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.

G500 - Unknown Device in Device Manager

Hello!
I just buyed a Lenovo IdeaPad g500 from here (so you can see the specs):
http://www.pcgarage.ro/notebook-laptop/lenovo/156-ideapad-g500-procesor-intel-pentium-2020m-24ghz-4g...
I installed windows 7 and then i installed all the drviers from the cd. I doublechecked, i did not missed anything. Then I updated some drivers to the new versions (chipset, video, audio).
But still i have a device with missing driver. It says Unknown device. under properties/details i found this:
Hardware Ids - root\LenovoVhid
Physical Device Object name - \Device\0000003a
I have succesfuly installed Energy Management and Thinkpad Management drivers too, but the device is still unknown and missing driver.
ThankYou very much!

Hi Morega,
Uninstall Lenovo Energy Management Power Management and try with this one: http://download.lenovo.com/consumer/mobiles/emw7034.exe If it does not help too, uninstall it and try with the one for Windows 8: http://download.lenovo.com/consumer/mobiles/e80femww.exe The first one I linked could help.

Lenovo X240 Unknown Device Windows 7 64bit

Hi All,
I was wondering if somebody can help me indentify the missing driver from my Lenovo X240. I'm currently running windows 7 64 sp1 Enterprise and I installed all the drivers except for one. I've contacted Lenovo technical support in Atlanta Georgia and they couldn't figure it out. I'm attaching a few screen shots to see if anybody knows what the missing device could be...
Thanks for your help.

Lenovo G500 - Intel Rapid Storage Technology" SATA disk on Controller 0, Port Unknown detected"

Hi Folks,
I have a lenovo G500 laptop which i had purchased during thanksgiving vaction in 2013. The machine was working fine till June 2014 when I stated getting Blue Screen of death with error messages "irql_not_less_or_equal" The OS was windows 8.1. This created lot of problem while booting , the machine would not boot at all.
Along with this message I started getting this message "Intel Rapid Storage Technology" SATA disk on Controller 0, Port Unknown detected". This message was coming very often.
I along with Lenovo support did all the things possible, like factory reset etc. Finally the machine was sent out to depot for repair in July 2014. They replaced the hard drive and sent the machine back.
I got the machine back on 22nd July and since last week ,ie, 14th July I have started to get the issues again. My IE and Firefox will suddenly hangon and the blue screen will appear again with same message "irql_not_less_or_equal" occasionally. Yesterday i started getting Sata disk message again.
I wanted to understand why this message is coming back along with blue screen of death. Is there some problem with Windows OS or hard disk seems to crash again?
Thanks in advance
shailesh

hi Shailesh,
Welcome to the Lenovo Forums.
From this article, this is the IRQL_NOT_LESS_OR_EQUAL possible cause:
"This bug check is issued if paged memory (or invalid memory) is accessed when the IRQL is too high.
The error that generates this bug check usually occurs after the installation of a faulty device driver, system service, or BIOS.
If you encounter bug check 0xA while upgrading to a later version of Windows, this error might be caused by a device driver, a system service, a virus scanner, or a backup tool that is incompatible with the new version."
From your description, It's possible that the HDD or the RAM is faulty but it's also possible that it's a software (driver) issue -- which is the hard drive (SATA) controller.
To verify, I would:
1. Run a diagnostic on the HDD (via Lenovo's Storage Quick Test or via HD Tune)
- http://www.hdtune.com/faq_1.html
2. Run a diagnostic on the RAM (via Memtest86+)
- RAM - Test with Memtest86+
3, Read the BSOD dump file to see what file caused the crash
- How to solve Windows 8 crashes in less than a minute
- If the file is associated with the Intel Rapid Storage Technology Driver (SATA Controller), uninstall the software from the Control Panel > Programs and let Windows install a generic Windows driver.
- Link to picture
If you get an error after running the diagnostic test, I recommend you contact Lenovo and report the issue.
Regards

