ok, as i experienced. IBM lenovo service is really bad compare with dell and hp. Usually when i call up Dell or Hp redarding the waranty claim for the faulty part, they will send the engineer to my company and replace the broken parts immediately or they will give me a loan unit that means  they will take back the faulty equipment and i will have that unit aka replacement.

There is a case where my user claim that his 1 months years old IBM leenovo pc's PSU failed to operate so i called Leenovo to claim a new PSU..and the result is the engineer told me they cant replace it because it is due to our company unstable electric supply and many nonsence excuses. Damn, this is so Fxxk because whenever i call up DELL or HP regarding the warratny like motherboard, monitor, hardware and PSU and they never say No to the customer. So we came out with a decision that time, we won't buy any IBM leenovo unit after that.

And i would say, a service center without a customer oriented service wont win the heart of the customer. If compre with other company especially Dell, Leenovo service really bad.   

first time i hear this about lenovo lucky i din buy it
