10 Security Protecting the computer NOTE: Security solutions are designed to act as deterrents, but they may not deter software attacks or prevent the computer from being mishandled or stolen. Security features provided with your computer can protect the computer, personal information, and data from a variety of risks. The way you use your computer will determine which security features you need to use. The operating system offers certain security features.
Use the following tips for creating and saving passwords: ● When creating passwords, follow requirements set by the program. ● Write down your passwords and store them in a secure place away from the computer. ● Do not store passwords in a file on the computer. The following tables list commonly used passwords and describe their functions. Setting passwords in the operating system Operating system passwords Function Root password Protects access to an operating system root-level account.
Your changes take effect when the computer restarts. Entering a BIOS administrator password At the Enter password prompt, type your administrator password, and then press enter. After 3 unsuccessful attempts to enter the administrator password, you must restart the computer and try again.
At the DriveLock Password prompt, type your user or master password (using the same kind of keys you used to set the password), and then press enter. After 2 incorrect attempts to enter the password, you must shut down the computer and try again. Using Computer Setup Automatic DriveLock In a multiple-user environment, you can set an Automatic DriveLock password. When the Automatic DriveLock password is enabled, a random user password and a DriveLock master password will be created for you.
NOTE: When modifying firewall settings, you are prompted for the root password. Installing an optional security cable NOTE: A security cable is designed to act as a deterrent, but it may not prevent the computer from being mishandled or stolen. NOTE: The security cable slot on your computer may look different from the illustration in this section. See Getting to know your computer on page 3 for the location of the security cable slot on your computer. 1. Loop the security cable around a secured object.

The following diagnostic tests are available in Advanced System Diagnostics: ● Start-up test—This test analyzes the main computer components that are required to start the computer. ● Run-in test—This test repeats the start-up test and checks for intermittent problems that the start-up test does not detect.
13 MultiBoot About the boot device order As the computer starts, the system attempts to boot from enabled boot devices. The MultiBoot utility, which is enabled at the factory, controls the order in which the system selects a boot device. Boot devices can include optical drives, diskette drives, a network interface card (NIC), hard drives, and USB devices. Boot devices contain bootable media or files that the computer needs to start and operate properly.
Enabling boot devices in Computer Setup The computer will boot to a USB device or a NIC device only if the device has first been enabled in Computer Setup. To start Computer Setup and enable a USB device or a NIC device as a boot device, follow these steps: 1. Turn on or restart the computer, and then press esc while the “Press the ESC key for Startup Menu” message is displayed at the bottom of the screen. 2. Press f10 to enter Computer Setup. 3.
● The computer will boot from a NIC device only if the device has been enabled in the Built-In Device Options menu of Computer Setup and if booting from the device has been enabled in the Boot Options menu of Computer Setup. Booting from a NIC does not affect logical drive designations because no drive letter is associated with the NIC. ● Drives in an optional docking device are treated like external USB devices in the boot order.
Dynamically choosing a boot device using the f9 prompt To dynamically choose a boot device for the current startup sequence, follow these steps: 1. Open the Select Boot Device menu by turning on or restarting the computer, and then pressing esc while the “Press the ESC key for Startup Menu” message is displayed at the bottom of the screen. 2. Press f9. 3. Use a pointing device or the arrow keys to select a boot device, and then press enter. Your changes go into effect immediately.
A Troubleshooting and support Troubleshooting The following sections describe several common issues and solutions. The computer is unable to start up If the computer does not turn on when you press the power button, the following suggestions may help you determine why the computer does not start up: ● If the computer is plugged into an AC outlet, plug another electrical device into the outlet to be sure that the outlet is providing adequate power.
CAUTION: Emergency shutdown procedures result in the loss of unsaved information. ● Press and hold the power button for at least 5 seconds. ● Disconnect the computer from external power and remove the battery. The computer is unusually warm It is normal for the computer to feel warm to the touch while it is in use. But if the computer feels unusually warm, it may be overheating because a vent is blocked. If you suspect that the computer is overheating, allow the computer to cool to room temperature.
The computer does not detect the optical drive If your operating system does not detect an installed device, the device driver software may be missing or corrupted. 1. Remove any discs from the optical drive. 2. Click Computer and then click System Monitor. 3. On the Hardware tab, identify the Storage Controller in the Type column. 4. Click the triangle next to the devices until you locate your optical drive. If the drive is listed, it should be functioning correctly.
The process of burning a disc does not begin, or it stops before completion ● Be sure that all other programs are closed. ● Turn off Suspend mode and Hibernation. ● Be sure that you are using the right kind of disc for your drive. ● Be sure that the disc is inserted properly. ● Select a slower write speed and try again. ● If you are copying a disc, save the information on the source disc to your hard drive before trying to burn the contents to a new disc, and then burn from your hard drive.
Labels The labels affixed to the computer provide information you may need when you troubleshoot system problems or travel internationally with the computer: IMPORTANT: All labels described in this section will be located in one of 3 places depending on your computer model: Affixed to the bottom of the computer, located in the battery bay, or under the service cover. For help finding these locations, refer to Getting to know your computer on page 3.
Component 74 (3) Serial number (4) Product number ● Regulatory label—Provides regulatory information about the computer. ● Wireless certification label or labels (select models only)—Provide information about optional wireless devices and the approval markings of some of the countries or regions in which the devices have been approved for use.
B Cleaning your computer Cleaning products Use the following products to safely clean your computer: ● Dimethyl benzyl ammonium chloride 0.3 percent maximum concentration (For example: disposable wipes. These wipes come in a variety of brand names.
Cleaning the TouchPad, keyboard, or mouse WARNING! To reduce the risk of electric shock or damage to internal components, do not use a vacuum cleaner attachment to clean the keyboard. A vacuum cleaner can deposit household debris on the keyboard surface. CAUTION: To prevent damage to internal components, do not allow liquids to drip between the keys.
C Specifications Input power The power information in this section may be helpful if you plan to travel internationally with the computer. The computer operates on DC power, which can be supplied by an AC or a DC power source. The AC power source must be rated at 100–240 V, 50–60 Hz. Although the computer can be powered from a standalone DC power source, it should be powered only with an AC adapter or a DC power source supplied and approved by HP for use with this computer.
D Electrostatic discharge Electrostatic discharge is the release of static electricity when two objects come into contact—for example, the shock you receive when you walk across the carpet and touch a metal door knob. A discharge of static electricity from fingers or other electrostatic conductors may damage electronic components.
