Y40-70 fans not working

I sent my computer in for a repair because of a faulty wifi card. A few days ago, I got it back, but now the fans aren't working at all. The temperature is constantly at around 70°C. I've already tried updating the bios, and even doing a factory reset, but the problem still persists. I have to use an external laptop cooler for it to be usable. I'm so tired of dealing with the problems with this laptop at this point.

Hi MustafaHashmi,
Welcome to Lenovo Community!
As per the query we understood that you are facing issue with touchpad not working in your Lenovo Y40-70 laptop.

    Hi,
    Any one have this issue?
    HP ProBook 5220m (Bios Version F50) Fan not working with battery power but work fine with adapter plugged in.
    This issue was found in my replacement motherboard. the original mother do not have this issue.
    The origianl mother to be replace is due to can't power on after a power failure recovery. I believe was due to power surge killed the motherboard's power controller circuitry.
    Appreciate any one can provide clue for resolving the problem.
    I have tried to install speedfan to try my luck, but it can't any fan in the application to configure. (Bios Version F50)

  • Horrible fps problems, fans not working

    Hi,
    Whenever I play League of Legends on my 15 inch retina macbook pro, the game starts out smoothly with a consistent 60 fps.  However, after a certain period of time, the fps severely drops to about 5.  It never used to do this, but now it happens consistently.  Also, the fans have not turned on in months; they used to always be on whenever I played League, but they seem to never turn on anymore.  Could the fps problem be related to the fan not working?  Please help, and thanks! 

    Sargeraspa,
    Lenovo G770 has ThinkVantage System Update? I thought that is suppose to be for ThinkPad system only?
    Go to the link below and Select Win 7.

    Then update the BIOS and Energy Management driver.

  • 2540p fan not working

    Hi,I bougth netbook hp 2540p windows 7 instaled,and have a problem with cooling fan.The fan not working on the battery ,working connected to power adapter all the time.have you any suggestions how to fix it.thx

    Windows 7 or Windows 8? You are likely set to passive cooling in power management while on battery which means the laptop will do almost anything rather than kick on the fan while on battery. It will slow the processor instead. If you shift to active cooling your battery will get eaten up very fast. In short, I think your system is probably fine and messing with it does not make any sense. However, here is some more information on passive vs. active cooling:

  • Error 90B - Fan not working properly?

    Hello, this is my first time here so please excuse me if I posted this in the wrong section.
    First, general specs:
    HP Pavilion dv6 Notebook PC
    Windows 7 Home Premium 64-Bit
    BIOS:  InsydeH20 Version CCB.03.61.09F.21
    Processor:  AMD A6-3400M APU w/Radeon HD (4 cpus ~1.4GHz)
    6g RAM
    (If anything else is needed to help me ask, and I shall post it)
    Last week I received an error 90B for my laptop's cooling fan.  I was playing Guild Wars 2 and in the middle of playing my laptop shut down suddenly.  When I turned it back on it presented the error I'm asking about.  The thing is, the system wasn't overheating in the slightest and the fan was working just fine before it shut down.  I've tried many fixes proposed on HP's website and from a couple of friends:
    -Compressed air blown into the vents
    -System restore to a point where the fan worked
    -Hard reset
    -BIOS update
    None of those proposed fixes worked.  However, I did find something that fixed it...for about ten minutes.  I fiddled with the Catalyst Control Center and set my CPU power back to its default 1400 MHz, and I shut down my system.  After I restarted it I miraculously didn't get the 90b error!  You could imagine how happy I was.  I shut it down one more time to see if the error was truly fixed, but lo and behold it showed up again.
    The only change that could have caused the issue was me downloading a program called SpeedFan to monitor my system's temperature (I did NOT (I repeat, DID NOT) change any settings using the program - I purely used it to monitor the temperature.)
    I cannot afford to have a repairman replace or look at my laptop as of now, we have bills to pay and food to get, and I absolutely NEED this computer to function.  I have work to do, and classes to sign up for, and we have no public computers for miles.  Please help me!

    Not every fan error is a heat error. There is a sensor that detects a bearing that is wearing out or spinning that is out of round. You can sometimes limp it along for 6 months before the fan absolutely has to be replaced. When it does you will not be able to get past the error. 

  • PAvilion dv6, fan not working correctly?

    Was on my laptop, it shut down randomly, notification popped up saying fan was not working correctly. Is there a way to fix this? Or will it have to be sent away?

    Try a can of compressed air in the reverse direction of the normal air flow. You may just have a massive amount of dust on the inside of the heatsink near the fan blades.
    Here is a youtube video and about 15min in you can see the fan clearly:

  • System fan not working properly

    i have a hp 15 notebook 15-r004ne  laptop and when i turn it on, it states the fan is not working correctly, then shuts down after 15 seconds or continues to windows if you press enter. I dont know what to do now please i need help .
    Answers will be appriciated.
                                                           Thank You.

    The fan may simply be clogged with dust, pet hair,etc. Pick up a can of compressed air and use it to blow out all vents really well.
    If the problem continues try a hard reset.Disconnect all external devices first.
    1-remove power cord and battery
    2-press power button for 30 seconds
    3-reinstall only power cord for first startup.
    4-power on

  • Cooling Fan Not Working Properly

    Hello,
    i have an HP Pavilion g7 laptop and when i turn it on, it states the fan is not working correctly, then shuts down after 15 seconds or continues to windows if you press enter.  I cleaned all the air vent with compressed air and still get same mesage when i power up.  The computer seems to work fine otherwise, but sometimes the fan will run at rather a high speed all night even when it is supposed to be "asleep" with the cover closed. I have to make it hibernate to ensure that it does not run all night like that.  Do I need to replace the fan and if so, how?
    Thank you!
    Rick

    Yeah im having the same problem with the same laptop. Im kinda pissed about this because the first month i owned this laptop, that same fan broke and i had to send in into HP to be replaced. So now here we are again with the same part broken.
    My friend also bought the same laptop at the same time as me and his fan also broke. So clearly this is a defective part.  Not only that but they broke my keyboard during the fan replacement.
    So HP are you actually going to do anything about this because i was just on your FB page and repeatedly got ignored by the chick TINA who runs the page or whatever.
    So im not too happy at this point, so whats gonna be done about this HP?

  • Cooling fan not working...????

    when i m turn on my laptop...
    there is message display that cooling fan is not working correctly..???
    & shut down after 15 sec now what is the problem is happen???

    We need the model number of the laptop to give detailed help. One thing you can try is to remove the battery and AC adapter. Bent out a paperclip and stick it in the fan grille to hold the blades. Blow in compressed air. Now put the AC adapter in and start up. Tap F10 to enter BIOS. As you leave reset BIOS to default. This may remove the message. If not the fan needs to be replaced.
