Understanding hard disk drive space

The hard disk drive on the Hewlett-Packard and

Compaq computers with the Microsoft®

Windows® operating system preinstalled may

appear to be smaller than the size stated in the

product specifications, in the documentation, or

on the box. Hard disk drives are described and

advertised by manufacturers in terms of decimal

(base 10) capacity. Microsoft Windows and

other programs, such as FDISK, use the binary

(base 2) numbering system.

In decimal notation, one megabyte (MB) is

equal to 1,000,000 bytes, and one gigabyte

(GB) is equal to 1,000,000,000 bytes. In the

binary numbering system, one megabyte is

equal to 1,048,576 bytes, and one gigabyte is

equal to 1,073,741,824 bytes. Because of the

different measuring systems, you may see a

difference between the size reported by

Microsoft Windows and the size advertised. The

storage capacity of the hard disk drive is as

advertised.

Microsoft Windows reports smaller capacity in

the Windows Explorer tool and in the computer

window because it shows information about one

partition on the hard disk drive at a time. One of

the partitions contains the System Recovery

information.

Note about systems configured with 4 GB of

memory

For computers with a 32 bit operating system,

all memory above 3 GB may not be available

because of system resource requirements.

This limitation is not limited to HP and Compaq

systems. The memory above 3 GB is used for

system resources.

Confirming total memory

The system BIOS displays the full 4 GB of

installed memory.

1. Turn on the PC.

2. Press F10. The BIOS menu is displayed.

Confirm the Total Installed Memory.

If you are using built-in monitor speakers, use the monitor front-panel Volume button to

adjust volume. Use the front-panel buttons to enter the on-screen display (OSD) and ensure

that audio is enabled and that the volume is set appropriately.

Ensure that you connected powered (active) speakers and that they are turned on.

Turn off your computer, and then unplug and reconnect the speakers. Ensure that the

speakers are connected to an audio connector, not a Line In or headphone connector.

To resume from Sleep mode, press the Sleep button (select models only), or press Esc.

Unplug headphones if they are connected to your computer (or speaker system).

Internet access

Symptom Possible solution

Internet programs

do not start

automatically.

Log in to your ISP, and start the desired program.

12 Chapter 3 Troubleshooting and maintenance ENWW

Symptom Possible solution

I cannot connect

to the Internet.

For Windows 7:

1. Click Start, click Control Panel, click Action Center, and then click

Troubleshooting.

2. Under Network and Internet, click Connect to the Internet.

Verify that you are using the proper cables for your Internet connection type. Your

computer might have a dial-up modem and an Ethernet network adapter (also called a

network interface card, or NIC). A modem uses a standard telephone cable, whereas the

network adapter uses a network cable, to connect to a local area network (LAN). Do not

connect a telephone cable to the network adapter, and do not plug a network cable into a

telephone service line; doing so might damage the network adapter.

Run the wireless setup wizard:

1. Click Start, click Control Panel, click Network and Internet, and then click Network

and Sharing Center.

2. In the Network and Sharing Center window, click Set up a connection or network

to open the wizard, and then follow the on-screen instructions.

If your system has an external antenna, try to move the antenna to a better position. If the

antenna is internal, try to move the computer.

Try to connect again later, or contact your Internet service provider (ISP) for assistance.

Software troubleshooting

To repair software

problems, try

these methods:

●

Turn the computer off completely and then turn it on again. This is the easiest (and

sometimes the best) way.

● Update the drivers (see Updating device drivers, following).

●

Use Microsoft System Restore Software program and hardware driver reinstallation

(see Microsoft System Restore, later in this table). — Restores your computer to a

configuration that was in use before the software was installed.

●

Reinstall the software program or hardware driver (see Software program and

hardware driver reinstallation, later in this table). — Restores the software (if it came

with the product) or hardware driver to factory defaults.

●

System Recovery (see

System recovery on page 18) — Erase and reformat the

hard disk drive, and then reinstall the operating system, programs, and drivers. This

erases all data files you have created.
