IMPORTANT! If warnings are still given during bootup after 
running a software disk checking utility, you should take your 
Notebook PC in for servicing. Continued use may result in data 
loss. 
Self Monitoring and Reporting Technology
The S.M.A.R.T. (Self Monitoring 
and Reporting Technology) 
checks the hard disk drive during 
POST and gives a warning 
message if the hard disk drive 
requires servicing. If any critical 
hard disk drive warning is 
given during bootup, backup 
your data immediately and run 
Windows disk checking program. 
To run Window’s disk checking 
program: click Windows > 
select Computer > right-click 
a hard disk drive icon > choose 
Properties > click the Tools tab > 
click Check Now > click Start. You can also select “Scan ... sectors” for 
more effective scan and repair but the process will run slower.

You will be warned when battery power is low. If you continue 
to ignore the low battery warnings, the Notebook PC eventually 
enters suspend mode ( Windows default uses STR).
Screen captures shown here are examples only and may not 
reflect what you see in your system. 
Checking Battery Power
The battery system implements the Smart Battery standard under 
the Windows environment, which allows the battery to accurately 
report the amount of charge left in the battery. A fully-charged 
battery pack provides the Notebook PC a few hours of working 
power. But the actual figure varies depending on how you use the 
power saving features, your general work habits, the CPU, system 
memory size, and the size of the display panel.

WARNING!  Suspend-to-RAM (STR) does not last long when the 
battery power is depleted. STR is not the same as power OFF. 
STR requires a small amount of power and will fail and lose data 
if no power is available due to complete battery depletion or 
no power supply (e.g. removing both the power adapter and 
battery pack).

WARNING!  DO NOT leave the battery pack discharged. The 
battery pack will discharge over time. If not using a battery pack, 
it must continued to be charged every three months to extend 
recovery capacity or else it may fail to charge in the future. 
The battery stops charging if the temperature is too high or the 
battery voltage is too high.
Charging the Battery Pack
Before you use your Notebook PC on the road, you will have to 
charge the battery pack. The battery pack begins to charge as 
soon as the Notebook PC is connected to external power using the 
power adapter. Fully charge the battery pack before using it for the 
first time. A new battery pack must completely charge before the 
Notebook PC is disconnected from external power. It takes a few 
hours to fully charge the battery when the Notebook PC is turned 
OFF and may take twice the time when the Notebook PC is turned 
ON. The battery status indicator on the Notebook PC turns OFF when 
the battery pack is charged.
The battery starts charging when the charge remaining in 
the battery drops below 95%. This prevents the battery from 
charging frequently. Minimizing the recharge cycles helps 
prolong battery life.

IMPORTANT!  To protect the hard drive, wait at least 5 seconds 
after turning OFF your Notebook PC before turning it back ON. 
Power Options
The power switch turns ON and 
OFF the Notebook PC or putting 
the Notebook PC into sleep 
or hibernation modes. Actual 
behavior of the power switch 
can be customized in Windows 
Control Panel “Power Options.” 
For other options, such as “Switch 
User, Restart, Sleep, or Shut Down,” click the arrowhead next to the 
lock icon.
Restarting or Rebooting
After making changes to your operating system, you may be 
prompted to restart the system. Some installation processes will 
provide a dialog box to allow restart. To restart the system manually, 
choose Restart.

Emergency Shutdown
In case your operating system cannot properly turn OFF or restart, 
there is an additional way to shutdown your Notebook PC:
Hold the power button  over 4 
seconds.
IMPORTANT!  DO NOT use emergency shutdown while data is 
being written; doing so can result in loss or destruction of your 
data.

Sleep and Hibernate
Power management settings 
can be found in the Windows 
> Control Panel > Hardware 
and Sound > Power Options. In 
Power Options, you can define 
Sleep/Hibernate or Shut Down 
for closing the display panel or 
pressing the power button. Sleep 
and Hibernate saves power when your Notebook PC is not in use 
by turning OFF certain components. When you resume your work, 
your last status (such as a document scrolled down half way or email 
typed half way) will reappear as if you never left. Shut Down will 
close all applications and ask if you want to save your work if any are 
not saved.
Power Management Modes
The Notebook PC has a number of automatic or adjustable power 
saving features that you can use to maximize battery life and lower 
Total Cost of Ownership ( TCO). You can control some of these 
features through the Power menu in the BIOS Setup. ACPI power 
management settings are made through the operating system. 
The power management features are designed to save as much 
electricity as possible by putting components into a low power 
consumption mode as often as possible but also allow full operation 
on demand. 
						

							
Notebook PC User Manual37

Sleep is the same as Suspend-to-
RAM (STR). This function stores 
your current data and status in 
RAM while many components 
are turned OFF. Because RAM 
is volatile, it requires power to 
keep (refresh) the data. Click 
the Windows button and the 
arrowhead next to the lock icon 
to see this option. You can also use the keyboard shortcut [Fn F1] 
to activate this mode. Recover by pressing any keyboard key except 
[Fn]. (NOTE: The power indicator will blink in this mode.)
Hibernate is the same as Suspend-to-Disk (STD) and stores your 
current data and status on the hard disk drive. By doing this, RAM 
does not have to be periodically refreshed and power consumption 
is greatly reduced but not completely eliminated because certain 
wake-up components like LAN needs to remain powered. Hibernate 
saves more power compared to Sleep. Click the Windows button 
and the arrowhead next to the lock icon to see this option. Recover 
by pressing the power button. (NOTE: The power indicator will be 
OFF in this mode.)

Thermal Power Control
There are three power control methods for controlling the Notebook 
PC’s thermal state. These power control cannot be configured by 
the user and should be known in case the Notebook PC should 
enter these states. The following temperatures represent the chassis 
temperature (not CPU).
•	 The	fan	turns	ON	for	active	cooling	when	the	temperature	reaches	the	safe	upper	limit.
•	 The	CPU	decreases	speed	for	passive	cooling	when	the	temperature	 exceeds	the	safe	upper	limit.
•	 The	system	shut	down	for	critical	cooling	when	temperature	ex
-
ceeds	the	maximum	safe	upper	limit.
