Power System

Using AC Power

The Notebook PC power is comprised of two parts, the power adapter and the battery power system. The power adapter converts AC power from a wall

outlet to the DC power required by the Notebook

PC. Your Notebook PC comes with a universal

AC-DC adapter. That means that you may connect

the power cord to any 100V-120V as well as 220V240V outlets without setting switches or using

power converters. Different countries may require

that an adapter be used to connect the provided US-standard AC power cord to a different standard. Most hotels will provide universal outlets to support different power cords as well as voltages. It is always best to ask an experienced traveler about AC outlet voltages when bringing power adapters to another country.

TIP: You can buy travel kits for the Notebook PC that includes power and modem adapters for almost every country.

With the AC power cord connected to the AC-DC converter, connect the AC power cord to an AC outlet (preferably with surge-protection) and then connect the DC plug to the Notebook PC. Connecting the AC-DC adapter to the AC outlet rst allows you to test the AC outlet’s power and the AC-DC converter itself for compatibility problems before connecting the DC power to the Notebook PC. The power indi-

cator on the adapter (if available) will light if the power is within accepted ranges.

IMPORTANT! Damage may occur if you use a different adapter to power the Notebook PC or use the Notebook PC’s adapter to power other electrical devices. If there is smoke, burning scent, or extreme heat coming from the AC-DC adapter, seek servicing. Seek servicing if you suspect a faulty AC-DC adapter. You may damage both your battery pack(s) and the Notebook PC with a faulty AC-DC adapter.

NOTE: This Notebook PC may come with either a two or three-prong plug depending on territory. If a three-prong plug is provided, you must use a grounded AC outlet or use a properly grounded adapter to ensure safe operation of the Notebook PC.

WARNING! THE POWER ADAPTER MAY BECOME WARM TO HOT WHEN IN USE. BE SURE NOT TO COVER THE ADAPTER AND KEEP IT AWAY FROM YOUR BODY.

Using Battery Power

The Notebook PC is designed to work with a removable battery pack. The battery pack consists of a set of battery cells housed together. A fully charged pack will provide several hours of battery life, which can be further extended by using power management features through the BIOS setup. Additional battery packs are optional and can be purchased separately through a Notebook PC retailer.

Installing and Removing the Battery Pack

Your Notebook PC may or may not have its battery pack installed. If your Notebook PC does not have its battery pack installed, use the following procedures to install the battery pack.

IMPORTANT! Never attempt to remove the battery pack while the Notebook PC is turned ON, as this may result in the loss of working data.

To install the battery pack:

IMPORTANT! Only use battery packs and power adapters supplied with this Notebook

PC or specically approved by the manufacturer or retailer for use with this model or

else damage may occur to the Notebook PC.

To remove the battery pack:

Battery Care

The Notebook PC’s battery pack, like all rechargeable batteries, has a limit on the number times it can

be recharged. The battery pack’s useful life will depend on your environment temperature, humidity, and

how your Notebook PC is used. It is ideal that the battery be used in a temperature range between 5˚C

and 35˚C (41˚F and 95˚F). You must also take into account that the Notebook PC’s internal temperature

is higher than the outside temperature. Any temperatures above or below this range will shorten the life

of the battery. But in any case, the battery pack’s usage time will eventually decrease and a new battery

pack must be purchased from an authorized dealer for this Notebook PC. Because batteries also have a

shelf life, it is not recommended to buy extras for storing.

WARNING! For safety reasons, DO NOT throw the battery in re, DO NOT

short circuit the contacts, and DO NOT disassemble the battery. If there is any abnormal operation or damage to the battery pack caused by impact, turn OFF the Notebook PC and contact an authorized service center.

25

3 Getting Started

Powering ON the Notebook PC

The Notebook PC’s power-ON message appears on the screen when you turn it ON. If necessary, you may adjust the brightness by using the hot keys. If you need to run the BIOS Setup to set or modify the

system conguration, press [F2] upon bootup to enter the BIOS Setup. If you press [Tab] during the splash screen, standard boot information such as the BIOS version can be seen. Press [ESC] and you will

be presented with a boot menu with selections to boot from your available drives.

NOTE: Before bootup, the display panel ashes when the power is turned ON. This is

part of the Notebook PC’s test routine and is not a problem with the display.

IMPORTANT! To protect the hard disk drive, always wait at least 5 seconds after turning OFF your Notebook PC before turning it back ON.

WARNING! DO NOT carry or cover a Notebook PC that is powered ON with any materials that will reduce air circulation such as a carrying bag.

The Power-On Self Test (POST)

When you turn ON the Notebook PC, it will rst run through a series of software-controlled diagnostic tests called the Power-On Self Test (POST). The software that controls the POST is installed as a permanent part of the Notebook PC’s architecture. The POST includes a record of the Notebook PC’s

hardware conguration, which is used to make a diagnostic check of the system. This record is created

by using the BIOS Setup program. If the POST discovers a difference between the record and the exist-

ing hardware, it will display a message on the screen prompting you to correct the conict by running

BIOS Setup. In most cases the record should be correct when you receive the Notebook PC. When the

test is nished, you may get a message reporting “No operating system found” if the hard disk was not

preloaded with an operating system. This indicates that the hard disk is correctly detected and ready for the installation of a new operating system.

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 Start > 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.

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.

26

Getting Started 3

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 gure 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.

Note: Screen captures shown here are examples only and

may not reect what you see

in your system.

Right-click the battery icon

Cursor over the battery icon without power adapter�

Left-click the battery icon

NOTE: 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).

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

Cursor over the battery icon with power adapter�

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 rst 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.

NOTE: The battery stops charging if the temperature is too high or the battery voltage is too high.

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.
