Standby and Hibernation Functions

The standby or hibernation function allows you to shut off the computer without closing programs and documents. You can quickly return to the programs and documents that you were working on before standby or hibernation.

Function Data is saved to Recovery time Power supply

Standby Memory Short Required. (If power is not supplied, all data will be lost.)

Hibernation Hard disk Rather long Not required. (However power is slightly consumed to

keep the hibernation.)

Setting Standby or Hibernation

NOTE

z You do not need to make the setting if you use the Windows menu to enter standby or hibernation.

Precautions

z Connect the AC adaptor if the computer will be in standby mode for a long period of time. If you cannot use the AC adap-

tor, use hibernation instead.

z Using standby or hibernation repeatedly may cause malfunction of the computer. To stabilize computer operation, restart

Windows regularly (about once a week) without using standby or hibernation.

z Save the necessary data. z Close files you have opened from removable disk and network drive. z The password you set in the Setup Utility is not requested at resuming. You can use the Windows password for security in

standby or hibernation.

A Click [start] - [Control Panel] - [User Accounts], and select the account. B Click [Create a password] and set the password. C Click [start] - [Control Panel] - [Performance and Maintenance] - [Power Options] - [Advanced], and add the

check mark in [Prompt for password when computer resumes from standby].

Standby and Hibernation Functions

z Do not enter standby or hibernation in the following conditions, otherwise the data or file may be corrupted, standby or

hibernation may not work, or malfunction may occur in the computer or the peripheral devices.

• When the hard disk drive indicator or the SD Memory Card indicator is on.

• When playing/recording audio files or displaying motion video such as MPEG files.

• When writing to a disk.

• When using communication software or network function.

• When using a PC Card. (If the card fails to work normally, restart the computer.)

• When an external mouse is connected to the serial port.

z The computer does not enter standby or hibernation immediately after resuming. Wait approximately one minute.

High temperature mode

The high temperature mode can prevent the battery from deteriorating when the computer is used in high-temperature environment or used for a long time with its battery fully charged. Select [Auto] (default) or [High Temperature] in [Environment] of the [Main] menu of the Setup Utility (Î page 67).

NOTE

z Note that a level corresponding to a 100% charge for high temperature mode is approximately equivalent to an 80%

charge level for normal temperature mode.

z After switching from [Normal Temperature] to [High Temperature] or vice versa, the remaining battery capacity will not

be displayed correctly until the battery pack is completely discharged or fully charged.

z In the [Auto] mode:

Once the computer has automatically switched from the normal temperature mode to the high temperature mode, the computer will not switch back to the normal temperature mode until the battery has been used and recharged to a total charge level of about five times as much as that of the fully-charged state. This is to avoid battery deterioration.

Correcting the Battery Display (Battery Recalibration)

The “Battery Recalibration” function measures and memorizes the battery capacity. To correct the battery display, use this function to fill the battery and then discharge it completely. Perform the procedure at least once immediately after purchasing the computer. Normally the interval of battery recalibration is three months. The battery display may not be correct when the battery pack deteriorates after a long time use. In this case, perform the procedure again.

1 Connect the AC adaptor.

2 Close all the applications.

3 Perform “Battery Recalibration”.

A Click [start] - [All Programs] - [Panasonic] - [Battery] - [Battery Recalibration]. B When the confirmation message appears, click [Start].

recalibration is performed at the shorter interval than approximately a month. In this case, cancel the battery recalibration.

C When the message requests shut down of Windows, click [Yes].

The battery recalibration starts. After the battery pack is fully charged, discharging starts. When the discharging is completed, the power goes off automatically.

After the battery recalibration is finished, normal charging starts.
