Our school board have over 800 units of Acer Chromebook through our 20 Schools. Since 2 months, nearly 300 Acer Chromebook C740, had previously purchased in March 2015 ( out of warranty) have stopped working because of Swollen battery. Some of these chromebook have deformation which causes trackpad issues.
From what I can see on this community, this is a commum problem. Acer have a battery replacement program?
