When I first turn on my laptop, the touch pad does not respond to two-finger scrolling and sometimes the touch screen does not respond too. the only problem to solve this is for me to restart my laptop every single time even though i have downloaded the latest Synaptics HID. is there any way to rectify this problem?

    My touchpad on my Aspire S7-392 has simply stopped working completely all of a sudden--no pointer on screen, nothing. I've tried uninstalling and reinstalling the driver (deleting the driver) but no joy. This is disconcerting to say the least, especially since I leave on a 4-month trip in about 26 hours...I can use the touch screen, and will try an external usb mouse tomorrow, but I'd really like my touchpad to work.

     

    Any suggestions???

     

    Thanks!

    Additional info:

     

    I've tried uninstalling, deleting drivers, downloading & installing new drivers including both the Elan & Synaptics drivers from the Acer site, and from the Synaptics site. Nothing is working. I am a former sys admin btw, so I am follwing proper protocols with reboots in between all steps, etc. Nada. on ocassion I will get a dead pointer (ie, it sits in the middle of the screen but I have no control over it fro the touchpad), but that disappears as soon as I do a right-screen swipe to get to Control Panel.

     

    This is a fully-updated 64-bit Windows 8.1 Aspire S7-392. The driver versions I have tried are:

    Elan 16.3.12.34 (from Acer site)

    Synaptics 11.6.22.201 (from Acer site)

    Synaptics 17.0.19 (from Synaptics site)

     

    At this point I'm going out to buy a compact external mouse, but I'd sure like a solution to this asap. I can't send in my system for four months, so please offer some assistance on things I can try to get the drivers to work. Using an external mouse & the touchscreen are not great options...

     

    Thanks!

    Hello, Acer tech support??? Anyone out there?

     

    I'm oh-so thrilled that I've gotten three auto-messages telling me I've got a new higher rank in the Acer community, but I'd be far more pleased with any kind of response at all from Acer support.

    I have this same problem.  updated to windows 8.1 and everything worked fine.  started installing all of the updated drivers from ACER website and now my touchpad doesnt work at all.  I've tried installed the W8 drivers, W8.1 drivers, uninstalling drivers, everything.  Also noticed FN + 2 does not start the boot menu for me...

     

    SOMEONE HELP.

    I'm not sure this is the entire answer--I tried this early on, with no results. I also btw had not attached an external mouse until after my touchpad went dead.

     

    For awhile I was just living with an external mouse (Logitech M187; I highly recommend), which was ok & I probably would have just continued with it had I not started also having problems with my screen brightness becoming unadjustable & low--the brightness function keys no longer worked, adjustments to profile power settings did nothing, and all dispay brightness controls (Windows & HP graphics card) did nothing. By tweaking contrast & other controls I was able to slightly improve the experinece, but the screen was in fact no brighter.

     

    Worse, I also started having intermittent problems with other parts of the keyboard failing (delete keys, space bar, even at one point ALL keys--at points the only input method that worked was my external mouse & the touchscreen). I was more & more convinced I had a hardware problem.

     

    So that prompted me to finally roll back to a saved configuration from two days before the touchpad problem started, something I previously avoided because of all the updates installed in the meantime and the fact that I'm now on limited shared bandwidth in a remote area (so re-doing updates will be very slow & something I'll need to do late at night to avoid sucking bandwidth from others).

     

    That solved the brightness and keyboard issues, and then I tried the F7 trick, and voila! everything was good again! Happy! Happy! Joy! Joy!

     

    Except for those hundreds of megabytes of updates I'll need to reinstall instead of sleeping. I'll try do those update reinstalls methodically, with hopes that maybe I can isolate the problem update and report on it here.

    What's the f7 trick?

    The one you referenced (http://community.acer.com/t5/Ultra-Thin/S7-392-touchpad-doesn-t-work-after-connecting-external-mouse/td-p/137131).

     

    What's weird is when I re-read that I realize I shoud have used Fn-T, since on my Aspire S7-392 it's the T key with the hand & touchpad icon, not 7 as was suggested in that other thread as possibly the key with the icon. But I didn't, I used Fn-7, to invoke what would be F7 on a regular keyboard, and that cleared up my touchpad problem. F7 turns on/off "Caret Browsing," which sounds possibly useful, but I'm not going to tempt fate right now by seeing if I can kill my touchpad again by turning that on.This has all been way too much of a time suck already.

     

    So maybe Fn-T would have worked all along. I doubt I'll ever know. But thanks for getting me to take another look at this!
