My trackpad suddenly stopped working

My trackpad suddenly stopped working a while ago. The computer is six years old and I don't want to put a lot of money into it. Any tests or fixes out there?

Trackpad suddenly stopped working

All of a sudden, my trackpad would not work at all. I hooked up an external mouse and rebooted the ibook. It came back fine. What would have caused this on a new ibook - 3 weeks old? It has been working great with this one glitch.;

In System Preferences, there is a setting which disables the trackpad when a mouse is plugged in. What is yours set to do?

What to do if your MBP trackpad suddenly stops working

I woke up this morning and it was looking like a bad day, as my MBP built in trackpad stopped working. After resetting and trying several things, nothing worked. Then I remembered hitting this about a year ago and that the solution was to reset my PRAM (OS X Mavericks: Reset your computer’s PRAM). Following the instructions, I reset it and sure enough, my trackpad came back.
Unfortunately it is not at all obvious that this solution work. It appears to happen after system updates. This happened with Mavericks once and now has happened with Yosemite
Hey Apple, how about having some good docs that point to this as a solution?

Some trackpad functions suddenly stop working

Hello!
I have no idea what causes this, but when I'm working on my MacBook, sometimes a couple of functions of the trackpad suddenly stop working. The functions that stop working are always the same: all of the "More Gestures" found in the "Trackpad" system preferences. Just scrolling and clicking always continue to work when this problem occurs.
When I just log out and log in again or restart my MacBook it works again, however, this can get quite annoying when you have to do this all the time.
I cannot figure out what causes these functions to suddenly stop working. Does anybody know a solution for this?

Is your MacBook one with an easily removeable battery? Some users have noted that batteries, particularly older ones, sometimes expand and interfere with the trackpad. To test for this do the following -
Shut down your MacBook.
Remove the battery. Examine it for signs of expansion. If any are found DO NOT use it again.
Leaving the battery out, connect to the MacBook's AC power adapter.
Start up your MacBook. Test it to see if the trackpad works normally.
If the problem goes away with the battery gone, or if you notice expansion of the battery, replace the battery.
Best of luck.

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.

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.

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.

It seems when i do something simple as typing text, it'll stop working and give me a "Adobe Photoshop suddenly stop working". My CS4 32bit version seems to working fine with whatever i'm working on. I'm running a fresh install of Windows 7 64bit Ultimate on a new computer Intel quad core with 4gig of ram if that helps. Sorry if this have been asked before but i couldn't find anything on these forums. Thanks in advance.

i deleted the prefs file and now i can open photoshop. but it seems as if it crashes if i open ANY file with ANY text, no matter what the font is.

My usb that i have been using on my computer for a while suddenly stopped working, but is still glowing and letting me know that it is connected, but not showing up in disk utility

Either the physical drive or the enclosure electronics has failed. The light you are seeing is powered by the USB connection, the power, electricity, all USB ports put out. That doesn't mean the actual physical hard drive or the USB to SATA bus electronics are working properly. If it doesn't show in Disk Utility then it is DEAD.
Most of the time it is the enclosures electronics that fail. Removing the physical drive from the enclosure and put it in another enclosure or using a SATA to USB adapter, one that has it's own AC power supply, might allow you to get the files off the drive.

Satellite L300 suddenly stopped working - new motherboard needed

My Sat L300 suddenly stopped working the other day.
It kept freezing to start with, then nothing at all. So, I kill-disked the HDD and tried to re-install Windows (XP).
During the install it threw up a message that some internal components had been incorrectly installed and needed to be reinstalled.
I was told to remove the memory cards and re-seat them.
That did not work. I thought that perhaps the HDD was damaged, so I fitted a new one, and started to reinstall Windows.
Once again, same message. One of my colleagues at work suggested that the Motherboard was probably U/S.
So I have been trawling the .net to find a replacement. Laptop out of warranty! I am told that some other serial numbered motherboards will work with this laptop. Don't really want to get a motherboard only to find its never going to work! My unit has an SPS number of: V000138330.
I am being offered one with an SPS of: V000138390.
Any ideas? Will this one work?
And if it does, will it give me the functionality that I used to enjoy?!
Sorry for the long sob story.
Any advice gratefully accepted.

Hello Andy
Sorry but can you tell us more about your notebook? which model do you have exactly (L300-xxx)?
Do you have European model?
Has your notebook valid warranty?
Maybe I have misunderstood something but why you want to exchange mainboard if the warranty is probably still valid?

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

HT201263 My iPod touch suddenly stopped working. It was fine, but when I went back the screen had gone black and I was unable to turn it on. It is now unresponsive and my computer does not recognize it when it is plugged in. What should I do?

My iPod touch suddenly stopped working. It was fine earlier, but when I went back a few hours later, the screen had gone black and I was unable to turn it on. It is now unresponsive and my computer does not recognize it when it is plugged in. I thought it just needed to be charged but there seems to be a larger issue now. What should I do?

Let your ipod die. Then when it is dead charge it adn turn it back on. After that it should be fine.

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
