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........

Where Can I Find Compatible Docking Station for Lenovo G780

Hi representative,
I have a lenovo G780 laptop and I am looking for a docking station that matches the G780. The model name is 2182,
I have searched the lenovo shop but I cannot find any docking station that matches. Could you please help me find which docking station model that works for my G780 and where I can buy that docking station.
Thanks for your help.

As far as I know there is no custom-designed docking station for the G780. Instead, consider a port replicator like Lenovo USB 3.0 Port Replicator. It connects to your G780 using a single USB port so it's almost as convenient as a docking station.

27" iMac as monitor for Lenovo T400 laptop (VGA out)

I thought I read that it would be possible to use the iMac as an external display. I bought a cheap cable that is Mini-DisplayPort (M) to VGA (F), and I also bought a VGA cable (M-M). I plugged the cables into each other, then into the iMac, then into the Lenovo T400 laptop I have to use for work.
The iMac didn't react at first, then, when I pressed cmd-F2, the display on the iMac changed resolutions to something like 640x480, but was still displaying the Mac. I looked at the Display control panel on the Lenovo and it could see that a monitor was plugged in, and could see what size/resolution it was. However, even when I clicked "extend desktop onto this display", it still didn't display anything from the PC onto the iMac screen.
All went back to normal when I unplugged the cables.
Thoughts?
Sure, it could be the cable(s), but I was intrigued that the Windows Display Control Panel could see that there was a monitor there.

Brent D. wrote:
I read that. It says, among other things "using a Mini DisplayPort to Mini DisplayPort cable or using a converter that converts other electrical, video, and audio protocols from another source device to Mini DisplayPort compliant signals. (Cables and converters available separately.)"
A 'simple' VGA to Mini DisplayPort adapter is not sufficient to provide "+Mini DisplayPort compliant signals+" as mentioned in that article.
For that you would need an Analog-To-Digital converter and those are ranging in about USD 200 or more.
Are you saying that the Mini DisplayPort adaptors that go from Mini DisplayPort to VGA, which I bought, only go from Mac to VGA monitor, rather than in both directions?
Yes, that's exactly the point (see above).
Sorry

Lenovo G510 Laptop Windows 7 64 bit - no wired or wireless access.

I recently bought a Lenovo G510 laptop and installed windows 7 64 bit onto it. After the install, I had to install all of the drivers, and everything was working fine.
Today I opened my laptop after having closed it ten minutes earlier, only to find that it wouldn't wake up from sleep mode. After trying everything I could think of, I did a hard restart and chose the 'start windows normally' option. However, when Windows started back up, it no longer recognized any internet sources, wired or wireless.
Windows troubleshooter says I need to 'turn on wireless capability'. I don't see a wireless hardware switch anywhere on the laptop. fn+f5 does nothing. No other keys look like they control internet. The device manager says all of the network devices are working normally. I tried reinstalling the drivers, but that didn't do anything either. The Windows Mobility Center says that the wireless is turned off, but the 'turn wireless on' button is greyed out and is not able to be clicked.
I'm all out of ideas. Anyone have any suggestions?

Hi nej,
thanks for posting and welcome to the community. As you may already know when it comes to wireless issue there are many factors that can cause that different factors to look at. However in your case I would suggest you to click on "Start" and in the search field type "Services.msc". Click on services and once the services window opens, search for "WLAN AutoConfig". Doulble lick on it and check if the service is started or not? If it is not, ensure that it is started.
Hope this helps.

Starting with Windows 8, the conventional Power Manager with charging thresholds is no longer officially offered.
Here's a third party tool to set what you need:

You still need to have the requisite power management drivers installed for it to function properly.

How to create recovery disks for Lenovo H530s with WIndows 8.1

Hello there,
I just purchased a Lenovo Hf30s type 10131 with Windows 8.1, mini tower: http://support.lenovo.com/us/en/products/desktops-and-all-in-ones/lenovo-h-series-desktops/lenovo-h5...
I like to create recovery disks, but the already installed program OneKey Recovery does not have the option of recovery disks, it allows only larger media such as USB stick and hard disks.
Here to I have 2 questions:
1. Is there a way to create a recovery disks that will create the original factory settings with 5 partitions?
2. Does any one knows if the recovery siskd sold by Lenovo (for Netherlands they cost between 23 and 38 Euro) would do the job by creating the factory settings with 5 partitions?
My goal is to reformat the hard disk and aprtitionig it the way I need it, but in case of anything, I would like to be able to go back to the original facttory state of the unit, especially if I have a harddisk failure and neer to replace the hard didks.
Thank you in advance and I wish you a very pleasant and successful day.

