Lenovo laptop not working properly

Respected Sir,

I have LENOVO Y500 laptop purchased on 5-jan-2008. I have extended its

warranty to 2011.

Its Serial No. is 7761-47Q-MA-7Z5YH

I am facing problem with this laptop from last 1 year. From last year

i am visiting its service center to get it repaired.

I have got repaired its OPTICAL DRIVE 9 times. I have also face

problem with its MOTHERBOARD and HARD DISK.

Lenovo has failed to provide me a good solution.

Last month i send a legal notice to company. After repairing the

laptop they asked me to to sign on a letter which says that i am fully

satisfied with the product but i refused to do so. Because i know that

this is not a permanent solution. And now they have replied to my

notice saying that there is no problem from our end.

Laptop is still not working.

Please help me to resolve my problem.
