Power Management
The Intel Atom platform has a specified maximum TDP of 11.8 W. Individual figures are 2.5 W for the N270 processor, 6 W for the 945GSE chipset and 3.3 W for the 82801GBM I/O controller. The AUO B089AW01 LCD panel is rated at a maximum power consumption of 3 W. Typical read–write power consumption for the SSD is around 0.3 W, and 0.01 W when idle. The different HDDs are rated at about 1.5–2.5 W for read–write operations and around 0.7 W when idle.
The official ratings for the battery are up to 3 hours for the three cell, and up to 7 hours for the six cell. Linpus Linux Lite has been optimized by Acer for lower power consumption. Battery life is shorter on HDD configurations with Windows XP, at approximately 2.5 hours for the three cell. Although the standard three cell battery is 2.2 Ah, some users have reported 2.4 Ah and 2.9 Ah batteries from the factory. Various suppliers online now carry aftermarket batteries, including the six cell. Aftermarket nine cell batteries are available though they are quite heavy, and also protrude out of the back, reducing the aesthetics but improving airflow.

“The care of a house, the conduct of a home, the management of children, the instruction and government of servants, are as deserving of scientific treatment and scientific professors and lectureships as are the care of farms, the management of manure and crops, and the raising and care of stock.”
