What you need is the ACPI ( advanced configuration protocol interface) driver for the installed CPU. You can get that at the processor manufacturers support website. Intel's download center is here.

HP Elitebook Folio 9480m drivers missing / Device Manager PCI Device and Unknown device?

Hello all, I have already installed Windows 8.1 Pro x64 and i have on the device manager still 2 missing drivers they are PCI Device and Unknown device??
Please see attached a printscreeen. ANy idea which drivers are missing? Thank you all

Hi: You need this driver for the PCI device... http://h20566.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=7089928&swItemId=ob_134503_1&swEnvOid=4158 I gave you the driver for the unknown device when you had W7 on the machine, so it is probably the same one. http://h20566.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=7089928&swItemId=ob_132986_1&swEnvOid=4158 If it is not that one (or you had two unknown devices at one time, and already installed the 3D driveguard driver), then it is probably this one... http://h20566.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=7089928&swItemId=ob_133322_1&swEnvOid=4158

Hello Eng_MG
I see that you are having problems with the finger print reader on your HP computer.
I would suggest posting this message in the HP Commercial Forum as well. There will be more users with the same computer and programs. The link will take you to the board specific for your computer.

HP Probook 4540s upgrading RAM

Hi,
I would like to upgrade my memory (4GBs are not enough in theese days) for probook 4540s
Now, I have 1 module with theese specifications:
CPU-Z:
DIMM #               1
   SMBus address       0x52
   Memory type       DDR3
   Module format       SO-DIMM
   Manufacturer (ID)   Hyundai Electronics (AD000000000000000000)
   Size           4096 MBytes
   Max bandwidth       PC3-12800 (800 MHz)
   Part number       HMT351S6CFR8C-PB
   Serial number   (Personal information removed)
   Manufacturing date   Week 38/Year 12
   Number of banks       8
   Nominal Voltage       1.50 Volts
Question is:
Can I add newer model to the second slot?
I want to buy:
HP SO-DIMM 4GB DDR3 1600 MHz Unbuffered
Certificated for PC3-12800 (B4U39AA)
It seems, the new model of ram module should be compatible with my notebook, but will be compatible with my old module, while working on 2x higher frequency?
Or I have to buy 2 new modules and replace the old too?
Or I missed something and it is not compatible in any way?
Also, I have red at other forums, that upgrading memory up to supported 16GB takes some performance issues. Is it still ture, or is this already fixed?
Thanks for answer

Hi ,
The model supports the following specification of memory.
Standard
DDR3 PC3-10600 SDRAM (1333 MHz)
Two SODIMM slots supporting dual-channel memory.
2GB and 4GB SODIMMs
Maximum
Upgradeable to 8192MB with optional 4096MB SODIMMs in slots 1 and 2.
Dual-channel
Maximized dual-channel performance requires SODIMMs of the same size and speed in both memory slots.

Equium L10: Windows Vista Beta2 - unknown device

Hi
I have a Toshiba Equium L10 with Windows XP loaded as default but I installed VISTA Beta2 "public release" on it and given that it's only a 1.5GHz Celeron CPU with 512MB RAM, it ran extremely well but, I have one problem which I am hoping that I can get help with from the users in this forum and especially those who have the same/similar Equium model as I have?
Ok, after installing VISTA I checked in Device Manager and noticed "Unknown Device". After checking out the info given in it's properties, I have detailed it below:
Location: Microsoft ACPI Compliant Embedded Controller
Value: ACPI\ACPI 0001 * ACPI0002
When I re-installed XP again, I went to Device Manager/Batteries/Microsoft SMART Battery, the entry for Microsoft SMART Battery Subsystem has "ACPI\ACPI0002\6&28CA2229&0".
Notice the "ACPI0002" info given for the 'unknown device' in VISTA is the same info given for the "Microsoft SMART Battery Subsystem" in Windows XP. So I am left wondering if the unkown device under VISTA is the Microsoft SMART Battery Subsystem and if so, why did VISTA not install the driver for it?
Can anyone help with find a driver for the "unknown device" in VISTA?
Regards
Brave

Hi
The unknown device appears because the driver is missing.
Unfortunately, at this time you will not find any Toshiba supported drivers for the Windows Beta2. This is a beta version and not official on the market.
I think if this OS will be official supported so you will also find the needed drivers.