HOW TO FIX HD AUDIO/UNKNOWN DEVICE/DEVICE WON'T START LENOVO H320 Win 7 64-bit

Fix for - HD Audio devices won't start or you can't load correct driver. Lenovo H320 - Win 7 64-bit I-3 processor. 5 series/3400 chipset
Here is a working procedure to fix the problem when you install windows 7 64-bit and can't get the correct drivers installed for the HD Audio devices 1)Realtek AC97 HD Audio device id = HDAUDIO\FUNC_01&VEN_10EC&DEV_0662&SUBSYS_17AA3604&REV_1001
and 2)Intel HD Audio device id = HDAUDIO\FUNC_01&VEN_8086&DEV_2804&SUBSYS_80860101&REV_1000 Regards >>> Sucromatic
For an IBM LENOVO 320 with Windows 7 64-bit Home Premium Version download these drivers to a directory in a second partition to prevent this nightmare from happenning in the future.
1)AC 97 high def audio version
Realtek HDA 2.67found on http://wikidrivers.com/wiki/Main_Page or at www.realtek.comon right of screen on homepage and
2) Intel HD GRAPHIC and HD Audio version
Intel GMA 15.22.52.2559 (Vista/7) 14.46.8.5387 (XP)
found on
http://wikidrivers.com/wiki/Main_Page.
Select your OS and and whether 32 or 64 bit. I recommend the .exe version as it works very smoothly. Uninstall HD AUDIO DEVICE or whatever it is called maybe "unknown device" with ac97 device ID "HDAUDIO\FUNC_01&VEN_10EC&DEV_0662&SUBSYS_17AA3604&REV_1001." Afterwards install AC 97 HD Audio Driver.
After install reboot and wait till computer completely starts.
Now uninstall Intel HD Graphics or your graphics device. When you get the uninstall box open, select delete the driver software for this device and then OK. When prompted to reboot select NO and Immediately start the install of the Intel GMA driver. Which installs both the Graphics Adapter and the Intel HD Audio. Reboot when finished and all HD Audio devices will be functional (hopefully). You will now have these versions installed. As shown in device manager/device properties/Driver tab
Now uninstall Realtek AC97 driver you first installed to delete annoying Red Lexmark/realtek icon in Notification area (If your computer shows it after reboot) and windows driver update will install a microsoft driver (shown below)that works without the stupid lexmark red icon. See below. You will now have these versions installed. As shown in device manager/device properties/Driver tab
High Definition Audio Device
Driver Provider: Microsoft
Driver Date: 11/19/2010
Driver Version: 6.1.7601.17514
Digital Signer: Microsoft Windows
IntelR) HD Graphics
Driver Provider: Intel Corporation
Driver Date: 1/10/2012
Driver Version: 8.15.10.2622

Intel (R) Display Audio
Driver Provider: Intel(R) Corporation
Driver Date: 8/23/2011
Driver Version: 6.14.0.3086
Digital Signer: Microsoft Windows Hardware Compatibility Publisher
Voila. Now go to intel and run a driver update scan and it will likely correctly identify your Intel pieces and offer downloads for any that are not current. Good Luck!

it is a user to user forum without any intervention from apple information-wise.I think this question appears and being discussed in another thread

G580 Lenovo Support Center - Device Manager - Unknown device

Hi Team,
Recently I have Updated my Laptop from Windows 8 to Windows 8.1 single language pack.
Once Installation is completed, I faced problem in starting Dolby Audio driver, I have installed the latest driver and it got resolved.
Next came the problem in Bluetooth device in accepting files from my mobile, then done the same. Installed latest driver and it too got resolved. But still i am facing the message "Unknown device" in Lenovo Support Center in Device Manager.
I have checked in Device Manager. But no device is indicated in yellow color.
Please let me know, how to identify which device is causing this problem and how to rectify this.
My Laptop details:
Model : G580
Product ID : 20150
Let me know if you want more details.
Thanks,
Sathish Kumar

Hi Yigit,
As I have already mentioned, I didn't find any device which is indicated as Unknown in Device Management.
I have shared the Images for your better understanding. It is only displayed in Lenovo Support Center alone.

Unknown device in Lenovo Solution Center Helix

It's not causing any problems, but it's killing me to know there is an unknown device that I can figure out what it is!!! Talk about Fly in the Ointment.
Why is it there? Why doesn't windows not know what it is? What's it's motivation?
No external devices plugged in, wireless printer driver installed and working correctly.
This is one for Sherlock, or THE LENOVO COMMUNITY
I looked in device manager, nothing is popping out saying "Hey I'm unknown"
Lenovo Solution Center sees it but doesn't have a fix for it, and it gives me that smug number 1 with a red circle around it under check up (the nerve!). Taunting me that something is not right and there's nothing I can do about it.
Help me Obi Wan Kanobi, your my only hope!
Solved!
Go to Solution.

Lenovo Solution Center currently has a bug that happens on systems with touchscreens, it shows an unknown device like you say, even though there isn't anything wrong.
There is supposedly an update to LSC coming this week or next, it should fix this bug.
And there is something you can do about it, click on the "remind me" option and then select "never", then LSC won't bug you about this non-issue anymore. Sorry for this inconvenience caused by LSC.

'Unknown device' in Lenovo Solution Center, but not in Device Manager

Even with all the latest updates installed, I still get this annoying warning from Lenovo Solution Center
'Unknown device' - status 'not installed'
Control Panel / Device Manager gives no signals something is wrong.
why?!
Details:
Computer: Thinkpad Yoga (TPY)
OS: Windows 8.1 all updated
Lenovo Solution Center version: 2.2002 / revision 17630
External device attached to TPY: OneLink Pro (also has latest driver = Realtek 8.10.1009.2013)
Thanks in advance

It seems to me you are missing some update from Lenovo. I had the same issue, however just recently after updating any available software/drivers for the TPY the message has disappeared.
Glad to hear the problem is solvable. Regarding missing updates, I honestly would not know which one.
Lenovo's own update programs ('L-Update and Drivers' & 'L-System Health and Diagnostics') inform me that all drivers are up to date.

