hello. i just bought a used 501 Inspiron laptop for $30 because the monitor doesn't work. when I press the power button, i can hear the laptop boot for like a couple of seconds (nothing on the monitor tho) and then it shuts off. I can also hear the fan go off. Ive also noticed that the monitor is somewhat loose from one side (not much tho). What do you guys think it may be.....? thanks!