USB Ports - Mass Storage Devices - Unknown Device

Model: Satellite A135-S2276
OS: Vista
I recently tried plugging in my media card reader that I've had for several years now and has worked many dozens of times. Windows responded with an 'Unknown Device' response. I thought this was odd, so I changed and tried each USB port. To no avail the device wasn't recognized. I tried it in another computer and it worked fine.
I began to try two other mass storage devices that I know used to work, up until recently, on the laptop. Both now are 'Unknown Devices'. I now have a strong feeling that someting was wrong with windows vista. So I search around and find methods to force the driver (inf) cache to reset which should reload any corrupted drivers. Tried many methods, nothing worked, same results. I saw that Vista Service Pack 2 just came out, I installed that hoping that it would fix. Nope.
I gave up on it being a software issue after I did a fresh reinstall of the OS and with the base OS with no other software installed same results.
Is there a way to diagnose if the USB is malfunctioning from a hardware standpoint? Is it possible the USB, even thought windows recognizes it, is dead on the motherobard? If so, how do I get this fixed? Motherboard replacement?
Help!!

It sounds like it is working enough that it can recognize that soemthign is plugged into it.
You say you did a fresh install of Windows. Did you use the recovery disk or a retail Windows copy. If oyu didn't use the recovery disk then maybe you are missing a driver. Best woudl be to use the recovery disk. If a USB mouse doesn't work after that then the hardware has an issue. Assuming the BIOS is OK.

Lenovo G500: unknown device

Hello,
i have new g500, win7 64 , and have problem with unknown device in device manager.
can u help me pls.
properties say " root \ lenovoVhid ".
thx
Moderator note: off-topic post moved to its own thread. Subject edited to show content. Was: Re: Lenovo -G-500

Hi Preko.
I assume device manager showing a driver missing, If so right click it then click properties then update driver tab.
You may want to visit lenovo`s website & update all drivers for your laptop.
Also make sure you have the latest version of Lenovo soloution center, The latest version number is 2.3.002.
Once you have done this re-run the hardware scan, Hopefully this will solve your problem.
And welcome to the forum.

IPAD 1 problems after ios 5.1.1 update, itunes does not recognize IPAD.. I check the device manager, it identifies an unknown device (My ipad) but unable to use it.

I am using the generation 1 IPAD.
I recently updated my ios from ios 4 to ios 5.1.1, I did the restore after the update and all seemed fine as it was detected the first time.
I tried connecting the IPAD again but it shows that the computer, itunes is not able to detect the IPAD.
I checked on the device manager, it identifies an unknown device (IPAD) and says no software for the driver. I am using windows 7 on my laptop. I never had any such problem with the iso 4. Any suggestions as to how this can be solved?
Thanks,
Vinay

Thank you, I tried uninstalling the device driver to reinstall again. After doing the scan for hardware changes, nothing flashes on the device manager. I dont see anything related to the IPAD or any other device for which driver shows unidentified device. It is as though the device is not being seen by the computer at all..
I even tried flashing the home/sleep buttons together but that doesnt seem to identify any device either.
Anything else I am missing?

Unknown devices z60m

Unknown device on other Devices
FN+ Hibernate not working

Solved!
Go to Solution.

Hi sajimathew,
Could you please provide some more info about your computer and OS like what Windows version do you use and is it 32 or 64 bit? What is the model/type of your z60m? You should find a sticker under the computer in the format "xxxx-yyy" where the X is 4 numbers and the Y is numbers and letters (for example 4328-3EG). Do NOT post your serial number in public, i'm only asking for the model number.
Did you clean install Windows using a standard windows installation CD/DVD or did you use a Lenovo recovery CD/DVD set?
For the Fn + function key to work you need to install the hotkey features software. The other unknown devices is probably some missing drivers because you did a clean install.
I would recommend that you download Lenovo system update that will give you a list of drivers and lenovo software for your computer and it will give you the option to download and install all the drivers as well as other Lenovo software. That will save you a lot of time and work compared to downloading and installing each driver manually. You also have the option to deselect a driver or lenovo software if you don't want everything.
http://www-307.ibm.com/pc/support/site.wss/tvsu-update.html
Version 4.0 is for Windows 7 only while 3.14 is for XP and Vista. After using system update and if there still are some missing drivers or features that won't work you could reply to this thead asking for further help. In case of missing drivers it's helpful if you include the hardware ID which you can find by doubleclicking the device in device manager, select the details tab and select hardware IDs from the dropdown box.
