Lenovo T400 / T500 :: T420s Windows 8 Unknown Device
Feb 14, 2013
I installed Windows 8 x64 recently and installed all the drivers. I was pretty sure that all the devices were installed.I was having a hardware power management problem before installing Windows 8 that I was hoping was a software issue that reinstalling the OS would fix. Turns out it wasn't software, but had to have the main board replaced under warranty. Even after the main board replacement, I was still pretty sure I saw all the device drivers were installed under device manager.
I'm noticing an "unknown device" listed that doesn't have a driver installed. I know often these can be the TPM or other system device, but I have the TPM installed as well as the chipset software and power management driver. But there is still this unknown device.The only clue I have as to what the device could be is under details, the "hardware ids" property value is "rootsscbfs_storlib_bus3". A Google search brings up nothing for this string. "STORLIB" makes it seem like it has something to do with storage, but I have the Intel RST driver (11.7 from Intel) as well as the card reader driver installed. I can confirm the card reader is functioning fine too.

I have been running ubuntu on my T420s for about 2 years now. Needed a Windows box to work from home so I installed Windows 7 Home Premium - Service Pack 1 on it. Installation went smooth but Windows did not recognize my wireless card, preventing me from connecting to the internet to download and install the rest of my drivers. I tried to manually install the Intel Wireless Lan (bg, abg, abgn) for Windows (64-bit) Centrino Advanced-N 6205 which is what I thought was installed on my machine to no avail.

We installed a Kinston 240 GB SSD in the Ultrabay, and it is not fully recognizing the SSD - it does not show up as a device, though we know the machine knows it is there, and we could use Linux and ghost to it..
We then ghosted to it with no issues. We then put it in the main bay, but it would not boot.
We looked at it from the USB port of another computer, and the files looked fine. Are we missing a driver?

Lenovo T420s is randomly crashing. There is nothing special in the Event Viewer. Only that the PC was not turned off properly. Not exactly BSOD.
Error video on YouTube
Usually happening under some load (eg. game) but I have seen the same running only MS Office. No Macros or special calculations.
I would say this happens due to overheating. This is my second T420s I have same problem with. I work as 2nd. lvl IT so I know other colleagues are experiencing the same.
Frequency decreased once performance settings in power management were switched to balanced mode. Not solved though.

I have a T420s that I bought a couple weeks earlier, it's a used one, so there's no warranty with it, I used it several days without any issue, I don't use it very frequently as I use my corporate one most of the time.
Someday when I wanted to turn it on, it stacks on a black screen and it beeps one beep then two other, nothing showing on the screen not even the thinkpad logo at startup, I thought it was a RAM related issue so I put the one from my corporate PC but without any luck, so I wanted to see if its graphic controller issue, I plug the VGA cable on the laptop and my TV and here I can see the thinkpad startup logo but after that I see a message on the screen telling :
"Real Time Clock Error - Check Date and Time settings. Press Esc to continue or F1 to enter setup" and when I press either one nothing happen at all, still stacks there.

I have a t420s and so far I'm happy with it.Recently I purchased a MC7700 card from ebay with lenovo FRU. Everything looks smooth except that I found there is no way to turn on the mobile broadband switch.i believe I have a whitelist-removed bios otherwise it won't boot. The driver downloaded from lenovo website is installed fine, I can see the card working in device manager. I could read the iccid in windows network settings. Everything looks good, but I just can't turn mobile broadband on.
My laptop runs windows 8.1, I heard there is a thinkvantage connectivity tool that might work for windows 7 but not windows 8. I have quite a few files on my laptop and going back to windows 7 is the last option I would like to try.

I need to do a recovery on a T420s. I want to recover to same state as out of the box. I already backed up all the data. I am using the disc provided by Lenovo but cannot seem get the disc to start the process. I think I set the DVD as the first boot device but it goes right past it and into the normal start up process.
Is there a way to start the process besides from boot up?

