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.

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.
