Log in to the “Sign Up” stations near the main entrance and select “PC” or “Mac” and you will be assigned to the next available computer.

Only Cal Poly students, faculty and staff can reserve PolyConnect computers and you can only reserve them from the Sign Up stations in the lab.

Why did I get an error message when I tried to log in to a computer?

  • Error message: “Pharos: The username and password could not be authenticated against servers.”
    This means you entered your user name or password incorrectly or that your Portal password is “out of sync” with an active directory password. The solution is to reset the password from the Portal ( or call Campus ITS at 805-756-7000 for assistance with resetting your password.
  • Error message: “domaine is blocked” or the “account is locked.”
    This usually means all computers in the library are locked. Alert a Computer Support Assistant (PolyConnect or Learning Commons desk) if you see this message. If this happens in the evening or on the weekend, users may have to wait until the account “unlocks itself” which may take up to 30 minutes.
  • Error message: “You cannot use this computer, you already have an active session on computer xx-xx-xx.”
    This means that you are logged in to another computer in the library. Perhaps you did not log off earlier today and someone else is using your login. You can find that computer, ask the user to log off or find another non-PolyConnect computer and log in as a guest.

The computer is on but the monitor is black, what should I do?

First, press the power button in the lower right corner. If that doesn’t work, carefully disconnect/reconnect the monitor’s power cable to “reboot” the monitor. You might have to restart the computer too. A Computer Support Assistance at the PolyConnect desk can help you restart a monitor.

Why am I seeing an error message about an expired software license?

Notify a Computer Support Assistant at the PolyConnect desk or call Library IT at 805-756-1189 and we will assist you with accessing the software.

I can’t find a document that I edited and was attached to an email. Where did it go?

Open the program (Word, Excel, etc.) and look in “Open Recent” documents. If not there, select the LibLabs-user shortcut on desktop and look in My Documents. If not there, your document may have been saved to a temporary Internet file and cannot be retrieved.

To avoid this problem, “Save As” your attached documents to the desktop or USB drive before you edit and save.