My 5 months old SSD crashed and I replaced it with a Macrium created mirror. Everything seems to work except the computer no longer recognizes USB drives. The USB drives are good (checked on other devices), I've removed and reinstalled all USB hubs and drivers - the chip drivers and bios are up to date and the USBs are enabled in the BIOS AND I've done several virus scans (online and local) in safe mode (Malwarebytes, Spybot, ESET, Defender, AVG, Housecall). The USBs are recognized on boot but once Win7 boots the USB for storage devices no longer work.... however, the USB recognize keyboards and the mouse. Guessing a new OS install will fix it, however, I would rather not reinstall everything.

I bought a Roline DP to HDMI cable hoping to be able to watch HD content in my livingroom and not having to plug an extra audio cable as DP should carry sound too.
When I do the same as on the youtube video, I get the following settings in the control panels: [URL] ....
But there's no sound coming out of the TV. I've tried it on my SyncMaster PC/TV Screen and on my Samsung TV in the living room. On the TV in the living room, the windows audio manager shows the device, but it cannot be selected as show above. It stays grey.
I've got a T420s with discrete nVidia Optimus graphics (Quadro NVS4200M). Driver version is 1.2.19.0 for nVidia HD-Audio and 8.17.12.6696 for NVS 4200M. This information comes from the device manager. I installed my system from scratch and used ThinkVantage System Update 4.
Where the problem comes from? I could only imagine that the cable isn't capable of carrying audio, but that seems rather illogic, does it?

I have a Lenovo t420s with dualboot win7 and Ubuntu. I never had any problems until now and could switch on/off my wireless and bluetooth connections via the Hardware Switch (right bottom left of the notebook) or via FN + F5.
However, without any specific reason the wireless and bluetooth was switched off and the the system tells me that I have to switch on WIFI via the Wireless Radio Switch. However, although I can move it, it doesn't make any difference for the Switch.
I tried to reset the BIOS to Default and changed the network settings, and also rebooted several times. I won't work with any of the two systems.

After reinstalling W7 the lenovo solution center was complaining saying that the System Device Driver is not working. I saw that the SD card reader was not working neither so I assumend the missing driver was that one.
From the Lenovo page I dowloaded the driver for the Multi Card port for W7 and T420. After installing it the message dissapeared and the SD cards were recognized properly.
However, after rebooting the system, after a while, the mesage appeared again and the card reader stopped working.
I did install it again and the same happened. It was working and after two reboots stopped working.

W530
Product: 244752U
BIOS: G5ET95WW (2.55 )
Windows 8.1 - Installed from scratch.
I was able to install and configure all drivers but one. I found a tread that suggested installing Lenovo Setting Dependency Package 2.0.0.13 to fix it on a different lenovo model. I tried it without any success.
The driver id of unknown driver is "{48126E0D-4BDD-4D26-8A24-569C7AB522D6}SettingsDriver"

I'm using Windows 8.1 on a t431s. I'm having this problem where none of my external storage is being recognized. Under "Device Manager" any sort of external storage I plug in ends up under "Other devices". When I click on the device, I get Code 28 "The drivers for this device are not installed." Trying to update the driver brings me nowhere. The devices don't appear under disk management.
What's weird is that other USB peripherals such as mice and USB headphones don't have any problem.
Here's what I've tried so far:
Updated the BIOS.
Used Lenovo's SCCM package for Windows 8.1
Tried installing the individual drivers for each hard drive.
Nothing works!

