Acer Aspire E 11 ES1-111M-C72R: which touchpad driver?

Natey2

I have the ES1-111M-C72R. Should I use the Synaptics or ElanTech touchpad driver?

Will the "wrong" driver not work at all, or just operate partially?

Machine came with Windows 8.1. Now running Windows 10.

Hi,

Go to Device manager, expand Human Interface devices, expand Mice and other pointing Devices, check whether you have Synaptics or Elantech as in my snip.

No such indicator there:

Hi,

You have to expand Mice and other pointing Devices.

Despite what it says below, there is no attached PS/2 mouse, except the touchpad:

Hi,

Go to Device manager, highlight and right click Splashtop Virtual HID, go to Properties then Details tab, select Hardware IDs from the dropdown menu and check whether it mentioned in there.

(It is remote control software, like VNC)

 

I've been reading in these forums that some people with a similar laptop are loading Windows 8.1 64-bit drivers in a Windows 10 64-bit OS environment. Should I try the Serial IO drivers and the Intel Chispet drivers from Windows 8.1 64-bit? Maybe it will correctly identify the touchpad hardware then.

 

The touchpad in my current setup works for a while, then locks up. I have to frequently do Fn+7 twice to get it to work again for a short while.

Hi,

Yes, you could reinstall the driver for Serial IO and chipset but make sure you create a backup of your sytem or create a system restore point.

I used Speccy 1.30, and the Vendor indicates "SYN".

So Synaptics, I think.

Mouse Vendor is "SYN". So Touchpad is Synaptics?

Hi,

Yes, good find, it looks like Synaptics

I installed the Windows 10 64-bit Synaptics driver (install said successful), rebooted the laptop, and nothing under the Device Manager's Human Interface Devices has changed.

I checked and I have the latest Intel Serial IO drivers for Windows 10: v604.10135.1001.53001

Hi,

Could you please try switching to Basic mode from Advanced mode in BIOS and install the driver, go to BIOS setting, move to Main tab, scroll down to Touchpad and change(if it's available).

Natey2

The BIOS setting for the Touchpad was at Basic.
I changed it to Advanced and the Synaptics entry appears in the Human Interface Devices list:

 

 

Speccy report:

Note the new Mouse parameters

 

But the touchpad pointer was still locking up.
So I downgraded the Windows 10 64-bit Intel Serial IO driver from v604.10135.1001.53001 to the Windows 8.1 64-bit Intel Serial IO driver v603.9600.1948.28229 (I believe this was mentioned in another thread here) , and everything appears to be working fine now; the pointer doesn't lock up.

I also notice that my CPU usage has gone down noticeably:

CPU usage, by Core
In the past, even a small operation will peg both cores at 100%.
The combination of the Win 10 Serial IO driver and/or the Basic Touchpad BIOS setting may have contributed to that.

 

Note: I am at BIOS v1.10, not v1.16 (which appears to be the latest at this point in time)

I'm glad you got it sorted
