Introduction
============
The FreeType Project is distributed in several archive packages; some of them may contain, in addition to the FreeType font engine, various tools and contributions which rely on, or relate to, the FreeType Project.
This license applies to all files found in such packages, and which do not fall under their own explicit license. The license affects thus the FreeType font engine, the test programs, documentation and makefiles, at the very least.
This license was inspired by the BSD, Artistic, and IJG (Independent JPEG Group) licenses, which all encourage inclusion and use of free software in commercial and freeware products alike. As a consequence, its main points are that:
We don't promise that this software works. However, we will be interested in any kind of bug reports. (`as is' distribution)
You can use this software for whatever you want, in parts or full form, without having to pay us. (`royalty-free' usage)
You may not pretend that you wrote this software. If you use it, or only parts of it, in a program, you must acknowledge somewhere in your documentation that you have used the FreeType code. (`credits')
We specifically permit and encourage the inclusion of this software, with or without modifications, in commercial products.
We disclaim all warranties covering The FreeType Project and assume no liability related to The FreeType Project.
Finally, many people asked us for a preferred form for a credit/disclaimer to use in compliance with this license. We thus encourage you to use the following text:
"""
Portions of this software are copyright (C) <year> The FreeType Project
www.freetype.org

"""
Please replace <year> with the value from the FreeType version you actually use.

ENERGY STAR® Program

Your Computer model may be ENERGY STAR compliant. If the model you purchased is compliant, it will be listed on the following website:
https://www.energystar.gov/productfinder/product/certified­computers
Dynabook is a partner in the ENERGY STAR Program and has designed this computer to meet the latest ENERGY STAR guidelines for energy efficiency. Your computer ships with the power management options preset to a configuration that will provide the most stable operating environment and optimum system performance for both AC power and battery modes.
To conserve energy, your computer is set to enter the low­power Sleep Mode which shuts down the system and display within 15 minutes of inactivity in AC power mode.
Dynabook recommends that you leave this and other energy saving features active, so that your computer will operate at its maximum energy efficiency. You can wake the computer from Sleep Mode by pressing the power button.
Your ENERGY STAR certified computer should be set by default to enter a low-power "sleep mode" after a period of inactivity. Simply touching the mouse or keyboard "wakes" the computer in seconds. These sleep features can save you up to $23 per year (200 kWh per year in electricity) and prevent up to 300 pounds of greenhouse gas emissions annually. To learn how to adjust or activate these sleep settings on your computer, please go to:
www.energystar.gov/sleepinstructions
To activate sleep settings organization-wide quickly and easily through network tools, please go to:

General Precautions

Your computers are designed to optimize safety, minimize strain and withstand the rigors of portability. However, certain precautions should be observed to further reduce the risk of personal injury or damage to the computer.
Be certain to read the following general precautions and to note the cautions included in the text of the manual.

Provide adequate ventilation

Always make sure that your computer and AC adaptor have adequate ventilation and are protected from overheating when the power is turned on or when an AC adaptor is connected to a power outlet (even if your computer is in Sleep Mode). In this condition, observe the following:
Never cover your computer or AC adaptor with any object. Never place your computer or AC adaptor near a heat source, such as
an electric blanket or heater. Never cover or block the air vents including those at the base of the
computer. Always operate your computer on a hard flat surface. Using your
computer on a carpet or other soft material can block the vents. Always provide sufficient space around the computer.
Overheating your computer or AC adaptor could cause system failure, computer or AC adaptor damage or a fire, possibly resulting in serious injury.

Creating a computer-friendly environment

Place the computer on a flat surface that is large enough for the computer and any other items you are using, such as a printer.
Leave enough space around the computer and other equipment to provide adequate ventilation. Otherwise, they might overheat.
To keep your computer in prime operating condition, protect your work area from:
Dust, moisture, and direct sunlight. Equipment that generates a strong electromagnetic field, such as
stereo speakers (other than speakers that are connected to the computer) or speakerphones.
Rapid changes in temperature or humidity and sources of temperature change such as air conditioner vents or heaters.
Extreme heat, cold, or humidity. Liquids and corrosive chemicals.
User's Manual
1-17

Stress injury

Carefully read the Instruction Manual for Safety and Comfort. It contains information on the prevention of stress injuries to your hands and wrists that can be caused by extensive keyboard use. It also includes information on work space design, posture, and lighting that can help reduce physical stress.

