Noise issues with Edge E420

[ Edited ]

I'm having some issues with noise from my new Edge E420 laptop. So far everything's running smoothly, no slowdown or performance issues, but the noise coming out of the machine is bothersome. It happens when I'm doing a task, such as browsing the internet, but it also happens when the computer is sitting idle. I don't know what precisely is making the noise, but I suspect it's either the CPU or hard drive. The fan does make slight noise that is sort of a constant whir, but this other noise is intermittent (although frequent) and sounds like the typical computer "thinking/processing" noise but not high pitched. I had some earlier troubles with noise that was high pitched, which I rectified by turning off the CPU power management in the BIOS utility. Anyone else experience this noise issue before? If it was only every once in a while I could live with it, but the noise is constant. It's really driving me nuts!

Re: Noise issues with Edge E420

hey candide,

could you use this hardware maintenance manual >> http://support.lenovo.com/en_US/guides-and-manuals/detail.page?DocID=UM006567

and open your unit and clean the interior, especially the fan area and the vent near it.

btw, is your E420's bios at version 1.16/1.07? if it isn't, do go to http://support.lenovo.com and update.

Re: Noise issues with Edge E420

Is it a chattering or clicking noise?

I assume you don't have an SSD. Can you try defragmenting the drive?
