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.

HP Pavilion TS 14: Unknown Device (Windows 8.1)

Just wanted to share my experience after reformatting my brand new HP Pavilion TS 14.
- it came with Windows 8, but do not like all the bloat that comes with OEM installed OSes.
- backed everything up, and reformatted.
Now.. i was able to find most of the drivers on HP's website for the specific model.
- except for 1.
Unknown Device
ACPI\VEN_ASD&DEV_0001
ACPI\ASD0001
*ASD0001
i actually found a post on here and the expert said it was related to Graphics.
- but i installed all of AMD drivers & Software.
- i even updated via Windows Update.
Googling was not fruitful, as this specific model is either too new or not popular.
But eventually did find it.

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.

Lenovo X240 keeps rebooting with Kernel-Power (Event ID:41); Windows 7 Professional

Hi All
I have my newly Lenovo x240 installed with Windows 7. Sometime, it can boot up, but sometimes it keep rebooting during the windows logo appear.
When it goes wrong, it will have the following screen.
But, if I am lucky, after several "auto-reboot", I can get into the Windows 7. But sometimes, it shows the similar screen above (without windows logo but with what my current desktop), and it then auto reboots.
This scenario is so random, I don't know how to fix it. At this stage, I don't want to use system restore, as some software is installed by my client which is not located near my office, while the reboot issue happens before those installation
Here are some event 41 details that I captured.

Hi JackyCheung,
I would strongly you to ensure you have the latest drivers and also Windows Updates installed before proceeding with anything else. Have you ran the diagnostics to see if anything hardware related maybe causing the issue?
In this scenario I highly doubt System Restore would help, was it working OK when you got it? what has changed since it was working without the issue?

Iphone 3G on windows 7 (64bits) shows as unknown device

HP Pavilion tx2500 Notebook PC
ADM Turion X-2 Dual core
Windows 7 - 64Bits
I downloaded the latest version of Itunes and haven’t been able to use since
Every time I connect Iphone to computer, PC recognizes (it shows on Portable devices)
but somewhat shows also in another devices (unknown device) and Itunes doesn't recognize or even shows anything.
I uninstalled and reinstalled Itunes and all apple software (Bonjour, QuickTime etc) about 15 times every way I could imagine.
I extracted files (usbaapl64). I tried to update drivers with no success.
I uninstalled Anti viruses, scanned HD, updated some video/sound drivers
It works on my husband’s computer (another HP)under windows Vista 32bits but it’s not working on mine for the life of me.
I can’t figure it out what its causing the conflict and would appreciate any suggestion
I do not really want to try to jump using the restore since last time I did it I had a hard time to download/update my contacts and settings and ended up having to download MobileMe
Pls help

todays update
It got worse before got better
I uninstalled and reinstalled Itunes a couple more times. I even tried to install a 32bit version since task manager shows Itunes 32*exe.
I finally gave in and restored Iphone to factory settings and then my iphone could only call 911 (emergency calls)
I try to connect again to restore it but it didn't work. I tried the DFU and got a error msg "error-message-0xe8000001"
I researched the error msg and found something about USB2.0. I went to HP site and downloaded an update for some drivers and voila
right now iphone is being synchronized
hopefully I won't have any problems with my contacts like I had last time
this happened to me

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........

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

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!

G555. Need drivers for SM Bus and another Unknown device for Windows XP.

I try to install Windows XP on my G555. I got all other drivers, but cannot find drivers for SM Bus and an Unknown device. And what's this device?
The second problem is that after I installed all the drivers, the card reader disappeared. It was there after I installed Windows XP, before I install drivers.
Thanks a lot.

Hi Simpleguy,
Welcome to the forum!
In thinkpads, it's usually intel chipset driver. For AMD based G555, I wouldn't be surprised if this is the driver you need:- http://consumersupport.lenovo.com/us/en/DriversDownloads/drivers_show_2476.html
As for other unknown device, find it's PCI ID with any other known information and paste here.
Hope it helps.

Satellite A660-10W - After Windows 7 installation some unknown devices

So I have the Satellite A660-10W, and I reinstalled the Windows 7 it came with Windows 7 ultimate 64bit. First thing is when I use fn+F6/F7 (other combinations work) for brightness levels it doesn`t work, brightness doesn`t change. And the other thing is that there seem to be some unknown devices.
Here is everything hope someone can think of what could it be, thanks in advance. :)
Link: [http://store.picbg.net/pubpic/B4/3E/3ca598fbde5fb43e.png]

OK you and my friend are right, because I installed the video card drivers from nvidia`s website, not from toshiba, now brightness works :D
And I reinstalled Windows because one thing there were no partitions only one lonely drive and I wanted 30-40gigs for windows and the rest for stuff, not when I decide do reinstall lets say a year later with work and media on it to lose everything. I didn`t do any back ups, even all the shop assistant talked about when I bought it was to buy some dvd`s and backup, but I said I never did that before so why would I need it now, anyway now everything works perfectly, iI`m prepared for the next time :D , thanks for the help. :)

[Helix gen2] Clean Install of Windows 8.1 - one unknown device left

Unfortunately, there is one unknown device left in the device manager:

ACPI\VFSI6101\1
which I thought could be solved by this driver:

I found a few vague references of VFSI6101 being related to a Validity Fingerprint Sensor.
Looking at the Helix Gen2 driver pages: http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-helix-series-laptops/thinkpad...
and specifically at the FPR software package page:
http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-helix-series-laptops/thinkpad...
there's a reference to: "Synaptics FP Sensors(WBF) VFS6101". Pretty close!
So you might try that to see if it clears up the orphaned device.
Hope this helps a bit.
Regards.
