Tip & How-To about Dell M787C Wireless Mouse P/N: M787C - Originals
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
