External Mouse and Keyboard Stop Working When X220 is Docked and Screen is Closed

I have an X220 with a docking station, external monitor and external keyboard/mouse. When I start the laptop from a cold boot and it's docked, my external mouse and keyboard work fine with the screen open or closed.
If I undock and redock with the screen closed, the external keyboard doesn't work and the mouse cursor moves, but the mouse buttons don't do anything. If I open the screen, then the keyboard and mouse work fine.
I've swapped the keyboard and mouse and still have the same problem, so it's not the kb/mouse. This is a brand new X220 and the issue has been occurring since it was purchased.
Any thoughts?

hey mhambalek,
hard to say what's going on, though i would recommend heading to http://support.lenovo.com , do a full update of your unit.
also, if the external keyboard & mouse & monitotor is connected to your unit without the docking station, does the same thing happen?

Helix keyboard stops working when dock battery reaches 3%

My other post has more details but the title says it all. My Helix keyboard stops working when dock battery reaches 3% even though the tablet battery has a charge. This seems to happen every time. A hard reset of the dock gets the keyboard working again. Any ideas on how to fix this?

This is my daughter's college computer so I have not used it. I just get the panic call when it locks up.
Is there any way to get a warning when the battery is low? I assume that it has a light on the base but I can see how she could miss it when focused on what she is doing. I am not sure it comes on since the tablet battery still has capacity. I find it odd that this happens when the tablet battery still has a decent amount of charge. Effectively it eliminates a fair amount of the battery capacity available for the computer.
I have other electronics that force you to shut done at low battery levels. I am surprise that a high end laptop performs this way.

Bluetooth keyboard stops working when i plug in my iphone 5

Hi All...
Heres a question from the twilight zone where strange things happen.
My Hardware/Software used:
- iMac OSX 10.9.2
- Mac wireless Keyboard
- Logitech mouse performance MX
- iTunes 11.1.5 (5)
- iPhone 5 v7.1 (11D167)
I plug in my iPhone via USB cable, and iTunes pops up.. it detects the iphone but not 100% as it just hangs... then out of nowhere, the keyboard stops working as it looses its connection, the only way to restore the connection is to reset the iMac.
Any ideas?

Why does my keyboard stop working when I get a new Facebook message?

Whenever I get a new message on Facebook chat, my keyboard stops working on all Firefox tabs. If I switch tabs or close and open the chat it starts working again. It's definitely not a problem with the keyboard, I've had no problems typing in Notepad while messages come in on the chat.

iTunes is not fully functional when operating in Safe Mode, so its possible that the component that supports Audible content is not running. If iTunes will only run in Safe Mode then there's an issue with your installation - see Turingtest2's tutorial Troubleshooting issues with iTunes for Windows updates, in particular the section on removing all components of iTunes before installing the latest version.
I have Audible .aa files on a 2nd gen iPod Nano so there shouldn't be an issue with age ...

Bluetooth keyboard not working when prompted for wifi splash screen io7

I just upgraded to IO7 on my ipad and I use the apple bluetooth keyboard. However, when the WiFi splash screen appear to login using say Cisco's login the keyboard does not work. Meaning it does not accept keystrokes. Because the keyboard is paired there is no way to show the normal onscreen keyboard unless you unpair.
My work around has been to dismiss the splash screen and open up safari then try to hit a website which then produces the splash screen within the browser. Then I'm able to use the keyboard again. Anyone had the same issue and is there a work around as this is highly annoying.

Thank for showing interest in my situation and trying to answer, however yes...
FROM ABOVE: "Attempting to repair the keyboard accomplished nothing, however I did learn that when prompted to enter the bluetooth 4 digit code for pairing the keyboard was able to send the 4 numerical digits and striking the return key did succesfully pair the keyboard to the iPad again."
I'm going to try "Forgetting the Device", turning off the Bluetooth Keyboard, Turning off the iPad 2 iOS7, Turning the iPad 2 iOS7 back on, Turning the Bluetooth Keyboard back on, then setting it up via the Bluetooth menu again. Doubt turning off the iPad will accomplish much, but it will be good to have it scratched off the list.

Phone stops working when making/receiving calls. Screen turns off.

