This problem happened to my friend. So many time it is serviced. But the problem persist . Only the replacement of this laptop will resolve the problem . Please go through video.
The problem is It providing a long horrible beep sound on start up.
Lenovo Providing products with low quality . The main problem is that i have suggested this laptop. After this problem i got a lesson. I never suggest this lenovo or ibm products to any of my friends.
