    Using Computers at LTS Computing Sites and Classrooms (FAQ)

    Computers at LTS facilities are part of a network that not only connects them to the internet, but also allows them to share software, data, and other resources such as printers. This guide explains how to use these computers, where to find assistance, and the policies governing their use.

    How do I log on to a Lehigh PC?

    Once any LTS computing site computer has been started and is ready for use, you will see the instruction to press Ctrl-Alt-Del to Login. Pressing the Ctrl, Alt, and Del keys will invoke a login dialog box. To log into the computer, enter your user name and password in the appropriate fields; press the Tab key to move between fields. Make sure "Log on to: AD" below the password field is visible. If it says something like "Log on to: PS-xxxxx" then you'll need to enter your username as "ad\username" in the username field. If it says "Log on to: FSxxxxxx" then it's a faculty/staff machine (you may still be able to login using ad\username if you have permission). When you are finished using a computer at an LTS Computing Site, REMEMBER TO LOG OUT. If you fail to log out, someone could access your email, coursework, or academic records. To log out, click on Start and choose Log Off from the Start Menu. Make sure you are completely logged out before you leave the PC. Often the logout process with require user confirmation or the process could hang. You are not logged out until the PC returns to the main Logon screen.

    How do I handle a locked workstation?

If you are not the user who is logged in you will need to turn the PC off and then on again. Hold the On/Off button down for at least 10 seconds or until you see the light behind the button disappear. Then, turn the PC back on, and log in as usual.

    What happens when I start up (or restart) a lab or classroom PC?

    On boot up the computer will display some messages as it loads it's operating system into memory. The system will briefly display a menu with two choices: Press F3 to ghost or wait 5 seconds for normal boot. If F3 is selected, the reload process will take 30- 40 minutes on a lightly loaded network with a 100Mb connection. Please do not touch the keyboard until the process is completed. It is important to not interrupt this process once it has started. Ghost Refresh - If you selected Ghost Single Refresh option, the computer will load software to connect to a remote image server and run ghost from this server to restore the hard drive image for this computing site computer. As it finishes, it will automatically reboot the computer twice more. The Ghost refresh resolves many computing issues, including printing problems, software errors, network problems, and more. When the refresh process is complete, all software not on the base image will have been removed from the hard drive (see software section below for an explanation). The computer will continue to start up Windows and then present you with the login screen.

    How long does it take for the screen saver to kick in?

    In order to protect users' confidential data, a password-protected screen saver has been implemented at the computing sites and computer classrooms. The timeout for classroom instructors stations is 2 hours, for all other computing site machines it is 10 minutes. The screen saver can be activated at any time by pressing the "Windows + L" keys on the keyboard. The original user can log back into the computer with the Lehigh password. If the original user has left the PC without logging off, the next user will need to shut the PC down and restart it.

    How can I help keep classroom and lab computers more secure?

    Invasive software (described by terms such as computer viruses, worms, and Trojan programs) can be spread around the world in a matter of days; anyone connected to the Internet can be at risk from invasive software. All LTS computing site computers have Microsoft Forefront protection software installed. You can also minimize risks from invasive software. Electronic mail. Avoid opening executable (.exe) attachments and attachments of that are unfamiliar or unexpected. Save attachments as files and run virus detection on them before opening them by right clicking on the file and scanning for viruses. Look out for phishing email, i.e. someone you don’t know or someone pretending to be someone else requesting sensitive and personal information from you. Phishing e-mail usually asks you to e-mail a password, or fill out a form on a non-Lehigh website (check the address bar) with your username and password. Never login any website with your Lehigh username and password if the site isn't part of the "" domain. Never e-mail your password to anyone, even someone at Lehigh. Web browsers. Download software with caution, and run virus detection on the files before running/installing them. Practice safe downloading practices by loading software from a trusted site.

    Connecting a Laptop to a Classroom Display

    Connecting a Laptop to a Classroom Display

    Step Number: 

    If possible, plug the laptop into a power source. We have learned from service personnel that many laptop manufacturers, in order to increase battery life, have reduced power output so severely that when power is drawn by using the hard drive, sync signal strength to external monitor ports (which is critical for connection to the projector) may be lost. Also, plugging into a power source ensures your battery won't quit in the middle of your presentation.

    Step Number: 

    Find your laptop's video output port, and plug in the available input cable. There are several kinds, and you may also need an adapter cable to connect your particular laptop to the input cable available in the classroom.

    video output ports
    Step Number: 

    Next, use the touch panel or push-button control to set the room's display system to use the 'Laptop' input. Most classrooms are equipped with some sort of video input switching control near the instructor's station or podium.

    Step Number: 

    Turn on your laptop's video output port. Most laptops have keyboard combinations to allow the video output to be toggled between three modes: 1) just to the laptop screen, 2) just to the output port, or 3) to both the screen and the port. We recommend using the 'Both' setting, so that you can see exactly what's on the screen.

    Step Number: 

    Adjust your laptop's display settings so that your laptop's screen is sent to the output port. Depending on your operating system and software, you'll have a utility or control panel for specifying how the system handles this external display. For Windows 7, go to Start > Control Panel > Display > Change Display Settings. We recommend choosing to 'Mirror' or 'Duplicate' the displays so that the laptop screen and the projector show the same thing, instead of 'Extending the Desktop' and having to move your presentation window over to the other screen. Note: Due to the differences between the size and resolution of your laptop screen and that of the projector, the image on your laptop screen will change.
