• 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.

• 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:

  Is the vista 64-bit, that you have installed the software that came with the system or a version of windows?

  Before installing vista, have you checked if there are external devices connected to the system?

• T420s Windows 8 Unknown device

  I installed Windows 8 x 64 recently and installed all the drivers. I was pretty sure that all devices have been installed.

  I had a problem of power management of hardware before installing Windows 8 I was hoping was a software problem that reinstalling the OS would be in trouble. Turns out was not software, he had the main Board replaced under warranty. Even after the replacement of the main map, I was still enough course that I have seen that all device drivers have been installed in the Device Manager.

  But today, I notice an "unknown device" listed that does not have a driver installed. I often know it can be the TPM module or any other system device, but I have the TPM installed the chipset software driver and management authority. But there's always that unknown device.

  The only clue I have, as to what might be the device is under details, the "Hardware ID" property value is "root\sscbfs_storlib_bus3". A Google search brings nothing to this string. 'STORLIB' shows like it has something to do with storage, but I have the Intel RST driver (11,7 Intel) as well as to install the card reader driver. I can confirm that the card reader works fine too.

  What else could be this unknown device?

  I never understand what it is. But I uninstalled (not sure how you can uninstall it when it is not already installed) and it showed no upward again.

  Hello

  ACPI-> Advanced Configuration and Power Interface
  ACPI defines hardware and software interfaces that allow focus on the OS configuration and power management to enumerate and configure motherboard devices.
  For example: ACPI is necessary for the standby and hibernation mode.

  Now your question; the new BIOS has been updated and configured to using VISTA.
  It seems that VISTA was not compatible with the previous version of BIOS because the ACPI interface. Now you can install Vista on the laptop, but it seems that you need a driver. Possibly new chipset driver version might help. But as you probably know, the drivers are not available at this time. Unfortunately

  A problem I had was that I'm ill ' nt get the driver HP Ethernat to install, I worked around this by using a modem USB wirelles connection and downloaded the Microsoft Ethernet driver, that seems to work in contrast to the driver Ethernet HP.

  The other problem I have is that the Device Manager still shows a unknown device, and make a search on the HP site does not solve this problem. The details of the unknown device are as in the area of topic here above.

  Device Manager says no driver file is necessary or were shipped on this unit.

• 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.

• Driver DVD disappear from 'My computer' and 'Device Manager '.

  Vista HP Portable DVD player continues to disappear from 'My computer' and 'Device Manager '. Already tried Upper/LowerFilters.

  Hi, a few weeks ago, the DVD burner in the laptop suddenly disappearedmy computer (Windows Explorer).  The first thing I did was check theDevice Manager to see if the drive was there.  It was not the case.  Restarting the laptop did nothing.  Repeated several times, active Vista updates.  No change.  By checking the net, I tried to delete the Upper/LowerFilters in the registry, download it tool Microsoft fix , delete iTunes, do a system restore, to change all the parameters of thesleep and hibernation off and a few other things.  It appeared for the first time after that:

  1. Do a restore of the system for the first restore point.
  2. Remove the DVD writer.
  3. Restarting the laptop.
  4. Research of new hardware in Device Manager .
  5. Change all parameters of standby and Hibernate off. (I tried this method without this step first, but the drive disappeared after the computer went to sleep and woke up.)  Tried 3 times with the same results).
  6. Closing.
  7. Reinsert the DVD burner.

  On the next reboot, the DVD writer has been recognized and ended up in my computer and Device Manager .  No errors of any kind and no drivers were installed at startup.

  What has happened since then, in the last 4 or 5 days, is randomly disappears from thedesktop .  Usually after a few hours or more.  This time, however, it usually appears inDevice Manager after a search of new material.  No reboot required.  It will read from a DVD .avi files each time.  It has not been detected byDevice Manager maybe about 2 or 3 times, and after a simple reboot, it will be present inmy computer and Device Manager automatically after a reboot.  I read that the superior/UpperFilter mark has worked for many people, but for some, the problem returns.  In addition, many of the discussions on this question and proofreading are years.  It happened about 10 days ago.  Within 2 days before the problem appeared first, it was an update of windows, but also an update of iTunes.

