Blocking Lenovo Y50-70 down for no reason

I have a portable y50 - 70 Lenovo to the old address of 1 year, still has 2 years of warranty. The problem is recently has started blocking down for no reason. Everything freezes, and about two seconds later it stops. In Event Viewer, it says critical error: Kernel-power (41). I updated all the drivers, I have the bios 3.03 version. The last time that this happened, that I heard a few crackles then my helmet had a noise for 2 seconds, after the laptop speakers has started buzzing too and it has not stopped, it just froze.

Please help, I can send info or files that might help.

PS. : I don't know if it's just a coincidence, but I think that stops started after I upgraded my bios to version V3.03

In the thread, you can find links to all versions

  • Re: Satellite A200 - shuts down for no reason

    I was walking where post and for a long time, allows to get help. My laptop Toshiba Satellite A200, 3.5 years
    * Problem: *.
    Previously, its used to stop by itself in the middle of the applications without any warning, the station used to be /: screen stops, no input from the keyboard or the touchpad, but the headlights before that mean the laptop is 'ON' remained * then I used to restart and thought it was a prob. OS or a problem of battery/charger (replaced both but not difference) and then this thing began to be more frequent and now the day has come, it won't switch.

    Current scenario: *.
    When I turn it on with the battery (without charger), turns on, screen lights up, it starts, power normal and at that time there if I plug into any compatible charger (I tried a bit), he died (the same way as mentioned in the "BOLD" letters above). If I restart or launch it otherwise while the charger is plugged in, it does not start but the headlights, the fan and the most important thing, to the processor (like the sound of sparks), this sound only sounded while I plug the charger.

    So, please help me out here, I don't know why he is not initialize

    Hey Buddy,

    This s really strange behavior, but I guess that this problem is related to hardware, I doubt it has something to do with the pre-installed software
    It seems to be a serious malfunction of equipment.

    In your case I contact an authorized service provider and ask the guys for help. In my opinion, it might be something wrong with the motherboard or the CPU itself but that s my personal opinion. So the easiest way is that you get in touch with the guys because they can give you an official response and make an accurate diagnosis. After that, you can decide whether you want to repair the laptop. ;)

  • For lenovo y50 cooling pad

    Hi, can someone suggest me a good block of cooling for lenovo y50

    Y50 fans look like they are in the same way they are in most laptops. They suck in air from the bottom and exhaust is placed on the sides or the back. In most cases on the rise, the desktop is sufficient to lower the temperatures of a few degrees. I myself did not use the fan in my block of cooling for centuries. It is more comfortable to use when he raised and tilted, and also the air flow is improved. And then I game not on my laptop for games more. When I got to the big finish cpu in my laptop (that the footer) and overclocked my GPU and memory, I removed the bottom cover of my Y580 and the fan on. The temperatures where there is a little lower, but I made it mainly to keep my HDD cooler because it gets really hot in this laptop under load.

  • ConcurrentHashMap obtain blocks of method for some reason any

    Hello

    The ConcurrentHashMap obtain blocks of method for some reason:
    -----
    private AbstractMap < String, SocketChannel > servers = new ConcurrentHashMap < String, SocketChannel > ();

    ' Public Sub sendPendingUser (UserPendingDTO dto, String serverId) {}
    [...]
    System.out.println ("Hello"); print hello
    SocketChannel ch = this.servers.get (serverId); <- BLOCKS
    System.out.println ("World"); never printed
    [...]
    }
    -----
    The method is called is called by an executable inside the class:
    -----
    final executable checkPendingUsersInDB = new Runnable() {}
    public void run() {}
    [...]
    sendPendingUser (dto, serverId);
    }
    };
    final ScheduledFuture <>? checkPendingUsersInDBHandle =
    scheduler.scheduleAtFixedRate (checkPendingUsersInDB, 1, 1, TimeUnit.SECONDS);
    -----
    If the sendPendingUser method is called by another thread (a Runnable) but I thought that it would not be a problem because I use a ConcurrentHashMap.
    * If I'm trying to replace this.servers.get (serverId); by this.sockets.get (test); I get the same error. This.Sockets is an another class in the same ConcurrentHashMap. Therefore, it is not specific to the servers map.*
    Thanks for any help.

    I doubt that it is a bug in the JAVA virtual machine. I also doubt that the code really "blocks" on this line, since a get() on a ConcurrentHashMap does not lock. You debug your code to make sure that it blocks actually on this line?

    It is difficult to say what may be the problem without seeing the rest of the code. It might be possible that this serverId is null, which would cause a NullPointerException in your task. You would never see this exception, because it is "swallowed" by the FutureTask, which cancels the task as a result of any Throwable.

  • Download a file should implement an option to open the file or save it - for some reason any now just downloading it straight to the download folder. Why? Problem with Firefox or something else?

    Download a file would normally bring up an option to open the file with the appropriate program or save it - for some reason any now just downloading it straight to the download folder. Why? Problem with Firefox or something else? It is very frustrating - sometimes, you want the first opened file so it can be discarded or stored in a different location.

    Find the type of file in the Firefox -> Options -> Applications Panel, open its menu drop-down and select 'ask '. To reset all the actions of download, delete the mimeTypes.rdf file in your Firefox profile folder (or rename the mimeTypes.rdf X if you want to save as a backup). The file will be regenerated with all types of files, restore the default actions.

    For more information, see application Panel - set how Firefox handles different file types and change what Firefox does when you click on or download a file .

  • Lenovo y50-70 WiFi reconnect all the time

    Hello world

    I use Lenovo y50-70 with processor i5 for two months. I'm just tired of trying to fix it myself this is why this post. My wi - fi is *. I upgraded my os to Windows 10 and had problem with 'limited connection', when you had to disconnect and reconnect it to work on the network. I tried many things, but lately I installed some new drivers and so far, this situation is back. But yet, there are some 'loss' connection, because when I try to play some mmo games, I get disconnected server, which I suppose is WiFi always had a problem with my laptop.

    EDIT: it's wifi card: broadcom 802.11ac bcm4352, drivers of 10.12.2015 - broadcom_wlan_7.35.338.0

    Can I please get any help? I can provide info on the plug or that, just let me know which... If all goes well there is a savior to do this, because I'm really tired of this question, and to be honest I have not expected that when I bought this machine

    HI, thx for the suggestion, but unfortunately it did not help. Maybe I'll clarify the situation. Internet high speed is very high, for example when I download a file, it goes up to 4/5 mbp/s, but the problem is with the stability of the connection. As I mentioned in my first post, it is impossible to play a multiplayer game, I get the broken link all the time in games such as Diablo 3, WoW, or now in the Division. I got all new drivers, my internet provider is UPC. There is no such problems, even with regard to the internet on the phone on the other laptop.

    Any other ideas please?

    Yes, but the problem as it involves a lot of troubleshooting steps. And given suggestions is one of the first check, you need to perform. Your problem is a limited number or abandon the connection. Check the compatibility of your router with your wireless card. The setting in the configuration of the card. Change the channel you are using. If you have 5 Ghz band try this out.

    I have this problem a few weeks ago and did what the technician of the isp is to just get the details of my modem (he is very interested to scribble information it receives) and declare that my router is to blame without a test at all. After that, he leaves and drop a service for an hour with his boss. After that, I discovered that the ISP is actually to reduce latency. There is actually nothing wrong at all in the installer than some hideous moving from my ISP.
