Depending on your model, the two power plans eco and Balanced 
are satisfactory for most people and do not need to be edited. The 
eco plan is the best used for maximum battery time. The Balanced 
plan is a compromise between battery time and performance. 

This computer is equipped with the 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 eco Utility

If you find that a new battery is needed, contact the location where 
you purchased the computer for more information on replacing the 
battery. Toshiba will not be responsible for any product damage, 
data loss, service or part replacement made necessary by improper

If the battery is leaking or its case is cracked, put on protective 
gloves to handle it.
