[That's the problem, I tried to search for a solution but nothing. Maybe I should change completely my laptop as most of its parts don't work. I recently changed my battery, my Bluetooth don't work, my wifi stops working suddenly and now my CD drive stops burning. The warranty is still valid but when got to the local distributor and service agency they told me that these repairs do not form part of it and that i should pay. The price to repair it, makes 1/3 its buying price as new.
