Lenovo ideapad z500 whirring and vibrating

Hello, I've had my ideapad z500 for exactly 4 years last month, 4 years in which it worked perfectly (except for the brightness problem that seems to plague this model and had me recover the whole system evry time I accidentally lowered brightness)


It still works perfectly, but 3 days ago it suddenly started whirring and vibrating. The vibration seems even throughout the laptop, but the sound seems to come form the left side (again, I can't really tell).

First time it happened, I freaked out and force-shut it down (holding the power button). This made the whirring stop, but when I started it again, it resumed. Again, i stopped the machine and I started trying to unscrew everything I found (I mean, it's been 4 years, so I assume I had no warranty anyway), but I couldn't really open anything, so i put back the 9 screws. I mention this because, apparently, me turning it on all sides must've done something to it, because after starting the laptop again, there was no sound. The next days it worked just fine.

Today, however, it started again. I didn't close it immediately and I continued using it some 3 minutes (and except for the sound and vibration, everything was working perfectly), hoping that it will go away, but it didn't and I turned off the laptop.


Other details that might be important:

-while I normally use the laptop for cpu-intensive tasks, this occured in a week when I distinctively didn't do anything other than text editing and web browsing. The cpu often gets hot, but it was cool when the whirring started

-after installing win 10, the lenovo energy management stopped working properly (not that I ever used it for anything other than dust removal) so just the day before the whirring started I installed lenovo... advent?, thinking it had a dust removal function. It didn't seem to. Knowing how lenovo software seems to like to take absolute control of the laptop's brightness and fans, maybe it has something to do with it

-I normally use the laptop on a desk, with a laptop fan under it. The week it started, however, the laptop stayed tilted either in my hands or on a bed (properly ventilated, though) It also stayed a while in a crowded backpack. I suspect something might have gotten into the fan or the hd moved (I hear that when laptops whir it's one of these parts. No, I have no cds/dvds in it)



Now, what should I do to see whether it's the hd or the fan acting up, and what should I do in either situation?


I just started the laptop to record the whirring for you, seeing how this site allows for file uploads, but it isn't whirring again (it's properly seated on the table, in the conditions mentioned above) I do suspect it may do that again, though.


Thank you in advance!

Re: Lenovo ideapad z500 whirring and vibrating

Hi Whirringman,


Welcome to the Community Forums.


It would be ideal that you back up your files while there is opportunity to do so. Running diagnostics test or other similar test can provide informations to rule out possible points of failure. 


If the harddrive does proves to be ok then I would narrow down isolation to the fan system, that may be stress down due to usage so fan clean up and reapplication of thermal paste may be needed in the future. Those two parts are the only moving parts that can cause vibration specially if the fan's postion localized the whirring (not being heard over a headphone).


Since it is not being moved at the moment, it may be that it is currently on a good placement to isolate loose parts.


Update us how things go.
