Hciconfig crashes when turning off bluetooth

Hi there.
I'm having an issue with hciconfig / bluetooth on my Lenovo X220. Whenever I turn off bluetooth (using laptop-mode, gnome3 bluetooth menu or hciconfig) while my bluetooth mouse is connected, i'll end up getting the following messages:
http://pastebin.com/ggj5fWqC
Bluetooth becomes unusable after that, laptop-mode-tools does not switch modes anymore, can't unload / reload thinkpad_acpi, sometimes the system freezes completely.
This error occurres on two independent archlinux installations on my laptop, one of those is a minimal rescue system.
Any suggestions on how to approach / fix this issue?

Hi Barry,
I have reset SMC and PRAM, but the problem remains. With my mouse synchronised, if I turn bluetooth off the systems crashes right away...

Bluetooth/system pref crash when turning off bluetooth

Hi all,
I have a Apple Wireless Keyboard and a Kensington Bluetooth Mouse that I use with my Macbook. They work great. However, sometimes when I click "Turn Bluetooth Off" in the Menu Bar, It disconnects the items but stays with the Black symbol like Bluetooth is On, but when I click on it Turn on and off are both grayed out. After this I try to open System Preferences and that won't respond so I ultimately reboot. What am I doing wrong? This doesn't happen every time I turn bluetooth off.

I suspect it is an incompatible configuration from my previous Macbook G4 17" as well.
Any ideas on which specific files I should try to change? I have been digging around but can't seem to find the relevant files yet.
Thanks.

HT1414 I set up my newly received IPhone 4, connected to my wi-fi, then turned it off. I now want to turn it on and turn off bluetooth, but when I go to settings, general, none of the options respond. I touch them and nothing happens.

I tried resetting the phone but that doesn't work either. If anyone can help me resolve this, I'd really appreciate it. Does Apple have a chat or live help available?

Ugh! How to navigate when you have a dead Mouse / Trackpad or accidentally turned off bluetooth

Wow...
Did a stupid thing and turned off bluetooth on my Mac and watched as my Apple Magic Mouse and Apple Magic Trackpad dissapeared and left me stranded.
For those of you dead in the water unable to navigate your Mac here are some tips:
Reboot your Mac and Zap your PRAM which will force the Mac to turn on bluetooth again. Shut down the computer by holding the power button. Hold down Command (the Apple icon 4 leaf clover key), Option, P and R keys together and hold them all down after you turn on the Mac. If you do this before the grey screen you'll see the Mac chime and restart. You can now let go of your keys and see if BlueTooth can now discover your devices.
If you haven't already swapped out batteries in your Mouse, Keyboard or Trackpad please do so. Be sure to not mix batteries of different types in the device.
If you have keyboard access, but not your mouse or trackpad you can press the Option Key 5 times and then your numeric pad should move the mouse allowing you to navigate to things like System Preferences, Bluetooth to turn it back on!
If you have a USB mouse you can plug it in, navigate your mac and turn bluetooth back on.
If you have Apple Screen Share or Apple Remote Access you can use another Mac to log into your Mac and turn on bluetooth.
Serious Accessbility Feature Requests for Apple (and yes I know this isn't the forum or place to put this, but it needs to be said):
You need to go back and fix 10.8.4 to allow complete navigation of a Mac with a keyboard only. You can use Command + SpaceBar and type System Preferences and then type BlueTooth, but once you are in the Bluetooth settings you can't use your keyboard to navigate to the ON option.
You can't also navigate into System Preferences / Accessibility to turn Enable Mouse Keys (you need a mouse to turn this option on!). The Mouse & Trackpad options should be made so that a keyboard could turn on/off this feature, because a lot of people trying to turn on this feature are folks like me who lost mouse/trackpad access!!
Hopefully this helps others! Hopefully Apple will do some basic UI improvements to bring back OS navigation for users who only have access to a keyboard or just a mouse/trackpad (no physical keyboard). These kinds of tests should be part of every major OS release!

AppleScript to turn off Bluetooth after an hour of no usage

I'm interested in making an AppleScript that will turn off Bluetooth after a bluetooth device is not used for (let's say) one hour. The script should run only on battery life, not when the computer is plugged in.
Any ideas on how to start? Thanks.

I don't think there's any way (at least easy way) to do this.
AppleScript is very good at initiating events, but not good at responding to them. As such it's not easy to write a script in this manner. About the only way to do this would be to have a stay-open script that periodically checks the list of connected devices and keeps track of when the last bluetooth device was used - however, there's a big difference between being 'used' and being 'connected'... you may have a bluetooth headset 'connected', but if you're not running any audio apps it might not be used, and that's hard to AppleScript to determine.

How to completely turn off Bluetooth and Wireless

Hey everybody,
I'm running Windows XP SP3 via Boot Camp and I was wondering if anyone can assist me in how to completely turn off Bluetooth and Wireless connectivity so that I can reserve as much batter life while being in class taking notes without a plug-in source, but not uninstall. I know there is a Bluetooth control panel and I disabled it there but under "connect to" its still remains there. Basically I want to have the Bluetooth and Wireless turned off completely when I startup and still have the icons shown in the taskbar to let me know that they are still there.
Thanks!