Lenovo g780 polish instead of english windows and problems

Hello
One week ago i bought a lenovo g780 laptop. I turned it on and although in the website of the store i bought it (e-shop Greece) says that it comes with windows 8 english , mine was with polish windows....
I contected them and they told me that now with windows 8 you can change the language packs so there is no problem. Really... i knews that but the problem was... how i am supposed install windows 8 when the isntaller was in Polish. Anyway after 2 hours with another laptop next to me translating from google i managed to install it and go to control panel.
I changed the language and i thought my problems was solved but... some things were still in polish. Some others some times were in english and other times randomly in polish. For example when i was right clicking on desktop one time i could see "graphic properties" and the next time it was in polish.
I contacted them again and they told me that it is not their fault and if i want someone to blame that should be lenovo and microsoft. Microsoft for opening language packaged and lenovo for giving them products with whatever version of windows 8. They told me that they have an image of english version of my laptop and they could replace it.
So i went there and came back home after 2 hours. But... an image ... is an image right? It supposed to be the same as the polish version. But it wasn't... The first time i log in windows i get an error message. I can't remember
the exact message but it had something to do with "theater something". That message never shown up again. Only the first time.
After that i tried to disable my touchpad. In the polish version i had an option to disable it when a usb mouse device was plugged in. Now the only way to disable it is to ... "disable it" . Also when i click moodpad or pressure graph i get an error message saying "sorry this program requires a synaptics touchpad and the synaptics pointer device driver. What was giving me the option to disable touchpad only when i had a usb mouse? How i can get it back? Also the lenovo features are not the same with the ones i had in the polish version. Some things are missing. Some other things are not installed but they are in a folder with the installation. (mcafee for example).
I know that those are not real problems and most of the things can be fixed if i start searching but this is not the case right? I bought a laptop with windows 8 ENGLISH version. Not polish not chinese not russian. The shop i bought it blames you and they told me the can't change the product description from their website because the description comes from you. So what's the truth? Should i go back to the store and start screaming this time or things is like they say/

Hi Novikor42,
The order to re-install the driver is already sorted out in our Support Website; please download the drivers or all of them at a time from our website and install directly which will replace the drivers in the computer that are already installed. Below is the link to steps to download the drivers:

Hi can anyone help me ? My lenovo G780 laptop keeps freezing its a Pentium CPU B2.10 GHz with 4.00 gb ram and 64 Bit operating system windows 7, it is only just over a week old so no other programs are installed only windows 7,
When I say freezing I mean the computer freezes and I have to turn it off by holding the on /off button as the keyboard wont work either.

It will freeze almost immediatlly when I turn on the laptop.
Does it occur before Windows begins to load?
If so, software on the hard drive is not responsible.

I just bought a B590, model 20208, with, i3-3110m, 500GB HDD, GeForce 720M.
I installed Win 7 64bits, but in Device Manager, before installing all the drivers appeared Other Devices an Unknown Device with thise details: code 28, Device type: Other devices; Location: on Microsoft ACPI-Compliant Embedded Controllert . After installing drivers, the problem persists
Another problem was with PCI express but resolved with Intel Management Engine Interface drivers.
Other problem resolved was with the GeForce 720 M videocard; wasn't recognized but resolved with the last driver from GeForce site.
So... the last problem remained it's The Unknown Devices.
Could anyone help with this one?

hi nikos78,
Can you check if this is the driver for it.
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/gtku09ww.exe
Check if the Hardware ID of this device is a ACPI\VPC2004
on that same windows that you posted click the Details tab and change the value to Hardware ids
Now check the detail that will show below, if that shows ACPI\VPC20004 then that is a Lenovo Energy Management Controller.

Playbook showing as unknown device in desktop manager

Hi
Just bought a Playbook and wanted to transfer some files across to it. Unfortunately I have come up against a fairly major problem with this. First thing I did was connect it to my PC and start up Desktop Manager, unfortunately the Playbook comes up as 'Unknown Device'. Tried checking all settings including everuything recommended in article KB27464 with no success. The Playbook shows as network device in Device Manager in both the PC's I've tried (one runing Win7 Starter and the other Home Premium) and as far as I can see all settings correct but no joy.
I then tried using the network share option as suggested on the support site. Typed in the relevant IP address (file:/192.168.1.5) in the run dialogue after truning WiFi sharing on with no luck. All I get is Windows can't find the relevant folder! Then tried the same technique but using the USB IP address but still no luck!
Can anyone help me as after many years of enjoying various blackberry devices this tablet is wearing my patience very thin.
Carl

Hi
Thanks for the reply, I was going to return the tablet this morning but thought I'd give it another go. Anyway after turning off both WiFi and Bluetooth as well as disabling sharing I plugged the Playbook in and it was detected! Anyway now managed to get it synched, updated and bridged to my 9900 so everything's looking great.
Thanks again for you advice, hopefully I can help someone else in the future as I get to know more about the tablet

Dv7-3165dx unknown device in device manager

I have a dv7-3165dx. I installed and intel SSD and windows 7 professional 64 bit.
I downloaded the device drivers from the hp web site, but still have 1 unknown device in device manager.
How can I figure out what I need a driver for?

Don't know if you ever got this resolved but the issue I think, assuming that you were having the same problem as mine, is the Webcam. Check the device manager see if an Imaging device appears. If not this SP should resolve the issue. It resolved mine. HP DV7-3165DX Windows 7 64x fresh install.
