Touch screen instructions

This chapter contains the following topics:

▶ Touch Screen Calibration
➢ User Gesture Instructions for the Touch screen
➢ Attentions when using the Touch Screen

Attention: Only selected models are equipped with a touch screen.

The monitor is touch-sensitive thanks to its touch-sensitive screen. A touch screen is an input device just like a mouse or a keyboard, and the user's fingers transmit position information via the touch screen to the computer. With this technology, you only need to touch the pictures or words on the computer display lightly with your finger, and the computer will react.

Touch Screen Calibration

Prior to first use or whenever the touch screen reacts in a different place where you are touching it, start the calibration program. The procedure is as follows:

1. In Control Panel, select "Hardware and Sound".
2. In "Hardware and Sound" window, select "Tablet PC Settings".
3. In "Tablet PC Settings" dialogue, click "Calibrate" button.
4. To finish the calibration, use your finger or a more than 9 mm diameter touch pen to touch each of the calibration points shown in sequence.

User Gesture Instructions for the Touch screen

The Touch screen supports single touch and rotational movements, enlargement and reduction multi-touch operations, and the user can transmit position information to the computer via touch. The touch screen uses a very low pressure movement recognition method, which only needs the finger to move lightly on the computer display screen or make a simple hand gesture to be detected by the main computer processor.

Note: Do not touch the screen with any hard objects, such as fingernails.

Basic Hand Gestures

1. Single Click / Double Click

For the item selected on the touch screen, with one finger touch it one or two times, to perform a single click or double click operation. This is similar to the action performed by clicking the mouse left button.

2. Single Finger Right Click

For the item selected on the touch screen, press and hold your finger on the screen until a circle appears. After lifting your finger from the touch screen, a menu bar will pop up, completing the single finger right click operation. This is similar to the action performed by clicking the mouse right button.

Hand pointing at a square button on a gray background (no text or symbols)

3. Dragging Movement

First touch your finger on the desired item on the screen and hold it there, then make a dragging movement. This is similar to the click and drag movement you can make with a mouse.

4. Rolling Movement

When you move your finger one time vertically (or horizontally) on the touch screen, this is called a Rolling Operation. For example: This operation is similar to moving the scroll wheel on the top of a mouse, and produces the same results as the scroll wheel interface does.

5. Zoom Operation

Touch two fingers lightly on the desired item on the touch screen, then keeping both fingers on the screen, change the distance between them. By increasing (or decreasing) the distance, you can perform a zoom in (or zoom out) operation. For example: you can enlarge or reduce the picture size in Windows Photo Viewer.

Note: To learn more about how to use the touch screen, refer to Windows Help and Support by press Windows key F1 or Select Settings charm, then select Help.

Related Touch Screen Settings

• Select Hardware and Sound→ Pen and Touch from the Settings charm.
• Select touch actions which you wish to adjust. By clicking on "Settings", you can adjust the "Speed" and "Spatial tolerance" parameters, to match the user's natural way of double-clicking. You can double-click on the lower right corner of the icon to test this.

Note: Users can access more help information from the Windows Help and Support menu.

Precautions when using the Touch Screen

1. When using the touch screen, be careful not to tear the surface with any sharp objects.

Illustration of a hand pointing at a computer monitor with a pencil and a large 'X' symbol (no text or symbols present)

1. To ensure normal use of the touch screen, ensure that both the screen surface and your fingers are clean and dry.

2. To ensure precise positioning on the touch screen, avoid handling or touching the glass frame when you are touching the screen.

3. Turn the computer off for safety before cleaning the screen and frame with a soft cotton cloth. Do not wipe it with a wet cloth as this may leave a water mark and affect touch operation.

4. Do not place or drop anything which could obstruct it in the four corners of the screen or any part of its frame, because this could separate the screen from the frame and stop the screen from being able to sense position properly. Please avoid leaving water and dust in the gap between the casing and glass when you are cleaning the frame.

5. Avoid using the touch screen in dusty environments or hot or humid conditions. Any abrupt temperature change may cause condensation on the inside surface of the glass screen, which will disappear after a short time and does not affect normal use.

6. Do not spray any liquid or cleaner directly onto the touch screen.

7. Do not use a solvent or industrial alcohol-based cleaners.

8. Avoid using the computer in sunlight, which will affect the function of the touch screen.
   Note: The touch screen will not affect other computer processes when used normally.

9. Recognition of touch gestures can be influenced by the following:

10. Touching the correct place on the screen.
    • The speed of movement.
    • The time interval from when the screen was last touched.

Note: The user can consult this manual and also the related Windows help content to learn accurate hand gestures.

1. The touch screen does not function in Rescue System mode.
2. The touch screen also does not function during the startup process, in Hibernate mode and in Sleep mode or Safe mode.
3. Do not touch the screen with your finger or any other objects during the computer startup or wake up process.

2. Confirm that the CD/DVD has been properly placed in the drive. If not, reload the CD or DVD. Otherwise, continue with the next step of this procedure.
3. Check the specifications that came with your computer to confirm that this optical drive is capable of reading this type of CD or DVD.
4. If the CD/DVD cannot be read, replace it with a known good CD/DVD such as one that was shipped with the computer.
5. If the known good CD cannot be read, visually check the operating side of the CD/DVD for defects.

