After my MBP has been asleep (lid closed), when woken, it seems to reconnect to wifi for a few seconds (30 or so) and then becomes unresponsive. All indications are that everything is OK, but web browsing etc fails. By "switching wifi on and off" on the task bar, it then works fine until the next time it's woken from sleep. I have changed wifi router, and this issue has been evident for a year or so (so was on Mavericks and is now on Yosemite). It has the latest released version of Yosemite (10.10.3)

I have a Mid-2011 13" Macbook Air running OS X 10.9.2 (the latest version). When I wake my Mac from sleep, sometimes, the Wifi will fail to find my network. The network icon will display the connecting symbol. The only way to stop that is to turn off wifi and turn it back on, where it will reconnect almost instantly.  A video I made showing my problem:

I am looking for a quick way to sleep without closing the lid, or using the mouse.  If it matters, I have Lion version OS and a MacBook Air.

Is it possible to have a program starting automatically when I connect to a specific router, and having it stop when I disconnect from this router?  Basically I want a program to run while I'm at work (flexible hours, so I can't just have some sort of timer function) but not when I'm at home - or somewhere else.  I'm running: Macbook air OS X Version 10.9.4

My new MacBook Pro powers on automatically when the laptop lid is opened.  Can I disable it ? If yes, then how to do it ?

Is it possible to stop my laptop going to sleep when I close the lid?  GNOME 3.20, Fedora 24.    My laptop does not reliably wake from sleep.  (It happens to be a hardware issue... I think I basically killed it while trying to replace a wifi card.  But I want to keep using it for a while longer).

I tried to post to this thread  for if I understand their question I am having the same problem, but the answer option won't work for.  After suspend, the wireless is disconnected and the only way to get it to reinitialize/be recognized is to do a full restart.  At first I thought it was my gnome-shell (for lock screen disappeared there with 13.10), but when I switched to the default Ubuntu it's still doing it and it's kinda driving me nuts for I have to reopen all my files and browsers/tabs/windows every time. I don't know how to show the terminal stuff the above asker shows, but it sounds like the same issue and it only started with 13.10 upgrade a few days ago.   Any help would be much appreciated!!! -- Thanks so much, ser.

My problem has become pretty specific but probably pretty easy to solve. I've followed numerous guides on the internet to setup wake on lan and managed to get it working quite good although I still have one issue.  I can wake up my computer via LAN and even over 3G, but when I'm sending over 3G I can only send about a minute or two after I shut down the computer (might be longer), but if it takes much longer my computer won't boot.  The guides mentioned something about the router forgetting my MAC address after some time, but if that is the problem, should it work over a private network?, and how do I resolve this issue?  I've installed DD-WRT on my DIR-615 router. The computer I want to wake up  is running Windows 7 Ultimate.

My laptop sleeps randomly sometimes while working on it. I observed it is due to pressure of my palm over the palm rest. I've googled about that and found about lid sensor are involved in sleep mechanism when we close lid and now i am sure it's due to the same sensor(faulty) that this problem is happening. My laptop is Dell Inspiron 15 3000 Series 3567 I am unable to find about my Lid Sensor in book manual of the Laptop. Can anyone help me how to disable that switch entirely or where is the location of that switch. I've disabled the setting of sleep on closing lid. But that seem not to help me much. Problem occurance frequency has reduced but problem is still there. Now it takes less time like moments of second to turn back on from sleep unlike earlier. PS: I dont have virus on my pc so rule that possibility out.

For the last 1.5 years I've tended to put my laptop in sleep mode rather than turn it off. Recently I started to feel it's not as fast as it was when I bought it, even if I restore a fresh Windows 7 image (I made it 1 week after installing the system for the first time).  Maybe it's just an impression, I'm not sure...   Can it be a result of putting my laptop in sleep mode? What computer parts get worn down over time? Is there software to test if these parts are worn?

Been having some issues with the STA drivers from bcrmwl-kernel-source. While the drivers do function, they only seem to function after putting the laptop to sleep, by either closing the lid, or manually putting it to sleep, and waking it up. The laptop here is a MacBookPro7,1 (Mid 2010 13-inch MacBook Pro), running Ubuntu 17.04.  While the issue isn't bad enough to deter me from using the laptop, it is not an elegant solution, and I believe that there can be a solution found somewhere.  For reference, here are the outputs from the Wireless Info script for both before and after: , . Hopefully these are of some use. If you need additional information about the computer, I will be happy to answer.

