Hello Acer,
I'm suffering from the above same touch pad issue. On Advanced mode of bios touch pad not working. But in Basic mode it works fine. BUT THE WORST THING IS TOUCH PAD MODE CHANGES TO ADVANCED MODE WITHOUT MY KNOWLEDGE OR WITHOUT MY INTERFERENCE. And further when that happens even I can't switch on my laptop. My laptop sometimes switch on after 10 minutes I pressed the power button. So my question is whether the touch pad issue makes my laptop not to switch on or not. My laptop is Acer aspire E5-575G.
Should say i wasted lot of money for repairing this up to now. But the issue is still the same.
