I had lenovo 3000 Y 1000, which is now of no use as it had got multiple problem in it .firstly I had to face battery problem but that time ut was in its warrenty period so I had no problem .Then few time later I had to face its software problem, then later finally its mother board corrupted and my laptop become of no use, as the money I had to invest in its repair all the time it fail, I could have brought another laptop of same price .