Heat injury

Avoid prolonged physical contact with the computer. If the computer is used for long periods, its surface can become very warm. While the temperature will not feel hot to the touch, if you maintain physical contact with the computer for a long time, for example if you rest the computer on your lap or if you keep your hands on the palm rest, your skin might suffer a low-heat injury.
If the computer has been used for a long time, avoid direct contact with the metal plate supporting the various interface ports as this can become hot.
The surface of the AC adaptor can become hot when in use but this condition does not indicate a malfunction. If you need to transport the AC adaptor, disconnect it and let it cool before moving it.
Do not lay the AC adaptor on a material that is sensitive to heat as the material could become damaged.

Pressure or impact damage

Do not apply heavy pressure to the computer or subject it to any form of strong impact as this can damage the computer's components or otherwise cause it to malfunction.

Cleaning the computer

To help ensure long, trouble-free operation, keep the computer free of dust and dirt, and use care with all liquids around it.
Be careful not to spill liquids into the computer. If the computer does get wet, turn the power off immediately and let the computer dry completely. In these circumstances, you should get the computer inspected by an authorized service provider in order to assess the scope of any damage.
Clean the plastics of the computer using a cloth slightly dampened with water.
You can clean the display screen by spraying a small amount of glass cleaner onto a soft, clean cloth and then wiping the screen gently with the cloth.
Never spray cleaner directly onto the computer or let liquid run into any part of it. Never use harsh or caustic chemical products to clean the computer.

Be sure to read the enclosed Instruction Manual for Safety and Comfort for information on the safe and proper use of this computer. It is intended to help you be more comfortable and productive while using a notebook computer. By following the recommendations in it, you can reduce your chance of developing a painful or disabling injury to your hand, arms, shoulders, or neck.
This section provides basic information to start using your computer. It covers the following topics:
Connecting the AC adaptor Opening the display Turning on the power Initial setup Getting to know Windows
Use a virus-check program and make sure that it is updated regularly.
Never format storage media without checking its content - formatting destroys all stored data.
It is a good idea to back up the internal Solid-State Drive or other main storage device to external media periodically. General storage media is not durable or stable over long periods of time and under certain conditions might result in data loss.
User's Manual 2-2
Before you install a device or application, save any data in memory to the internal Solid-State Drive or other storage media. Failure to do so might result in data loss.

Connecting the AC adaptor

Attach the AC adaptor when you want to charge the battery or operate from AC power. The battery pack must be charged before you can operate from battery power.
The AC adaptor can automatically adjust to any voltage ranging from 100 volts to 240 volts and to a frequency of either 50 hertz or 60 hertz, enabling you to use this computer in almost any country/region. The adaptor converts AC power to DC power and reduces the voltage supplied to this computer.
It is recommended to use the AC adaptor that was included with your computer, or use AC adaptors specified by Dynabook to avoid any risk of fire or other damage to the computer. Use of an incompatible AC adaptor might cause fire or damage to the computer possibly resulting in serious injury. Dynabook assumes no liability for any damage caused by use of an incompatible adaptor.
Never plug the AC adaptor into a power source that does not correspond to both the voltage range and the frequency specified on the regulatory label of the unit. Failure to do so might result in a fire or electric shock, possibly resulting in serious injury.
Always use or purchase power cables that comply with the legal voltage and frequency specifications and requirements in the country of use. Failure to do so might result in a fire or electric shock, possibly resulting in serious injury.
The supplied power cord conforms to safety rules and regulations in the region the computer is bought and should not be used outside this region. For use in other regions, buy power cords that conform to safety rules and regulations in the particular region.
Do not use a 3-pin to 2-pin conversion plug.
When you connect the AC adaptor to the computer, always follow the steps in the exact order as described in this User’s Manual. As a general safety precaution, avoid touching any metal parts.
Never place your computer or AC adaptor on a wooden surface, furniture, or any other surface that might be marred by exposure to heat since the computer base and the surface of the AC adaptor increase in temperature during normal use.
Always place your computer or AC adaptor on a flat and hard surface that is resistant to heat damage.

