i got one G470 for my bro last May during PC Fair.

last week the screen got few black spots and looks like black oil leaking inside.

sent to lenovo sc, they said its due to user faulty. no warranty for that.
WTH?? it's only 3 mths old and with no user negligence, i wonder how it could become like that.

my bro confirmed he didn't drop it or whatsoever, but still lenovo said its due to user faulty. can this be brought to consumers claim tribunal?

any advice?
