[Resolved]  Sony / Laptop — Sound and battery problems in new Sony laptop

Address:

South 24 Parganas, West Bengal

I have purchased a new Sony laptop of model no. VPCEA16FG/B, Serial No. S[protected]i vide invoice no. SPL/TDG/061/10-11 of SPL Infotech, 53/5 Central Road, Jadavpur, Kolkata 700032. From the very beginning, several problems were found.
1) Display: There were two positions on the screen waving continuously.
2) Sound: The worst sound quality I have ever heard in a laptop. When the sound level is increased to 50 - 60%, the sound cracks.
3) Battery: Sony claims that the battery life extends at least 2 hours after full charge. In real case the battery life decreases below 50% within 30 minutes. Its really unfortunate.

I have contacted the sony center at 32 Hazra Road, Kolkata 700029 and they checked the problems but they denied to give me a written document. They have solved the first problem but they claim that they couldn't do for other two problems. They refuse to give a replacement.
