Hi all, I have the lenovo y510p SLI 750m version and recently (2-3 days ago) my cpu fan on the left side of the laptop stopped working with the dust removal tool. I removed the lid and I can see both fans spinning just fine, however only the right one actually performs the dust removal when prompted. The other one stays queit and I don't feel any air pushed out of the left side. I can feel it on the right like normal though. Any ideas on how to fix this?

Hi sifuraga ,
You can initially power drain the system , turning it off removing the ac adapter and battery then pressing down the power button for 12 seconds . Start the machine using the Novo button (page 82) to launch the Novo menu for BIOS set up and set BIOS defaults f9 save and exit F10. Check the BIOS version.
Check how it goes else proceed with uninstalling and fresh installing the Lenovo power mangement tool . Restart and recheck .
Update us how things go.

I've reset the BIOS to default using the F9 key, but to no avail. Then I attempted to uninstall and reinstall the Lenovo Energy Management software like you instructed me to, it still won't operate correctly. Could it be perhaps dust blocking the fan? Or could the fan be broken? Albeit I've have the laptop for about 4 years now and I've never done an inside cleaning because I'm afraid to open the laptop up.

Hi sifuraga ,
Since this issue just happened 2-3 days ago , if configuration may have been changed , check if system restore would help as it would allow you to jump back to previous date or restore point.
In terms of internal maintainance such as fan cleaning , if you don't have tools or skill to perform , best that you have it check with a service center as they may allow be able to test fan integrity along the way. As it spins on both fan further boost on spin maybe an indication for mechanical failure on one of the fan. While it is off , you can try spin it with your finger and compare the feel on both fans . Using canned air to clean would be handy.
Herewith is the hardware manual for reference .

Welp, looks like the system restore was a bust. I don't know about taking the machine to a specialist because I have no idea about how the pricing works so I'm going to try and open it for myself.

Hi sifuraga ,
Take time to review the manual guide but again if you really would like to isolate hardware issue from the software , a factory reset would do it but that means that you would lose everything and would need to start fresh from out out of the box experience.
Update us what works best for you .

I apologize for this very late reply but I have solved my issue.
Back ground Info and details of my issue:
I've had this laptop since release date back in 2013 and I've used it intensely for gaming and web browsing, meaning everyday, 4-8 hours a day. Last week it got to the point where idle temperatures of the CPU was reaching 60-65C and I had enough, the warranty was already expired and I had a hunch in the back of my head the reason why I couldn't feel air being blown out of the exhausts. I only realised this after the right exhaust (the ultra bay port that housed the 2nd 750m graphics card) stoppped blowing air and it just clicked in my mind. Dust.
I completely dismantled the laptop, blew out the dust with compressed air, got rid of the old thermal paste and reapplied a new one. As soon as I put it back together, I was hoping that I didn't mess it up and that it would boot up, and thankfully, it did. I noticed a huge difference right away during boot time, it took 20 seconds compared to pre-cleaning, it took almost 1 minute and 30 seconds. My idle temps are now 40C instead of the horrifying 65C. I can now play video games and browse the web again without worrying about the laptop throttling or overheating during an intense session. It was as if I had gotten a brand new laptop. The best part, I COULD FEEL THE AIR PUSHING OUT OF BOTH EXHAUSTS.
I cleaned the dust and reapplied thermal paste.
For you guys who are reading this and are having the same issues, please understand that taking apart the laptop will VOID YOUR WARRANTY if you still have warranty that is.
If you're planning on doing this, get someone who knows what they're doing. One missed step and you can say good bye to your laptop.

Hi sifuraga ,
Good to know that all is ok after proper cleaning as part of usual maintainance.
As previously suggested :
"In terms of internal maintainance such as fan cleaning , if you don't have tools or skill to perform , best that you have it check with a service center as they may allow be able to test fan integrity along the way. As it spins on both fan further boost on spin maybe an indication for mechanical failure on one of the fan. While it is off , you can try spin it with your finger and compare the feel on both fans . Using canned air to clean would be handy. "
It would not void any warranty for as there is no parts damaged along the process or due to wrong steps , as same reason why the guide are provided for users thru the hardware manual and service taining. If a user are not confident on any steps , getting proffesional help is advised.
Further discussion here for CRU's and FRU's against warranty agreement.
It can also be regional specially if you encounter a warranty sticker sp best to call in technical support for confirmation.
Best luck to you on all your endeavors.
