I recently upgraded the OS on my Laptop from windows 8 to windows 10 Pro. after the installation everything is perfectly except mouse pad. I used Fn + F7 keys it did not work. I then opened BIOS to my surprise i could not see Mouse-Pad options there. I also tried to go for BIOS update but i still could not see Acer Aspire E15 E5-571-38AZ model on Acer website.
Now, i am not sure if i download any BIOS update for another model what will happen?
