Quick Tips
Reset button (located on the bottom of your Ultrabook)
The Reset button should only be used if your Ultrabook cannot be
powered-off with the Power Button.
• Detach the AC Adapter (if being used).
• Press the Reset button, for several seconds, using a paper clip or
a similar tool.
• You must reconnect the AC adapter prior to powering on your
computer after pressing the Reset button, otherwise your
Ultrabook will not power on.
optimizing Battery life
It takes approximately 3 hours to charge a battery if the Ultrabook
is turned off or is in suspended mode. In battery mode the
processor runs at half speed to conserve battery life. CPU speed
will change depending on the load. Selecting the ECO button will
also save battery life.
• Set power management setting to maximize your battery life
• Adjust display brightness levels to lowest comfortable setting
• Utilize Suspend mode when not using your Ultrabook
• Turn off Wireless LAN when not in use
• Close unused programs
• Remove unused USB powered devices
• Read the Power Management section in your User's Guide for
additional features
Heat damage to your lithium ion battery
Extended exposure to heat will have a negative impact on your
battery. Do not expose your Ultrabook to excessive heat such as
leaving it in the car on a hot summer day.
Discharging your battery
Full battery discharges (to unit shutdown or 0%) should be
avoided. It is recommended that batteries only be partially
discharged to levels of 20~30% before recharging.
Prolonged storage
If your Ultrabook isn't going to be used for a while, you should
remove its Lithium ion battery. To store a battery for long periods
of time, its charge capacity should be around 40% and store it in a
cool dry place.

• Fn + F6 to decrease brightness
• Fn + F7 to increase brightness
Batteries subjected to shocks, vibration or extreme temperatures can be
