T420 USB Ports do not work after installing XP

Hello my office has been using Lenovo's for some time now but we recently purchased a T420 and installed Windows XP SP3 on it. The issue we are having is that the uSB ports do not work. I have tried every driver I can find but still no luck, can anyone help?

hey chris0277,
could you check in Device Manager and see if there is any ? or ! symbol on the USB area.
If there is, i do recommend uninstalling the drivers from it and then visit http://support.lenovo.com and update your unit

Some USB ports no longer working after installing Mountain Lion?

Some of my USB ports are no longer working after installing Mountain Lion onto my 21' 2011 iMac. I used to plug in my iphone 4S and charge it, or transfer files onto my iPad but none of the ports no longer work to do this. Funnily enough, other equipment plugged into the works. I have tried changing the cable. Any ideas?

In my experience, the USB ports on the back of an Apple monitor can be re-enabled simply by unplugging and plugging back in the device in question. You might also check to see that the USB Monitor hub shows up in System Profiler. My Apple monitor USB ports experienced no changes in moving to 10.4.7.

USB ports don't work after resuming from standby with Windows 8 on X230 tablet

I have just done a clean install of Windows 8 on my X230 tablet. Before installing Windows 8 I installed the most recent BIOS for this machine (version 2.50). After installing Windows 8 I installed System Update from the Lenovo Website and downloaded all the recommended drivers and other files. I've also installed all the latest Windows 8 updates.
Here are the symptoms of my problem: After resuming from standby/sleep mode, my USB ports do not work. My computer has two USB 3.0 ports and one USB 2.0 ports. All exhibit the same behavior. After resuming from standby mode I have tried inserting both my mouse and a USB thumbdrive, but neither are recognized. After restarting Windows, the USB ports work again... until I resume from standby mode again.
I hope there is a solution to this issue. It is very frustrating.

Thanks for the suggestion about tweaking the "Allow this computer to turn off this device" feature. I un-checked that box for every entry I could find under "Universal Serial Bus Controllers" in the Devide Manager. Unfortunately, the same symptoms of my problem persisted.
I went back and looked at the README file associated with the BIOS 2.50 download on Lenvo's support site. At the bottom of the file it gives a "Summary of Changes". Under version 2.03 of the BIOS (the version just before version 2.50), it says:
- (Fix) Fixed an issue where USB device might not detected when system resume from sleep mode.
This indicates that Lenovo support was already aware of such issues. The problem was intended to be fixed in version 2.03 of the BIOS. However, the issue persists on my machine, even with the latest BIOS.
Hopefully someone from Lenovo can comment here.

USB ports does not work

Hi I have problems with not working USB ports. It used to work. I downloaded actual drivers at msi.com for my gaming notebook GX 60 Destroyer and now my USB ports does not work. What should I do?

What driver have you updated?
Try to do an EC firmware reset by removing the battery and the AC adapter then put the battery back with AC adapter attached.
Same questions like Pegasus asked, does all ports not working? which one exactly? What OS are you using?
Have you done any changes to the system? (for example: self-install OS or changing OS)

Audio output and left USB port is not working!

Hi! I have MacBook Air 13" late 2010, Audio output and left USB port is not working!
What happened?
Part No.: Z0JH000TE RS

If the left USB port doesnt work with an external mouse its seems to be a hardware malfunction of this USB port.
The newest BIOS is already installed?
Have you removed all USB ports from device manager and restarted your notebook?
If you have already tried this, contact an authorized service provider. The guys can try to fix this issue and it should be covered by warranty, if you still have warranty on this notebook. :)

My sound system does not work AFTER installing pc to tv wireless connection

my sound system does not work after installing hp pc to tv wireles device when I am using lap top for other purposes.

Hi,
You don’t install VS2010 on the client PC, then where did the Form Invoice not work? When you run it from another version of VS? Or when you run the application with application.exe?
Based on your description, one form works well, another form does not. I assume that two forms are in two different projects, then please check the .Net Framework used by the two projects. If they are different, you can use the
one used by the Form contact for Form Invoice.
Because this issue is a project issue, I recommend you to consult it on some application forum such as Windows Forms General forum for better support.
VS General Question forum mainly discusses
the usage of Visual Studio IDE such as
WPF & SL designer, Visual Studio Guidance Automation Toolkit, Developer Documentation and Help
System and Visual Studio Editor.

Sometimes you have to reset the SMC two or three times for it to work, don't know why. I've seen that error message before and 100% of the time it was fixed with an SMC reset. I suppose it's possible that your keyboard or mouse IS drawing too much power, do you have access to another you could try?
