Logitech 350 internet keyboard not working

Make your day easier-order a $30 replacement from Staples.

hello, just so you know that the keyboard does not go to sleep, but to answer your question; the problem is within the control panel>power options, check the settings for your system and see what options are there for the computer to go to sleep other than that try a different port on your computer, let me know the outcome.

go to keyboard setting in device manager. check all keys if work properly. u might have your keyboard set to a different format

Logitech webcam usually comes with a CD to install software and drivers. If you are using windows 7 your computer should recognize Logitech Webcam when you connect it to your computer's USB port! Its necessary to have internet connection for your computer and Logitech webcam is just plug and play that means!
Just connect the webcam to your computer and remaining is done automatically!
Also drivers for logitech webcam are available online at their site www.logitech.com
good luck!

If you go to logitech.com you can look up your product and they will give you a list of any software that goes with your keyboard to download.

If you go into the device manager, look to see if the USB controllers and hubs are detected. Or do they have a yellow warning on them.
When USB ports misbehave for me, I go into the device manager and remove them all and let the machine find them again. Then stuff usually works.
You don't say if you have a desktop or laptop. If you have a desktop, are the USB ports in the front of the machine actually attached to the motherboard?
I'm thinking my first suggestion is the one you should try first.
Then make sure the devices you are installing actually work.
Also, for wireless, be sure you push the "connect" button on the device.

It looks like a wireless keyboard and mouse. My Logitech keyboard and mouse have a USB 2.0 receiver, which plugs into any USB 2.0 port. Some have small USB receivers that look like memory sticks. It might be mounted on the bottom of the keyboard or the mouse. My receiver is a small box with a wire that runs to the back of the computer and plugs into the USB port. The receiver has a connect button to send a signal to the mouse and keyboard. Once they are installed you can use the button to make the mouse and keyboard recognized, by the OS.

i have seen some keyboards not work with the usb to serial adapters. try a different keyboard. possibly the oldest one you can find.

Okay, I've had the same problem with their keyboards and mice, first you uninstall and reinstall the driver, if that doesn't help go to start>run then open MSCONFIG. Then find the services and re-enable all of them, along with all the startup entries.
