I bought Toshiba Satellite L505-10W a few months ago. It was totally working fine until now. Today when i came back from college, i turned on my laptop and it showed a black screen related to set up and reboot. I put in the recovery CD that i had got with the laptop and tried to restart. It restarted but the keyboard stopped working. I unplugged the battery and tried restarting again, the lights were on even though the screen was completely black. I tried the same procedure over again(unplugged the battery). ever since then the laptop wont turn on at all. But when I plug in the power supply, I do see a green light but nothing happens when I turn the on/button. Can somebody suggest me what exactly did go wrong with my laptop and how can i fix it? I am a student. I had all my data in the laptop. I cant just lose it like that. Help needed urgently.
