my newly bought lenovo y400 top left speaker has a huge problem exist . when i play any movie or song , no sound was heard and sometimes some " pop , pop , pop " sound coming out from that particular speaker , i have checked with low volume - same! , other songs format - same! other movie format -same !. and i have checked with many different person .

To correct this , i had go to wisma CSA at petaling jaya section 13 which told by lenovo customer service assistance i called through phone . I told the service engineer about my problem and my laptop was kept one day for inspection , but on the 2nd day , the engineer called and tell me that he cant find any problem with the speaker , I'm very positive about the annoying sound because not only i myself hear it , my brother , my friends hear it too .

okay , now the crappy part , of course i'm mad hearing that the engineer told me that . For sure i warn him to check it properly , which he say he will do and call me back another time . Next , i waited for a weekend but no calls is received from the CSA engineer, so i called back . The news , my laptop speaker was told to have been changed . and i'm free to collect my laptop anytime . The next day , i went and collect my laptop . thinking that they have fix it , i just simply play a song and hear the sound, i did not hear it properly because i'm in a rush . When i'm back home and watch a movie on my laptop , the freaking annoying sound exist again . i was like what the h*** !

I suspected that they did not change my speaker but they told me that they have changed , I will call up lenovo tmr and go find the CSA company again . i will update on this post soon .

i have also disabled the microphone to test , the problem still appear to be the same . no sound and poping sound from top left speaker only . bottoms one are okay .
