I bought this notebook 10 days ago. The lcd screen was showing weird colours. The tech service ppl changed the inverter but i still have the same problem. They promised to change the lcd screen for me but I have to wait for the shipment. Lenovo should have adequate stock or else there is no point in having a service centre. Consumers cannot wait for a month or so for getting things serviced under warranty. I also do not like frequent visits to service centres and my new computer being opened and fiddled several times. I hope Lenovo looks into the matter. The Ser. ppl have informed me that the will replace the lcd panel next week. I am hoping for the best. Regarding the sound pls don't claim that the system comes with dolby and bass expander etc. The sound is crap and we can hardly hear the sound from 3 feet. Lenovo being a good company should rectify all these problems at the earliest to safeguard thier future in the notebook industry.
