Windows 7 - PS/2 Mouse not working !

Asked By barrowhil on 15-Jan-09 08:07 AM
After installing January Patch Tuesday Updates, my PS/2 mouse no longer works
????  I know it is not a hardware fault with either the PC mobo or mouse
itself as I exchanged (caddied) HDD with month old image.  PS/2 mouse works -
I always do mirror image shortly after monthly updates.

I've reverted back to "working" HDD and PS/2 doesn't work.  Use "Image" HDD
(without January updates) and mouse works !?!

Resolution please.

Sorry for ignorance but what do you mean 23 posts form 1/14.  There are lots
of post dated 14th Jan but don't see relevance to PS/2 mouse.  What am I
missiing from your reply.???

I suggest reading these conversations for some work-arounds:

I have no idea on exactly how this occurred - but Microsoft *is* aware of

(** Even if you don't have a laptop **)

If that is not it...
Could be a burned out PS/2 port.  Doesn't matter how old something is - it
can still die.

Betting the above is it though...

Come back - let everyone know... Dell?  Windows XP or Vista?  Service pack

Thanks for this link, the contents of which, when applied, resolved problem
- Offending update was the 'IdeaCom HID TouchScreen (PS/2)' .  How this came
to be included as a required update only Microsoft knows.  All fixed now.

Thanks to all who responded; much appreciated.

From joe 110: first of all, if your PS/2 mouse is not responding - plug in a
USB mouse and click -  Start -  Control Panel - (classic view ) - Device
Manager - Human Interface Devices - double click on IdeaCom HID Touch Screen
(PS/2) - click the DRIVER tab - click the Uninstall Driver button - click ok
until you are told to click Restart. You may have to restart twice as I had
to in Vista Premium but your PS/2 mouse will start working again!
