I have a Logitech wireless mouse DH931435 that has started to give me problems....the scrolling wheel only turns one way with great difficulty and the right and left click are very stiff....what can I do?

you will need to purchase the set as the transceiver is paired with each - saw units on ebay starting at $30 and it appears Best Buy has them at ~$50

Shortcut : Window Key + R
Run: Regedit
User Key: [HKEY_CURRENT_USER\Control Panel\Desktop]
Value Name: WheelScrollLines
Data Type: REG_SZ (String Value)
Value Data: 0 - 0xFFFFFFFF

A different driver or replace wireless mouse hardware

There are number of reasons and solutions why your mouse isn't working properly. No.1. Resynchronize your mouse to the Pc. It's best to use the reset button for resynchronization. No. 2. Change the Port (Usb port). Sometimes even the small problem with the port created this problem. No.3. Replace the battery. If you are sure about the battery is Live, you can try with another make eg. Sony to Everydy. No.4. Interfaces Problem. Make sure that no electronic items, metal box, Speaker, etc doesn't obstruct the connection. No.5. Driver Update. Update the driver to the latest version. You must update from the particular website. If you are using Microsoft product, you must update the driver from the Microsoft's website. No.6. Different System. Try out the device on several devices not only one. If you still have difficulty, you can visit this site for more details. http://support.microsoft.com/kb/838398 Good luck

Hello there:
If you remove the battery cover you will see 2 small phillips head screws remove them and this will allow the part that goes around the wheel to be removed now make sure that there is no lint or dust build up around the wheel assembly canned air works great for cleaning these out then reassemble the cover and test
Now if it still doesent work than you can assume that the controle sensor for the wheel is bad in this case if you still have the warranty i would take the mouse back and exchange it for a new one
To have this repaired would cost more than what the mouse is worth ok
I hope this is very helpful for you
Best regards Michael

THIS MAYBE A WINDOWS DEFENDER AND WINDOWS FIREWALL ISSUE, DIS ABLE ALL TO SEE IF IF IS THE PROBLEM.

TRY GO THREW ADDING NEW DEVICES IN THE CONTROL PANEL.

WHERE THEY WORKING BEFORE AND YOU UPDATED THEM AND STARTED HAVING ISSUE, ROLL BACK THE UPDATES.

MAYBE IRQ AND DMA ISSUES, DEVICE MANAGER IN THE CONTROL PANEL MAY HELP.

ROD

go to control panel and go to mouse then wheels and see what you have it set on for line per scroll.. mine is set for 3 lines hope this helps

At the rear of the mouse you will find a button , push the button and pull the top thing it will come out (it is in a straight line from scroll wheel ) and then you can change the battery
