As stated in the title, my laptop has been making this sound occasionally and I’m not sure what it is. I have a thinkpad t14s. It started a few months ago and i thought it was a one off thing, i don’t have a disc drive but it occurs around the fan area maybe towards the center. I kind of just turned it off for a while and it stopped when i tried again. But the past few weeks it’s been more frequent. Attached is a short clip, but it’s not even at its worst. I just wanted to post and see if anyone has any idea what this is - i plan on taking it in to get looked at. I was thinking fan but a friend said maybe hard disk drive. TIA!
