T440s lost Bluetooth after having installed the latest updated via the Lenovo system update

Hi everyone, my setup - Windows 8.1, Intel Dual Band Wireless AC 7260 with Bluetooth built-in.

After the installation of the last packet of Intel's Bluetooth (via the Lenovo system update), I lost Bluetooth constantly.

-J' I tried to uninstall the update of the driver, nothing has changed.

-J' tried to restore through Windows Restore Point (I did a fresh restore point before you install these updates,) without success...

I noticed that:

-When this happened, the fingerprint reader to are featured strange - there is no if light (with green light) initially, Windows, and Windows was asking me a password instead of the fingerprint.

-In the Device Manager. Bluetooth category disappeared (I was there before the upgrade - for sure.). but I saw a new unrecognized device whose name ends with something like "(de l'énumération n'a pas pu) '-this could probably be the Bluetooth card."

-L' tray for Bluetooth icon disappeared.

-The Bluetooth system option submenu and its devices in the Windows settings disappeared (and it was here before).

-Looking for Bluetooth in Windows 8.1 returned property (with Win + W hotkey) framework "set up Bluetooth devices" or similar, but when I clicked it, it couldn't access this option - just took me to the main configuration screen.

I had to do a restore of the system using Linux (thankfully made a full HD image backup of the HDD and SSD using Clonezilla readers - that was the only way to fix this-instead of complete reinstallation of Windows).

The only driver that works for me is the Intel version 3.1.1307.364 issued on August 1, 2013.

-Anyone else had similar problems?

Apart from this, the Bluetooth disconnects always happen: see http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T440s-major-WiFi-and-Bluetooth-instability/...

Can someone give me some advice please?

I need help with this.

I found a solution to this problem.

Apparently, installing bluetooth driver through update system does not install it properly.

So I downloaded the latest driver of Lenovo driver download page, and instead run autorun.exe, I sailed to 64-bit dir and then run the installation program.

Everything works fine now.

  • Application does not not after having installed the wrong version

    Hi all...

    I wrote a simple application that sends an e-mail message and tested many times up to now. Never had any problems. I have make changes every time, I generate for BB OS 4.5.0, version 4.6.0 5.0.0 and 6.0.0. Yesterday evening, by mistake, I installed 6.0.0 version of the application on my BB 4.5.0. When I run the application, it gave me an error. I realized the error and uninstalled immediately. But later, even after you have installed the correct version, the application never worked (4.5.0). By clicking on the 'Send' button simply does nothing (it allows to send an e-mail earlier). The same application with the corresponding versions working on my BBs 4.6.0 and 6.0.0 without any problem. The 4.5.0 version works very well with the Simulator.

    Can someone please suggest a way I can get my 4.5.0 version works on the phone again?

    Thank you very much in advance!

  • Problems with sound after you install the operating system

    I have a compaq presario that originally vista os, the system crashed and I could get the recovery work so I installed windows xp and now I'm having problems with the sound. What should I do? I tried to locate the drivers requarding info. I keep getting error messages indicating that I have no audio device. Is it possible to go back to vista? I don't have an instillation cd or recovery for vista cd. Any help would be great.

    Hello

    Go to the link drivers HP > search your computer number model > XP OS > download and install the audio drivers.

    http://WWW8.HP.com/us/en/support-drivers.html

    If no audio driver XP is available, HP provides them.

    Through the installation of XP, you have destroyed the provided HP recovery Partition Vista to reinstall Vista:

    Solve a common problem of recovery with the HP Compaq computers.
    If the original operating system is changed to a non - Vista OS, the Recovery Manager cannot be started from either the desktop or by pressing f11 at startup. You can use the recovery disk to restore the computer to the original state of Vista. If you are using a non - Vista OS, you can use a third-party partition management program to recover hard disk space.
     
    Contact HP and ask them to send you a set of Vista recovery disks.
    Normally, they do this for a small fee.
     

    Some manufacturers have more available Vista recovery disks.

    If this happens, you may need to try this instead:

    You can also borrow and use a Microsoft Vista DVD, which contains the files for the different editions of Vista (Home Basic, Home Premium, Business and Ultimate) must be installed. The product key on your computer / Laptop box determines what Edition is installed.

    Other manufacturers recovery DVDs are should not be used for this purpose.

    And you need to know the version of 'bit' for Vista, as 32-bit and 64-bit editions come on different DVDs

    Here's how to do a clean install of Vista using a DVD of Vista from Microsoft:

    "How to do a clean install and configure with a full Version of Vista '

    http://www.Vistax64.com/tutorials/117366-clean-install-full-version-Vista.html

    And phone Activation may be necessary when you use the above installation method.

    Debbie

    How do you know that the loss of your internet connection has nothing to do with the Windows updates? You must find the reason for the loss of the connection.

    How do you connect? Is a wired or wireless with a modem or a router? If a router is the router shared with another computer and this computer can connect to the internet? You need to determine if the problem is a fault on your computer or a failure to connect to your internet access provider?

    What error messages are reported?

    Event Viewer reports

    1. normally, when an error occurs on your computer looking in Event Viewer should be your starting point to find a solution. More related system errors are recorded and get an exact copy of the relevant report is important. Unfortunately, is not easy to understand reports and most of the users computer need help with their interpretation. I have to say later interpretation.

    2 Event Viewer includes three main newspapers of Windows. Here's the Application, security, and system. For purposes of troubleshooting system is by far the most important.

    3. to access the system log, select Start, Control Panel, administrative tools, Event Viewer, in the list on the left of the window select Windows and the system logs. Place the cursor on the system, right click and select filter current log. Check the front of the error and click OK and see you only reports errors. Click the Date and time column header to sort. You may need to click a second time to see the last report above.

    4. a tip for posting copies of error reports! Run Event Viewer and double-click the error you want to copy. Select the Details tab and check the box in front of the XML view. Click the copy button to place a copy in the Clipboard and close Event Viewer. Now start your message and paste it into the body of the message. Make sure that it is the first dough right out of the event viewer.

    5. He cautioned against three types of reports, information, and reports errors. In most situations, it is the error reports that offer the best information but sometimes WARNING reports provide useful clues.

    6. all reports have stamps date and hour and when troubleshooting, it is important to focus on the latest reports. Reports of studies from the point when the computer is started, and then check if a similar report appeared in the previous session. If errors do not repeat investigation as to why they happen is wasted effort.

    7. in the individual reports the most important information is the event ID and Source such as these help when looking for help on the internet. The description is just as important and copy the exact text to use as search criteria greatly helps achieve better results when using Google. Not paraphrase descriptions when other people asking for help.

  • High CPU use/Slow Performance after you install the updates of Windows

    I run Vista Business 32-bit.

    After you install many Windows updates in the last few days, I've known very slow performance after the system worked for a while. Resource monitor shows 70-100% CPU usage, even when you run all the apps (that I know of). This makes everyhting grind to a halt, same trip that the mouse jerky movements. I ran several complete system with McAfee anti virus scans and not found problems (using the latest software). The detail showed the so-called ", PID4 NT kernel and system" using 18% avialable CPU capacity, but this process is not always shown to use much more capacity when the slow performance occurs. Nothing else don't use much capacity CPU, I see.

    More recently, the capacity of the CPU became crazy, jumping from zero to 100% usage in a back a suite oscillation. When I shut down and restart, performance improves, but erodes little by little over time.

    Is this a sign of a virus, or is it a problem with the recent Windows updates or some kind of conflict with my software such as McAfee? How do I tell me what to do? Anyone else have this problem with the recent Windows updates?

    Help!  Thank you!!
