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 !?!

Sorry for ignorance but what do you mean 23 posts form 1/14. There are lots

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!

if you have one a USB mouse:
plug it in.. when loaded.. right click My Computer and click
click on the hardware tab and then Device Manager.
click the + in front of HID compliant devices
find the IdeaCOM HID device and right click.. then click Properties
when open.. click on the Drivers tab and click Update Driver.
choose not to search internet.. click next
choose a specific location click next
choose don't search.. click next
in the list find the Microsoft PS/2 driver.. select it and click Next
the driver will load and it will tell you that you need to restart to
take effect. close all property windows and restart..
when you do, the mouse should be working again
if you do not have a usb mouse:
you will need to do the above with a slightly different start.
press the windows key or (ctrl+esc) to open the start menu
use the arrow keys to move to the control panel, press enter

keys to select System Properties.
once open use the tab key to move the focus to the top row of tabs then
use the arrow keys to move to the Hardware tab.
press Tab again until the Device manager button is in focus and press
on the device manager window use the arrow keys down and right to
expand the HID section and then follow the instructions above with the
