E5-575-33bm laggy bad touchpad

teatimecrumpet · December 2016

Hi, it is my second day with my E5-575-33bm. My touchpad is slow and lags across the screen. Sometimes it won't respond for half a second but will after I do the same direction. I see the problem happen the most when moving across the screen and trying to drag a window bar down. Multi-touch scrolling seems to work.

I tried to change my BIOS setting for the touchpad to Basic but obviously will lose multi-touch. It's moving better and at a constant speed and doesn't seem to be losing response but the speed is slow and can't be changed.

I notice that CPU usage will jump up by ~15% when using the touchpad.

I have the most up to date drivers for the touchpad.

Is something wrong with my hardware? Should I return and try to roll the dice? Is there an alternative driver anyone recommends?

Hi,

Have you tried changing the cursor speed? If not, give this a try, Start and go to Settings, Devices, select touchpad and adjust the speed of the cursor.

THanks, I have tried to max out the speed of the cursor but once I try to do a smaller adjustment to say ex out a window or grab a scroll bar it takes some time to get there. I'll spend a second or two just watching a stuck cursor while I move my finger in very small increments on the touchpad. When this happens, sometimes I'll just give up and make larger motions randomly around the screen and try to get at what I was originally going for.

I suspect the touchpad itself is poorly designed and the ELAN drivers aren't matched properly for the poor material being used because I notice my finger will get caught on the touchpad and a stutter happens.

Is there other drivers I could use with the touchpad or have basic but be able to control the cursor speed?

Hi,

This is because of the driver conflict between HID-compliant touchpad driver and Elantech driver, could you please post the snip of your Device manager showing Mouse and Pointing device expanded.

You can either use Precision Touchpad or Elantech.

Yes, that's what I thought, you could try going to BIOS setting and switch Touchpad mode to Basic from Advanced, that will disable your Precision Touchpad and you can continue to use Elantech.

EDIT: Sorry, by mistake I requested to expand Network adapters(it's almost my bed time Smiley LOL

Thanks, I tried going to basic and it worked better but the cursor speed is still slow and can't bbe modified. You also lose all the touch features.

Is there some other generic or branded driver that I can use that might work better?

Hi,

Could you please post the ELANTECH window and does it give you any options to change gestures, do you get a window like mine? Also get the latest driver from acer site for Elantech and reinstall:https://www.acer.com/ac/en/GB/content/support-product/6752?b=1

After installing the driver, go back to BIOS and switch to Advanced mode.