Sadly, yesterday I've spilled some water on my MacBook Pro (El Capitan). Before you yell at me - it was closed, turned off and it wasn't a lot of water, the laptop was wet only on the top and under - not inside.  Today I've turned him on. At first battery wasn't recharging for some reason, but SMC reset fixed the problem.  At the first booting speaker was like talking to me, hard to explain but it was weird. Also only right speaker was "talking", despite the fact that only left side of the laptop was watered. Then there was no sound at all, not from the speakers, nor from the headphones. Also microphone's not working. USB ports are okay. The water was spilled from the left side of the laptop. I know this is hardware issue, and something's broken, but I want to be 100% sure. No it's not muted. I've also tried NVRAM reset a few times, but it doesn't fix the problem :(  There might be one factor, before spilling, my laptop "died" for the first time (battery energy ran off), but I doubt it's the case. (but hey, every info matters, right?)  It wouldn't be weird for me, if only left speaker wouldn't work, but built-in microphone not working is kinda weird in this case, isn't it?  I just want to ask you guys, what else can I check, before I'll be 100% sure it's dead inside?  I've plugged in external microphone - it's not working too.

Every time I close the lid of my Macbook Air, it turns off and I have to manually start it later when I open the lid again.  It also doesn't persist some of my settings such as volume level, desktop layouts (order of screens and which applications are full screened), and command line PATH changes such nvm's currently used node version.  Kind of a "you don't know what you don't know" situation. I'm not sure what to terms to use to search for this kind of behavior.  Edit: Adding some extra information as requested. I am on the following:   13-inch Macbook Air from Early 2014 Mac OS X El Capitan (10.11.6)   In System Preferences > Energy Saver > Battery, I have "Put hard disks to sleep when possible" checked and "Enable Power Nap while on battery power" unchecked.  I've looked through other potentially relevant areas of System Preferences and haven't found anything that works. I've done some Googling, but haven't found anything that is related and I'm unsure of what other terms I could use to search.  Edit 2: The issue seems to have been resolved. There's nothing in particular that I tried that worked, but it's resolved now. Thanks for reading and responding!

I decided to upgrade to 17.10 on my Thinkpad.  Now every time I try to shut it down via console or menu) or reboot it, it takes ages.  TTY gives me several errors connected to hung_task_timeout_secs, reaching from kworker, over networkmanager down to wpa_supplicant.  I tried reinstalling with different ISOs (daily-build from 2 days ago, beta2, and the rc one from today) and still get the same error every time.  Any ideas what could cause that issue? Right now I'm running 17.10 on two other, different PCs without any problems whatsoever.  EDIT: deborphan doesn't return any orphaned packages. I think I might have found something though. I decided to completely wipe the disc, including my dualboot windows. Reinstalled, and everything worked fine. Today in university the problem reappeared.  Now the interesting part is: I think it is related to my wifi. At home, during installation and after, I had it plugged in via cable, and had no problems at all. But with only wifi in university it reappeared. So I gave it a try and plugged in the cable again at home, and it works again. Removed cable, restarted, and the problem reappears. Wifi-Card is a Qualcomm Atheros.

A few days ago my MacBook Pro slipped out of my hands and fell onto the tile floor. The outside got banged up quite a bit and the Touch Bar no longer lights up but still responds to touches sometimes but not all the time.   Anyway, since then it will randomly restart every once in a while with a kernel panic. I have the log posted below and wanted to know if anyone could tell me what is causing the panic?

The aluminum Macbook Pro gives a mild shock when connected to a wall socket and charging. It only happens when I'm, for example, not wearing shoes or slippers and my feet are resting on the ground (i.e. by body is acting as a conductor). I contacted apple and I was told to perform the following steps:  Shutdown  hold ⇧+ctrl+⌥+power for 10 seconds  wait 30 seconds then hold ⇧+ctrl+⌥+R+power (Let the Mac reboot three times with that apple tone, then let go. The Mac reboots again.)   This did not fix the problem and I was not told what these steps were supposed to do. They have asked me to purchase a three pin version of the adapter and see if that fixes my problem. My last MacBook Pro was giving pretty severe jolts towards end of life. Hence a bit concerned. Question  Has anyone here experienced such a problem?  Is anyone aware of what the above sequence of steps supposed to do?  Also, will this damage the Macbook in some way?

My Magic Mouse is intermittently losing its connection to my MacBook Pro.   First the mouse becomes unresponsive and a few seconds later, a picture of the mouse appears on the screen wit the words "Connection Lost." Then about 10 seconds later, the connections is "magically" re-established, without any action on my part.   Any ideas on what this could be due to and how I can stop this? I have changed the batteries and they are brand new. My software is also up-to-date unless there is a special bluetooth update that I have to go get somewhere.