Points to note about the Fingerprint Sensor

Be aware of the following considerations when using the fingerprint sensor. A failure to follow these guidelines might result in damage to the sensor, sensor failure, fingerprint recognition problems or a lower fingerprint recognition success rate.
Do not scratch or poke the sensor with your nails or any hard or sharp objects.
Do not press the sensor strongly.
User's Manual
4-8
Do not touch the sensor with a wet finger or any wet objects. Keep the sensor surface dry and free from water vapor.
Do not touch the sensor with a soiled or dirty finger as minute foreign particles of dust and dirt might scratch it.
Do not paste stickers or write on the sensor. Do not touch the sensor with a finger or any other object which might
have a build-up of static electricity on it.
Observe the following before you place your finger on the sensor whether for fingerprint enrollment/registration or recognition.
Wash and dry your hands thoroughly. Remove static electricity from your fingers by touching any metal
surface. Static electricity is a common cause of sensor failures, especially when the weather is dry.
Clean the sensor with a lint-free cloth. Do not use detergent or any other chemicals to clean the sensor.
Avoid the following finger conditions for enrollment or recognition as they might result in fingerprint enrollment errors or a drop in the fingerprint recognition success rate
Soaked or swollen finger, for example as might occur after taking a bath.
Injured finger Wet finger Soiled or oily finger Extremely dry skin condition on finger
Observe the following to improve the fingerprint recognition success rate.
Enroll two or more fingers. Enroll additional fingers if a recognition failure often occurs when using
already enrolled fingers. Check the condition of your finger. Any conditions which have
changed since enrollment, such as injury, rough skin, and extremely dry, wet, soiled, dirty, oily, soaked or swollen fingers, might lower the recognition success rate. Also if the fingerprint is worn down or the finger becomes thinner or fatter, the recognition success rate might be lowered.
As the fingerprint for each finger is different and unique you should ensure that only the registered or enrolled fingerprint or fingerprints are used for identification.
The fingerprint sensor compares and analyzes the unique characteristics in a fingerprint. However, there might be instances where certain users are unable to register their fingerprints due to insufficient unique characteristics in their fingerprints.
The recognition success rate might differ from user to user.

Battery

User's Manual
This section explains battery types, use, recharging methods and handling.
4-9

Battery pack

When the AC adaptor is not connected, the main power source of the computer is a lithium ion battery pack, also referred to in this manual as the main battery.

Real-Time Clock (RTC) function

The Real-Time Clock (RTC) function is supported. The main battery provides power for the internal real-time clock and calendar function and also maintains the system configuration while the computer is turned off. If the RTC lasting time completely runs out, the system will lose this information and the real-time clock and calendar will stop working.
You can change the Real-Time Clock settings in the dynabook Setup Utility. Refer to Real-Time Clock for further information.

Care and use of the battery pack

This section provides the important safety precautions in order to handle your battery pack properly.
Refer to the enclosed Instruction Manual for Safety and Comfort for detailed precautions and handling instructions.
Charge the battery pack only in an ambient temperature from 5 through 35 degrees Celsius. Otherwise, the electrolyte solution might leak, battery pack performance might deteriorate, and the battery life might be shortened.

