Logitech wireless keyboard and mouse. after upgrading to SP 2 the keyboard doesn't work

I have a Logitech wireless keyboard and mouse but after upgrading to SP 2 the keyboard doesn't work.  I also have two friends with the same problem. One of them has the same problem with a Microsoft keyboard and mouse.

System works OK with a wired keyboard

Have you tried changing the BIOS setting to enable legacy USB devices?  I am assuming your wireless receiver is a USB device.
I realize the problem started when you upgraded to SP2 but verify your batteries in all devices.  If you haven't already, upgrade to the most recent Logitech drivers and Set Point or ITouch software.  If your devices are old enough to still be using Mouseware, upgrade the Mouseware then install ITouch as described for your model.

Resynchronize the keyboard and mouse using the connect buttons found on the bottom of the keyboard, mouse and base.
Use the appropriate instructions for your model.  Some are found here- http://www.logitech.com/index.cfm?CONTENTID2=0&CRID=1792&CONTENTID=4549&PAGE=support/products/document&SHOWALLDOCUMENTS=0&AD=PE_FAQ&countryid=19&languageid=1

If the updates and resynch do not fix you let us know which model mouse/keyboard combo you have please.
easy problem...
you know why?

it's because on your P/S keyboard, your num lock is on. or scroll lock.
please make sure that all you plug the P/S 2 keyboard back to the laptop, unlock all button, plug the keyboard out, you are set.


i got headache before as well. but i found it no problem.
the reason why it happens is because your laptop's key structure are not the same with the keybord structure.
so basically, one of the locks will cause the Fn key on the laptop turned on all the time.
you will have problem with keys that have an alternate value if the Fn is pressed together.

so.. hope this really solve your problem. it's been two months hanging here. :p
