Usage Notices

All functionality, features, specifications, and other device information provided in

this document, including but not limited to, benefits, design, pricing, components,

performance, availability, and capabilities of the device are subject to change without

notice. Samsung reserves the right to alter this document or the device described herein

at any time, without obligation to provide notification of such changes.

Precautions for Repair

Samsung is not liable for any damage or defect determined to be caused by repair by

a non-authorized carrier, self repair or non-professional repair of the device. Samsung

is not liable for any resulting damage to the device, or any injury or other device safety

issue caused by any attempt to repair the device which does not follow these repair and

maintenance instructions.

Any damage to the device or defect caused by an attempt to repair the device by any

person other than a Samsung certified carrier will not be covered by the warranty.

•

Use only demagnetized tools that are specifically designed for small electronic

repairs, as most electronic parts are sensitive to electromagnetic forces.

•

Use only high quality screwdrivers when servicing devices. Low quality screwdrivers

can easily damage the heads of screws.

•

Always use genuine replacement parts. Third-party replacement parts may not

function properly and could cause a fire or injury.

•

If you need to access the failure data of your device or need to get a more detailed

diagnosis, visit a Samsung Service Center.

•

If you need to replace unsold parts, visit a Samsung Service Center and receive

further instruction.

•

Before conducting repairs, remember to make backup copies of all important data

stored in the device.

•

Make sure to wear the appropriate safety equipment before carrying out repairs.

Samsung is not responsible for injuries that may occur because of not wearing the

proper safety equipment. Refer to Tools for Disassembly and Assembly for a list of

tools that you will need for assembling and disassembling the device.

•

Repair the device in a safe place.

Visit www.samsung.com to view the device information, related material, and safety

information.

ESD (Electrostatic Discharge) Precautions

It is the sudden flow of electricity between two electrically charged objects caused by

contact, an electrical short, or dielectric breakdown. ESD can cause negative effects on

mobile phone, especially electrical parts.

•

It is recommended to use ESD safety (Anti-static) equipment such as an anti static

wrist strap and gloves, and an ESD safe mat when repairing the device.

•

Increase the airflow to the work area to decrease the chance of accidental static

electricity discharges, as the potential for static electricity discharge may be

increased in low-humidity environments, such as air-conditioned rooms.

What is a Recovery Area?

The computer has an additional partition for restoring data or saving backup files (only

for models with the

Samsung Recovery

app). This partition is called a Recovery Area and

it includes a recovery image comprised of the operating system and apps.

Why is the capacity representation of the hard disk drive (HDD) in Windows

different from the product specifications?

The capacity of the storage device (HDD or SSD) of the manufacturer is calculated

assuming that 1 KB = 1,000 Bytes. However, the operating system (Windows) calculates

the storage device capacity assuming that 1 KB = 1,024 Bytes, and therefore the capacity

representation of the HDD in Windows is smaller than the actual capacity. The capacity

representation in Windows may be smaller than the actual capacity because some apps

occupy a certain area of the HDD outside of Windows.

For models with the

Samsung Recovery

app, the HDD capacity representation in

Windows may be smaller than the actual capacity because the

Samsung Recovery

app

uses a hidden area of 5–20 GB of the HDD to save the recovery image, and that hidden

area is not counted towards the total size available to Windows. The size of the

Samsung

Recovery

app varies by model.

What is a recovery image?

This refers to the operating system, drivers, and software that are converted to a data

image. It is required to recover the computer and is embedded in the computer’s HDD.

However, this is not provided for storage devices where the capacity is less than 64 GB.

How can I restore a computer that does not have the Samsung Recovery app?

Restore the computer with the recovery function provided by Windows. Refer to the

Recover Functionality item in the help for more details.

Miscellaneous

The camera and the microphone are not working. How do I turn them on again?

When recording protect mode is activated, the camera and microphone will not work.

select the

Block camera and mic

switch to set it

.

The computer does not turn on automatically when the display panel is opened.

To turn on the computer, the display panel should be opened greater than a certain

angle.

The angle may differ depending on the model.

If the computer LED does not turn on automatically, press the Power button.
