Keyboard & Mouse not working window xp

By jillzq ·
One day, while I was using the computer the keyboard and mouse stop working. They were both wireless, so of course replaced batteries. Still no green light coming on from the reciever. Switched to USB mouse/keyboard. It worked then bam it happen it again. They wouldn't work. Then my whole system crashed. I put in my cd to fix the error. They keyboard/mouse wouldn't work so I can't repair it. I can't do anything. Thought maybe something wrong with usb, so I plug usb HD in that worked. Is their a solution to this problem? Please help :)
thanks

This won't help, but I have had a similar experience.

by seanferd In reply to I don't suppose you have ...

It was intermittent, and I would try switching between USB and PS/2 keyboards until something worked. Wasn't my computer, so I never saw any resolution to the problem.

But the reason you were asked specifically about a wired PS/2 keyboard is because there could be a situation where one would work even when the wireless keyboard with a PS/2 adapter would not (e.g., some sort of idiopathic RF interference).

So the upshot of that is you should at least try and borrow a PS/2 wired keyboard for fifteen minutes to see if it will work. Whether the result is positive or negative, it is still a valid diagnostic result. (You could probably buy a cheap one for ten bucks.)

Oh, and try rebooting the system twice with no mouse or keyboard attached at all, then try again.

"no green light coming on from the receiver." Either the port or receiver is bad.

How to replace/restore class filters in the registry..

by Robert_Hopkins In reply to Keyboard & Mouse not work ...

Either mount hdd in another machine or use a PS2 mouse.

-run regedit

-Navigate to HKEY_LOCAL_MACHINE\RemoteOS-HKLM-System\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}

- Look for a REG_MULTI_SZ value titled UpperFilters. If it doesn't exist, create it.

- Edit the value UpperFilters to read kbdclass. If there are any other line items in UpperFilters, delete them. (note that sometimes the upperfilter will be there, but the kbdclass description won't be. This will cause a failure to load.)

- Navigate down a bit to HKEY_LOCAL_MACHINE\RemoteOS-HKLM-System\CurrentControlSet\Control\Class\{4D36E96F-E325-11CE-BFC1-08002BE10318}

-Look for a REG_MULTI_SZ value titled UpperFilters. If it doesn't exist, create it.

= Edit the value UpperFilters to read mouclass. If there are any other line items in UpperFilters, delete them. (as with the keyboard, if the class isn't there it won't work)

- Now your usb mouse and keyboard drivers should be working again just fine. This is probably the most common cause.

Keyboard & Mouse not working window xp while watching video/movie

I had similar problem.. when I watch movie.. the mouse

pointers stop moving.. neither the keyboard nor the mouse

works.. it freezes..

Wow..the solution given by "Chicano" works.. "regedit"

In my desktop HidServ key, the Start value was 4 & I have

reset it to 2..wow.. it works.. hereagin I am repeating

his solution

"Also go to Start\Run\type "regedit" enter and check in:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

\HidUsb check the "Start" DWORD value data is 3... also

in the HidServ key, the Start value should have a 2 in

data."

Thanks Chicano
