BIOS 1.12 improves AC adapter power continuity

Why does my ConceptD notebook beep and temporarily switch to battery power when I move the AC adapter?

Impacted models:

CC715-71

CC715-71P

CC715-91P

If you experience your ConceptD notebook beeping or temporarily switching from AC to battery power, you should update to BIOS 1.12 to resolve this issue. BIOS 1.12 will help improve AC adapter power continuity and is posted on the Acer Drivers and Manuals page.
