Issues with touchpad responsiveness and lag on the Acer Aspire 7 (A715-51G-74CX) – looking for a lasting solution.
Hi everyone, I’m using an Acer Aspire 7 (A715-51G-74CX) and have encountered a problem where the touchpad becomes slow or unresponsive at unpredictable moments. The clicks still function, but the cursor feels delayed or overly heavy, making it hard to track touch in real time.
I’ve tried switching the touchpad on and off using the F10 key, which temporarily resolves the issue (it works normally afterward), though the problem eventually reappears.
In Device Manager, the touchpad driver is listed as ELAN I2C Filter Driver. I’ve downloaded and installed the latest ELANTECH driver (v13.6.21.1) from Acer’s support site. I also turned off the “Allow the computer to turn off this device to save power” setting in Power Management. After rebooting, the driver appears installed correctly, but the lag still occurs randomly.
Could this be related to a BIOS update? Or should I consider changing the touchpad mode (I2C to PS/2) in BIOS if possible? Any advice or solutions would be greatly appreciated.
Thanks in advance!
Welcome to the forums, newcomer! I'll check if your laptop needs any BIOS updates first. Next, could you tell me which operating system you're using? If it's Windows 10 or 11, what specific version are you running? Also, do you experience the same problem when using a USB mouse on your laptop?
I have an Acer Aspire 7 (A715-51G-74CX).
I searched for your laptop:

What operating system came with your device? If it wasn't Windows, where did you obtain the installation file for the OS?
Thank you for the welcome — it’s appreciated!
I’m using Windows 11, version 23H2, and everything is up to date. The laptop was pre-installed with Windows 11 Home from Acer, so I didn’t modify the system or install anything extra.
I haven’t used a USB mouse much, but during the brief time I did, there was no noticeable lag, which suggests the problem might be with the built-in ELAN touchpad.
I haven’t updated the BIOS yet, but I’ll look into Acer’s support page for any available updates. Would you think it’s worth updating even if the changelog doesn’t mention touchpad or input improvements?
Thank you for your continued support with the positive responses thus far. I’m still working through this and truly value your assistance.
Regarding the BIOS, it’s already at version 1.55, and Windows is up to 24H2, but the touchpad problem reappeared after startup. I’ve installed the newest ELAN driver and turned off power-saving settings, yet the issue persists. I’m open to any additional tips that might help!
