Here it's important to check for compliance with APM (Advanced Power Management) and ACPI (Advanced Control and Power Interface). The energy management function co-developed by Toshiba and supported by modern Microsoft operating systems such as Windows MEŽ allows individual components to be turned off or put in Sleep mode. You should turn off components that are not needed when on the road. Toshiba systems allow you to turn off unused PC Cards (expansion devices in credit card format), making a valuable contribution to extending battery life.

Every Toshiba notebook ships with power management software which allows users to set the period after which the hard disk or display should be turned off. In both cases, a period of 15-20 minutes is recommended, since the hard disk consumes extra power each time it is restarted.

Standby mode
The Standby mode offered by your power management software is a further aid to battery life. In Standby mode, all components are turned off and current data is written to RAM. Only RAM continues to be supplied with power. When you turn on again, the system will return you to exactly the same situation as before you selected Standby. All Toshiba notebooks come with this feature as standard.

Hibernation mode
In Hibernation mode, all current data and current applications are saved to the hard disk, and then the machine itself is turned off. This mode offers greater protection for your data than Standby. Again, Toshiba systems offer this feature as standard, but you will need to check whether your choice of operating system also supports it.

RAM saves power
Strange though it may seem, having a generous amount of RAM actually reduces power consumption. This is because more RAM means the hard disk is accessed less often. An additional benefit is significantly higher system performance, since accessing RAM is much faster than retrieving data from the hard disk.
