Why a cracking sound comming from inside of LENOVO Y410 NEW

I bought a Lenovo y410 notebook last month. After i used it for a week, i've noticed that a cracking sound like 'Phot' always come out when my notebook is awaked from sleep mode for about 25/30 minutes. The sound appears to come out from front left speaker side next to hard disk. I went down to local lenovo service center but they can't explain nor give me a valid reason. They said that the notebook is working properly and no error was found. If anyone is using the same model, lenovo Y410 , or have encountered like mine, please share me how you solve or troubleshoot it. Thanks.

This happens to a lot of machines when they are coming out of the sleep mode. You don't have anything to worry about. It is just the sound devices coming back online from the sleep state.

Maybe you cracked it

Hi,

I've been working with computers for 25 years now and have never encountered something like this.
Do you have the right drivers for your soundcard installed? Does itneed updates? Or does your OS needs updates?

Good luck with it!
