I have a device that doesn't function properly after waking up from sleep or hibernate; what can I do?
If you can, disconnect and reconnect the device. You can also make sure that you have the most current drivers all of your devices. There are three ways to update a driver:
Use Windows Update. You might need to set Windows Update to automatically download and install recommended updates.
Install software from the device manufacturer. For example, if your device came with a disc, that disc might contain software that installs a driver for the device.
Download and update the driver yourself. Use this method to install a driver that you download from Lenovo's website. Do this if Windows Update can't find a driver for your device and the device didn't come with software that installs a driver. (Check Lenovo's support site www.lenovo.com/support and navigate to downloads and drivers for the appropriate family of systems and select your model)
