    First, which BIOS version are you running? The last BIOS is the Version: 1.21 dated: 2020/07/28 update BIOS to the latest with the executable file "ZAW_121.exe" but be very careful and turn off your anti virus, anti malware and don't run any programs and make sure that your laptop is plugged into the mains and there is no power interruptions while the BIOS is updating as "Upgrading your system BIOS incorrectly could harm your Acer product. Please proceed with caution" and after that it should fix your problems, you must be running an old BIOS.
