WiFi can not turn on in Z470 (8 32-bit Windows)

I upgraded my laptop Z470 Windows 8 Enterpraise (32 bit). I downloaded all the drivers from the center of Support Lenovo Web site then I installed these drivers. I installed the new driver for Atheros AR9285, in Device Manager, I see that the adapter (Atheros AR9285) wireless works normally, but I can't turn it on. Usually, I can turn it on using Fn + F5, but in Windows 8, this command uses to set flight Mode don't not to activate the WiFi on / off. I checked in my BIOS system, the wireless adapter is enabled and the WiFI switch next to the Port of also card reader. What can I do for this problem? I can't exercise my project server without this active wireless adapter, I can't share Internet with my friends, families and etc. Please help me... I need your help... Thank you...

  • EliteBook 2530p. Can not turn on WiFi Windows 10

    EliteBook 2530p, Windows 10 home

    Ive just upgraded the machine above 10 win 10 with the help of this site. Everything works fine except one thing, I can not turn on WiFi.

    The orange LED on the touch screen under the screen and the front edge of the machine are both orange and when I try to use the touch screen to turn it on nothing happens.

    All other keys work fine so I don't think that's the problem. I don't know another way to activate the WiFi on this machine.

    The WiFi card is recognized in Windows 10 Device Manager and I have re-installed the card and made sure the antenna cables are properly connected.

    Anyone had similar problems with WiFi / Win 10 works is not on this machine model?

    Any help or advice appreciated.

    SOLVED

    I'm frustrated, trying to get the WiFi works because it is a machine I was in the process of selling and I had no user file to worry about, I decided to clean install Windows 10 and re - install Windows 7.

    I did this and load all nessasary drivers but no matter what I did the WiFi refused to turn on. I did several searches and HP Wireless Assistant who got the status of 'Wireless LAN' was OFF but the Start button is grayed out so I couldn't activate it.

    While remaining in the wireless Assistant I hit the WiFi button on the touch screen and a message appeared telling me to unplug my Ethernet cable. As soon as it is unplugged the button power on in the Wireless Assistant has become clickable and I was able to turn on the WiFi!

    So it seems that if you connect an Ethernet cable to this model of HP, the WiFi system is disabled and the only way for him help is by unplugging the Ethernet cable.

    I think I'm going to stick with Win 7 because I'm still not sure that the wireless card is supported under Win 10

  • Satellite L30-101 - it can not turn on

    Hello

    I had a Toshiba L30-101 given to me for my birthday in 2006, he initially had Windows Vista on it so because of problems with this program.
    I was later forced to get rid of this program and to install Windows XP, and I have not had a problem since.

    However, last night, I forgot to bring my laptop, normally I do not panic as it happens in sleep mode, and yet when I lift the cover (when I do this windows XP starts and allows me to reconnect my phone) I have met with a black screen, nothing has been loading, nothing has changed, I was faced with a black screen.
    I pressed the standby key and nothing happened, nothing happened even when I hold the button for a bit longer.

    I disconnected the battery, and although 2 green lights showed that I should be connected on the right, I was always with a black screen. I left him a little and he's always like now, only 2 green lights went and it seems that there is no life be it current. I can not turn on,
    I tried to reboot and nothing has changed.

    I don't know what to do as this has never happened before. I might add that, even if I changed the program for XP I didn't no problems with it for 2 years and a half, until now.

    Could someone help me at all?

    Hello

    Have you tried to remove the battery and the AC adapter? Remove the two, wait an hour and try again.

    If it doesn t work I think that there is something wrong with the motherboard. Maybe it needs to be replaced or another part.
    Therefore, you can contact the nearest ASP and ask for help.

    Good luck!

  • Can not turn on touchpad

    Just took the touchpad out of the box and recharge the battery for about 3 hours, but can not turn on the touchpad. The Center button flashes while load (it blinks left-right-left-right...) so there should be a connection and I guess the battery is charged. Tried pressing the power button / stop, button / stop + Center button and power button / stop + volume up and kept building up to a minute, none of these worked. Has anyone seen this problem before?

    After some research on the HP website, I found that flashing left-right-left-right to the Center button means battery too low, and when that happens Touchpad won't turn on. Charge of TP throughout the night and it turned on itself. It would be great if it was the little manual that came with the touchpad.

    Hope that this is useful for those who have the same problem.

    Please, in the future, remove all the verbiage above when you ask for a
    issue. It has nothing to do with your question.

    I appreciate sincerely any help for this.

    You are running Microsoft Security Essentials, AVG, Norton or McAfee?
    If you run one of those, she didn't have Defender. It's
    good, not bad. Not only is there potential conflict, but there is no
    reason to have both; essentially, they have something very similar
    for the Defender integrated and running both at once will hurt your
    performance and create the risk of problems that are contrary to each
    others.
