JenMarG,

Thank you for using Dell's Community Forum.

As a test, go into the mouse’s >properties>hardware tab>power management tab> and take the check off of “allow this device to bring system out of standby” then reboot.

Hi,

I also had this problem on a D400 (with latetst BIOS > A07) when docked. What i did 1st was un-dock the laptop and only use the touchpad. Update the Notebook System Software, then re-boot. Then i added the latest Logitec mouse drivers. I then connected the USB mouse, tested all worked ok and shutdown. I then re-docked the laptop with the mouse connected to the docking station USB and it has been working fine since. The OS is Windows 2000 SP4.

I have between 15 and 20 new Latitude D505 and all those with or without a docking station are having problems with the USB optical mouse supplied by Dell. It freezes up and the user has to plug it in a different USB port, then the problem happens again. It also freezes up when connected through the USB ports on the keyboard or on the Flat Panel monitor. I tried using a USB to PS/2 converter on the docking station but then it didn't even see the mouse at all (normal PS/2 mouse works fine).

I personally am using a wireless Kensington mouse and haven't had any problems.

I have been having issues with the Mouse that Dell gives you.  In and out of Docking stations.  Myself have been using a Standard Microsoft Wireless Keyboard and Mouse and have no problems to date.
