The other day, I discovered that my Samsung RV511 wouldn't turn on. Any pressing on the power button resulted in absolutely nothing. I disassembled the laptop, and determined that it just needed a small power button tweaking. After fixing the power button, I made sure that the laptop still booted up. Everything came up fine. I then proceeded to power down the laptop and put everything back together. Once I got the main case back on, I powered it up and tested it again. Once again, everything was working. With the laptop still powered on, I snapped on the cover that goes over the RAM and hard drive. The computer suddenly stopped displaying anything on the screen. When I turn it on, it still makes all the normal noises of starting up, but nothing comes on the screen at all. I tried an external monitor, and it doesn't display anything either. I've tried switching the RAM to the other slot to no avail. I don't have any other RAM to test it with. If anybody can provide some insight into this, I would be very grateful. I just really hope that it is not the motherboard.