Hi all..
I just recieved my Pre3 Yesterday and everything seems to be working fine except that when I recieve or make calls, the screen turns itself off and stops responding, although the call continues to be made as normal.
This means the only way I can hang up, or do anything, is to remove the battery and restart the phone!
Does anybody have any ideas as to what I may be able to do?
Im located in the UK by the way.
Thank-you!
Post relates to: HP Pre 3 (Unlocked EU)

Hi,
I had the same problem after my phone went for swim in a pool for a bit.
I found on the web that I could do 3 things to see if it fixed it or not.
1. Upgrade the Software Version. Mine is now at v31.002. I did the update using the Nokia Update Application running on my PC.
Result: Did not fix the problem. Cost: Free
2. Replace the Battery. I noticed that my battery didn't hold it's change very well even after 24 hours on the charger.
Result: Did not fix the problem: Cost: $55NZD
3. Replace the ear piece. Bought a Nokia replace part on ebay UK.
Result: IT FIXED THE PROBLEM. Cost: $2.99UKD
It was pretty easy to replace the ear piece, you just need a T4 philips screw driver and something (I used a plastic scraper used for cleaning my oven tray) that will slide in between the slider gap (I saw a quick demo on YouTube) to pop open the front cover when to take the 4 screws out. Just be careful with the plastic piece around the Navi button as it can easily pop-out and tricky to get back into place.
So I hope this helps you.
Cheers
PS. This is actually a friends phone and I was seeing if I could fix it or not. He's now got a iPhone now so it's a spare one. )

External mouse and keyboard no longer work after 10.8.5 upgrade

Today I upgraded from OSX 10.8.4 to 10.8.5 on my macbook pro 17". This upgrade caused by external mouse and keyboard to completely stop working. I tried installing the 10.8.5 "combo" install (http://support.apple.com/kb/DL1676) and also tried resetting the PRAM, but neither action had any effect.
I also tried restoring to an older time machine backup with 10.8.4, but could only figure out how to restore files, not the entire system.
I've lost a day of work at this point, I need help... How can I get back to 10.8.4 or get the mouse/keyboard working again on 10.8.5??

Try booting into the Safe Mode. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application uninstaller. For each disable/delete, you will need to restart if you don't do them all at once.

Mighty Mouse and wireless keyboard stop working

Just got my iMac yesterday and everything worked out of the box. But once yesterday and once so far today, the wireless mighty mouse and keyboard stopped working.
Today I noticed after the mouse stopped moving the cursor, the little green light on the bottom of the mouse was blinking. I turned off the mouse and turned it back on, but the green light still blinked and the mouse still didn't work.
The only thing that did something was the power button on the iMac. I had to turn off the iMac and turn it back on. Then the keyboard and mouse worked again.
What's going on? Do I need to get the iMac repaired?

Hello and Welcome to Apple Discussions ...
Try deleting this file. com.apple.bluetooth.plist
/Users/YourName/Library/Preferences. Drag that file from the Preferences folder to the Trash, empty the Trash and reboot.
If that doesn't help, make sure the batteries are charged. Go to System Preferences/Keyboard&Mouse. Click the Bluetooth tab. Your battery levels are displayed there. When it gets down to one green bar on the left, install new batteries.
If none of the above helps, turn the mouse and keyboard off. Delete the mouse and keyboard from the System Preferences/Bluetooth devices window. Select the mouse in the window on the left, then click the minus - button. Now open the slider on the mouse so the green light blinks. Click + which will launch the Bluetooth Setup Assistant. Just follow the instructions. Same for the keyboard. If you still have issues with the wireless hardware, I'd take it back. You have 14 days in case you need to replace the iMac.

Mouse and keyboard stop working with Mavericks

This has happened twice now since installing Mavericks.
I'll be working along, and then all of a sudden, I am not able to click with my mouse and my keyboard stops working. I AM able to move the cursor around on the screen. But, I am not able to click on anything and I can't use the keyboard to force quit the finder. The only way to get unstuck is to press the power button on the front of the Mac to shut it down and then restart.
I am using a wired Apple Keyboard and a wireless Apple Magic Mouse. My Mac is a MacPro 2 x 2.3 GHz Quad-Core Intel Xeon Mac.
Like I said. this has never happened before. But it's happened twice since installing Mavericks.

