Dear valued Acer Customer,
Acer has identified a potential issue with certain units of the following notebook models:
1. Aspire 5738 (AS5738G)
2. Aspire 5738Z (AS5838ZG)
Under certain circumstances the power adapter on the affected units may overheat and present risk of burn to the user. The cause of this issue is due to the installation of an incorrect BIOS firmware. Fortunately, owners of the affected units may remedy this issue by simply downloading and installing an updated version of the BIOS.
