W520 Smart Card reader does not show up in Device Manager

W520 Smart Card reader does not show up in Device Manager.
It was working before and now nothing. Nothing happens when SD card plugges in.
Could my smart card reader stop working or is this a configuration issue?
Any thoughts?
thanks

Graphics Card Does Not Show Up In Device Manager (Re: Installing AMD Video Drivers - Windows 8.1 (Step-By-Step Tutorial)

This tutorial is a step-by-step tutorial on how to "fix" issues of a new graphics card not appearing in Windows 8.1 Pro, or not appearing (as a device) in Device Manager, or it's not being detected by Windows 8.1.
This is the "second part" of a Step-by-Step Tutorial on how to install AMD Radeon graphics card drivers in Windows 8.1 Pro.
GRAPHICS CARD IS NOT DETECTED AND DOES NOT SHOW UP IN WINDOWS 8.1 DEVICE MANAGER
This problem can appear if the video card is not installed properly in the PCI slot and as a result the card is not detected in device manager. Check the physical connections again, reinsert the card properly in the PCI slot, check the connections (including the power cables going to the video card, and ensure that the fan on the graphics card is spinning and the card does have power and is properly seated/inserted) and then install the drivers from the manufacturer’s website.
If the video card is in fact installed properly, but the problem of the video card not being discovered/found by the operating system persists, then try these following methods below to check if this solves the problem.
Method 1:
First, I would suggest you to run the following Microsoft Fixit to get the problem automatically detected and fixed. This Microsoft "fixit" App checks if the device is currently disabled or turned off or the driver is not installed.
Hardware devices are not working or are not detected in Windows.
http://support.microsoft.com/mats/hardware_device_problems/en-us
Method 2:
Sometimes, some devices in device manager are hidden due to corrupt or missing drivers.
Follow the steps below to show hidden devices in the device manager and troubleshoot accordingly.
Press the Windows key + X
Select Command Prompt (Admin)
Type set devmgr_show_nonpresent_devices=1 and hit enter
Type Start DEVMGMT.MSC and hit enter.
Once in Device Manager hit the View menu and select show hidden devices.
From here, remove each instance of the AMD or Nvidia card you see as well as each unknown device. Exit Device Manager and reinstall the latest drivers you can find for your graphics card.
After you install the drivers, reboot and see if you get any different results.
If the above solved your problems and the Graphics Card is now working and is now being properly detected/displayed in Windows Device Manager:
If your graphics card is now being detected by Windows 8.1 in Device Manager, but has a "yellow exclamation" mark (or video drivers are not found or not properly installed or the device is disabled) then install the latest graphics card drivers and proceed with this Step-by-Step Tutorial on how to install AMD Radeon graphics card drivers in Windows 8.1 Pro.
Method 3:
If methods suggested above does not help, I would recommend you to contact Apple/AMD/NVIDIA to get the latest chipset, BIOS, graphics card drivers installed properly.

Hi,
Follow the procedure on the link below to create a bootable Ubuntu CD and follow the steps in Part 3 to 'Try it' to see if this OS will run from the CD without the need to install on your HDD. This will show whether the problem is with Windows or a Hardware problem with the optical drive.

URGENT Lenovo g550 webcam does not show up in Device Manager and all drivers cannot be installed

Hello everyone. So my lenovo g550 webcam stopped working after I did a clean install of windows 7 home. When I go under device manager I do not see any unknow devices. When I also go to show hidden devices it is not there. Could anyone give me information about how to fix this and if the cable to the webcam might be broken. If so, is there a way I could convert the webcam's pin outs to usb to test it. I have split an old usb cable into four colored spots. Not sure if i want to test it though. That would be my last resort. If needbe, can you tell me the pin outs for the webcam. It has five connectors. The reason I know this is usb is because my older installation on windows 7 detected it and said that the usb could be faster. Thanks.

Sorry about that. I've only been a member for a few days. I will remove the post with all Capps. Have a nice day!

I got the iphone 5 and it does not show as a device in itunes??

how do i get my iphone 5 to show as a device in itunes?

The iPhone 5 running iOS 6 requires iTunes 10.7. Start iTunes on your computer and use the menu to see About iTunes and determine the version. Is it 10.7? If not you must update iTunes.
Note that iTunes 10.7 requires OSX 10.6.8 or higher on a Mac.
If your iTunes is already at 10.7 then reboot your computer and reset your iPhone. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.

T61p - IEEE 1394 (Firewire) port does not show up in device manager in Windows 7 x64

I have a T61p. On the front, in the left corner, right next to the wireless on/off switch, is a IEEE 1394 (Firewire) port. However, if I plug anything into it, it's not recognized by Windows, and if I go into the device manager in Windows, there is no IEEE 1394 host manager or ports or anything listed there.
I have rebooted and gone into the BIOS, and I don't see anything in there about 1394 either. Is the port there, but the hardwire inside is missing? Do I need to enable it somehow?

Let me clarify that. I have something in the device manager called "SD Host Adapters", and under that "SDA Standard Compliant SD Host Controller". That thing has a Microsoft driver.
However, under "IDE ATA/ATAPI contollers", I do see "Ricoh Memory Stick Contoller", "Ricoh SD/MMC Host Contoller", and "Ricoh xD-Picture Card Contoller".
I also have "PCMCIA adapters" that has "Ricoh R/RL/5C476(II) or Compatible CardBus Contoller".
So, it would seem I have the right drivers for the card reader, I'm just missing anything for the IEEE 1394 contoller...

I downloaded lion and cloud does not show up in my system preferences. Not sure how to get started without finding icloud., I downloaded lion and cloud does not show up in my system preferences. Not sure how to get started without finding icloud.

I just downloaded lion and cloud does not show up in my system preferences. Where is it hiding so I can set up icloud and see what lion is offering that is different from snow leopard.

I purchased Lion on the app program but that did not seem to update my software or my operating system. Curious. It showed up on my menu bar saying it was downloading then disappeared. I can't seem to find it anywhere. Suggestions where I should look to make sure it is installed (which clearly it isn't)
Thanks Roger

Please help! I have photoshop and iphoto does not show it in my preferences edit window. How do I get it as an option in my preferences.

I tried it and nothing changed. Even when I right click on an indiviual image all it does is duplicate it. Iphoto seems to be recognizing my external hard drive as an editor......cannot get photoshop except to drag a picture into photoshop from iphoto, and once I have worked on it and saved it to iphoto I cant find it anywhere.
