The "left mouse button" in my Fujitsu Lifebook A1110 became flakier and flakier over the last month, and now produces no reactions at all. I've done a few things to try to diagnose & fix the problem, but the best I've come up with is a workaround. Here's my list so far:
1) Searched the web to find info, and either I didn't use the same words as anyone else, or there just isn't any info on Fujitsu Lifebook mouse buttons.
2) Clicked left then right buttons to verify they both depressed and released the same - I could not hear or feel a difference between them.
3) Looked for newer mouse drivers - did not find any through Windows, Belarc Advisor or WinDrivers.com..
3) Used "Mouse" in "Control Panel" to switch button functions - the problem stayed with the button not the function: I'm now "clicking" with the right-hand built-in button.
4) Verified a USB mouse works normally. By this point, I'm pretty sure it's hardware in the laptop causing the problem.
5) Searched the web again for info on disassembling Lifebook computers, and found nothing for the A1110.
6) Gave up, grit my teeth, and took the laptop bottom cover off and cleaned out the insides (I would never have guessed cat hair could get into a notebook!!). I was not able to completely take it apart - there were connectors I could not find or figure out, but as far as I could tell, both buttons and the board they reach down to were cleaned and undamaged. It now runs cooler, but the button still won't work. (I'll post a thread on that dissambly tomorrow evening.)
I'm currently using the switched built-in button function so I can click without relying on a separate mouse.
Any ideas about places to find more info, things to try, etc?
