  Have you installed the driver WLan?
  The laptop seems to be equipped with the Atheros AR9285 WiFi card and in most cases the Fn + F8 key does not work because the Wlan driver is not installed or is not working properly.

• 3/4 USB ports cannot connect/charge iPhone/iPad

  I have an iMac 27 '' new. When I try to connect my iPhone or iPad, I have this problem on 3 of my 4 usb ports. The devices are sounding as if they connect, but continue to do so and therefore don't actually connect, load or let iTunes sync. "ding, ding, ding, ding, etc...". "I normally use Apple cables that work on my other computers or when it is plugged into the wall outlet, it is not the cables. My iPhone has the new cable and my iPad is older with cable connection/old - they both have the same problem. The first port seems to operate normally.

• USB ports stopped working unexpectedly

  Hi, I am currently on "Toshiba Satellite C655"run"Windows 7 Home Premium". It's a laptop of 2009 model (2 GB). Last night (24/02/14) my USB Ports stopped working, they have been and continue to read anything every time I have to plug my devices. I usually only connect a cooling block and a USB mouse to the computer. They worked perfectly until I disconnected the. When I reconnect them, they work momentarily, and then I hear the beep sounds when you eject a device. I tried to connect several flashdrives, a printer, and one I tried the following hotfixes:

  Note: The order of numbering has nothing to do with the order, I tried to apply each patch unless specified elsewhere. This computer had Windows 7 Home Premium REINSTALLED at some point. Just for your information. This message was made when there are others with the same problem is due to the fact that no solution not specified by Microsoft Technical Support or the Microsoft community were effective.

  1) System Restore to the last known point, where they worked (and still). (Point restoration @ 15/02/24)

  2) Windows Update

  3) turn off the computer, disconnect the battery and the power supply and holding 'On' button for 10seconds.

  (Note: whenever I turn on the computer now they work only for a moment, usually from 60 to 180 seconds.)

  (4) Start > research ' Device Manager '> "De Bus USB controllers" Expand and turn off and restart the computer. They are re - activate automatically but my problem persists.

  (5) download and run "Microsoft FixIt.WinUSB... ", on the 1st, I had a problem with devices not updated. But I actually watch updates by using Windows Update and ""searching for hardware changes "" on USB Bus controllers "." I then did a 'System Restore' and now Microsoft FixIt found no problem but the USB Ports don't always work.

  (6) will ' services.msc"and change the Startup Type of Manual to Automatic for Windows install and restart Windows."

  7) regedit

  8) sfc/scannow

  I am really lost with this problem now. My laptop works and worked perfectly fine until this problem occurred. I have fixed minor problems with computers before, but this is a bad joke for me now. If someone could please help me with this problem I would appreciate it a lot. Thank you very much.

  Thank you for your help, but I discovered something funny on my computer. My cooling package (product name: Laptop Cooling Pad NSB;) HYCF-6181-2 model number) is to disable my USB ports when I plug. If I leave it unplugged and restart my computer, my USB mouse is still working on a port. Also tried using my USB and other devices. The problem is my block of cooling that strangely disables my USB ports, whenever I plug. Thank you very much for your quick response, fortunately the answer might help me in the future. For now, I have solved my problem.

• Turning off the current excitement of SCC-RTD01

  I have an extensometer which has 4 wires instead of two. The reason why I have four sons is because to each pad, I a chromel and alumel wire to create a thermocouple. This way I can measure the temperature right at the gauge (two TC by gage).

  I need to measure the resistance of the gauge that I change the temperature. I have a module SCC-RTD01 can I use to measure the strength of gage (I did actually and it worked). But since this module puts a 1mA current excitement, my reading of thermocouple is false (because the current passes through at least one of the sons, creating a tension which is not pure the thermocouple voltage).

  Is there a way I can turn the excitation current LabVIEW? Alternatively, does anyone have another suggestion? Thank you.

  Hi JG001,

  Thank you very much for clarifying the issue, I now understand your request.  The fact of the matter is really that the excitement is broken out to its own terminals dedicated; It cannot be turned off, and in the Manual of the SCC-RTD01is. You can also check this by entering a 0 my in your task to the excitement and you will find that this is not a supported value, only 1mA is a supported value and it will throw an error, as shown below.  I've also included a few screenshots from the manual that describe it.  The excitement can be disabled, 0mA if a value supported for the current level of excitement.  I hope that this clears up any confusion.  A possible solution would be to use a relay to activate this, perhaps the SCC-RLY01.

  

  

  

• Accelerometer turns off when the screen is off

  When testing my application on a Z10 android port the accelerometer turns off when the screen is off. A partial wake lock does not turn the sensor back on. A wake dim screen lock is needed to re - turn on the detector. This behavior forces the screen to be all the time when an application requires the use of these sensors.

