My computer will work for a while and then it powers off.

I have a macbook pro.  Just today I have had problems with it all of a sudden powering off and I have to restart it.  When i do, it does it again.  I have updated all of the updates but I have never had this problem and don't know what to do.  Has this happened to anyone else?

  • My PowerBook G4 says that it's connected to wifi, but it still no internet connection. The connection will work for a while, and then I'll have to run diagnostics and it will work again for a few minutes and then stop working again. What's going on??

    I have been unsuccessfully trying to extend the wifi of my Time 2T Capsule with an Airport Extreme 2nd Gen. It works for a while and then loses configuration. I have done everything possible, disconnected it, reset it but it keeps failing, what to do?

    What model and firmware is the 2TB TC?
    What firmware is the AE?
    Does the AE get good signal from the TC in its current location?
    Signal can only be extended that is received intact.
    Is it extending on 5ghz? As I remember it a Gen2 AE is only single band, although you can choose either 2.4ghz or 5ghz.
    I am fairly sure you are going to tell me your TC is AC model..
    I would do a couple of things..
    1. Fix the wireless name, make it short, no spaces and pure alphanumeric.
    2. Fix the wireless channel for 2.4ghz so it is not going to jump around.
    3. Get real results from the AE in its current location for signal strength.. this is really only possible on v5 utility. And that is a double pain with Mavericks because you cannot use it.
    Apple have removed all the useful diagnostics from the airport utility. There is next to nothing left. So you need to use the computer and its diagnostics to find signal levels in the location.

    In addition, do you get a certain error message when your WiFi stops working? Have you verifed that Auto Switch network is disabled? To disable this setting simply to go Settings > Wi-Fi > Tap the Menu Key(to the left of the home button) > Select Advanced and it is called `Auto network switch.

  • Airport Express that works for I while and then quits

    I have an airport express that I connect with an Ethernet wire to my wifi network base station to be able to extend the wifi to other areas of the house. It used to work perfectly and I had the green light on it for days and days on, in fact it never quit it could be on for weeks.
    Now it works for a  while, an hour or so, and then the light goes out completely (no orange light, just no light) and there is no longer any wifi communication. Is the Airport broken or could it have something to do with the originating wifi provider base station which is in fact hardwired to the the Express?

    Now it works for a  while, an hour or so, and then the light goes out completely (no orange light, just no light) and there is no longer any wifi communication.
    Unfortunately, this is a sign that you are likely going to need to replace this Express.
    Here is what I think is happening based on experience with these devices:
    The internal components on the Express heat up significantly and after an hour or so, the heat build up is causing a weak electronic component to change in value, or heat expansion is causing a loss of an electrical connection at a tiny solder joint.
    When the device cools down, it will work again for awhile, but the same pattern will likely repeat. Internal repairs on the Express are not really feasible since the labor costs will likely exceed the cost of a new Express.
    If you are really handy with small electronic repairs and you have the time, you could carefully saw the case open along the center seam to open up the Express and take a look at connections and solder points. It 's unlikely that you will find something obvious, but might be worth a shot.

  • Bluetooth Mighty Mouse - right click works for a while and then stops...

    I recently bought a wireless Mighty Mouse, installed all the supplied software and paired it with my Macbook Pro. I've set up the right click as Secondary button and have been using it without any problems.
    Then recently I've noticed that after using it for a while (in general applications like Aperture, Firefox etc), the right click will perform a Primary (left) click instead. Even if I take my hand completely off the mouse and click on the right side, it will perform a left click function. If I switch the Mighty Mouse off and back on, it starts to work normally again.
    Is this a general issue with these mice? Or is mine just faulty? I can't see that it's a hardware fault as it returns to normal when I turn off/on the mouse. Any ideas?
    Thanks in advance.

    My new MacBook Pro and Wireless MM just arrived Friday and I spent Saturday transferring files from my PB G4 and installing Parallels/WinXP.
    My Mighty Mouse worked fine initially, but then the Right Click (Secondary) reverted to Left Click (Primary). I reversed the settings to a "Left-handed" setup, the settings stuck. But the right button would not hold a Secondary setting.
    I then paired the PB G4's Wireless Mighty Mouse (that I've had for several months) with the MacBook Pro - same issue surfaced. Both mice work consistently as represented with the PowerBook AND my IOGear bluetooth mouse works perfectly with both the PB and MBP (although the Mouse Preference Pane that comes up for the IOGear mouse is a reduced feature set that does not allow any additional button programning.)
    I think it's a Preference Pane code issue. If the others who have posted here have ALSO installed Parallels, then the Parallels tools may be creating conflicts.

  • I am a new mac user and have a 15 macbook pro (non retina display).  I am having an issue with safari "freezing" ...it will work fine for a while and then I will open a new tab and attempt a website that won't load and after that it seems no website will.

    So yes like mentioned above...i am a new mac user...have only had it about four days and have had a windows based system always before this.  The issue I am having is that I will be in safari and it will work perfect for a while and then i will open a new tab and attempt another website and it will either be extremely slow or will give the error that it cannot connect to the server, however, when i run diagnostics my internet is fine.  The only solution i have found is to reboot and geeksquad has been unable to replicate the problem while connected to my computer to try to do so.  Does anyone have any suggestions or anyone else with this problem?  If you have a "fix" please try layman's terms because again I have no idea about macs haha.  Thanks,

    im using an iphone 4s with the latest firmware which is 6.1.3 but my wifi button keeps going grey how can i fix it? i rested network connections and it worked for a while and went grey again,what can i do?

    Have you worked through the Troubleshooting iOS and WiFi knowledge base article?  If not, see if there is info in there that might help.
    Is the WiFi greyed out on all WiFi networks or just the one?  If it does this on all then there may be a hardwaer problem that needs attention from the techs at an Apple store genius bar.
    Before that, however, try a reboot by holding both the power and home buttons until the apple logo appears and it restarts, ignoring the red slider if it appears.  That clears a lot of iOS hang ups that occur.
