G73JH Touchpad Problem After BIOS Flash Fixed (in my case)

When I got my G73JH-A2 this last June from Amazon, it came with bios 206. All was working flawlessly for the past 6 months especially the touchpad. Just this January, I've decided to flash my bios with 211. After successfully flashing, I logged-in to Windows and after a couple of minutes, I've noticed my touchpad was acting weird.

Using only a single finger (no other parts of my hand touching the palm rest or touchpad), the mouse cursor somewhat changes to a four-directional arrow cursor wherein moving it either zooms-in or zooms-out depending on where you are, which is just like the pinch-zoom (browser: page zooms-in or zooms-out, desktop:icons zooms-in or zooms-out). On other times, the cursor just stops moving when you are actually swinging your finger on the touchpad. On other times too, when using vertical scroll bar, scrolling downwards moves the cursor from its position to the lower right part of the screen.

I've searched here at NBR if I'm not alone with this problem then I've learned that there's plenty of people having this issue. I asked my brother if he have encountered this on his G73JH-A2 and there I've learned that after he flashed his bios from 206 to 209, his touchpad acted weird too by acting like a pinch-zoom on random times.

He had managed to fix his problem by uninstalling his Synaptics driver and reinstalling the 14.0.10.0 one from the Asus G73JH download page.

Learning this from him, I tried to uninstall the Synaptics software then rebooted. After logging again to Windows, I've noticed that Windows installed its default touchpad driver wherein functions like pinch-zoom, vertical/horizontal scroll bar don't work. There I installed the Synaptics driver (the 14.0.10.0 one which is my stock Synaptics driver too, the one I just uninstalled) from the Asus Driver CD then rebooted. After rebooting, I've never again encountered the problems I've mentioned.

I've been using my G73JH-A2 for 4 days now and 100% touchpad-issue free from this time of writing.

If ever you wan't to try the one that came from the Asus Driver CD instead from the one on the Asus G73JH Download page, I've uploaded it on here: Synaptics.zip

 

hmm so you are telling that with bios 209 and 211 your touchpad started acting crazy
but with bios 206 it is fine?

someone mentioned that 206 and gary's vbios is not recomended
what about you?
i am with 211 and gary's vbios and my touchpad is fine but sometimes freaks me up with resizing

 

What I mean is that right after flashing the bios, the touchpad became problematic.

Now I'm on bios 211, and after I did what I've just mentioned (basically unistalled the synaptics driver, rebooted, installed the synaptics driver 14.0.10.0, then rebooted, then that's all, nothing more nothing less), the touchpad is back to normal.

 

Jehuty, version 14.0.10.0 is a very old version. I doubt (and I could be wrong) that that version has all the fancy gestures and movements available with that version.

I have version 15.1.16.2. I'm curious now though, if u are on bios 211, and since u say your touch pad works fine on driver version 14, u think u can try installing version 15 and see if it works for you?

If it does, then it very well could be hardware perhaps. What other factors are there? bios, drivers...you have the A2, I have the A1.....

edit - or perhaps u haven't spend too long yet on bios 211 and the touch pad yet?

 

what version of synaptics did you have then
so after flashing to 211 problems with touchpad appeared with what driver?
and you solved it just wit uninstalling and installing 14.0.10.0

i've tried both and that driver from the disk is better (14.0.3.0)
it has more options...

 

O, so u got driver version 14 as well and it still screws you over? forget what I said then about hardware. Its probably better if I shut up now since there has been a huge debate over weather its hardware or software.

Hope its software related and all we need is an update.

 

@ Xellon i am using version 15 right now with all the gestures and it screws me over sometimes but rarelly
although i can't remember about version 14
i will install it these days

 

What happens with the new bios if you use the default MS driver (no multitouch)?

 

I've read about that somewhere.... I think I read different answers, it works, or it doesn't.

edit - o wait, u mean the new beta bios? No idea.. never heard of anyone trying it on the beta.

 

i don't know if it will work with those beta releases (haven't tried them) but i know that if you are with MS driver your mouse is slower ... probably you won't have scroling ...multitouch ...all those gestures

 

Yeah, but will you have crazy drunken frat-boy mouse movements?

 

lol, only one way to find out. you can give it a shot or wait for someone else to do it. I won't cause I'm lazy.

 

what's so hard ...you don't even need to uninstall synaptics
update driver -> let me choose what to pick -> and choose microsoft driver\
now test

i will try 14.0.3.0 these days if it is better

 

I'll try to install a Synaptics 15.something sometime, maybe after 10 days to check if 14.0.10.0 made my touchpad fixed. I just flashed my bios from 206 to 211 just this first week of January and from that moment, after rebooting and few minutes, I've noticed the annoying touchpad problem. Just after I've done what I've said on my first post (because my brother did it and he said it fixed his G73JH-A2 touchpad), my touchpad shows no sign of its mentioned problems up to now (4 days and counting).

Yes after flashing to 211 the problems just appeared. On my brother's case, he flashed from 206 to 209 then the same problems showed up on his beast. My stock Synaptics driver is 14.0.10.0, I just uninstalled it, rebooted (Windows installed its own touchpad driver where my touchpad showed more problems compared than before), installed it, then rebooted again. 14.0.10.0 is the one that came with my Asus Drivers Disk.

The touchpad became more problematic with the default MS driver, showing the following:

Touchpad doesn't allow me to swing the cursor towards the left direction, unless I click a right-click, then that's the only moment I can swing towards left. The cursor also became slow when I'm swinging my finger. No Vertical/Horizontal Scrolling and Pinch-zoom too. Those are my observations when I've uninstalled Synaptics 14.0.10.0. I only use Vertical/Horizontal Scrolling and Pinch-zoom so that's the only gestures that I've managed to see if it's working. I just learned ChimeralMotion after I've installed 14.0.10.0 again.
