• P 8470 & HP HP 8440 P: upgrading to W10 Pro 64 bit / device Reporting - unknown device manager

  I have recently upgraded to Windows Pro 64-bit 10.  Machines involved are - 8440p & 8470p running W7 Pro 64-bit.

  The Device Manager shows an unknown device - ACPI\HPQ6000\3 & 33FD14CA & 0.

  Could someone tell me what this is in reference to.  Perhaps point to a driver that I could update.

  Thank you / / Jeff

  You are the very welcome.

  The reason why you don't see the driver is because most of the drivers are missing in support pages, which have not worked directly for HP split into 2 companies from 1 August.

  This is certainly the driver you need.  If the version of W7 works, I can't say.

  See if it works.

  FTP://ftp.HP.com/pub/SoftPaq/sp59001-59500/sp59282.exe

  If this driver does the same thing...

  Go to Device Manager and click on the unknown device of 6000 who need pilots.

  Click on the driver tab, click on set to update driver.  Select her browse my computer for driver software option, then at the bottom of this window, let pick me from a list of drivers for devices on my computer.

  Click on disk and go to C:\SWSetup\sp59282\accelerometer and select the HP Mobile Data Protection sensor and see if the pilot goes like this.

  Here's a partial copy and paste of the accelerometer installation information file.

  As you can see the device is supported by the driver.

  But it's the most recent driver is there, I know.

  Mfg % = HP, ntamd64

  [HP.ntamd64]
  DeviceDesc % = HPAccelerometerDriverInstall.ntamd64, ACPI\HPQ6000

• CD player does not install (virgins Adobe Download Manager)

  I tried several times to install the drive on this laptop Windows 7, without success. (edit: I finally got version 10 install correctly, but won't work or 11 or DC).

  I tried the things:

  UAC is disabled, the disabled, tried to run the installer as administrator (its an Admin still counts). Cleaning of all older versions, used uninstall reader I found, used CCleaner to check for errors, run SFC, etc.. No difficulty to install Flash, Air, or Shockwave all went well, fair reader with questions. This machine is Win 7 Home Premium, 64-bit

  I can see the process is running, but it's just sitting there with nothing happens after 1/2 hour.

  If I try to install the DC version, it opens the window "Adobe Download Manager", which is just a blank window, nothing happens.

  I tried to download it directly from the web page, the offline version (Adobe Acrobat Reader DC install for all versions ) of 11 and DC, and always the same problem - the installation IS running, but it does nothing.

  Any other suggestions?  Thank you!!

• Portege M200 - device unknown in Device Manager

  I did a clean install of Windows XP on my toshiba portege m200 (Tablet). I have most of the devices drivers installed, but there is one that I can't understand. The device manager says I have an "unknown device" on my "Intel 82801 dbm lpc interface controller.

  What is it? I thought it was the chip set, but I had installed the Intel chipset drivers (twice, just to make sure that I really did), but it still reads as 'unknown device' on ' Intel (r) 82801DBM LPC Interface Controller - 24CC.

  To resolve this issue go to the device, right click on the unknown device, Manager and then select set to update driver.
  When the Hardware Update Wizard appears, select the advanced option.
  From the next window, select the 'don't search. I will choose the driver' option
  Now, go to the Intel announcement and select good "82801DBM LPC Interface Controller - 24CC.
  Click OK and now it should work.

  Also, be sure you have all the drivers installed from Toshiba Web site:

• Re: Satellite 5200 701: unknown device in Device Manager.

  Hello.

  It WinXP Pro + SP 3.
  In the display devices, such as an unknown device manager. Try all of the pilots, who were on a disc with the laptop, nothing helps. Give the solution!

  I still use Windows XP Home with Service Pack 2 and I'm really happy with it. If you have some problems with SP3 remove and continue to use Windows XP Home with Service Pack 2 only. Satellite 5200 is quite old but very nice laptop. Make sure that the laptop works fine with SP2 and you have an application of good-antivir.

  Simply to operate Satellite 5200. I noticed that many people have reported on various issues after installing SP3. Exactly the same thing with Vista SP1.

• Satellite L650-1NC - Map disappeared WLAN Device Manager

  I bought the Satellite L650-1NC. After installing the system, everything is ok, but no wireless card. I downloaded the latest drivers from Toshiba and manufacturer sites. After you have installed the latest drivers for the wireless card disappeared from the Device Manager! Connection via cable, works without problem. Exhausted all ideas. Help, please.

  PS. Sorry for my English

  Hey,.

  The WLAN card is listed in the device as unknown device manager or it is completely gone?

  It's probably happened due bad installation driver in your case, I recommend removing all WLAN drivers and run CCleaner tool to clean the registry. Then download & install the latest official Portal WLAN WLAN drivers:

  Also, make sure that the wireless network adapter is enabled. This can be done with the FN + F8 key combination.
