Unclean Screen Hinges
If the computer hinges have dirt or sand in them, the screen may not lift smoothly. Try cleaning the computer hinges by dissembling the laptop. Once you can see the hinges, use a prying tool to open up the casing and compressed air to remove accumulated dust and dirt.
Loose/Broken Hinge Screw
If the laptop screen will not stay lifted or is wiggly, disassemble the laptop starting from the battery and working inwards. Have screwdrivers and prying instruments on hand. Use the J00 Philips head bit screwdrivers to screw back any loose screw in the support of the hinges back to the laptop base or use hot glue (hot glue gun) to secure the hinge base to the laptop base. Allow hot glue to properly cool off and reassemble parts.
