COMPUTER TROUBLESHOOTING



TSD WORKSTATIONS COMMITTEE


This troubleshooting guide is intended for use by members of the TSD Workstations Committee. As staff become more comfortable with their workstations, they can be trained in some of the more straightforward solutions. Only Committee members and some managers should be performing a defrag. on the hard disk.

PROBLEM SOLUTION
No power Check all on/off switches, power strip (if used), wall outlet
Are all cables securely attached
Power coming through but monitor is blank Check that monitor is turned on
Touch mouse to activate a blank screensaver
Check that monitor brightness control has not been turned way down
Screen images out of alignment Use monitor controls to adjust
Mouse is jerky or sticks Open up back and blow, if small metal part is dirty, contact Johnny
PM group is not apparent Click on Window menu and identify group from the listing, or, minimize any open group--your group icon may be hiding
Icon is missing from group Identify original group and copy icon into appropriate group
Icon missing entirely from PM * Highlight group, click on File menu, select New, select Program Item, in Properties box click on description, type in item name, click on command line, use browse to identify appropriate exe file
Click on icon and Application Execution Error message appears * Highlight icon, click on File menu, select Properties, click on command line, use browse to identify appropriate exe file
Click on icon and nothing happens Check task list to make sure that application is not already open
Insufficient memory or not enough memory Close down unwanted applications
In PM, click on Help, then About, if free resources less than 55%, close all applications, exit Windows, at C prompt type win to restart
Application is frozen but Windows is still responding Make sure application is frozen by moving mouse, try and minimize. Press ctrl./alt./del. & look to see which application has stopped responding. Return to Windows, close all other applications, exit Windows, at C prompt type win to restart.
Application(s) and Windows are frozen Make sure application is really frozen by moving mouse, try and minimize. Press ctrl./alt./del. & look to see what application has stopped responding. Return to Windows, press ctrl./alt./del. Restart the computer. This is known as a warm boot.
One of the applications which has frozen is TCP3270 or RLIN Make sure application is really frozen by moving mouse, try and minimize. Press ctrl./alt./del. & look to see which application has stopped responding. Return to Windows, close all other applications, exit Windows. At C prompt turn computer off at the power button, wait up to 30 sec. & turn back on, at C prompt type win. This is known as a cold boot. Necessary with networking applications to clear the account.
Logging onto TCP3270 get an Unable to create socket message Close all open applications and press the reset button (warm boot)
Many workstations cannot access TCP3270 sessions Mainframe problems at CIT, check to see if any messages on e-mail, contact Systems Office to notify of problem/or get time estimate
Logging onto RLIN get a Cannot connect to Host message Close all open applications and do a cold boot.
Printer will not print in any application Are the cables secure.
Is it plugged in.
Is the printer online
Printer will not print in TCP3270 * This application does not use Print Manager, check with Janet
Printing in TCP3270 but not in RLIN * Select Main, Control Panel, Printers, check to see if the default printer matches the printer make, see Janet
Printing very slow in RLIN Select Settings, Terminal, deselect Graphics Printing (will loose diacritics)
Computer is running very slow * Open Netscape, select Preferences, select cache & network, clear out memory & disk cache.
Computer is still slow * Hard disk may need to be defragmented. Close all applications and exit Windows to C prompt. Type defrag, select drive C, let the program run

* Check with Janet before doing one of these the first time, or until you are comfortable.