  An example would be a pedometer recording the steps throughout the day. In order to operate the screen must be turned on by the application that runs in the background. This will cause a fast draining of the battery and is not an acceptable solution.

  On Android, a partial wake lock is enough to keep the accelerometer running.

  I think this should be reported as a deficiency, a lot of motion carried since Android applications will be blocked by this and my app port is one of them.

  Tested on system Z10, model number STL100-3. Version of the 10.1.0.273 software

  The fix will appear in MR 10.2, 10.2.1 aka.

  I recently submitted a fix for the problem.

• Keep the power to the USB port after stopping down?

  I would use one of the USB ports to plug in my cell phone to load from one day to the next off the computer. What are the steps to follow to set computer to keep providing power via USB ports after shutting down the computer?  I'm a novice so need to know where to find the place that controls the settings and what to click on. Thank you!

  If you put the computer in Standby Mode when you stop, the USB ports are not powered off.

• Unable to turn off the Magnifier in Win7

  original title: I made every effort using all the instructions I can find to turn off the Magnifier in Win7 and none of them worked.

  I'm unable to turn off the Magnifier in Win7 and asked help available to all sources known to me. I was told to use the ease of access and uncheck Mgnifier.

  Because it did not work.
  Then I tried to use settings in the mouse - did not work.  And there are other approaches - none worked!
  I guess the Magnifier is useful for some, but for me, it's a major nuisance and I would definitely find an approach that would disable it permanently...
  E-mail address is removed from the privacy *.

  I'm curious now. Do you want to say its always active and cannot be turned off, or it appears now and again when you don't want or need?

  Maybe these posts can help?

• USB port on V3 - 574 G turns off after stop

  Hello
  I noticed that one of the two USB3 ports on my laptop continues to hold power even after that I stopped it completely. Thus, an external hard drive connected to it will continue to run as if the phone was on. Moreover, the port seems to work fine. Is this a normal behavior?

  Thank you.

  Looking for Acer quick access to your programs, should also be an icon in your taskbar. There is an option to turn on or turn off power to the 2 port USB 3, when the computer is turned off. It is a function to load other devices off the 2nd port usb3.

• Belkin F6D4050 v2 USB Wireless Adapter turns off after 5 minutes using Windows 7 Home Premium 64 bit

  I recently bought a wireless adapter Belkin for use in my Media Center PC in the living room. The router I use is also a Belkin N + Router. The wireless adapter will connect to my WPA encrypted network, but it will stop working after about 5 minutes or more. The State of the connection is going to say "No network detected." The icon shows a strong signal with a yellow bang next to it. It takes a hard reboot to get it working again. Take out the USB port and put again does nothing. The icon remains the same, but he won't let me not make a right-click or left-click on the icon. When you try to stop, the computer turns off completely; It gets stuck on the "Shutting Down" screen.

  I disabled the option in the settings to get to power adapter down to save power. I thought that this would fix it, but still the adapter is not connected.  My Dell laptop gets a signal stronger than this card, and there is also no problem to stay connected to the router.

  Any help would be appreciated on figure out how to get the card working properly.

  Hi brutus09,

  Welcome to the Microsoft Answers site!

  That the connection is lost intermittently, the issue seems to be with the drivers.

  4. using another PC or via an temporary Ethernet, download the latest driver from the link above.

  5. run the executable downloaded on the computer, connect the adapter when prompted target.

  6. connect to your wireless as usual. If you have an encryption key, you will need to enter again by reinstalling the driver should solve the problem

• Last Firefox update turns off my USB2 ports.

  My laptop worked fine, but then I hit a problem because my USB2 ports won't work; My USB3 ports was working but not 2.

  I tied everything back to the 16 June when I installed the latest Microsoft and Intel Graphics update. Right now I've also updated Firefox to the latest version.

  I couldn't solve the USB2 problem so did a restore of the system around June 12 and everything worked fine. I put the USB2 problem down to the Intel updated and reloaded all Microsoft patches and everything worked fine. Then I upgraded to Firefox and restart my USB2 ports do not work. A few minutes ago, I completely uninstalled Firefox, restarted the laptop and the USB ports are working fine again.

  I guess that the last Firefox creates a conflict somewhere but where so I was wondering if someone might be able to help the goodness.

  My system is running Windows 8.1 64-bit and I loaded Kaspersky Internet Security. As I said, everything was going fine until I updated Firefox with the latest patch. With no Firefox, now I had to Windows 11 as default.

  Thank you.

  Steve

  Thanks for the suggestions - tried all that and v30 still knocks my USB2 ports.

  I read on the Internet about other users lose their mouse touchpad once v30 has been installed, so I guess that Firefox is somehow contradictory in a way with particular laptops; mine being one of them.

  In the end I found a link that allows me to install v29.0.1 and after having turned off the automatic updates, all is well again. I think I'll try an update again once us get around to v32, but in the meantime, I'm happy to stay with v29.0.1.
