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
Solved!
Go to Solution.

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

GE60 0NC-006US Webcam not working after Win8 upgrade or BIOS update

So, I upgraded my GE60 to Windows 8 a couple of weeks back and decided to install Skype this past weekend. Upon opening Skype, I was told that no webcam could be found. I checked Device Manager and sure enough, no instance of a webcam or driverless device was detected. Now, I did apply the newest BIOS just before upgrading so I assume that could have broken it as well. I followed the BIOS directions given by the instructions provided on the driver page and everything else works. Furthermore, Live Update says I have the most current version. I am wondering what to do next. Should I reapply the BIOS or how can I find out if the laptop even detects the webcam? I mean, not being in Device Manager and even the Devices window, reverting back to 7 probably wouldn't help since Device Manager shows no instance, correct?

Gnome Power Manager after Last Upgrade

Hi There,
I just did a pacman -Syu and upgraded lots of packages which also include dbus etc.. I just restarted and puzzled that GNOME Power Manager is a lot different now then it's used to be before the upgrade. First of all, it's systray logo is different. Then it's menu, it's options, everything about it are different. I can't see an upgrade in the pacman.log for gnome-power-manager but it's completely changed..
When I pull the AC power and work on the batteries, it doesn't change the status of the applet. So the applet is very useless right now.. Although it doesn't seem to be an applet while it can't be moved around or I can't change anything about it..
Before the upgrade, I was able to get information by simply right clicking on it selection Information.. But now, even that option is completely changed.. Is there something wrong ?

Hello.
Is the bug fixed already? I have some problems with gnome-power-manager, dbus and hal. After installing Gnome everything was just fine, after I reboot I cannot start HAL:
[root@ichi ~]# /etc/rc.d/hal start
:: Starting Hardware Abstraction Layer [FAIL]
[root@ichi ~]# lshal
error: dbus_bus_get: org.freedesktop.DBus.Error.FileNotFound: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory
gnome-power-manager gives msgbox with error about connecting to DBUS.
What is the issue?

Xauth unknown command, WINE crashing X after recent upgrade

I realize this isn't much information to go on. What I'm looking for is some advice on how to proceed debugging this. Where should I look next?
When I run startx, I get
xauth: (stdin):2: unknown command "ef33d0225485e7060dffee1ecb847468"
It seems to load normally afterwards. Everything seems to be fine, until I run a game in WINE. At that point, the mouse cursor disappears entirely (both in and out of the WINE window) and X eventually freezes. This does not happen every time, which makes this whole thing very frustrating.
I'm using a NVIDIA card with proprietary drivers (updated with pacman). Everything is up to date, the nvidia module is loaded in the kernel, and nouveau isn't installed.
WINE does not output anything useful even with a 2>&1 |tee log. The Xorg.0.log doesn't show any errors, save this:
(II) NVIDIA(0): ACPI: failed to connect to the ACPI event daemon; the daemon
(II) NVIDIA(0): may not be running or the "AcpidSocketPath" X
(II) NVIDIA(0): configuration option may not be set correctly. When the
(II) NVIDIA(0): ACPI event daemon is available, the NVIDIA X driver will
(II) NVIDIA(0): try to use it to receive ACPI event notifications. For
(II) NVIDIA(0): details, please see the "ConnectToAcpid" and
(II) NVIDIA(0): "AcpidSocketPath" X configuration options in Appendix B: X
(II) NVIDIA(0): Config Options in the README.

I take the second part back. The issue with X crashing with WINE still occurs intermittently.
I'm noticing that .Xauthority is being given 2-3 entries shortly after login, often the same one twice. Is this normal?
Also, I went through errors.log and found some seemingly relevant lines. This one is throughout (along with a similar one with 16 instead of 56):
kernel: [ 626.673586] NVRM: Xid (0000:01:00): 56, CMDre 00000000 00000000 00000000 00000001 00000001
This is everywhere as well:
/usr/sbin/crond[875]: (CRON) INFO (Syslog will be used instead of sendmail.): No such file or directory
And then there is this:

I know that the first error is related to nvidia, though I've been having trouble figuring out exactly what it means. The second error seems irrelevant but I could be wrong. The third concerns me, whether or not it's related to my problem with X.

