Dimension 8300 Cannot Get into Standby Mode

I know there has been some discussion on this issue and I have Googled the subject matter, but have not found a solution yet. When I attempt to go into Standby Mode, I get the message:

The device driver for the "Dell Enhanced Quietkey PS2 with Dell Touch" device is preventing the machine from entering Standby.

I downloaded and installed the latest driver from the Dell Web Site for the Keyboard, but the error is still present.

My system configuration is: Dim 8300 3.0GHz, 1GB Ram, 120GB Serial ATA Harddrive, 3.5 Floppy Window XP Home, SP2 and all current updates Dell 1901FP Digital Flat Panel 128MB DDR ATI Radeon 9800 External USB 80GB harddrive Omega 250 USB Zip Drive Dell Optical Mouse Dell Enhanced Quietkey PS2 Keyboard 48X Max CD-RW 9X DVD+R-RW CD-RW SoundBlaster Live with 5.1 support Epson 1200U Flat Bed Scanner HP Laserjet 3100 Printer (Parallel) HP Officejet d145 Printer (USB)

Anyone with thoughts on how to resolve this problem? I can post more information if needed. Thanks for any insights and-or tips. Charlie ****************************************************** Charliec
