|3.1.1.5 Knowing the Amount of Power
|While operating the computer, you can monitor the amount of remaining
|battery power on the system status display panel. If the computer detects
|a battery-low condition, the icon PICTURE 60 starts blinking after three
|beeps to indicate that it is time to charge the Rechargeable Battery. For
|information on how to charge the Rechargeable Battery, see page 3.1.2.
|Warning: This blinking icon PICTURE 61 indicates that the Rechargeable
|Battery urgently needs charging and that less than 3% of the full power of
|the battery remains. The computer will enter suspend or partial suspend
|mode in approximately 1 minute to preserve data. Do not leave the
|computer in this condition for more than 1 hour as this can shorten the
|life span of the battery. For more information, see page 2.5.
|+--- For Your Convenience (Spare Rechargeable Battery) ------------------+
¦ ¦
¦ ¦
|¦ Usually, a complete charge makes it possible to use the battery for up ¦
|¦ to 3 hours depending on applications and the configuration. However, ¦
|¦ a fully-charged battery gradually loses its charge if not used for a ¦
|¦ month or so. In this condition, the battery does not reach full ¦
|¦ charge by charging it only once. ¦
¦ ¦
|¦ It is recommended that you obtain a spare Rechargeable Battery so you ¦
|¦ can immediately replace the Rechargeable Battery with the low charge ¦
|¦ and continue your work without delay. The low battery can be replaced ¦
|¦ without losing data or saving an application. The low battery can be ¦
|¦ recharged later when you are not operating the computer. See page ¦
|¦ 3.1.2. ¦

3.5 Suspend and Resume Modes
The Model L40 SX is a battery-powered computer with unique techniques to
conserve battery power. For example, if the display is closed while
#operating the computer, it automatically enters suspend mode and all tasks
#are stopped to save power; the present state is stored in the computer
#memory. Later, when the display is opened, the computer automatically
#returns to resume mode and restores to the same state as when it entered
#suspend mode.
|The following figure shows what causes the computer to enter suspend mode
|and return to resume mode.

|3.5.1.2 Partial Suspend Mode
|Some application software interferes with the power management capability
|of the computer and prevents it from entering full suspend mode. If this
|happens, the computer beeps twice because it is entering partial suspend
|mode. To resume, open the display as with full suspend mode.
@Power management device drivers programs for some operating systems or
@applications are available on the Reference Diskette. Installing these
@drivers before entering suspend mode eliminates the application software
@interference. This allows the L40 SX, when entering suspend mode, to
@enter full suspend mode. To install those programs, see Appendix D,
@"Customizing Software" in topic D.0.

|1. Power Saving Less in Partial Suspend Mode
@ Avoid leaving the computer in partial suspend mode for an extended
@ period. More power is expended in partial suspend mode than in full
@ suspend mode.
| Warning: If you need to exchange batteries during partial suspend
| mode, first connect the AC Adapter or the Car Battery Adapter, then
| make the battery exchange.
|2. Battery Exchange
| To replace a discharged Rechargeable Battery with a charged one, close
| the display to put the computer in suspend mode, wait 10 seconds after
| the one beep, replace the battery within 1 minute, and then open the
| display to resume operation. If the computer has been in suspend mode
| because of the low battery power, no beep sounds even though the
| display is closed.
| Warning: If you need to exchange batteries during partial suspend
| mode, first connect the AC Adapter or the Car Battery Adapter, then
| make the battery exchange.
|3. Pointing Devices
| Pointing devices are movement-sensitive. You cannot operate or move
| them during two short periods of time. The following shows the
| periods.

4.0 Solving Computer Problems
Problems with your computer can be caused by software, hardware, or both.
You can test the hardware yourself using computer internal self-tests and
the testing programs on the backup copy of the Reference Diskette. If a
hardware problem occurs during this testing, an error message appears with
the cause of the problem and the action to take.
By using the Reference Diskette, the Troubleshooting Charts, and the other
information in this section, you should be able to solve the problem
yourself or obtain a considerable amount of information about the problem.
Always use the backup copy of the Reference Diskette. The backup copy
should contain your computer's current configuration information and
testing programs.
