Thank you! I like this mouse very much, but the left button microswitch stopped working gradually. Now that I found a cheap 'donor' I proceeded to fix the mouse with this help. But a little pin, shaped somewhat like a little black plastic spinner, felt from the mouse and i don't know where it goes. I think I can see it in image 16 laying just between the circuit board and the screw socket you can see on the bottom left. What's this?
okay, i too managed to dismantle my ineffective mouse. Any ideas how i figure out which bit is broke, how i can repair it, and how it assembles again.mike
Image 17 shows the simple wire antenna running round the front of the circuit board, connected between ANT & ANT2 as marked on the other side of the circuit board - the funny shiny bumps on the other side are where the wire has been soldered through the board in a loop. Mystery solved, don't know why I missed it the first time. Keep up the good work.
Image 16 actually shows the +ve battery terminal. The antenna is seen on image 15 - halfway up the r/h side of the circuit board, clearly marked as "ANT". Apart from that a great article.
I haven't had much luck re-assembling electronics items I've taken apart. With the exception of my Palm Treo, typically the process of disassembly precludes returning the unit to operation. That said, if the item's been very carefully disassembled, it's possible you have a chance. As for determining which component has failed, that will likely prove much more difficult. Good luck, though!
That's my mistake on the positive battery terminal. My apologies. The antenna is, indeed, in image 15. Sorry! Thanks for the kudos on the rest of the gallery. I appreciate it! Erik Eckel
No, you are correct, the metallic coil standing off the board is the (+) Positive Battery Post... This is a clear example of why you can trust about 30% of what you find on the web, even on trusted sources like TechRepublic. This one even got past the editors.
That terminal looks just like the wireless antenna to a lot of satellite station remote controls and network extenders. Besides if your not onto wiring diagrams and schematics it is an honest mistake.
According to the circuit board markings the antenna is up there near L4 on the center right. That relatively large round object to the upper left of that mark looks more like it. It looks just like a miniurized version of a large glass modulator I used to work on. Would you be able to tell? Perhaps it is the tiny object at the lower right of the "ant" mark. Just curious. I'm pretty sure that L4 is actually the red copper inductor directly to the left of the L4 mark.
I have a MS Wireless Optical Mouse 4000 which is similar to the 3000 described in these pictures. One major difference is that not only does it have the normal scroll wheel but a "tilt" function associated with it that allows left and right scrolling as well. I love this optical mouse. It's better than any other one I have ever used. I even got one for my wife's computer. She loves it, too.
I have been using one of these for several months. I love it. It works consistantly, batteries last forever if you shut them off by inserting the USB dongle back into the mouse's bottome when you put it away. I have no trouble with it in any way.
I wouldn't think so, although I certainly know some people who would espouse that litany. My experience with MS-Branded hardware has been quite good and their HARDWARE tech support is light years ahead of their joke of a software tech support operation (other than always requiring the complete zillion digit serial number which is printed in microscopic type on the product). Apparently whichever MS flack wrote the descriptions for these photos thought pretty highly of his boss's product - I've seen press releases that used less puffery than the descriptions in this article.
output or vice-a-versa. Or signal swapping when not syncronized. Just guessing. Interesting though. (edited) input and output it is! From one end to the other; underneath the circuit board.
I also have a 4000 with my notebook. Love it - only problem is it's a little smallish and makes my hand cramp a little during long sessions. It's a very reliable mouse - but I moved to Vista and I should check back about updated software for it. Not only is there the tilt scrolling but the tiny zoom button on the left side of the mouse body allows you to activate a zoom window and size it to enlarge text on the screen.
My husband and I have both used this mouse and have not had any problems. He insisted on paying $10 to $15 more than the other brand they had at the store. I think we've had them for close to 4 years now.
I got a buggy laptop mouse once and when I phoned Microsoft support and went through a short quick proceedure to make sure the thing didn't actually work. They send me a new one - pronto! They didn't even want the old one back! I have since been buying their products exclusively because I've had support problems from the other companies.
