Hardware Problem - Battery
Battery maintenance.
1. Register the Notebook PC for a one-year-warranty using the following website:
http://member.asus.com/login.aspx?SLanguage=en-us
2. Do NOT remove the battery pack while using the Notebook PC with the AC adaptor to prevent
damage caused by the accidental power loss. The ASUS battery pack has protection circuitry to
prevent over-charging so it will not damage the battery pack if it is left in the Notebook PC.
3. Store the battery pack in a dry location with temperatures between 10℃ and 30℃ if you will not
be using it for a long time. It is strongly recommended that you charge the battery pack every three
months.
