The BIOS is dated 2015, and Acer is not renowned for producing updated BIOS.
The problem here is almost certainly that the machine shipped with Windows 8 Core edition installed - or no Windows at all.
As such it has no SLIC table to be able to activate the OEM_SLP Key in use.
Is there a COA sticker for Windows 7 on the case?
Is there a Windows 8 sticker - or a Windows 8 Pro sticker on the case?
