Touchpad woes on my Sony portable |
|
|
So I thought my touchpad problems had gone away when I moved to XP, and
turned down my tracking sensitivity.
but alas, my cursor was, and is again, jumping all over the screen, and
erratically right clicking, and dragging things, when I'm just trying
to plainly move the curson in one direction.
It's completely fubar, and I figured the hardware was toast, but Sony
had a knowledgebase article that describes my problem exactly.
http://129.33.22.7/SRVS/CGI-BIN/WEBCGI.EXE/,/?St=418,E=0000000000435698279,K=7389,Sxi=1,Case=obj(186352),UseTemplate=Case.tem
unfortunately their software solutions didn't solve my problem, so I'm
left with the possiblity that either the touchpad hardware is broken,
or the flex cable, or the motherboard.
So I'm thinking I'll try to snag a replacement touchpad and flex cable
off the web, and swap it in to see if it works. Anybody out there have
one to sell me?
In the mean time, I've tried my best to fully disable the busted
touchpad. I gave up on my attempts to leave the touchpad electrically
connected through the flex cable, and disabled in terms of driver
support. Leaving the thing connected with the flex cable was causing
keyboard error's durring post and XP to BSOD and restart upon loading
the alps touchpad driver apfiltr.sys.

So, much to my shagrin, I de-installed the alps drivers and yanked the
touchpad's flex cable from the board. So now I'm using an external
mouse, but yanking that flex cable, also disables my lid closed switch,
and my front speaker. What's even more perplexing, is that even with
the flex cable disconnected, I'm still getting the alps touchpad
detected at startup. Is part of the alps touchpad on the logic board
side of that flex cable? If not, I don't understand what is going on
here. Some residual presence of the disconnected hardware?
Here's the pic of what I get at bootup.

How do I tell windows to just ignor the thing for the time being
instead of noticing this new hardware on every boot? I've seen ignor
this device next time options for other things in the past, but I don't
seem to get that option here.
help / advice / commiseration are all much appreciated :-)