Charging the battery

When the power in the battery pack becomes low, the DC IN/Battery indicator flashes amber to indicate that only a few minutes of battery power remain. If you continue to use the computer while the DC IN/Battery indicator flashes, the computer enters Hibernation Mode so that you do not lose any data, and automatically turn itself off.
You must recharge the battery pack when it becomes discharged.
Procedures
To recharge a battery pack, connect the AC adaptor to one of the Thunderbolt™ 3/USB Type-C™ ports and plug the other end into a working outlet. The DC IN/Battery indicator glows amber while the battery is being charged.
Charging Time
The following table shows the approximate time required to charge an exhausted battery fully.
User's Manual
4-10
Battery type Power off Power on
Battery pack
about 3 hours about 3 ~ 10 hours
(48 Wh)
Be aware that the charging time when the computer is on is affected by ambient temperature, the temperature of the computer and how you are using the computer. If you make heavy use of external devices for example, the battery might scarcely charge at all during operation.
Note that charging time will vary depending on the ambient temperature, the computer's internal temperature, and how the computer is being used. For example, whether the display is set to shut off automatically when idle, whether you make heavy use of external devices powered by the computer, or if the computer's internal storage drive is being accessed frequently by an application.
The battery might not be charged depending on how the computer is being used, and the charge of battery decreases and battery might not be fully charged sometimes.
If AC adaptor is connected via USB Type-C™ adapter, battery charging time might become longer.
Charging notice
The battery might not begin charging immediately under the following conditions:
The battery is extremely hot or cold (if the battery is extremely hot, it might not charge at all). To ensure the battery charges to its full capacity, charge it at room temperature of between 5°C to 35°C (41°F to 95°F).
The battery is nearly completely discharged. In this instance, leave the AC adaptor connected for a few minutes and the battery should begin charging.
The DC IN/Battery indicator might show a rapid decrease in battery operating time when you try to charge a battery under the following conditions:
The battery has not been used for a long time. The battery has completely discharged and been left in the computer
for a long time.
In such cases, do the following:
1. Fully discharge the battery by leaving it in the computer with the power on until the system automatically turns itself off.
2. Connect the AC adaptor to one of the Thunderbolt™ 3/USB Type-C™ ports on the computer, and to a wall outlet that is supplying power.
3. Charge the battery until the DC IN/Battery indicator glows white.
User's Manual
4-11
Repeat these steps two or three times until the battery recovers normal capacity.

Monitoring battery capacity

Remaining battery power can be monitored using the following methods.
Clicking the battery icon on the Windows Taskbar Via the Battery Status in the Windows Mobility Center window
Wait several seconds to monitor the remaining operating time because the computer needs time to check the remaining capacity of the battery pack and then calculate the remaining operating time, based on this together with the current power consumption.
Be aware that the actual remaining operating time might differ slightly from the calculated time.
With repeated discharges and recharges, the battery capacity will gradually decrease. In view of this, it is noted that an often used, older battery will not operate for as long as a new battery even when both are fully charged.

Maximizing battery operating time

The usefulness of a battery depends on how long it can supply power on a single charge, while how long the charge lasts in a battery depends on:
Processor speed Screen brightness Internal storage drive power off period How often and for how long you use the internal storage drive and
external disk drives, for example, optical disc How much charge the battery contained to begin with How you use optional devices, such as a USB device, to which the
battery supplies power Where you store your programs and data Whether you close the display panel when you are not using the
keyboard - closing the display saves power The environmental temperature - operating time decreases at low
temperatures System Sleep Mode System Hibernation Mode Display power off period Whether you enable Sleep Mode, which can conserve battery power if
you are frequently turning the computer off and on

Extending battery life

To maximize the life of your battery pack, do the following at least once a month.
1. Turn off the computer's power.
2. Disconnect the AC adaptor and turn on the computer's power. If it does not turn on then go to Step 4.
3. Operate the computer on battery power for five minutes. If you find that the battery pack has at least five minutes of operating time, continue operating until the battery pack is fully discharged. However, if the DC IN/Battery indicator flashes or there is some other warning to indicate a low battery condition, go to Step 4.
4. Connect the AC adaptor to one of the Thunderbolt™ 3/USB Type-C™ ports on the computer, and to a wall outlet that is supplying power. The DC IN/Battery indicator glows amber to indicate that the battery pack is being charged. However, if DC IN/Battery indicator does not glow, this indicates that power is not being supplied. Check the connections for the AC adaptor and the power cord.
5. Charge the battery pack until the DC IN/Battery indicator glows white.

