• 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?

  Hello:

  Try the latest version of the 3D driveguard driver...

  This package provides the software HP 3D DriveGuard to the notebook models that are running a supported operating system. HP 3D DriveGuard software protects the drive hard by parking the heads if cell phone accidentally falls, or is suddenly struck by another object.

• Satellite C650 - USB ports not recognized in Device Manager

  When I turned off my cell phone, I lose the use of my two USB ports. The only way I can get back them is to use Device Manager

  Go into the Manager of peripheral devices, Bus USB controllers, there are 6 x Intel ICH9 Family USB Universal Host controller 2 x Intel ICH9 Family USB2 Enhanced Host Controllers and 7 x USB hub root. When I lose the USB ports, USB root hubs seem to disappear, and the only way I can get back them is to uninstall the controllers and then right-click Universal Serial Bus Conrollers for "scan for changes on the hardware. This brings back the root hubs and USB ports work fine... until the computer turns off again.

  Someone at - he encountered this problem and managed to resolve it? Its a hassle to have to go through the uninstall it / Reinstall procedure each time. Your advice will be appreciated.

  Hey Buddy,

  You use the version preinstalled Windows from Toshiba or did you install your own version? I don't see any information about the BONES in your ad...
  Theoretically, it could be a software problem so ports USB work correctly if they recognized in Device Manager

  You should also try to update the Web from Toshiba site chipset driver. Maybe it helps.
  Otherwise, I could imagine that the update of the BIOS can also operate and this update you can get on the Web from Toshiba site too.

• 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!

  Hello

  WLAN works when you restart your laptop?
  Latest version of the BIOS is installed on your laptop satellite?
  Have you tried updating the BIOS too?

  And Yes, last question: do you use the original OS that you got with your laptop (recovery image)?

• 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.

• 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,

• 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?

• 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.