Everytime I restart my computer, especially for updating maverick, my keyboard and attached mouse (both apple for an Imac) stop working. When I plug in an other keyboard, I can get into my Imac again. Would this SMC apply to this problem as well?
What should I do?
thanks, hb

Apple wireless mouse and keyboard stop working ... now says OS X version and bluetooth incompatible

For no apparent reason my apple wireless mouse and keyboard stopped working. I was not upgrading or installing anything, the batteries are good, nothing was changed as far as I know. Now bluetooth discovers the paired devices, connects for about 30 seconds, the disconnects ... or stays connected but doesn't work.
What's happenned ... I'm rushing to finish a big job ... any ideas? I've tried re-pairing but doesn't work ... says that OSX version may be incompatible with device bluetooth ... I'm using Lion so maybe there is another lion problem?

Hello:
Barry: What do you mean with "making devices favorites"?
This is the method:
Go to system preferences>bluetooth. Highlight an item in the sidebar. If detailed information does not appear, click on the little gear and select show more info. Then click on the gear again and select favorite.
And how could an hardware-related problem be (temporarily) solved rebooting the OS?
Intermittent problems are, IMHO, most often caused by hardware. Restarting will occasionally "fix" problems - why, I do not know.

Macbook Air Mid 13 TrackPad and Keyboard Stopped working.

Both trackpad and mouse work when I have to sign into my account; however, once I'm on my windows screen both stop working. It tries and searches for bluetooth keyboard and mouse. I don't know how else to fix this issue. Please help I have tried all recovery options and erased everything on disk utility ( i saved my files first ) . for now i have been using an external mouse and keyboard. I also had the newest software update os x yosemite but when i re installed os x it installed lion but still the same problem.

finally its fixed!! ...i went on the mac osx hints site...someone suggested resetting the pram and pmu...i was worried i wouldn't be able to hit the key combinations because of the whole keyboard thing...but apparently, my keyboard still worked until it got into os x...so i reset the pmu with shift-option-control-power while the computer was off...and voila...problem solved!!
thanks for all your help....you *******!! lol jk

Snow Leopard hangs after LDAP login, mouse works, keyboard stops working

Afternoon,
It was suggested that I post my question below in a server forum rather than a client form.
Mike
Morning,
Earlier I posted a question about 10.5 brightness and 10.6. The user will deal with the brightness issue, so that's moot at the moment. I still have an issue with 10.6 hanging.
I have configured 10.6 to authenticate using OpenLDAP from a Red Hat box. The authentication works fine. I have added /home from the same linux box to the list of NFS mounts (Disk Utility->File->NFS Mounts?, I'm not in front of the mac box at this moment to verify). The /home filesystem does get mounted.
Very quickly after logging into a non-local, LDAP account, the mac box becomes useless in that I cannot start any programs, I can't logout, I can't do anything. If I double click on Terminal (Applications->Utilities->Terminal) I get the brief flash like Terminal is starting, but the application never appears on the desktop.
I can still ssh into the mac box. When I ssh in and run top, to see what's consuming the CPU, the machine is idle. My guess right now is every application is timing out or failing to start. I see nothing hogging the CPU nor the network.
When I log in using a local, non-LDAP account the mac box acts as I expect it to when launching applications, looking at NFS, surfing the web, etc.
Any ideas what's going on, what to check for, and how to fix this?
This is an iMac 27". I may need to contact Apple support on this one.
Mike
Additionally, the mouse continues to work, the keyboard stops working (wifi both), and the finder starts reporting -10810 on every application open attempt. I can select the Apple->Logout or Restart options, but nothing happens. I must ssh into the iMac and 'shutdown -r now' to get back to a login so I can login as root to make further changes.
Mike

I was able to grab a crash log if that helps.

Early 2009 MacBook Air. On startup no keyboard or mouse me to login. Neither is the USB working so I cannot use an external mouse or keyboard either.

Early 2009 MacBook Air. On startup no keyboard or mouse me to login. Neither is the USB working so I cannot use an external mouse or keyboard either. If I keep restarting the machine suddenly sometime I get mouse and keyboard control and I am able to login and work. After sometime though mouse and keyboard Control is lost again and the machine hangs.
Lately another problem has cropped up. Now the machine starts up and seems to work for longer time but I have no 0 key and USB everything else is fine.
What could be the issue

1. Reset PRAM. http://support.apple.com/kb/PH4405
2. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