Heat dispersal
*1
To protect against overheating, the processor is equipped with an internal temperature sensor which activates a cooling fan or lowers the processing speed if the computer's internal temperature rises to a certain level. You are able to select whether to control this temperature by either turning on the fan first, then if necessary lowering the processor speed, or by lowering the processor speed first, then if necessary turning on the fan. Both of these functions are controlled through the Power Options.
When the processor's temperature falls within normal range, the fan and the processor operation returns to its standard speed.
If the processor's temperature reaches an unacceptably high level with either setting, the computer automatically shuts down to prevent any damage. In this instance, all unsaved data in memory will be lost.

Troubleshooting
Dynabook has designed this computer for durability, however, should problems occur you are able to use the procedures detailed in this chapter to help determine the cause.
You should become familiar with this chapter as knowing what might go wrong can help prevent problems from occurring in the first place.

Problem-solving process

If you observe the following guidelines, resolving problems will be much easier.
Stop immediately when you recognize a problem exists as taking further action might result in data loss or damage, or you might destroy valuable problem-related information that can help solve the problem.
Observe what is happening. Write down what the system is doing and what actions you performed immediately before the problem occurred. Make a screenshot of the current display.
Also be aware that the questions and procedures described in this chapter are meant only as a guide, they are not definitive problem-solving techniques. In reality many problems can be solved simply, but a few might require help from Technical Support. If you find you need to consult others, be prepared to describe the problem in as much detail as possible.
Chapter 6

Preliminary checklist

You should always consider the simplest solution first. The items detailed in this checklist are easy to fix and yet can cause what appears to be a serious problem:
Make sure that you turn on all peripheral devices before you turn on the computer - this includes your printer and any other external device you are using.
Before you attach an external device you should first turn off the computer then when you turn the computer back on it recognizes the new device.
Make sure that all optional accessories are configured properly in the computer's setup program and that all required driver software has been loaded (refer to the documentation included with the optional accessories for further information on its installation and configuration).
User's Manual
6-1
Check all cables to ensure that they are correctly and firmly attached to the computer - loose cables can cause signal errors.
Inspect all connecting cables for loose wires and all connectors for loose pins.
Check that your disc media is correctly loaded
Always try to make detailed notes of your observations and keep them in a permanent error log - this helps you to describe your problems to Technical Support. In addition, if a problem recurs, the log you have made helps to identify the problem faster.

Analyzing the problem

Sometimes the computer gives you clues that can help you identify why it is malfunctioning. In view of this, keep the following questions in mind:
Which part of the computer is not operating properly - keyboard, HDD/ SSD, display panel, Touch Pad, Touch Pad control buttons - as each device produces different symptoms.
Check the options within the operating system to ensure that its configuration is set properly.
What appears on the display? Does it display any messages or random characters? Make a screenshot of the current display and, if possible, look up the messages in the documentation included with the computer, software, or operating system.
Check that all connecting cables are correctly and firmly attached as loose cables can cause erroneous or intermittent signals.
Do any indicators light, if so, which ones, what color are they and do they stay on or blink? Write down what you see.
Do you hear any beeps, if so how many, are they long or short and are they high pitched or low pitched? In addition, is the computer making any unusual noises? Write down what you hear.
Record your observations so you can describe them in detail to Technical Support.
Software The problems might be caused by your software
or disk. If you cannot load a software package, the media might be damaged or the program might be corrupted. In these instances, try loading another copy of the software if possible.
If an error message appears while you are using a software package, you should refer to the documentation supplied with it as this usually includes a problem-solving section or a summary of error messages.
Next, check any error messages against the operating system documentation.
User's Manual 6-2
Hardware If you cannot find a software problem, you should
then check the setup and configuration of your hardware. First run through the items in the preliminary checklist as described previously then, if you still cannot correct the problem, try to identify the source. The next section provides checklists for individual components and peripherals.
Before using a peripheral device or application software that is not an authorized part or product, make sure that the device or software can be used with your computer. Use of incompatible devices might cause injury or might damage your computer.