Problem: The capacity of the hard disk, as indicated by the system, is less than the nominal capacity.

Troubleshooting and problem resolution: For computers equipped with the OneKey Recovery feature, the system recovery feature needs to occupy some hard disk space. This may account for the apparent hard disk capacity deficit.

Further Technical Explanation: The nominal capacity of the hard disk is expressed in the decimal system as 1000 bytes. But the actual hard disk capacity is expressed in the binary system as 1024 bytes (For example, the nominal capacity 1G is 1000M, while the actual capacity 1G is 1024M).

The capacity of the hard disk shown in Windows can be calculated according to the calculations in the following example:

The nominal capacity of the hard disk is 40G, while its actual capacity should be: 40 × 1000 × 1000 × 1000/(1024 × 1024 × 1024) = 37G .

If the Service partition of 3G - 3 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 2.79G is subtracted, the capacity of the hard disk shown in the system can be obtained.

The capacity of the hard disk as calculated using this method may be slightly different from the actual capacity due to the rounding of totals.

Special considerations for troubleshooting Windows

Record the following information as it may be useful later when troubleshooting system problems:

The drivers for this computer model only support the Windows 8.1 system.

Windows Help and Support

If you have a problem with the operating system, see the Windows Help and Support file. To open the Windows Help and Support file, do one of the following:

• Select the Settings charm, then select Help.
• Press Windows key + F1.

Because many of the computer components consist of sophisticated integrated circuit boards, it is very important to periodically clean the computer to prevent dust buildup. The cleaning supplies you need to clean the components include: a vacuum cleaner, a soft cotton cloth, pure water (preferably purified or distilled water) and cotton swabs.

Attention: Before you clean your computer, disconnect the computer from the electrical outlet. Clean your computer with a soft cloth dampened with water. Do not use liquid or aerosol cleaners, which may contain flammable substances.

Note: To avoid damaging the computer or display, do not spray cleaning solution directly onto the display. Only use products specifically designed for cleaning displays, and follow the instructions included with the product.

The following are general methods for cleaning the components:

• You can use a soft cloth to remove dust on the surface of the computer, the monitor, the printer, the speakers and the mouse.
• You can use a vacuum cleaner to clean in otherwise inaccessible corners.
• To clean the keyboard thoroughly, shut down the computer and scrub it gently with a wet cloth. Do not use the keyboard until it is dry.

Do not do any of the following:

• Allow water to enter the computer.
  • Use a heavily dampened cloth.
• Spray water directly onto the surface of the monitor or inside the computer.

LCD monitor should be cleaned daily. Use a dry cloth to brush dust from the monitor and keyboard every day. Keep all surfaces clean and free of grease stains.

Hardware Replacement Guide

This chapter contains the following topics:

Removing the stand base
Removing the foot cover
▶ Replacing a memory module
▶ Replacing the hard disk drive

Overview

This guide is intended to be used by customers who are replacing Customer Replaceable Units (CRUs) as well as trained service personnel who are replacing Field Replaceable Units (FRUs). In this guide, CRUs and FRUs will often be referred to as parts.

Note: Trained service personnel should refer to the Hardware Maintenance Manual (HMM) for parts ordering information.

This guide does not include procedures for all parts. It is expected that cables, switches, and certain mechanical parts can be replaced by trained service personnel without the need for step-by-step procedures.

Note: Use only parts provided by Lenovo®.

The description of the TV-Tuner card in this manual applies only to those computer models that have a TV-Tuner card installed.

This guide contains procedures for replacing the following parts:

• Memory module
• Hard disk drive

Safety information for replacing CRUs

Do not open your computer or attempt any repairs before reading the “Important safety information” in the Safety and Warranty Guide that was included with your computer. If you no longer have this copy of the Safety and Warranty Guide, you can obtain one online from the Support Web site at http://support.lenovo.com.

Tools required

To disassemble the computer, you need the following tools:

• Wrist grounding strap and conductive mat for preventing electrostatic discharge
- Flat head screwdriver
• Phillips head screwdriver
- Hex screwdriver
• Plastic flat head screwdriver
- Plastic tweezers

Note: The screws for the different components vary in size. During the disassembly procedure, group the screws with their corresponding components to avoid a mismatch when replacing the components.

Handling static-sensitive devices

Static electricity, although harmless to you, can seriously damage computer components.

When you are replacing a part, do not open the anti-static package containing the new part until the defective part has been removed from the computer and you are ready to install the new part.

When you handle parts and other computer components, take these precautions to avoid static electricity damage:

• Limit your movements, as this can cause static electricity to build up.
• Always handle parts and other computer components carefully. Handle adapters, memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.
• Prevent others from touching the parts and other computer components.
• Before you replace a new part, touch the anti-static package containing the part to a metal expansion slot cover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity in the package and your body.
• When possible, remove the new part from the anti-static packaging and install it directly in the computer without setting the part down. When this is not possible, place the anti-static package that the part came in on a smooth, level surface and place the part on it.
• Do not place the part on the computer cover or other metal surface.

Replacing hardware
