    I decided to make this troubleshooting post about ours buggy touchpad behavior since there are many information spread across different posts in non-touchpad related topics.


    Symptoms


    Not all G73 are affected by this issue and the symptoms can be different for many users, but most of them are common as:

    • The touchpad work perfectly for minutes to hours, then all of a sudden go really laggy.
    • The touchpad refuses to move, pass or go after certain point, usually the center area.
    • Just not respond to movements in certain directions.
    • Some parts of the touchpad send the pointer to the right.
    • It can jump around the screen.
    • This issue can las for hours and is solved with a restart.
    • Happens with/without synaptic driver, with multitouch both enable or disable.
    • Sometimes even the cursor move by itself.


    As part of my debugging analysis, I conclude all the problems of the keyboard and touchpad came with the BIOS update. I received my unit with 206 from factory. Upon received, I installed the touchpad driver 15.0.0.9 (non asus) to enjoy the two finger scroll feature (not available in asus package.... do not why!?!?!). everything was fine until update to BIO 209 when the problem appears, but, since I used to use mouse, the touchpad was not very noticeable. Now I'm using only the touchpad but I can't go back since I'm in vBIOS v93 with BIOS 211. By the way, my touchpad hardware ID is: ACPI/SYN0A06

    The problems seem not to be attached to any specific driver version, since both me and others had reported using different from the official asus with the same buggy issue. I just tested many different touchpad driver packages (from asus and others), with two finger and without them, but the problem persist. The only thing that gives a little hope is that the Microsoft driver has no this problem but you lose all the synaptic features.

    The drivers tested so far:

    • 14.0.10.0 from asus (without two finger scroll enable in touchpad control panel)
    • 14.0.10.0 generic from synaptic (without two finger scroll enable in touchpad control panel)
    • 15.0.9.0 generic from synaptic (Two finger enable)
    • 15.0.10.0 generic from synaptic (Two finger enable)
    • 15.0.20.0 generic from synaptic (Two finger enable)
    • 15.0.24.0 generic from synaptic (Two finger enable)
    • 14.0.3.C Latest from synaptic website (Two finger enable)
    • 15.0.11.0 from asus G73JW (without two finger scroll enable in touchpad control panel)

    All of them has the same issue, which seem to be a problem independent of the driver version, since much of them are generic and work perfect in different laptop with synaptic built-in touchpads. By this, IMO, the solution won't be found in a custom synaptic driver specif for the G73. I'm currently using the JW touchpad drivers which as well as the rest of the drivers, the issue is present. This drivers set has no Two Finger Scroll (don't know why?) and to enable it I just use TwoFingerScroolApp which enable this function in all synaptic touchpads. The only reason I do not remove the synaptic drivers is because I'm addict to Two Scroll Finger feature, in addition to the touchpad behave weird with generic MS drivers,

    Me and other here are stated the problems should be the the polling rate for the touchpad. I already test my poll rates and they are around 80 hz for the touchpad and 120 hz for the mouse. When the touchpad freezes, the rate freezes too and when the functionality return, the touchpad poll rate return to 80 hz. The point is, to touchpad stops reading the inputs and do not change the sensibility, is like working or not, but no middle points in this case. Also, I read elsewhere to change the poll rate may led to system instability since it also change the frequency of internal chips read the peripherals, leading to asynchronous components' communications.

    All these issues are independent of the KBfilter installed (driver for the keyboard). Using the MS default generic driver or the asus one, the issues persists. The Atk also does not solve the touchpad problems because is just the app which controls both the Fn and lights keys. As observation, after removing the kbfilter, not keyboard function where lost and my touchpad feels a way smoother when I use it.

    I realized when a use my g73 on my laps, the problem came often. When I put on my desk, the issue gone. Is like if you use the laptop in other position than horizontal (laps, bed, sofa) the touchpad issue return. I'm not saying if you move the laptop the problem appears immediately, but long periods on my laps the issue seem to be more frequently. But later, when I used to laptop in my laps/sofa, the touchpad retakes its jumping behavior and became (as always) useless.


    Partial Solutions

    Looking for a solution, I found a simple but partial solution (in addition to use a mouse). Just opening the Moodpad (from the taskbar touchpad icon->Synaptic->accessories->Moodpad) and leave it always visible, solve partially the strange movement. Also, you will notice the app shows pressure in areas different that the one are you actually pressing. In my case, use to happens when I press the center area my finger appears to the right and it can not pass the center of the touchpad. I can even see how the ghost finger is moving by itself.

