I bought used ASUS G1S before 3 weeks and it was working fine first 7, 8 days. Next day ,when i tried to turn it on, Display didnt working. I left it to turn on and it turned on just fine without display. I tried to Plug in Extern monitor, Take out RAM and puting it back in different orders, Start with AC power, without AC, with battery without, I tried every possible combination and didnt work. When i hand it in service i saw that he turn it on some how without AC and with extern monitor, several times he take out RAM and put it back. I have NVidia GeForce 9800M GT.
