Y570 - fn + f5 does not and the fan touch button does not

Hello

Title says it all, that suddenly when I press fn + f5, I can not turn on wifi or bluetooth - nothing happens. Same thing with the fan control button - nothing has happened when I press on it.

I reinstalled without success - Manager energy

Hardware for the wifi switch is on

WiFi adapter in windows settings is turn on but not connected.

I reinstalled the drivers wifi - without success.

What could cause the problem?

I did restore the proven system - does not

BUT

the solution was found just a moment ago.

I found this topic

http://forums.Lenovo.com/T5/IdeaPad-Y-U-V-Z-and-P-series/y570-power-thermal-management-and-theatre-o...

I did as he said - off computer pluged the battery for 5 minutes and there we will - it works now!

But it's sort of a weird, why it works... but as long as it works, I'm happy.

Thanks for the replies

    [Moved from the community centre of Participation]

    Fan errors are usually hardware problems. There is a fan in the case including detector does not detect that it is available or spinning. This could be a problem with the real fan or the fan sensor.

    Does this have to do with? Are you talking about an error that is displayed by a Windows machine? If so, what version of Windows? When the error take? At boot time? Before or after that Windows allows you to open a session? When you provide no details, it is almost impossible for anyone to help.

    Hello

    On some machines, the pilot for 11 series IMEI has been known to cause that kind of question of the judgment, so it may be worth trying an earlier version.

    Try to use the following method to see if you can install an earlier version of the driver IMEI.

    Download driver IMEI on the link below and save it in your downloads folder.

    http://ftp.HP.com/pub/SoftPaq/sp66001-66500/sp66228.exe

    Disable your wireless card (should be f12 ).

    Open your download folder and run the installer - it warns you that it is an earlier version, but simply continue.

    When finished, restart the laptop.

    If the computer shuts down correctly, turn on your wireless adapter and use the utility on the following link to prevent Windows 10 to update automatically the driver IMEI again.

  • Process creates the CPU to overheat and the Fans to run like crazy:

    I am ripping DVDs on different Macbook cradle fully aware that it's requiring treatment.

    The 2011 with 16 GB of ram and hard disk SSD, the process runs on 330% of the processor, blasting the ability and heat

    revolves around 100 c/213 F.

    Interesting enough the same process on 2 late Mo Pro 2008 with less ram do not overheat in the extraction process. The program are identical on all the Pros of 3 MB. The processes are the same, but on the old MBpros the processor load is between 130-150% up to more heating is not that great a problem.

    But the MBPro of 2011 with top material tearing overheating of the processor and fans running at full speed.

    I noticed that too much work with other programs or is running only a few programs at the same time seem to heat from the processor and the fans make some noise + cpu run hot with my MBpro 2011 and El Capitan.

    It is possible to restrict a program that use a large part of the resources to avoid overheating?

    Other solutions?

    Well a Late 2008 Macbook Pro has a intel core 2 duo, so the max he could run is 200% (2 CPUs time 100%) if the application can do enough on 2 processors in parallel.

    Your 2011 Macbook Pro has very probably a 4 core CPU intel i7 with hyper-threading.  If an application can use hyper-fils, there is a potential of 800% max.  The 330% could just be that the DVD cannot keep up with the CPU, so it does not hit its maximum potential because of the famine of data.

    I don't know if the speed of the DVD drive in 2008 was the same as the 2011.  If the 2011 is able to read data more quickly than the 2008, then it can provide given the CPU faster, keep the much busier CPU so it can consume more power, and more power consumption more than the heat generated.

    MacBook pro 2011 ends a DVD in less time than the 2008?

    Basically, you are trying to compare 'Granny Smith' vs 'Golden Delicious' apples and expects the same taste.

    Regarding the other programs, put this SSD in your Macbook Pro means that any code or data that the application needs to get the disc are convinced order or magnitude faster, so that the application did not slow the CPU and keep crank, causing the CPU to keep them busy and thus attract more power, which is converted into heat causing fans to run.

    It is also possible that your SSD generates more heat.  Solid State does not always mean longer running costs.  Much would depend on the brand and the model of the SSD and it is the power profile, and it draws more power for writing vs readings, and how much nature more expensive power you're done.

    Information point.  I put an SSD in my 2009 27 "iMac and it works more hot because my iMac can do more in less time.  I put an SSD in my Macbook Pro 2011 and if I ask him to do a lot of work, like backups, it starts its fans, as the SSD is always quick to provide data for backup, there is no waiting for the discs, leaving the lower idle CPU.

  • Satellite Pro S500 - 11 c is suspended and the fan runs at full

    Hi people,

    I am experiancing a problem with my Satellite Pro S500 - 11 c where close unexpectedly, it crashes and the fan runs at full speed. Discount to zero is my only option and this resulted in the windows having to retrieve a few times so I'm fearing one requiring a major reconstruction after a deadlock of the future. Until now this issue has occurred only when you use a wireless USB mobile of 3G or internet teathering via USB with my iphone 3G. Using another USB port did not help.

    If someone has encountered this problem and have a fix? No help from Toshiba?

    Best regards

    Hmmmm... What to say. Problem is that you use third party hardware and software and some conflicts are possible. The question is: who can help you with this?
    In general you should talk to your ISP provider at first to see what they will say about all this.

  • G7-2017us Pavilion: laptop computer is hot and the fan is noisy

    I have windows 7. 64 bit. I noticed that the laptop gets very hot and the fan makes noise. Try to solve this problem I went the HPSA. It shows that I have no update necessary; However when I go to the HP site and I ask him to identify my system it shows a lot of updates pending. This is why I need help with 2 questions, one the heat generated and the second on the updates. I also checked, and it shows that I have the latest version of the Support Assistant. The updates are all from 2016 and 2 refer to the BIOS.

    I'm not well informed on the issues, any help will be appreciated

    The update of the BIOS F.26 is important because of security concerns. The change log States:

    'Provides security improved for UEFI EDK2

    HP strongly recommends transition immediately to this BIOS update. »

    It will not hurt to delete the sp66805 folder. I suggested it because it confuses you with the process of downloading/installation asking you to replace it.
