Batteries died so replaced them but now mouse doesn't work

All I can tell you that you should check with a new set of batterie.
If still your wireless mouse refuses to work, consider it lost,
Personally I HATE WIRELESS MICE. Had 3, all of them died prematurely. Lost money!!!

Mouse may be dying or the USB port needs update. If you can borrow a mouse or purchase a news one to test. If you need to update USB driver go online to see how to do that. I would bet IRS just the mouse.

Try rebooting system. Also make sure it (the mouse) was installed correctly

You haven't said what kind of mouse you have or whether it used to work.
I'll offer some suggestions for the most common problems:
If it used to work but now doesn't, try a system restore back to when it did work.
If that doesn't work--are you using a wireless mouse? If so, are the batteries fresh and are they inserted correctly?
If you are using a wireless mouse, have you pushed the little "connect" button on the bottom?
You haven't said, but is the other mouse a wireless one or a USB mouse? If your USB mouse doesn't work, try another USB port. If you go into the device manager, do you see a "human interface device" or a "mouse" listed? If so, it will tell you the system recognizes the device. If that is missing, there is a good chance the mouse is dead.

Hi,
According to your problem, If you can't access your mouse in your then first check the receiver battery of the mouse is OK. Try to update the external device driver from device manager.You can also try download the device driver from the product website. If it doesn't't help you then replace the mouse.

You also need to click on the receiver button. After the receiver button is clicked then you would need to click the mouse button located under the mouse. If all of this was done try replacing the batteries again with a new set of batteries. I've seen new batteries not work before that has died while sitting in it's package.

I'm sorry for the demise of ur mouse, I pay my solemn respects to it.
I kindly ask u to burry it in ur backyard

This can happen when the battery's are starting to die. Replace the batteries and then test the device again.

check your batterys with a flashlight after that push the buton on your recever. then push the keyboad reset and last do the mouse. if that don't do it switch and do the mouse first then the key board. keep close to the recever it works better

Did you check the batteries to see if they are good. Some individuals are having to replace the batteries sooner then they should have to. Good place to start. Hope this helps. Bud
