Power Management Continued
Storing a Battery Pack
CAUTION:  to prevent damage to a battery pack, do not expose it to high temperatu\
res for extended periods
of time.
If the computer will be unused and unplugged from an external power sour\
ce for more than two weeks, remove and store 
the battery packs.
Maximizing Battery Pack Life
Battery pack operating time varies depending on the system components, o\
ptions, and applications used. Battery operating 
time can increase by as much as 50% by controlling the energy used by th\
e computer and the energy stored in the battery 
pack. 
To maximize battery pack life, use the following guidelines:
Initiate Suspend or Hibernation or turn the computer off when you are no\
t using it.
l   
Reduce the display brightness and select a shorter screen save timeout.l   
Keep a battery pack in the computer when you are using the computer with\
 external power.l   
Disconnect external equipment that does not have its own power source (\
external equipment connected to the 
computer drains the battery pack).l   
Exit modem programs when you are not using them.l   
Remove a PC Card when you are not using it.l   
When storing the computer for more than two weeks, remove battery packs \
and store them separately to reduce the 
discharge rate and increase battery life.l   
Store the battery pack in a cool, dry place when it is not in use. High \
temperatures cause a battery pack to lose its 
charge more quickly and reduce battery pack life.l   
Format diskettes while using external power when possible (formatting d\
iskettes increases the drain on a battery 
pack).l   
System Beeps
Beeps with a Blinking Battery Charge Light
When the computer beeps while the battery charge light is blinking, the \
computer has entered a low battery condition.
CAUTION:   When you are alerted of a low battery condition, very little bat\
tery charge remains. Save your
information and take immediate action to resolve the low battery conditi\
on.
Selecting a Power Source
NOTE: If your external monitor is not 
Energy Star L compliant, enabling monitor energy-saving features may cause
video distortion when the screen save timeout occurs.
Resolving Low-Battery Conditions
If external power is available, do one of the following:
Connect the computer to an electrical outlet with the AC adapter.
l   
Dock the computer in a docking base that is connected to external power.\
l   
Plug an optional automobile power adapter/charger into the power connect\
or on the computer and into a vehiclel    
						

							cigarette lighter receptacle.
Plug an optional aircraft power adapter into the power connector on the \
computer and into the in-seat power supply 
available on some commercial aircraft. 
An optional aircraft power adapter can be used to run the computer, but \
cannot be used to charge a battery pack. 
If a charged battery pack is available, press the suspend button to initiate Suspend (standby), then remove the discharged
battery pack and insert a charged battery pack. 
If neither external power nor a charged battery pack is available, press\
  Fn + the  suspend  button to initiate Hibernation.
or 
Save your work, then shut down the computer.
Restoring from Hibernation after Resolving a Critical Low-Battery Condition
Slide the power switch. If the computer does not have enough power to re\
store your work: Press  Ctrl+Alt +Del  to abort the restoration.
1.  
Insert a charged battery pack or connect the computer to external power.\
2.  
Slide the power switch.3.  
Charging a Battery Pack
A battery pack can be recharged wherever external power is available.
NOTE: Charging may be delayed if a battery pack is new, has not been used for \
2 weeks or more, or is much warmer or 
cooler than a comfortable room temperature.
To increase the accuracy of all battery charge displays: Allow a battery pack to discharge to the low-battery level through norma\
l use before charging it.
l   
When you charge a battery pack, charge it fully.l   
Before charging a new battery pack or a battery pack that has not been u\
sed for two weeks or more, calibrate the 
new battery pack or check the calibration on the unused battery pack.l   
Monitoring the Charge in a Battery Pack
Using the Battery Status Tab
To access the Battery Status tab, press the  Fn+F8  hotkeys or select  Start-> Setting -> Control  Panel  power icon
(named Power, Power Management, or Compaq Power, depending on your oper\
ating system), 
then select the  Battery Status  tab.
To display the location of a listed battery, select the corresponding ba\
ttery icon. A lightening bolt icon beside a battery icon 
indicates that the battery pack in that location is charging.
Using the Battery Meter or Power Meter Icon
The battery meter icon, called the power meter icon in Windows 98, chang\
es shape to indicate whether the computer is 
running on external power or on a full, half-full, or nearly discharged \
battery pack. 
To display the battery meter icon in the taskbar, select  Start-> Settings-> Control Panel-> Power  Management->
Power  Meter  tab, then select the  Show Power Meter  on the  Taskbar  check box.
Using the Power or Power Meter Tab
To access the tab select  Start-> Settings -> Control  Panel-> Power  Management-> Power  Meter tab.
To view the combined percent of total power remaining in all battery pac\
ks in the system, clear the  Show the Status
of All Batteries  check box.
l   
To view the percent of total power remaining in each battery pack in the\
 system, select the  Show the  Status  of All
Batteries  check box.l   
Calibrating a Battery Pack
Calibration increases the accuracy of all battery charge displays. The c\
alibration utility supports all battery packs that can be 
used in the computer. Use the calibration utility both to check the cali\
bration of a battery pack and to calibrate or 
recalibrate a battery pack. A battery pack cannot be calibrated unless t\
he utility reports that it needs calibration. 
The following is a list of important information concerning the calibrat\
ion of a battery pack: 
						

