Lenovo Thinkpad Edge E420 High Frequency/High Pitch Noise

Hi, I just got a thinkpad edge e420 and I have noticed a high frequency/high pitch noise as well as a whirring sort of noise (sometimes, might just be hard drive tho). It is quite soft and I can only really hear it when I am in my bed at night with the laptop. It can get quite annoying. I have heard of similar problems like this when I did a search but no clear solution. 


Where exactly is the noise coming from?

Is there a solution?

Is this normal for all e420 or is it just a very common problem that may require warranty service?

Re: Lenovo Thinkpad Edge E420 High Frequency/High Pitch Noise

it is not really a problem, there is no real solution to this whining problem, as per the discussion we had on whirlpool.
