kernel traps under some unknown conditions. Most, though not all, of these reports seem to involve booting from an aftermarket SSD. If those conditions apply to you, try deactivating FileVault.
Connecting more than one display is another reported trigger for OS X bugs.
If your system is not fully up to date, running Software Update might get you a bug fix.
In rare cases, a malformed network packet from a defective router or other network device can cause panics. Such packets could also be sent deliberately by a skillful attacker. This possibility is something to consider if you run a public server that might be the target of such an attack.
If none of the above applies, make a "Genius" appointment at an Apple Store to have the machine tested. You may have to leave it there for several days. There isn't much point in doing this unless you can reproduce the panic, or if you can't, it happens often enough that it's likely to be repeated at the store. Otherwise you may be told that nothing is wrong.
Print the first page of the panic report and bring it with you.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you know how to restore, and you have at least two independent backups.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair

Outlook to iPhone sync failure – Sync suddenly stopped working for calendar events but continued for contacts and notes.   Finally Fixed!!! SUPPORT TEAM – PLEASE SEE THIS – Complete explanation of cause and correction steps.

The issue: Outlook to iPhone sync failure – Sync suddenly stopped working for calendar events but continued for contacts and notes.   Finally Fixed!!!
SUPPORT TEAM – PLEASE SEE THIS – Complete explanation of cause and correction steps.
The cause: It is now clear what caused this problem. For years I had several “all-day” events in my Outlook calendar (birthdays, anniversaries, etc.). In May 2012 I decided to make some of them one hour events so I could add alerts to remind me of the event. I did this by dragging them in Outlook to the time I wanted and expanding them to the time slot desired and then adding the alarm.
The symptom: Syncing stopped working for the calendar but continued working for contacts and notes. I didn’t realize sync was failing until months later when I missed two very important phone calls, so when I noticed it the cause was not obvious.
The failed attempts: I’m head of a software firm and my calendar sync is a crucial to my business life so I took this on with a vengeance. From a quick look at events in Outlook and the iPhone I could see that the problem started in May 2012. Events before May were in both Outlook and the iPhone but events after May were only one or the other. Unfortunately I had changed several other things at the same time relating to other events so again the cause was not obvious. MANY calls with AppleCare proved them incompetent so my internal IT guys assisted trying many things. We tried a huge number of calendar changes and several versions of iTunes, iPhone OS and Office as well as both iPhone 4 and 5, all without success.
The fix: After 18 months of frustration, MANY hundreds of $ expense and MANY hours of wasted time I saw a blog that had a calendar sync problem and it indicated all day events were related. I changed the display of the Outlook calendar to the list view, added columns so I could see “all day” event check marks as well as times of events, sorted on the “all day” event column to move them to the top, and for all events that were “all day” events AND had a start and end time, I removed recurrence and then added the annual recurrence back…
After I fixed all events that had BOTH “all day” set and had a start/end time, I tried another sync. It synced for the first time in 18 months!
Problem occurred May 2012 – fixed Nov 2013

Hi, to remove dummy '_ModGrp' entries, rather than crashing the 'Suppr' key on your keyboard, you can use this basic VBA macro (launched for instance from Excel).
It will recursively remove all '_ModGrp...' folders
Sub RemoveFolders_Click()
    Dim oOutlook As Outlook.Application
    Set oOutlook = New Outlook.Application
    Set objNameSpace = oOutlook.GetNamespace("MAPI")
    Call CleanFolders(objNameSpace.Folders)
End Sub
Sub CleanFolders(objFolders As Outlook.Folders)
    For i = objFolders.Count To 1 Step -1
        If Left(objFolders(i).Name, 7) = "_ModGrp" Then
            objFolders.Remove( i )
        Else
            If Not objFolders(i).Folders Is Nothing Then
                Call CleanFolders(objFolders(i).Folders)
            End If
        End If
    Next i
End Sub

HP Pavilion dm1-4000au Entertainment Notebook PC_Keyboard and Touchpad Suddenly Stops Working

Hi there,
I have an HP Pavilion dm1-4000au Entertainment Notebook PC (QG411PA) running Windows 7 Ultimate 32-bit for more than a couple of years already. During those times up until now, whenever my laptop is on standby for an hour or so, its keyboard and touchpad suddenly stops working, regardless if its running on battery or on AC power.
I always ensure that I have an external mouse in order for me to navigate properly and pull up the on-screen keyboard in order to type once that issue arises.
All appears to be updated in terms of Windows Updates and I even reformatted it, but issue still persists.
Is this particular issue that I am experiencing a harware issue? Perhaps a software issue? Or maybe a defective model itself?
Your prompt response is highly appreciated.
Sincerely,
Led

Ethernet suddenly stopped working for no apparent reason

My late 2011 MBP is usually functioning as a desktop with external display and keyboard/trackpad, so I have it connected via ethernet when it's on the desk. However, my connection suddenly stopped working for no apparent reason.......... BUT clearly not a router problem as there's no problem with the wifi connection. System Preferences > Network > Ethernet is telling me:
Status: Connected. Ethernet has a self-assigned IP address and will not be able to connect to the internet.
Dunno how this happened, as to my knowledge I didn't actually do anything to cause this problem, just randomly stopped working. Any solutions much appreciated, thanks :-)

Please post a screenshot of the Network preference pane. Be careful not to include any private information.
