Use an old brace or get one for $1.50 at the hardware store and secure it onto the laptop using the strips. Voila, the screen now stays up!!
The hinges on my Inspiron 300m are worn out. Being cheap and not wanting to fork out > $100 for new hinges I came up with this simple workaround with velcro strips and a brace- mightn't look the best but it works!
Step 1: Attach velcro strips
Get some velcro strips and attach to the bottom of the laptop and the back of the screen. In retrospect I would probably go for wider strips than I have now.