Unknown Device in Device Manager for Lenovo G780 laptop, Windows 7

Hails all. I am trying to figure out what the Unknown Device is under Other Devices in my Device Manager. I recently got rid of Windows 8 and put Windows 7 64-bit on my Lenovo G780 laptop. I installed almost everything from the Lenovo site --- all of the drivers and such, software, etc. I cannot figure out what this device may be. The only external device connected to the laptop is a Kensington usb mouse. Any ideas?
I did run the PCI test program and the Motherboard test program that Lenovo provides and it didn't find any errors. Windows Update hasn't found update/driver/software for the Unknown Device. The Lenovo Solutions software only tells me to open Device Manager.

Welcome to the forum!
Since Windows Update didn't pick up any missing drivers, I'm guessing you are missing a driver for a device that would be propriatary to Lenovo. During the installation of Windows 7, did you install the One Key Recovery software ? If not, the One Key Recovery button maybe triggering that exclamation mark in Device Manager since there is no driver to tell Windows what to do with that button.
If that wasn't the problem you can try running Unknown Device Indentifier to see if that utility can indentify the unknown device. The free program can be found at the link below........

WIN XP Pro on Lenovo G500 - Drivers - Energy Management

I bought a new G500 and asked the vendor to install WIN XP SP3 PRO - 32 bit from my existing disc.
The vendor installed it, but it is not working perfectly.
The Device Manager shows a few items - such as:
(01.) ACPI/VPC2004 and
(02.) Network Controller (Device ID being PCI\VEN_168C&DEV_0032&SUBSYS_32187AA)
(03.) Bluetooth USB Host Controller
as unknown items.
Regarding the (01.) ACPI/VPC2004 the following Lenovo Support page
http://support.lenovo.com/en_US/diagnose-and-fix/detail.page?DocID=HT071645
says to download and install Energy Management with proper Operating System. The said page also contains a link, but that link leads to another page:
http://support.lenovo.com/en_US/downloads/detail.page?LegacyDocID=DRVR-MATRIX
Here, on the new page, I just can not figure out where to go or what to do.
Can anybody please guide this oldman how to install WIN XP SP 3 Pro - 32 bit on my new G500? What are the drivers required for installationof WIN XP SP 3 Pro - 32 bit and where from to download them (if possible with links to download pages), and a guide about the sequence for driver installation, i.e. which driver to install first (after installation of WIN XP) and which one at the last of the process, so that I can install the same.
Thanks in advance

Just to add to the knowledge base: I've been installing Windows XP SP3, 32-bit edition on a Lenovo G500; my findings so far follow. I haven't tested 64-bit. To determine of your system is 32-bit or 64-bit, see: http://www.intel.com/support/wireless/wlan/sb/CS-032028.htm

Device manager now lists the device as:

WIN XP On Lenovo G500 - Intel Core i3-3110M CPU @ 2.40GHz

Because, I must have WIN XP to run some particular applications, I have installed WIN XP SP3 - 32 bit - on my new Lenovo G500 Machine.
Guidance about the necessary drivers for running WIN XP - SP3 - 32 bit is required, as because I am a novice on that count. The Lenovo Download pages do not offer any drivers for WIN XP.
However, the WIN 7 - 32 bit drivers work fine with WIN XP, except the followings:
1.         Chipset Driver Install
                Tried   >> imei110w7.exe
                Result >> Creates Error

                   Tried >>    irst110w7.exe
                Result >>        Got the following Error:
            The Procedure entry point RegDeleteKeyExW could not be located in the dynamic link library ADVAPI32.dll
3.         Intel Wireless LAN WIFI Driver Install
      Tried   >>        wlan110w7.exe
                Result >>        THE DRIVER IS NOT MATCHING - The system detects the availability of Wireless, but, when I go to Connect, the Blue Screen flashes and the system crashes and then restarts, and continues to crash and restart until the WiFi device is turned off. It even does not allow disconnecting the Wireless Network from the system. I have to disconnect the Wireless Network from the WiFi device / Modem.
4.         Intel Bluetooth Driver Install
          Tried   >>        bt110w7.exe
            Result >>        Message >> Warning: No Approprite Driver to be installed"
5    Energy Management Install   >> (32-bit)
Tried >>    emw7034.exe
   Result >>    ERROR: Messages (02 Nos):

                                02.       The Procedure entry point SetDisplayConfig could not be located in the dynamic link library USER32.dll
Can anybody out there help me solve these problems. Where is the mistake that I am committing. Any suitable or compatible drivers are urgently required.
Thanks in advance.

One more thing that I forgot to mention is:
The Device Manager shows the followings with a yellow exclamation mark:
01. Blutooth USB Host Controller;
02. Network Controller;
03. Unknown Device - this I had read that will be recognized after installation of Energy Management;
And, under System Devices (in the Device Manager) PCI Simple Communication Controller - is also shown with a yellow Exclamation.
