1. Visit the memory accessory parts document for Value Line notebooks and record the memory part numbers compatible with your system.
   
   
2. Visit the memory compatibility document for Value Line notebooks and record the information about the maximum size, the speed, and the type of memory.
3. Remove all of the memory modules.
   
   
4. Compare the part number and other information collected in steps a and b above with the information listed on the label of each module. If the information does not match, then the module may not be supported on the system.

5. Re-insert the modules one at a time into a different slot than the slot they originally occupied. After inserting each module, check to ensure the memory detected matches the memory currently installed. If the memory does not match, then a module or slot may be defective.

   To open the Microsoft system properties:
   
   Windows Vista:
   1. Click Start and then click Control Panel.
   2. Double-click System.
   
   Windows XP:
   1. Click Start and then click Control Panel.
   2. Click Performance and Maintenance and then click System.
   
   Windows 2000:
   1. Click Start, select Settings, and then click Control Panel.
   2. Double-click System.
   
   To open the BIOS setup utility,
