SOURCE: After I changed that bateries

Please read complete post before beginning. I am offering more than one solution,

Try reinstalling your mouse with the disc that came with it. You should be able to simply place the disc in the drive and click install. If you do not have the disc. You could try going to:
> Control Panel
>Depending upon the version of windows you use, (you may find the install/uninstall in different places)
> Click on Uninstall
> Click on the mouse program in the menu that pops up...be very cautious here so that you do not acciddentally uninstall a program that you want or need.
You will be given the option to uninstall/repair/install
> Click on repair.
---------------------------------------------
You might also click
>Start
>In the search box type compatibility issues
Open whatever file it gives you and check for issues for your mouse or keyboard.
Finally, check again whether the batteries are actually good. ( I would bet you have already done this)
----------------------------------------------
>Right click on my computer
>Right click on Properties
>Click on Device Manager
>find your mouse in this list(usually mouse and pointing devices)
>Right click the correct mouse
>Click Update driver and follow instructions from there.Click on search my computer for device driver first try. ( you may or may not need an update.
If neither of these options work: please write back with your operating system ( windows 7, Vista 32 or 64/windows Xp, etc. and also the make of your keyboard and model numbers if you have them.

Tip

Dell wireless mouse M787C batteries are wired in Parallel not in series...


Hello All, I just received a Dell All in One Computer with the M787c wireless mouse. I installed 2 fresh batteries and noticed after 3-4 minutes one of the batteries was getting warm? I removed that battery and the mouse LED light was still working. SO the M787c mouse was working as it should with only ONE Battery!
I checked wiring of the batteries and found that the Batteries were WIRED in Parallel. Wiring batteries in parallel is not a very good Electrical practice, at all!
I am sure that many owners of this mouse have gone through many batteries because of the miss wiring.
If you mouse does not work with properly with one battery if you are mechanically inclined you can disassemble the Mouse and rewire the batteries in SERIES.
There are 4 screws on the bottom of the mouse, 2 in the bottom underneath the front gliders, and 2 in the top. Happy fixing. Rob

My Dell wireless keyboard doesn't work. I replaced the batteries in it and pressed the green button on the back of it then the button on the wireless thing plugged into the computer. That light blinks for a few seconds then stops but the keyboard still doesn't work. My wireless mouse works fine.
