Thesedevices may fail to operate, you will then need to restart your computer using thekeyboard.Do not enter either the standby or hibernation mode during the following periods (youmay corrupt your data or file):• While the MP indicator ( )* or hard disk drive indicator ( ) is on.* Except when using a second battery pack• While playing/recording audio files and playing an MPEG file.• While communications software is being used.Do not enter either the standby or hibernation mode during the following periods.The standby or hibernation function may not work, or the computer (or peripherals)may fail to work properly.• When a file in an external device such as a CD drive, external hard disk, or ATA cardis opened, the standby or hibernation function may not work. In such cases, closethe file.• LAN cards (ports), SCSI cards and modem cards (port) etc. may not recover afterentering the standby or hibernation mode. If this occurs, restart the computer.Windows 98 Windows 2000• When a USB device is in use or is connected to the computer (note: only for someUSB devices). A USB device may have to be removed temporarily and the com-puter restarted in cases where the computer is unable to start up properly.Do not enter either the standby or hibernation mode when using an operating systemother than the one that comes with your computer, the Setup Utility, or when experi-encing static electricity or noise.Do not install or remove peripherals while your computer is in the standby or hiberna-tion mode; abnormal operation may result.If you hold down on Alt , Ctrl or Shift to enter either the standby or hibernationmode, after resuming operation, you must press the same key. For example, if you holddown on Shift while sliding the power switch, upon resuming, if you do not pressShift again, only capital letters will result from typing.Rotate the power switch and hold it for more than four seconds to power off thecomputer only when the computer locks up. Data not previously saved will be lost.In the standby mode, power is consumed. If PC Cards are inserted, more of thatpower is consumed. When all power has been consumed, all data saved at standbyis lost since it is retained in memory. We therefore recommend plugging in the ACadaptor when using the standby function.If the standby or hibernation function is used repeatedly, the computer may not workproperly. To stabilize computer operations, we recommend shutting down Windows([Start] - [Shut Down]) on a regular basis (about once a week) without using thestandby or hibernation function.The screen that is displayed when resuming from the hibernation mode may be dif-ferent from the screen that is displayed before entering the hibernation mode.(To next page)
