Address:

Udupi, Karnataka

service tag:HLYW7BS

i bought the dell xps-L501x on 2 jan 2011 online directly from
dell.since the day i got the it i facing many problems with the
product.
1.On the very first day of my order delivery i.e. on 14 jan 2011 i
found out that there is a red spot on my laptop lcd screen,for that my
lcd screen was replaced.
2.after some days o[censored]se my USB port stopped functioning,for that
mother board was replaced.
3.since the problem was not fixed,again the daughter board was replaced.
4.now i found out that my laptop does not have physical wi-fi adaptor which was resolved temporarily.
5.I also have internal problems with my laptop(like frequent windows crash etc.)

although my warranty has been expired now but the problems with dell components continues,

***6.laptop battery doesn't charge to full capacity, initially starting from 100% now its charging limit reduced to 40% only, after which it stop charging any further.

initially i thought that this is a temporary problem but now i realize its not.

since the problem started when the system was in warranty period,i hope Consumer Forum would take some action regarding the same.