Issues connecting to License Server after ServerTools upgrade 8.8

Hi
To run a preUpgrade Check I needed to upgrade the ServerTools from 2007 to 8.8.
Since this upgrade I can not connect to the License Server anymore.
Does somebody have an idea what could be wrong? I removed and reinstalled it twice and I do have a new license file.
The upgrader also shows me the COMMON grayed out and I con not run the Check either. I assume this is for the same reason.
Thanks
Franz

Hi Franz,
After upgrading the server tools with the Upgrade Wizard, the License Server is not started automatically. This issue is documented in a SAP Note [1488839|https://websmp130.sap-ag.de/sap(bD1odSZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=1488839]. In order to resolve this issue please start License Manager after the upgrade.
The 2nd issue (The upgrader also shows me the COMMON grayed out) is described in SAP Note [1433019|https://websmp130.sap-ag.de/sap(bD1odSZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=1433019].
In order to resolve this issue please upgrade your environment either to 8.8 PL10 or to 8.8 PL12.
hope it helps,

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
Solved!
Go to Solution.

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
Regards
Carl

Windows 7 doesn't recognize my iPod Touch 4th generation after I upgraded the device to iOS 5.

Has anyone had any success with syncing a 4th generation iPod Touch in Windows 7 64-bit after upgrading the iPod Touch to iOS 5? Up until I upgraded the device's OS I couldn't for the life of me stop iTunes from popping up and trying to sync anytime I simply wanted to charge the iPod, but now after the upgrade I keep getting a system message that the device isn't recognized. Any ideas...?

HT1349 ITunes failed to start after an upgrade, won't allow me to re-install saying "Apple Mobile Device failed to start, check for sufficient priveleges"

My ITunes library failed to start after an upgrade, now I'm unable to open or re-install. Receive an error message stating that "apple mobile device failed to start, check to see that you have sufficient priveleges to run system". Any help with this? I've tried un-installing and downloading only to get the same message again.

Thank you to "turingtest2", solution for someone else worked for me as well!

I install latest update from my ipad 2, after the upgrade tablet running slowly. Probably the system requirements too high for my device. I think that users with older models should be able to install IOS 6.x.x on their devices or consider buying devices

I install latest update from my ipad 2, after the upgrade tablet running slowly. Probably the system requirements too high for my device. I think that users with older models should be able to install IOS 6.x.x on their devices or consider buying devices from other manufacturers ...
People are dissatisfied with the new update a lot, including some of my friends and acquaintances. Is it reasonable to wait until Apple implements the possibility to return to Ios Ios 6 to 7? And how soon it can be done?
Sorry for my english, i am from Russia.

I have a similar issue. I recently purchased an iPad Mini, and I started off by backing it up from the apps I had on my iPhone. Now, I have a number of apps that never downloaded and that I don't want on the iPad. Some of these are apps that I don't need, while others are the iPhone versions of apps. There are something like 23 apps that I have no use for, but iTunes tries to install every time I connect. I've also tried clicking the 'Will Install' buttons. There's no way to delete these apps from the iPad without first installing them, as far as I can see, and there's no way to NOT install them, in iTunes.
It''s not just annoying, it's causing problems with installation of larger files and movies. Now, every time I sync to the computer, I get a warning that I'm over capacity by 580 MB, and larger apps will not install! Clicking Revert and a bunch of other things doesn't work, either. And I can't just delete some of the apps, because I or my wife use them on our phones!

USB devices won't mount after upgrade to 10.6

Hello,
I recently upgraded to 10.6 and ever since my USB devices (flash drives, and external hard drives) will not mount when the computer is safe mode. The device show up in disk utility but are unmounted. When I press mount it says that the disc needs first aid, I perform the first aid and nothing changes. My computer is always in safe mode, the devices will mount in a normal boot but my computer is not stable in a normal boot. Also, it seems that iPods and cameras work fine.
Thanks for any help!

Well, the problem is that - as outlined in one of the articles I linked to - some USB devices will not work in Safe Mode; that may have to do with the fact the Safe Mode is only meant to be a troubleshooting tool, not a regular way of booting up. Did you have the USB devices attached while upgrading to 10.6? That would also be a problem - I unplug everything except keyboard and mouse.And, did you repair permissions after the upgrade? If not, do it now.
And, the other problem is the fact that you wait 1 - 2 years before addressing the issue; when you had it in for the last repair and it still exhibited the same problems afterwards, you should would have taken it back, possibly with some screenshots, exact notes of how/when/error messages, etc. and insisted on having it fixed or replaced.
So, I'd run the Apple Hardware Test (after you make sure that you have a complete backup) - instructions here:
http://support.apple.com/kb/HT1509
Report back with whatever messages you wind up with.

I cant even get into itunes because it wont recognize it to do a reboot or a rollback.

The terms of service of the Apple Support Communities prevent us from helping anyone with a jailbroken phone.
You're on your own. Good luck.
