I am azhar. I have an emachines e727 laptop. Previously I posted a post about my cd rom. I got a solution there. But i didnt try that. Ok now my problem is half solved automatically. That is previously my cd rom completely didnt work. But now when i plug my laptop before pressing the power button, i can see my cd rom works very good. I can find it in my computer, in device manager. But the problem is when i run my laptop on battery. I mean i press the power button with out plugging the charger and after windows loads it cannot find the cd rom. And the green light of the cd rom keeps glowing. That means i cannot run it on battery . So my question is that how can i fix this problem.
Any one helping will be appreciated
