I dropped my laptop about a month ago. The computer works when I hook it up to an external monitor. The laptop screen itself is extremely dim. I was going to replace either the backlight or inverter myself. Just wondering though - if the problem is because I dropped my computer on its side (about a one foot drop on the side), is it more likely to be an inverter problem or a backlight problem? My suspicion is that its a backlight problem because of there was a mechanical shock...is this a fair assumption?
