That is cheap! the SW is a really good notebook too! I bought one used from Ebay a year or so ago, and it has been excellent. It's slightly better than my G73jh, except it doesn't have the blue led glowing under the screen. Otherwise, the Nvidia card runs cool and fast. I also was able to add a new battery to it.
Not coming on does sound like a power problem of some sort. You'll have to get into your hands and try some things first. Check the power jack for a good physical connection. That's a trouble spot. Make sure you have a good charger/power pack, or get a replacement. Good Luck!!
