Can anyone help me, please?
[Edited the thread to add the issue detail]
Updating BIOS is risky, if it's necessary only you have to update BIOS with care, go to Acer Support site and download the latest version and install.
Fully charge the battery and connect the laptop always to the mains during the update process.
Do not press any button or switch off the laptop during the update, in fact, you shouldn't touch any keys on the laptop.
Disconnect any USB disks or external HDD and Printers.
Update at your own risk after downloading from here:Support | Acer United States
