but i sorry to say i am fully frustated from lenovo Product and services.
Within 7 Months :

2 times changes Motherboard.
and now Service Center told me that HDD is faulty and need to replace it.
TKT No. 30008437

I am asking to you sir: In case if you purchase any thing from your salary, When your salary is small and within 2 months its giving you problem then what will you do?

My Laptop warrenty is 2 year extented as per diwali offer.
In case If i not borrowed this services then i have to pay 3 times money to lenovo as per its cost...( for motherboard and HDD )

I purchsed this laptop for my bright future and practices of networking tools but still i have not installed any kind of software on it.
i never recommend My Friend, company friend, Family member.

After 5 days of my logged complaint no one called me from custoer care center..#
Is there any SLA of Service Request.

I am ready to pay extera money if you offer me another latop with higher series.
