Re: Logitech G7 Mouse problems

This is a well documented problem with the G7.  Which sucks b/c this is the best mouse I've ever used.  Thankfully though the problem appears to be the battery contacts on the inside of the mouse just get pushed back with changing the batteries.  Solutions I've read about is putting a few layers of tape on the back of the battery to push the battery further forward agaisnt the rear stop.  A drop of solder on each of the battery contacts would also do the trick, but getting the solder to stick is a trick.  (If you try this, it is very bad to heat up a battery with a soldering iron, so be extremely careful).  A better solution is to take the mouse apart, a brief overview of disembly can be found here,

Although since I didn't have teflon tape laying around...if you have used the mouse enough or just push a bit on the pads, you can see the outline of the screw holes, and just cut through the pad w/ an exacto knife.  The one under the label already had scored lines which made that one easy.  Once the cover is off I just used the tip of the exacto knife to pry the contacts out a bit more (remove the battery before disembling), cleaned the scroll wheel off, and put the mouse back together.  Works like new so far, which is good b/c from what I've heard Logitech isn't very good about replacing the mice w/o a recipt (which I think I lost after a week, nevermind 3 years).

Hope that helps, this really is the best mouse.

Re: Logitech G7 Mouse problems

I've had the now infamous G7 intermittant freezing issues for over a year now, first with XP and now with Vista 64bit on a brand new OS install (same hardware). As others have noted there is a strong consenus that this is a hardware issue potentially related to multiple factors including radio interferance, battery malfunction / contact issues, usb power, etc.

Here is a list of things to try, any of which may (or may not) solve the problem:

1) unplug the usb transmitter from the adapter and plug it back in. This did the trick for me about 50% of the time. Sometime toggling the DPI buttons (the + and - buttons on the mouse) up and down also helps.
2) if the freeze gets so bad that the cursor wouldn't move try shutting down the PC, unplugging the cord to the power supply, toggling the power supply switch to discharge the motherboard capacitors, then turn on the PC and reboot.
3) clean the battery contacts. Remove the battery and use one side of a Q-tip soaked in isopropanol and clean the contacts on the battery and inside the mouse (the 3 prongs sticking out of the end of the battery slot). Make sure to use the dry end of the Q-tip to remove all of the isopropanol before sticking the battery back into the mouse.

4) if the transmitter is near a wireless router or other transmitter (bluetooth radio, modem, etc.) place it as far away from these devices as possible.

Re: Logitech G7 Mouse problems

Had the same problem, contacted Logitech and they had me do the usual troubleshooting steps (try it on another computer, make sure most up to date software, does it happen in multiple programs, etc.), which i had already done but humored them nonetheless and they ultimately decided it was a hardware failure and sent me a new one. There is a 3 year warranty on the mouse from logitech so if you still have the receipt (or in my case the online retailer still had my invoice history) then with a little bit of work you can get a new mouse. Best of luck.

I use a Logitech G7 Laser cordless (RF) gaming mouse. The operation has become intermittent, with the mouse freezing, sometime every couple of seconds, sometimes every couple of minutes. I normally use...

It's possible the Firefly remote is interfering. It's also possible the mouse is going bad (G7s have been around for a while). I'd contact Logitech and see what they can do for you - their warranty support for mice is terrific.

Logitech mouse frozen up we changed batterys in

If the mouse is freezing up though the batteries are fully charged, here's what you need to do:

1. Try to use different batteries just to make sure that it's not a power issue.
2. Connect the wireless USB dongle into different USB ports of the computer.
3. Try to connect the USB dongle in different computer and try to use the mouse (to make sure that it's not a computer issue).
4. Make sure that there's no cordless phone, cell phone and other wireless devices that might interfere the wireless signal.

The Logitech wireless mouse is running on 2.4MHz frequency, same frequency as the other wireless devices. Any wireless device might cause the mouse to freeze.

If same problem occur, then it's a hardware problem. Contact Logitech and RMA the mouse.

Thank you and good luck!

Mouse Is Recongnized but wont Move

On the bottom of the mouse is a little tiny button that say: connect or reconnect. Place the mouse close to the transmitter dongle (the do hicky comes out of a USB) and look for that button on the transmitter and the mouse to reconnect the signal.
(batteries are good ?)

My wireless mouse freezes

I had a similar freezing problem with a wireless Logitech mouse and also a problem with the wireless keyboard, sometimes keystrokes would not register and sometimes they'd repeat a dozen times.
I was not able to fix the problem, so I got a Microsoft wireless mouse and keyboard, hoping it was a driver conflict that wouldn't affect both products. Wrong. The exact same thing happened to the Microsoft mouse and keyboard.
The cause of the problem turned out be that I had the receiver plugged into a USB hub along with several other devices. Moving the receiver to one of the USB ports in the back of the PC fixed the problem.
Apparently these wireless desktop devices don't like sharing USB resources with anything else.

Wireless keyboard and optical mouse

Thanks! I fixed the problem by installing a USB mouse and using fn+f9. That unlocked the mouse so I could use the pointer leaving just the keyboard problem. I then tried reconnecting the wireless keyboard (by using the button on the receiver and under the keyboard) Hey Presto!!

When this behavior is observed when using a Logitech product withinWindows® XP, it may be caused by a feature within Windows called"enhanced pointer precision". This feature may conflict with Logitech's software, causing the erratic movement. Enhanced pointerprecision became available in Service Pack 2 and therefore is notapplicable in any version of Windows® XP without Service Pack 2installed. For more information on enhanced pointer precision,please click HERE. If this link does not work, then you should go to Microsoft and search for Knowledge Base article 895550.

Please see these articles from the Logitech database for possible troubleshooting tips as well:
