Sorry If this is in the wrong place but I couldn't find a board for IdeaPad 700. I've had this laptop for a decent while (almost a year) and although it hasn't really bothered me much in the past, it's really starting to bother me now as I'm now usually in an area with more people (libraries, lecture theatres etc.). Everytime I start up my laptop, I can hear a constant crackling sound (which would continue until I shut down the laptop but would continue again right as I turned it back on) and sometimes a beep or two but mainly from underneath my laptop where the fans are located or where my right speakers are located. I'm not sure if it is a sound card issue or a driver issue as I don't hear anything like that through my headphones and the sound is perfect, however, the crackling noise still continues on my laptop itself. When I play music or watch any video through my speakers, the sound from the left speaker seems fine but the sound from the right speakers sometimes becomes distorted and you can hear like a quiet mumbling sound of the music or video underneath. I've also noticed that when I am using my scroll wheel on my mouse or scrolling using my touch pad, the crackling gets louder but as soon as I stop scrolling, it goes back to its "normal" crackling sound.
I'm not sure if this is enough information but I really have no other idea of how to accurately describe the sound. I've also tried changing driver versions but it did not seem to work or do anything really. I haven't tried doing a format yet as I'm quite busy and I pretty much need to use my laptop 24/7.
Any help is greatly appreciated,

Hi VinceZent ,
Welcome to the Community Forums.
Try booting on the BIOS using the Novo key (item6 page6) to turn on and press a bit on the scrolling on the touchpad.
Check if same sound appears booting on another live media is available.
Reviewing the placement of the touchpad to the systemfan and right speakers , I think mechanically is an issue with the fan. Pressure can be done by the touchpad passing it to the fan and underlying structure including the speakers as ,maybe just a cable on the wrong place since expected that it would be silent on this model.
You don't have to change on the softwares but I would encourage you giving technical support a call for in warranty service and option that you can decide on.
Hope this help answer your query.
Update us how things go.

I'll give that a shot thanks. Also, I don't really think it makes sense for the intense crackling sound to occur when scrolling using my mouse which is wireless? Scrolling on both the touch pad and the wireless mouse causes the same effect but just using the touch pad to move the cursor around does not cause the intense crackling to occur.
Edit: I tried starting up using the Novo key and went in to the Bios and I noticed that the crackling sound didn't occur at all during the whole duration as I was there for about 10-15 minutes but once I left, the crackling sound occurred again.
