HP p077tx: missing in Device Manager Wifi adapter

I have a HP p077tx laptop and it is under warranty.

As for 2 months I have problems with wifi as my wifi adapter used will be unavailable after that I woke up my laptop from sleep. I mean the wifi was not simply disconnected, but there was no adpater wifi under the Device Manager list. Once I chose scan for hardware changes generally used to be back again.

But last Wednesday, there just no and now it is gone forever. Tried rebooting several times which did not help of course.

I thought the system restore using the windows system restore to a date before I had this problem. However, as the laptop starts again wifi was back and works normally as it used to. I have never put my laptop to sleep but just turned off. Next morning the wifi always worked and I thought that the problem has been resolved, but it was only before I put my phone back to sleep and later, he was gone.

I also tried to remove the drivers installed for it programs and features, but it does not allow me to uninstall them and jumped an error saying that it cannot be deleted. \update 65.

There is no option to uninstall the driver from Device Manager, as I said is not even appear in the list.

So I tried to reset the laptop and it's same thing happened for a restoration of the system. After putting the laptop on standby it wasn't everything again.

Help, please.

  • Satellite L500 - wireless network adapter is missing in Device Manager

    Hi guys, I have read a lot of discussion but not found a job of answer to my problem and yet, although this doesn't seem to be a common problem, so I was wondering if someone can help out me. Model laptop is L500-1VT. There is no switch on / off external WiFi.

    In short:
    -Awake portable sleep, already before his pan was connected to wifi, but suddenly had no connection.
    -Adapter doesn't not appear in Control Panel, so checked Device Manager. Isn't there. : S

    -Thought that maybe something has come loose? But then checked msinfo32.exe and adapter was seen here.
    -Read a lot of discussion about it being from PVAT with FCU, then followed advice doing reinstalls and uninstalling and reinstalling driver wlan (this being seen in lost msinfo32.exe.) Unfortunately, it did not work. Still not apparently visible to windows.
    -Fn + F keys never worked and after reinstall of the above programs still do not work.
    -Wireless is enabled in the bios.

    -However, and I don't know if it's the crux of the problem. * Wireless is DISABLED in HWsetup.exe. When I try to turn it on, it says reboot needed. If I do that immediately, or much later, I get a blue screen and memory dump.* so I'm sure it's a software problem.

    -J' also tried restores system and disks of microsoft repair. But I am at a loss about what to do now, so use my phone via USB WiFi to connect to MTAs.

    If anyone has any ideas, it would be great!

  • Envy of HP Touch Smart 17: HP Mobile Data Protection sensor missing in Device Manager

    I had a HP 3D drive guard error after installing drivers of devices in Device Manager in the control panel.  I looked on Google for answers and they said to find the right driver on the HP website, sp71811, uninstall the old drivers and install a new one for this laptop.  I did this and got an error DLL missing after restarting the machine.  You told me to uninstall again and reinstall and do not forget to restart after uninstalling.  The installation said it was incomplete, that the files were not completely installed.  I got an error message about a missing .dll file (don't have the error code now).  Something about a file stack error.  I went to the Device Manager and uninstalled the driver for the HP mobile data protection thinking can I reinsall that Device Manager but he removed the accelerometer.  Now I can't download HP 3D DG due to missing accelerometer.  How can I retrieve the accelerometer and the original problem with HP DG 3D?

  • CD-ROM/DVD-ROM missing from Device Manager, FRUSTRATED!

    I jumped on my computer today, to copy a disc in iTunes and found that Windows is for some reason, do not recognize my DVD/CD drive.  Now, the drive is very good; This works.  I put in a disc and it runs.  But that's all.  I go to Device Manager to see what is the problem and I find that the knot of READERS of CD-ROM/DVD-ROM is missing altogether.  -What happened?  If anyone can help (not you, Rob;) I already tried everything in your list of suggestions), please.  I would appreciate.

    DT

    Hi Dtorres,

    • What exactly do you mean by it works when I insert the disk?

    If the device is missing in the Device Manager, it may be due to hardware failure or if the drive cables are not connected properly. This can also happen if there is a damage in the drive cable, windows will not be able to detect the drive.

    However, you can contact the computer manufacturer to verify if there is any firmware that you can install for the CD / DVD player and if you can run a diagnostic tool for the material.

