loud sound when asleep

[jiato]

Hello,

When I am using my Surface Pro, I can hear a slight fan noise. I expected this and don't mind it at all. When I put my device to sleep, though, something inside starts whirring louder than my old laptop. It lasts for 15-20 minutes at a time. It sounds like the fans, but it is much louder.

Has anyone else encountered this yet? Do you have any idea what is going on? I feel like this is killing my battery life while the device is supposed to be asleep.

Any help would be much appreciated. Thanks.

Doesn't sound normal.. Have you changed any of the power plans?

i have not changed anything. The weird part is that as soon as I wake the Pro back up, the noise goes away.