Joergen Thomson, I can see that you have the same thoughts like I do, I wish they could release a software that is stable and better then this.
I dont have the energi or time to report all flaus back to cisco, this product have taking to much of my time and frustration already. Thank you so much for all the time you spend to try get this product stable and hopefully a good product.
I have a costumer that have a webservice that is IP restricted, For now I have to define more then 93 policys openening for the same service because this doesnt handle address list and groups. And all the times I had to set it back to factory default becasue of HTTP Admin server stopped, VPN Problem, Firmware Upgrades, "Packet Loss" and so on takes alot of time becasue I need to reconfig policies back.
For now to they release a firmware is stable I have take this piece off the network and put the back a old Fortinet 60 box.

Can't turn off Bluetooth

Just realized that I can't turn off Bluetooth on my iBook. If I go to the menu bar, the "Turn Bluetooth Off" item is dimmed. The "Turn Bluetooth Off" button in System Preference is also dimmed.
What's going on here? Can anyone help me out?

There are no bluetooth devices connected to this computer. As well, when I look in the Bluetooth preferences in System Preferences, it says that the Device Name is Unavailable.

Turn Off Bluetooth + Battery Life

Hey Everyone,
I am using XP Pro under bootcamp on a Macbook Aluminum 2.0 Ghz. I was wondering if there was a way to turn off bluetooth. Also, there is a major difference in battery life between Windows and OS X. In OS X I get about 4 - 5 Hours. Whereas when I'm in XP I get about 2 - 3 Hours. Is this normal?
Thanks.

Hi,
the differences in battery life between OSX and Windows are 'normal' !
The Apple Drivers for Windows lack the special energy savings feature that Apple has implemented with OSX.
To my knowledge the only way to turn of bluetooth in Windows is to use the Device Manager (Control Panel - System - Hardware) and deactivate the bluetooth device.

My wifi wasn't working for more than 10 minutes at a time after updating to IOS8 and resetting network settings. I turned off google drive, turned off Bluetooth, reset network settings and rebooted my iPad4. So far so good.

I have an ipad4. Wifi keeps cutting out after the upgrade even after I forget the network and resign on or reset all network settings. I deleted iCloud drive from my iPad, turned off Bluetooth, reset network settings, and rebooted my iPad. Since I upgraded to IOS8 this is the longest wifi has consistently been working for me. Which is approximately an hour now. Anyone else find that this worked or have figured out if this or anything out there is a permanent fix?

Hi CollinGCC78,
It sounds like you have been on the right track in troubleshooting this issue. If you are still having issues, you may want to double-check the steps outlined in the following article, in order if possible (apologies for replicating any steps you have already taken):

IPhone 5 will not be recognized by iTunes or charge while on but when turned off the iPhone will charge just fine but still won't sync with iTunes what should I do?

Was charging my iphone 5 for about an hour or so after charging unplugged and went to playing games phone was at 5% so I grabbed my cable and plugged it into the wall nothing happened tried three different chords and blocks and sockets afterwards I plugged my phone into the computer and it wouldn't charge or sync with iTunes it acted as if it wasn't even plugged in so I shut the phone off and though I'd give It a break and try again later. As I got ready to go to bed I though I'd try to plug it back in and see if anything happened nothing did so I just left it I went to mess with it this morning and come to find out it was at 100% I continued to mess with it and i came to the conclusion that it only charges when turned off. I can't get the phone to reset and would love to restore with iTunes if it would sync with iTunes I don't know what I need to do but really need my problem resolved since its a hassle to have to turn off my iphone in order to get it to charge

Is that a new iPhone? Bring it in to Apple for a replacement.
But do this first:
hold the Home Button and the Power Button at the same time, keep holding, ignore everything on the screen, keep holding until you see the white Apple logo appear, then let go and let it start up.
It should charge both when on and off, unless you connect throug a hub and there are current eaters also on the hub: connect directly to the usb port.

How to turn off Bluetooth adapter via command line or script?

I'm trying to write a batch script that will be able to turn on/off any connected Bluetooth adapters.
In the "Bluetooth Settings" window, how can I change the "Turn off Bluetooth adapter" setting via command line or script?
Due to my account not being verified yet, I cannot post a screenshot. I will update this thread as soon as my account is verified.

Should iphone 4 receive messages when turned off and display them when switched back on

should iphone 4 receive messages when turned off and display them when switched back on

It's up to the cellular carrier, but I believe most (if not all) will enqueue the messages when your iPhone is off.
So generally speaking, a few minutes after you turn your iPhone on, your messages should display. Similarly, your voicemails would arrive.

When turn off wi-fi, macbook pro stop responding

installed maverics on my macbook pro 3,1. every time when turn off wi-fi manually, computer stop responding, it then has to be restarted by long press on the power botton.

Wanted the solution to work, but there's no option to Sync this iPod over Wi-Fi option on my Touch.
Settings > General > iTunes Wi-Fi Sync > Sync Now
No option to uncheck to opt out of automatic syncing. The auto syncing can only be stopped after it's started.
Solution found by searching the web:
iTunes menu > Preferences > Devices > Prevent iPods, iPhones, and iPads from syncing automatically.

Charging iPhone 3Gs when turned off.

I have had my iPhone 2 days and I have realised that it does not charge when turned off. If I turn the phone off and insert the wire (wall plug or USB on computer) the phone automatically turns on and when I turn it off it doesn't charge. Has anyone got any suggestions as to why this happens or any ways to fix it. I'm new to Apple products so I would much appreciate anyones help!
Thank you!

If you plug it in while on, then turn it off, it should charge just fine (although you will have no indication it is charging, since it is off).
If you turn it off and THEN plug it in, it will start up. That's just the way it is.

Restart your computer while holding down left mouse key. That will eject the CD and your Mac will start as normal.
