Question about Logitech Cordless TrackMan Wheel 904346-0403 Trackball
If i move the trackball as the computer is booting up, it finds the mouse ok. But if i walk away while booting, when i come back the mouse don't work. and i haven't had much sucess with the little "connect" button. Does anyone know just when the computer LOOKS for the mouse? Any help would be appriciated, Ken
Well your problem sounds like a unique one, however, I can tell you exactly when you're computer looks at your mouse. When you push the power button the computer goes into the POST mode (Power-On-Self-Test). This is a good minute before you see the Windows login. During POST the processor is detected, how much memory, what hardware is recognized and whether BIOS has Plug n Play. After POST the boot process starts, during the boot process there is a file called NTDETECT.COM, it is used to detect any hardware that is installed and adds that information into the Registry..there are some other files but it does not pertain to your problem. After boot is when you hear the beep on your computer, the one beep is saying all is well and ready for the operating system. So it sounds like your mouse is not being detected either during POST or when NTDETECT.COM runs during POST. Here are some steps you can take: First you must replace the mouse to test its electronics. If the replacement mouse works, the original mouse was defective. If the replacement mouse does not work then the original mouse's electronics are good. In this case the mouse driver or the port hardware is the problem. Find mouse in Device manager, uninstall driver, then reboot see if the Plug and Play picks it up. Update and re-install drivers. If the drivers don't work then its the motherboard, go back to the PS/2 mouse. Hope this helps. Let me know how it goes.
