Several Unknown Devices after Windows 7 Home Premium Reinstall

After losing all my data trying to encrypt my hard drive I reinstalled windows from my hard drive using HP's settings in the boot menu and got some weird results. One is that my C drive now only only has 65 gb of space, so I created a new partition with the remaining 215 gb on my hard drive. Additionally, my screen resolution has only 2 options, leaving my desktop looking strange. The worst of these problems is that several of my hardware items are showing up as unknown in addition to my wireless internet not working. Would it be better for me to reinstall again or try and find the drivers?
Here are the Unknown devices on my computer listed under other devices with the hardware IDs:

Hi,
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"
Google did not help.
Any help is appreciated.

G530 (4446-22G) unknown devices after Win7 installation

Hi,
I recently installed windows 7 ultimate 64-bit on my father's Lenovo G530 (4446-22G) laptop. In device manager I see 2 "base system devices" in yellow that are not recognized. Does anyone have any idea what those devices might be? I attach screenshot of the device manager both by type and connection.
Also, I installed the Energy Management for win7 64-bit but the Fn keys do not work. Any suggestions about this?
Thank you in advance.

Hi, i believe your Lenovo laptop is abit older model. Pardon me. Try install this and see if it solves your Fn keys not working.

Unknown devices after Vista installation on Satellite Pro U200

I installed vista ultimate yesterday, but unfortunately my U200 is not as vista compatible as the sticker would make me believe.
Non functioning items I've identified so far:
- Speakers and Headphone jack
- Function Keys
- Fingerprint Reader
Almost none of the included toshiba software installs even after turning "Application control security off"
Does anyone know where I can get the new drivers and software or when they will become available?
Otherwise really liking Vista. It is very responsive and simplifies many tasks. It looks nice too, but thats not my priority.
Any help gratefully received
Cheers

This might help others having similar problems. I have been able to get evrything to work except my shortcut keys.

Unknown device after window 8 clean install

Really need help.
I just upgraded my ideapad u310 ultrabook to windows 8, a clean upgrade.
there is one unknow device:
ACPI/VEN_AOA&DEV_2011 (details)
does anyone know what it is...
Plus, does anyone know how to get veriface, onekey recovery back?
Thank you!!

You have to install the lenovo energy management driver
Download from below
http://download.lenovo.com/consumer/mobiles/em8.0.2.3.exe
However, the software for windows 8 may not work because of some issue from lenovo itself. So you can always use the onse for windows 7 if required. Test the windows 8 software first though.

Unknown device in device manager after win8.1 upgrade W540

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: ROOT\SYSTEM\0001
Hardware Ids: root\iwdbus
Device stack: \Driver\PnPManager

This seems to fix the problem.. any idea why?

Boot Camp Unknown devices

In XP's device manager in Boot Camp I get (5) unknown devices after installing the Mac drivers. (1) USB Human Interface Device, (1) PCI Device, (2) Unknown Devices, and (1) USB Device. What are they? Everything appears to be working here. See linked screenshot.

Well, your guess is as good as mine but I'd say we won't get 100% support until Leopard because it's being built into it.

Iphone 5 fallen in water drained for around 20 secs, kept in rice bag for 2 days, worked perfectly for 6 hrs! now it shows to restore, after restoring during activation it says unknown device contact apple care.

hello, i have an iphone 5 it just fell into water and was in there for around 20seconds. I've seen on many of websites saying to keep it in a rice bag for 48 hours nd said it may work so i've done the same. I took out my phone from dat rice bag yesterday which worked perfectly alright for 6 hours and then switched off automatically! when i connected it to itunes it detected as a recovery device which after recovery during activation it shows as an unknown device! been working on it soo long! i live in mauritius here i have no official apple store but my phone is still under warranty. Please help me!!

When your phone was exposed to water, your warranty/support was voided, so you no longer have any warranty. An out of warranty exchange, from Apple, is US $269. Call AppleCare or whoever handles support where you live.

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?

After the update, the screen inscription "unknown device"

after the update, the screen inscription "unknown device"

If movies/TV/Music colums are no there AppleTV is not connected to the internet or at least thinks it isn't.
Being able to access Shared libarries means you have a LAN connection active but not necessarily internet.
I assume Photos are streaming from computer - if you can access Photostream photos however that would suggest internet connectivity.
First things to do are unpower and restart the router and AppleTV and see if menu items come back or now work.

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. :)

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. :)