    Other way to solve this issue is just restarting the driver. Open the mouse properties->synaptic tab-> restart the driver (on the button). It solved, but the solution last for a while.

    No way to override it from the control panel or device manager. I'm looking into modifying drivers or something about PS/2 conection wich seem to be the problem since removing kbfilter the touchpad feels better and no problem is shown without the synaptic drivers.

    This information was posted some weeks ago at Asus FAQ section for the G73 laptops.


    For any update/solution I'll update the post often.

    And Gary, if you read this let know the R&D guys take a look in the BIOS (206 vs 209/211), seems to be hardware controller problem more than a soft issue.

    I've also messed around with various drivers and found that the HP Synaptic driver version 15.0.9.0 seemed to improve things for me, haven't noticed the annoying "sticking" since I installed it. It has all the gestures: 2 finger scrolling; 3 finger swipe; rotation and pinch to zoom, although I disabled zoom as it accidentally activated too often.

    I'm running BIOS 211, the track pad ID is also ACPI/SYN0A06

    I know it's been a while, but has there been an official fix for this issue?

    Mkeeley, thanks for the info on the HP 15.0.9.0 drivers as this seems to have stabilized things for me. It was driving me nuts prior to the driver change. I think it even works better than previous driver.

    This problem just occurred a few days ago for me, but it's getting worse. A couple of hours ago I had to restart because my mouse cursor was disappearing entirely. Given that the cursor disappeared, I can see why Asus is pointing to VGA drivers, but I don't have time to go through all the necessary troubleshooting right now.

    Only a few days left on my warranty so I need to decide soon if I want this RMA'd or if it's even a possibility.

    Other function I've lost includes some of the custom corner actions I enabled, specifically in the lower left and upper left corners. I'm also getting the ghost finger that scrolls on its own across from the left to the right. Always in this direction, it never scrolls right to left on its own. I'm slightly fascinated by that.

    Thanks Nekki for the dedicated thread. I hope people can find it easily and maybe we can get some good info nailed down for this issue just like the keyboard lag people have been trying to do. Although I have this touchpad issue, I don't have keyboard lag, at least as far as I know right now. I'll certainly update if that changes.

    I'm putting up a post about using a beta Intel INF package to perhaps fix this issue.

    Really? The problem appeared in 209? I never had any GSODs with any BIOS. I guess I could go back to 206 and see if my keyboard lag goes away. I'm trying to remember what fixes there were. I think 209 fixed Fn + Esc hanging the computer which is no big deal. I had never pressed that combo anyway. The big issue I think was the performance dropping badly if your battery got below 40% and then not coming back up without a reboot.

    New info about the touchpad:

    Regardless Gary insists it's a synaptic problem, I tested many synaptic packages (non-asus-non-twofingerscroll of course) in my old (but still rock solid) asus w2pb. As you can guess, the touchpad perform excellent, with no lag/buggy/non-responsive strokes. So, why insists in look for in synaptics driver a solution if the issue is relative to system/controller of the JH itself. Keep in mind guys the touchpad work perfect for min to hours before to become faulty. It's like something in the control system which is making the driver become faulty.

    Again, I hope all this information help to asus techs find the solution.

    I tried Bios 206, 209 and 211 with even more Synaptics drivers as you Nekki (i tried every possible driver i could find) and it made no difference...
    I cant say if its the Synaptics driver, some other Asus related driver/software or perhaps even hardware, but whats clear is: these problems only occur with the Synaptics driver installed, and the same synaptics drivers work fine on other laptops, they just dont work right on the G73 series, and to complicate it further, even on the G73 laptops roughly 40% users are problem free according to the poll that was posted here.

    Whatever solution Gary/Asus is working on should really be released soon if theyre half serious about this, especially seeing the G73JW also "inherited" this problem as it is even noted in the review on notebookcheck.

    I tried use my system without the synaptics drivers, but since TwoFingerScroll needs the drivers install to activate the two finger, at the end I'm coming back to synaptics. In addition, the touchpad with generic MS drivers perform awful. :mad: ... but works :rolleyes:
