Mac Forum / General / Portable Macs / August 2004pismo trackpad question: hardware, software?
This 400mhz Pismo is getting erratic: I can't always control where the cursor moves, whether it moves at all. Sometimes it wants to select the entire line I'm on, or all the lines to which I move above or below the cursor. I'm really talking more about the clicker, not the trackpad itself, I think, and I suspect it's hardware, not software, although I wondered if something like a new install of setiathome is taking over, as if the machine is simply slow to respond.. Rebooting has helped a little, but rapping hard on the clicker seems surer. Possible to install a new trackpad assembly if my only experience is new RAM? Expensive to send out for replacement?

The trackpad clicker had been intermittent, then tonight it was gone entirely, but later I could use a USB Microsoft mouse on it OK. I wrote a sentence here, unplugged the mouse and the clicker worked for a few clicks, then quit again. Wrote the next sentence with the USB mouse plugged in, removed it again, the trackpad is working again....wish it would make up its mind. I know its screwed up when I have text on the screen; it acts as if the clicker is down and a moving finger on the trackpad starts selecting text. Any suggestions short of sending this machine out for repair? SignatureBob Ball If you want to think positive thoughts, surround yourself with positive people.

I had a similar problem a little while ago on my Pismo and I ended up replacing the top case which houses the trackpad assembly and never had any problem since. -Laurent.

Replacing it myself is somewhere past my comfort level, so I may send the Pismo to AZ and have them replace it. The hinge is getting a little loose; I might fix that as well and perhaps the repair will then exceed the value of the machine. That's OK; my wife wants a G4 iBook for Christmas; maybe by then the G5 iBooks will be ready and proven. > I had a similar problem a little while ago on my Pismo and I ended up > replacing the top case which houses the trackpad assembly and never had any > problem since. > > -Laurent.

You can pick up a used top case on eBay for $10. With a torx T8, the service manual and a little care & patience the job can be done in well under an hour. The Pismo is very good to work with: no snipping or gluing required. If the actual clicker mechanism, rather than the button, is the problem, then a new Power card might do the trick as it houses the clicker component. Around $25 on eBay. My recommendation is first to get the Torx and check the trackpad connector is firmly seated.

I think it's a good idea to check the connector. Replacing the top case requires to completely take the Pismo apart, including the screen. Granted, the Pismo is easy to work but there is still a lot of screws and parts to remove and then put back. -Laurent.
