Using The Glide Pad

Your computer is equipped with an integrated pointing device called a glide pad. Using the glide pad, you can move the pointer, select an item from a menu, and perform other tasks in the same way you would with a mouse.

Do not hit or scratch the surface of the glide pad with pointed objects

Using the Glide Pad

Take a moment to become familiar with how the glide pad works.

•

(such as a ballpoint pen). Do not operate the glide pad with a moist finger. This may cause the

•

glide pad to operate incorrectly.

Place Your Fingertip

Place your left or right hand next to the glide pad, resting your wrist naturally in a relaxed manner. Place your thumb or finger on the glide pad.

Move Your Fingertip

The rectangul ar pad of the gli de pad acts l i ke a miniature duplicate of the disp l ay. As you slide your fingertip across the pad, the pointer on the screen moves in the same direction across the screen. The glide pad is very sensitive, so you do not have to exert much pressure on the pad. The glide pad will respond to a light touch from your fingertip.

2-4

Click, Double-click, and Right-click

To click or double-click, you can use the left button just like that of a mouse. Instead of clicking the left button, you can also just tap gently anywhere on the rectangular pad. For right-clicking, you can use the right button or tap the pad with three fingers.

Drag and Drop

You can move icons or windows by using “drag and drop” below:

1. Position the pointer over the object.

2. Press the left button; do not release it.

3. Holding down the button, move the pointer. The object moves together with the

pointer.

4. Release the button when the object reaches its destination.

Scroll

You can scrol l through informatio n in a list or in a document by using the glide pad. To view information vertically, place your finger on the most right part of the glide pad and slide your finger up and down. To view information horizontally, place your finger on the bottom part of the glide pad and slide your finger left or right. This procedure works in limited applications. See Windows help for more information.

Troubleshooting

This chapter describes how to troubleshoot computer problems.

Common Problems

Problems with your computer can be caused by something as minor as an unpl ugged power cord or as major as a damaged hard disk drive. The information in this troubleshooting section is d esigned to help you fi nd and solve minor problems. If you still have a problem after trying all the suggested remedies in this chapter, contact your dealer.

The problems that you might encounter can be divided into two basic categories: hardware and software. Hardware problems can be further divided into being of an electrical or a mechanical nature. You will know you have a hardware problem if, for example, the screen is blank, or the computer cannot recognize the disk drives.

Software problems can occur at several levels. Both your operating system and your software application programs are capable of generating errors and error messages. If you encounter a software error, try to determine if the error message is from your operating system or from an application program, and refer to the appropriate manual for possible remedies.

You can also refer to the Windows 98 manual or Windows Help program to solve the problem. To access the Help program, select Help from the Start menu. It also gives you Troubl eshooting tips and an Index.

Successful troubleshooting is the result of careful observation, deductive reasoning, and an organized approach to solving the problem. If you encounter a problem, begin by performing a careful visual inspection. Check the exterior of the computer first. If no lights are displayed, check the battery charge or power outlet, the plug and power cord, and any power switches that may affect your computer. If the comp uter has been connected to any peripheral devices, look for loose or disconnected cables. You may also need to check the fuses and breakers in your electric box. A few common problems and suggested solutions are presented in the examples which follow.