							A new battery pack can be charged, then used to run the computer before \
the battery pack is calibrated. However, 
the amount of charge in the new battery pack cannot be reported accurate\
ly until the new battery pack has been 
calibrated.l   
Check the calibration of a used battery pack periodically and whenever b\
attery charge displays seem inaccurate.l   
While a battery pack is being calibrated, it is fully charged, then full\
y discharged.l   
A battery calibration icon in the taskbar displays an Up arrow during th\
e charge phase and a Down arrow during the 
discharge phase.l   
A calibration cannot resume if the calibration is stopped or if the comp\
uter is shut down during a calibration. An 
interrupted calibration must be restarted.l   
After calibration, a battery pack must be charged before it can be used \
to run the computer.l   
The calibration utility calibrates one battery pack at a time and can ru\
n in the background as you use the computer or 
overnight.l   
Running a Calibration
CAUTION:  To prevent loss of work, ensure that the computer remains connec\
ted to AC power throughout a
calibration.
To run a calibration of your battery pack, complete the following steps:\
If you are checking the calibration of a battery pack, insert the correc\
t battery pack into the Primary Battery Bay or 
MultiBay.
l   
Then connect the computer to external power with the AC adapter or dock \
the computer in a docking base that is 
connected to external power.l   
Access the Battery Calibration tab by selecting  Start-> Settings-> Control Panel-> Power  Management->
Battery  Calibration  tab.l   
View the calibration reports in the Status column. The battery numbers i\
n the Battery column correspond to the 
following locations:l   
Battery NumberBattery Pack Location
1Primary Bay
2MultiBay
In the Status column, select any location number with the “ Needs calibration ” indication beside it.l   
Select the Start Calibration  button.l   
Stopping a Calibration
Select the Stop Calibration button on the Battery Calibration tab. The S\
top Calibration button is visible only during a 
calibration.

Electrostatic Discharge
A sudden discharge of static electricity from a finger or other conducto\
r can destroy 
static-sensitive devices or microcircuitry. Often the spark is neither f\
elt nor heard, but damage 
occurs. An electronic device exposed to electrostatic discharge (ESD) \
may not be affected at all 
and will work perfectly throughout a normal cycle. Although, it may func\
tion normally for a 
while, then degrade in the internal layers, reducing its life expectancy\
. 
Networks built into many integrated circuits provide some protection, bu\
t in many cases, the 
discharge contains enough power to alter device parameters or melt silic\
on junctions.
Generating Static
The table shows how different activities generate static electricity and\
 at different electrostatic 
voltage levels.