I'm using the W540 with an ultradock and external monitors. After upgrading my W540 to win8.1 64 bit, device manager is showing an unknown device. I'm not quite sure what it is, but almost everything seems to be working fine and Lenovo solution center isn't finding any driver updates.
I did notice that the solution center hardware scan did not test the video card memory and listed that test as N/A. Video and monitors seem to be working fine though and both nvidia and intel graphics show up in device manager.
Device manager lists the device in question as follows:
Device instance path: ROOTSYSTEM001
Hardware Ids: rootiwdbus
Device stack: DriverPnPManager

I have just installed Windows 8.1 x64 on my Lenovo E330.
I downloaded drivers from the website, and installed all of them. But after that there's one device listed as Unknown in device manager, and I can't figure our which device it is.
Hardware ID is {48126E0D-4BDD-4D26-8A24-569C7AB522D6}SettingsDriver, so that doesn't identify the device.
Info from Solution Centre: Product: 3354AF7

I have tried to make a fresh Windows 7 installation, but after installing updates via Lenovo System Update the system gets corrupt.I replaced the hard drive on an T400 and loaded a image that I had on to the drive. After a installing a few updates and program I noticed strange system beaver. So I did a system file check and it came back that files was corrupt and cold not be repaired.So I did a new fresh Windows install. But it to became corrupt after just running Windows Update and Lenovo System Update.So I ran some hard drive and memory diagnostic without find and problems.
Then I did a new Windows 7 install again. After I installed all recommended updates from Windows Update I did a system file check, all OK. The I installed Lenovo System Update and all its recommended updates and did a new system file check, Windows system files corrupt. What Lenovo update is destroying the system?

Ever since i've wiped the machine, i've been having these two problems. When I close the lid, it used to go to sleep straight away, but now I can see the sleep light (and the power button) flash and flash, then it goes to sleep.
When waking up it goes through the lenovo startup screen and resuming windows, then it asks for a password, before I used to open the lid and it would ask me for the password straight away. I know it was going to sleep because I could hear the beep straight away when I closed and opened it, but now it just takes too long.
Also, everytime I boot up into windows or resume into windows from a sleep state, I can hear the device noise, like something is being plugged in/out. But there is nothing being plugged in or out at the time. I can't get to device manager quick enough to see what it is that is causing it. But all drivers seem okay.
Also noticed, when the lid is closed, randomly the laptop turns off (hear the beep) an then turns back off again.
T420 model number: 4180-PR1 with OS: Windows 7 Pro 64 bit

I updated LENOVO V570 to win8.1, every thing looks good except the unknown device question mark in device manager.
It looks come from the power manager driver, because in the message center, it is said, power management does not work with a compatabale problem.

Lenovo T400 to install Windows XP on it..It previously worked fine with windows 7 and 8.1.so it boots in windows XP preinstall screen, it formats hdd and like usual installation automatically restarts after that BUT its black screen, lights and sounds show that it works and goes to next screen BUT the screen is still black. Powering down and turn on again is not showing any screen picture. Opened it removed Bios battery, turned up after few on and off it starts it reset bios.
So now there is picture and it goes on the next screen of windows instalation like normal, after installing devices and stuff it automatically restarts like usual BUT it has NO screen again, black screen, lights and sounds again show that its loading windows end instalation screen but no picture on the screen. Reset BIOS again, it starts normaly and this time it shows BSoD with code 0x7B, after BSOD Black screen again..Maybe its a BIOS setting?!? tried installing with drivers for AHCI and tried installing without drivers for Compatible , what else can it be? Updated the bios to latest version, same result. To say it again - it works fine with other windows, but XP must be installed

I am using T440. I just upgrade the operating system from windows 7 to windows 8 using recovery disk. I upgrade according to the manual paper in the box.
The issue is, the windows 8 is installed in my HDD with capacity 500GB and the SSD 16GB are not detected. My question is, it should be installed in my 500GB HDD or the SSD drive? What are the correct steps to do recovery if I 500GB HDD and SSD drive?

I cannot install Windows 8.1. I have a T430. I go into the app store, start installing 8.1, it downloads, starts installing, and fails just after that point -- at 54% -- with the error message 0x80070002. That apparently means "File not found", but the Windows Update logs don't point to which file is not found, only giving:
WARNING: CSerializationHelper:: InitSerialize failed : 0x80070002
Going into Event Viewer gives the equally cryptic "English ESD Bundle Parent" as a possible cause for the failure.
SFC and chkdsk do not report anything out of the ordinary.
