Sir, I have given my note book in hp service center for case of
adapter and hard disk.
They don't cover the problem of hard disk by saying that CT No. and
Part No. both are missing. But its not my fault and away of my
knowledge because how one can check the hard disk when he buy it. So
please give me solution.

Model no.-CQ 610 / WB279PA
Serial no.- CNU9464M1B

My contact no. 09889334513
Thanks.
