Aspire Timeline 5810T. More than 8 hours battery life (All Day Computing), ultra-light weight and sophisticated design, all at the right price. This is the Aspire Timeline. With the Aspire Timeline series, Acer has taken a big, if not the biggest step forward in the concept of mobility, an area where finding the perfect equilibrium between light weight and autonomy has always been the number one priority. The Aspire Timeline series was conceived around the duration of the battery and introduces an entirely new way to render the system lighter, more efficient and less harmful to the environment. From now on you can turn on your Aspire Timeline in the morning and turn it off in the evening without ever having to charge it! Light as your time can be!
