That sharp object SHOULD NOT be metallic or else you say good bye to your dear net book. I did the same. First I inserted a SD card into it and wanted to see the information in the card. I found it just got frozzen. It stopped to function. I even tried to switch it off by pressing power button for long time but it was not even switching off. Then I took a metallic pin and pressed the reset button. That's all. Now when I press power button only the green powen on indicator glows and that's all. It was only when I read the user's guide, I saw there was written NON METALLIC SHARP OBJECT" to be used to reset the computer. So that's all,my friends.
Anyways, if somebody could give me tips as to how to fix it up,I would really appreciate it.
