This computer is equipped with the Toshiba eco power plan. 
Operating the computer with this power plan enabled reduces 
electrical power consumption by slightly lowering system 
performance. For example, when this power plan is enabled, the 
brightness of the display is reduced and the interval before Sleep 
mode takes effect is shortened. To enable or disable the eco power 
plan, see 

The Toshiba eco Utility™ monitors your power savings from using 
the eco power plan by tracking real-time power consumption and 
accumulated savings over time. To learn how to access the utility, 
see

For more information on the Toshiba eco power plan, see the Help 
file in the TOSHIBA eco Utility™ window.

When your main battery has run out of power, you have two 
options: plug in the AC adaptor or install a charged main battery.

Never short circuit the battery pack by either accidentally or 
intentionally bringing the battery terminals in contact with another 
conductive object. This could cause serious injury or fire, and could 
also damage the battery pack and computer.

❖

Never expose a battery pack to abnormal shock, vibration or 
pressure. The battery pack's internal protective device could fail, 
causing it to overheat or ignite, resulting in caustic liquid 
leakage, or explosion or fire, possibly resulting in death or 
serious injury.

then either completely shut down your computer or put it into 
Hibernation mode before changing the main battery.
