Chapter 7: Troubleshooting And Tips

Resetting The NETBOOK PRO

•Recharge the main battery. If you continue to use the NETBOOK PRO when the main battery is low, it will eventually not have enough power and the NETBOOK PRO will switch off. You will not be able to switch it on again until you reconnect the AC power to recharge the battery, or replace the main battery with a charged one.

If the NETBOOK PRO doesn't seem to turn off:

•Check the automatic switch off time using the Power icon from the Control Panel. See “Power Management” on page 14.

7.1.4 Resetting The NETBOOK PRO

If you find that you cannot exit a program normally, right-click or alt-tap on the taskbar and select Task Manager from the context menu. Select the task that appears to be unresponsive and click on the End Task button.

Press Alt Tab or Ctrl Alt Delete briefly to bring up the task manager. This is useful when a misbehaving program is monopolizing system resources and slowing the system.

Note: If you hold Ctrl Alt Delete for more than 3 seconds, the NETBOOK PRO will soft reset.

If this does not work, or if your NETBOOK PRO appears to have “locked up”, you can always perform a “reset”. For instructions, please see “Performing A Soft Reset” on page 31. This should restart your NETBOOK PRO while preserving most of your information.

It is worth trying a reset if the keys on the NETBOOK PRO do not appear to respond, or if the NETBOOK PRO appears to switch on and you are sure that the batteries are good, but the screen is otherwise blank.

7.1.5 Battery Life Of The NETBOOK PRO

Many variables affect NETBOOK PRO power consumption and battery life. Unlike batteries using other chemistries, Lithium Ion batteries do not suddenly fail unless they have been abused in some way. The battery capacity gradually reduces over the lifetime of the battery. Typically, the capacity of a NETBOOK PRO battery pack will decline by approximately 15-20% of initial capacity over 400 charge/discharge cycles. The battery capacity also declines slowly with aging, i.e. in storage.
