  Also, my Wi - Fi Realtek RTL8723BE 802.11 adapter b/g/n gives me a headache, it is connected to the router, but my Internet connection is lost on a daily basis, and I have to turn the adapter wi - fi for it to work again (router is ok, I use other devices to connect to the net without frequent problems like that).

  Usually, I see this in the event handler:

  -Event 1014 name resolution for the name dns.msftncsi.com timed out after none of the servers configured DNS responded.

  -Event 4001 WLAN auto configuration service has stopped successfully. (not really a problem, I read)

  -Event 10002 Module WLAN Extensibility stopped. Path of the module: C:\Windows\system32\Rtlihvs.dll (solved by editing the registry)

  I tried to disable in the BIOS of the LAN device, camera, microphone, etc. but still the BSOD and wi - fi connectivity issues.

  Help, please!

  The gold standard for the diagnosis of ASD BSOD is called Windows Debugger.  While it's not rocket science there is a steep learning curve when all first start using it if you simply want your diagnose your best best is to let a more experienced analyst to make your

• Plugin-container constantly opens and closes when I try to access FlashMD stuff.

  When I try to see all the media that requires the plugin-container to start, it starts and then closes immediately and starts again and so on until it's just give up. It does not affect anything else in another browser, then unable to use flash applications, such as youtube videos, other types of services video and flash games. The plugin-container for applications of the unit works fine and is not affected. I tried to reinstall Firefox and reset it, but it did not work.

  Reinstall the flash player resolved all the problems.

• Screen randomly fades and brightens

  I have had my Droid for about a week and note that the brightness of the screen will wax and wane at random intervals.  Is this a malfunction or battery problem?  If anyone else has experienced this?

  It's probably not either.  The Droid has a light sensor.  If it is brilliant on, the screen comes on.  If it's black, it becomes darker.  What is probably happening is that light conditions are varying slightly... enough to make the brightness of the droid vary.

• HP Probook 450 G1; E9Y30EA #ABB: [Windows 10]: driver compatibility problems, sound buttons do not work

  Hi all

  I recently did a clean install of Windows 10 x 64 on my HP Probook 450 G1 (E9Y30EA), and after installing the drivers I noticed when I cut the sound, my Mute button will not change its amber color (or orange, yellow, regardless), as it did in Windows 7 and 8.1.

  In addition, another thing that does not work is shortened mute Microphone keyboard (fn + F8). It turns off the microphone, nor its LED lights.

  I have the latest version of the Support of hotkey driver installed (7.0.13.1) HP, HP Quick Launch Buttons, HP wireless button, installed, .NET Frameworks 2.0 and 3.0, etc... everything is up-to-date, but it still not working as it should. Micro just cut does not work and pressing (sound) Mute button mute, but its light remains white, so I often do not know if I got the sound we or off with the look of a look I did.

  On the other hand, HP wireless button works normally, and it changes color to Amber when I press on it to activate airplane Mode.

  TL; DR: After the installation of the Win10 Hotkey Mute Microphone work and his Mute button works, but the LED does not work.

  Is what I can do to fix that, or is this just a problem with the driver incompatibility which would be fixed in some future updates? Or it is something else, like Windows 10 question or maybe audio driver?

  Thanks in advance,

  W 8.1 IDT AUDIO driver was a solution for me. All the buttons work now.  HP should release W10 audio driver for this problem, as the wrong audio driver provided by W10 is a reason for this problem I think.

• my notebook, ProBook 450 G2 go goes into sleep mode when well even parameters of energy set to never.

  My notebook, ProBook 450 G2 goes into sleep mode when well even parameters of energy set to never. The operating system is Windows 7 Professional.  I had a technician Microsoft verifiez_ the. I also had HP tech check the. They both said that it was a hardware problem. I sent it to HP to fix it and they replaced the motherboard and said that they have tested. When I came back, it entered into mode 'sleep' again. I left my laptop for about 15 minutes and when I came back it was in mode 'sleep'. This always occurs after the laptop remained for about 15 minutes.

  Does anyone have a solution?

  I sent my laptop repair HP. They replaced some cables and motherboard, but it does not solve the problem. They finally replaced the Windows 7 operating system. Basically they gave me a new system. I spent 3 days to update windows with all the updates and then re-loading of my programs. What a mess!

• HP ProBook 450 G1: Laptop stops unexpectedly on battery

  Hello

  In recent days, I confronted the question that my laptop without any warrning only on battery, usually after stops the use of 50% battery.

  And the battery is not more than 98%.

  Computer laptop specifications and details:

  Spectell.com/HP-ProBook-450-G1-e9y02ea-Laptop/

  Now battery faster as well. (Laptop is not guaranteed now)

  You need to perform a test of battery status you can do by pressing F2 when you rewind upward to enter diagnostic mode. If you are out of warranty and the laptop is older than 2 years, the first thing we think of battery problems are that the battery is old and needs to be replaced.
