HP Write Filters The File-Based Write Filter (FBWF) and the Enhanced Write Filter (EWF) provide two distinct ways to provide a secure environment for your computer by protecting it from unauthorized writes to storage and file systems. FBWF operates at the file level, and EWF operates at the sector level. Only one write filter can be selected and active at one time.
If you are logged on as an administrator, you can change the status of FBWF by right-clicking the icon and selecting the desired FBWF state. NOTE: Because the fbwfmgr.exe utility and the FBWF status service execute separate code, status changes made by fbwfmgr.exe are not automatically reflected by the FBWF status icon.

Wireless About integrated wireless devices Wireless technology transfers data across radio waves instead of wires. Your computer may be equipped with a wireless local area network (WLAN) device. This device connects the computer to wireless local area networks (commonly referred to as Wi-Fi networks, wireless LANs, or WLANs) in corporate offices, your home, and public places such as airports, restaurants, coffee shops, hotels, and universities.
NOTE: You must commit these changes in order for them to be saved. For additional information, refer to HP Write Filters on page NOTE: The functional range (how far your wireless signals travel) depends on WLAN implementation, router manufacturer, and interference from other electronic devices or structural barriers such as walls and floors.
Use a firewall. ● Set security on your Web browser. For more information about WLAN security, see the HP Web site at (English only). Identifying a WLAN device If you have a problem connecting to a wireless network, follow these steps to confirm that the integrated WLAN device is properly installed on your computer: Click Start, and then click All Programs.
Modem and LAN Using a modem The modem must be connected to an analog telephone line by using a 6-pin, RJ-11 modem cable (purchased separately). In some countries or regions, a specific modem cable adapter is also required. Jacks for digital PBX systems may resemble analog telephone jacks, but they are not compatible with the modem.
Connect the modem cable into the RJ-11 telephone wall jack (2). Connecting a country- or region-specific modem cable adapter Telephone jacks vary by country or region. To use the modem and the modem cable outside the country or region in which you purchased the computer, you must obtain a country- or region-specific modem cable adapter.
You must commit these changes in order for them to be saved. For additional information, refer to HP Write Filters on page Adding new locations when traveling By default, the only location setting available to the modem is a location setting for the country or region in which you purchased the computer.
Page 55
An analog telephone line supports one of 2 dialing modes: pulse dialing or tone dialing. These dialing mode options are selected in the Phone and Modem Options settings. The dialing mode option selected must match the dialing mode supported by the telephone line in your location. To determine the dialing mode supported by a telephone line, dial a few digits on the telephone, and then listen for clicks (pulses) or tones.
Connecting to a local area network Connecting to a local area network (LAN) requires an 8-pin, RJ-45 network cable (purchased separately). If the network cable contains noise suppression circuitry (1), which prevents interference from TV and radio reception, orient the circuitry end of the cable (2) toward the computer. To connect the network cable, follow these steps: Connect the network cable into the network jack (1) on the computer.
