Why does my screen flicker to black at certain angles?
Problem: I just noticed this evening that when closing my laptop, the screen turns black when it reaches a 50-degree angle.
Background: I have a Macbook Core2 Duo that I bought toward the end of 2007. Over the years I've replaced several parts, the latest being the top case when I busted the cable during some maintenance. I know my laptop is old and at some point it's just not worth fixing any more, but I'm currently a Peace Corps volunteer with a year and a half to go and I'd really prefer it if this laptop survives my service.
Theory: I'm guessing a cable is fraying (I have disassembled this to fix the iSight cable twice so I know how twisty the wires get in there). If this is the case then I'm stuck since there's no way I can find a new cable where I am.
Other comments: I have a USB modem to get internet access. The program that must be running in order to go online uses nearly 100% CPU, so the CPU temp is between 180 and 190 degrees F. I've taken to propping the rear of my laptop on a book or roll of tape to maintain some air circulation. Although the book contacts the bottom case, I'm wondering if this puts a strain on the laptop in the hinge area. I don't have any alternative ideas for this, though, because I have to use this ridiculous program with this modem.
Any help, comments, suggestions, &c. are appreciated (even if it's to say I should just suck it up and get a new computer; leaving this Mac would bum me out).
Is this a good question?