    You can also start the BIOS of your laptop and check if the drive is detected in the BIOS and post back the result.

    I hope this helps. Let us know the result.

    Thank you and best regards,

  • DVD bluray missing in Device Manager

    I installed windows 7 pro from CD-Rom. I have barely use cd CD-Rom so I did not notice that all of a sudden my DVD drive has disappeared in the Device Manager. When you insert a disc, it rotates but does not start. BIOS sees the optical drive. BIOS has been also updated. All drivers have been updated. Googeled solutions and delete some keys but that did not work. Also restored the laptop to the previous state, but the disc has not been and cannot be restored later. There is a problem on the HP site but also no results.

    Can't believe that the drive is dead, I installed windows from it.

    Do not want to reinstall windows, as I have to be perfect.

    Any who know this problem and have a solution?

    I have a HP 8760W (not "ban" me at the business forum. I bought the laptop not for or on behalf of a company)

    It works. New DVD's ok.

    Not happy at first when I received the replacement however. I ordered exactly the same model. When I received the new dvd player, it turns out that the front was different (higher) and a metal strip which is screwed on the disk and is used for mounting the drive in the laptop was different. So the new reader did not. Took do some MacGuyvering to get the new drive to adapt.

    But it worked, dvd drive is showing in Device Manager now, so happy .

  • Re: Drivers for BT missing in Device Manager

    Hello!

    I have a Qosmio G30 with Win XP MCE... A few weeks ago, I have reinstalled my system normally with recovery cd... Now, I noticed that when I want to use bluetooth, I find no sign of bluetooth technology and even without driver bluetooth in my device manager... I also tried to install battery bluetooth and bluetooth monitor but these utilities were functionless... I read a lot of discussion in this forum but you have not found a similar problem...

    as far as I know BT device is listed in Device Manager, of only if BT is enabled. To do this turn on WLAN using the WLAN switch (the WLAN led should be on). Combination of keys after you have made this BT activate using FN + F8.

    Can you please tell us what will happen when you do this?

  • PA: Uninstalled my webcam drivers and now webcam is missing from Device Manager

    Hello

    I had trouble with my webcam I decided to uninstall the driver to try reinstalling one from scratch.

    The problem is that now my webcam is still not displayed in Device Manager, so I can't access its settings to try to update the driver.

    It was a very stupid thing to do, and now I don't know what to do...

    Thanks in advance!

    Cecilia

    Hi Cecilia,.

    Unless you have already done, the first thing I would say is just to reboot the laptop and see if Windows RE-discovered the Webcam and load a driver for it.

    If this does not work, try to run the system restore to return the machine to a point in time before that you deleted the windows driver - see Option 2 below.

  • The monitor icon is missing in Device Manager

    Monitor-viewsonc vm2235wm; NVID 8600gt video card; 6750 cpu;
    After concluding an update of the software of ms on 09/09/09, restart vista. Boot vista system good to load the monitor says no signal and stops. Vista keeps going with the sounds of startup vista responsible for confirming. A made a forced stop and start in safe mode. Monitor now works. Go to the device, active graphics card Manager - said it was ok. There was no monitor icon in the list. Updated graphics driver while there and rebooted. Still no monitor. Vista restored one week before the problem - same problem. Removing graphics card and initialized using the graphics card integrated and faithful old crt screen and device manager says there is a monitor. Nvid uninstalled drivers, restarted with vista and a map nvid in loads of drivers, restarted - same problem. Bought the new 8400 graphics card and equipped - same prob. Reinstalled vista - same prob.
    There is no other program on this to clutter anything in System. At the most recent drivers, even mounted new graphics card.
    Help please.

    G ' Day Manasa P, problem solved! Unfortunately no you (not disrspect to you somehow). As I said no monitor icon in the Device Manager. Change the drivers of graphics for the standard vga drivers to fix the problem. reboot to normal. Device Manager should now list monitor. Load the drivers depending on monitor. Restart and load the drivers for the graphics card via Device Manager. reset. I hope that fixed the problem.
    Thanks for your help, realize looking at the list of problems you have hard time, trying to unravel the problems of other people. That good luck.
    Hope you can pass on my stationary and can save you time.
