High pitch noise in U310

2012-07-25, 1:52 AM

I just bought a Ideapad U310 with Core i5. The fan generates a high pitch noise even when I do nothing. Is it common for this computer? How to solve this problem?

I also have an u310 with the core i5. And unfortunatelly also the high pitched noise from the fan. Seems like this doesn't appear with all u310s? Has some send it in to the service for changing the fan?

Hi all,

 

thanks for posting and welcome to the community.

 

Sorry to hear about the issues you're facing but I'd like to check with you, When does this happen exactly? Do the fan occure when you are plugged in or battery only. Its hard to determined at this point what's causing this I'd like to work further with you on this issue.

 

Do let me know and I'll look into this further with you.

On another not when was the manucturing date of you machine. You sould to see it on the box thatthe machine came with.Its located on the sticker in which the barcode is located.

 

regards

Hi,

 

the high pitched noise starts, when also the fan does.  It doesn't matter whether the ultrabook is plugged in or in battery-mode. So the noise is constantly there from start till shutdown and audible even from a distance of 3m. As with all high pitched tones it is hard to localize it exactly but it's definitly on the left side quite at the edge somewhere between the shift and the power-button. So probably just another hint on the fan itself. The Mfg-Date is 2012/08/16

 

Thank you for being interested in solving this problem...

Hi,

 

if the fan generates this high pitch noise, its audio frequency will change with fan activity,

a higher fan rotation would produce higher pitch frequency, a lower fan RPM lower pitch frequency.
Can you confirm this behavior pattern?

Hello,

 

yes, this is the case. The noise is getting higher and more powerful when the fan is running faster. It's like a miniature jet plane rolling to the runway and then preparing for the take off.

Same problem with my U310 core i3

2012-11-26, 19:32 PM

I used to be able to stop the noise of the fan by lifting the lower left corner of the laptop using a thin memo pad or something (maybe like 2~3 cm in thickness). But all of a sudden this has stopped working and now the rhythmic high pitch noise is there constantly. Someone please help me fix this. I want to be able to take my laptop to the library without annoying other people.

So this would mean that this noise isn't the standard and just a few people have a not well working fan and there should be a solution to gain peace while working?...