  I noticed that I received this error when opening iTunes:

  "The registry settings used by the iTunes for importing and burning CDs and DVDs are missing. This can occur as a result of installing other CD burning software. Please reinstall iTunes. ''

  I have not reinstalled, no DVD player.  Uninstalled itunes again.  Since I finally got the drive to appear (using the method I described above), I did bother to reinstall iTunes because I particularly need it on this computer, worried that it may be the cause of the original problem and I wanted to see if the disc disappears again.  I did do it, however, let QuickTime installed.  Don't know if this could be a problem?

  I stumbled upon this suggestion, but I also had the same question as the next post, and I have not seen a response.  I don't know if or how I should try:

  Nikki,

  You can not go back if the restore points aren't there. Try to reinstall the IDE driver.

  To do:
  -Click on the round to start and right click on computer
  -Left click on properties, this will open the system window
  -Click on device high Managerin left
  -Click on continue if prompted by UAC
  -Goto the 'IDE ATA/ATAPI controllers' you should right click on uninstall and restart

  BTW that dog rox in this avitar

  See you soon! MCP. MCDST. LVL 80

  Hi, thanks for the comment on my puppy. She is now 5 MB and her name is Nikki, lol.

  Well, I tried what you said, but the IDE ATA/ATAP controllers has a (+), so when I select it does give me not an option to uninstall. It is for me (analysis of the physical changes (or) properties).       and if I click on the (+) sign I have 4 different options. 2 channels IDE, Intel (R) 82801 HEM / HBM SATA AHCI controller and Intel(r) ICH8M Ultra ATA Storage controllers - 2850.

  http://social.answers.Microsoft.com/forums/en-us/vistahardware/thread/e3701d75-9dbe-4ae9-9d70-83f14129247c?Prof=required

  What I see in "Device Manager", under IDE ATA/ATAP controllers is:

  IDE channel (x 4)

  Ricoh Memory Stick Controller

  Ricoh SD/MMC Host Controller

  Ricoh xD-Picture Card Controller

  Controller of PCI standard IDE dual channel (x 2)

  The laptop is about 2 years and never had problems.  The DVD burner is hardly used to burn, maybe a total of 5 disks in this time.  It has been used occasionally to read or copy from, but not much.  I'm not convinced that he is dead, as I had 2 die on me in desktop computers, after burning hundreds of CDs in them and read much.

  in any case, I was not able to find any bugs or suggestions (with the exception of 'replace' the reader), so I just wanted to describe my specific situation and see if anyone could help out.  Forgive me for information, I have left out, but I am an amateur when it comes to the problems with the computer and still don't know what mean things or where I can get information on my OS, software or hardware.  All anyone can do would be greatly appreciated.

  This is the information I have:

  HP Pavilion dv6700 Notebook PC

  Optiarc DVD RW AD-7560 ATA Device

  Vista Home Premium

  Service Pack 2

  Thanks again for any help.

  Hello

• Update blackBerry Smartphones / Device Manager issue

  Hey guys, I have a problem.

  I recently acquired a Blackberry 8330 and let me start by saying this: it's one of the best machines I've ever held. It is simply amazing.

  I installed the Device Manager and have been using it without any problem. Then, I went and did an update wireless with my phone, the upgrade of the OS. Since I did this, however, the Manager has recently stopped recognizing my device - my computer recognizes him again, as he charges when it is plugged in and I can always access to the hard drive, but for some reason, I cannot use the Device Manager to do anything - down, States in the Device Manager there is no trendy Black Berry as shown by the 'None' exposed next to the Pin number.

  What can I do? I really need to access blackberry via the Device Manager. Someone, please help > _

  Things I've tried:

  -Restart the Blackberry (both by pressing the red button and pull the battery and re insert)

  -Update the device to the more recent version Manager

  -The latest version is uninstalled, then download and install the version provided with the blackberry (4.2)

  I noticed that the CD that came with the device itself does not contain the most recent edition of the Device Manager, if that means anything. It's just weird that the Device Manager has stopped working after I upgraded. Currently, my OS is V4.5.0.175. I've recently updated both my 8310 Black Berry - same question parents. Before, I could access it via Device Manager. Now, I can't. Please help me!

  -Santos
