From my friend who had a Lenovo notebook, I got the feedback it is working fine. So I decided to buy a Lenovo laptop. I got from one from the dealer and hopefully it was working fine initially. But after days went by it started giving many problems.
On booting the screen would be completely blank. After getting it repaired again the charger was damaged. I had to get a new one. I thought the problems are over, but again after booting the screen will be lighted, but there was no display on the screen.
Like this problems started one after another and finally I decided to sell it and buy another company. Some of my friends told they also had similar fate with Lenovo. I think I will never go for Lenovo in future.
