This problem occurs because the Peripheral Component Interconnect (PCI) device driver does not correctly update the device settings to reflect the new configuration.

Hibernation

Hibernation is the S4 power-saving state. Hibernation saves open documents and programs to the hard disk, and then turns off the computer. When you are ready to use the computer again, the computer comes out of hibernation in seconds. Then, the computer restores all the open programs and documents that were saved. Hibernation uses the least amount of power of all the Windows power-saving states.

Unlike sleep, hibernation does not require any power to save open documents and programs on a mobile computer. Because sleep requires a small amount of power to maintain itself, Windows automatically puts the mobile computer into hibernation after some time to help conserve battery power.

Additionally, because hibernation on a mobile computer does not require any power to save open documents and programs, Windows also puts the mobile computer into hibernation automatically when the battery charge reaches a critically low level.

You should use hibernation on a mobile computer when you know that you will not use the mobile computer for some time. Also, use hibernation when you know that you will be unable to charge the battery during that time.

Sleep

Sleep is the S3 power-saving state. Sleep saves all open documents and programs. Sleep also allows for the computer to quickly resume full-power operation. Typically, this process occurs within several seconds. For example, you can put the computer to sleep as quickly as you can pause a DVD player. The computer immediately stops what it is doing and is ready to start again when you want to resume working.

To put a computer to sleep, click Power on the Start menu.

Notes

•	You may be able to press a sleep button or close the lid on a mobile computer to put some computers to sleep.
•	When the computer is asleep, the hardware lights may slowly flash or change color. To learn more, see the documentation that is included with the computer. Alternatively, visit the Web site of the manufacturer.
•	The computer may automatically sleep after a period of inactivity.
