HP Probook 450 G3 (P5S63EA): crash HP 450 G3 Sound

First of all on my laptop.
I have the standart P5S63EA Setup (which is described on this page: http://www8.hp.com/ua/ru/products/laptops/product-detail.html?oid=9260217)

The problem is my healthy plant after several hours of work. Sometimes one to two day works all crashes, then sound but good.
To solve this problem, I have to restart my laptop or a party in sleep and restore. And then his restores.

On the pilots and others: I installed all drivers support page (most recent version of the drivers as offer cos support page). Also I have updated my BIOS to the latest version 1.07 at the moment.

Then when everything works fine, when I press a key at the top right to mute it is yellow lights up and sounds off. When I click on this button to new sound restores.

But after several hours of work, when sound was crashed, when I press this button to turn off his he countinue blush white. Windows shows me an icon that the sound was off tour. When I press the button - windows indicates that sound is disable, but it is false. When I try to play the audio file something is not working. Also when I open Control Panel - Audio and see all my audio input/output peripheral, in fact the microphone, when I try to say something - indicator does not show that I have something to say.
Also when I went in the properties of my speakers in and press the button to check its (Giraudoux) - no sound. Key to play the test is stucks in condition to play and when I try to press to stop read test - nothing.

COS, I had installed a latest driver conexant support page and I have also installed latest version of HP hotkey support and others.

Also small addition. By sound accidents, I mean that any new program that I started on my laptop cannot do ring, but last program launched to yet ring. For example, when I see the movie and in the background, I have a few messangers nitification and etc. - I hear one of my player, but other programs cannot make sounds. If I've close the player and opened it again - now I have no sound. And now when I press the button to turn off the sounds up right - it is now yellow lights and continue to shine white, but windows do on toggle the sound notification.
For the solution of this problem, I need to restart the computer.

I think that the problem in the driver.

Also when I opened the DST Audio Control Panel, go to the 2nd tab and disable all the "healthy development" after laptop computer reboot that they automatically turn on again.

Please help me with this problem!

To fix this, I have to restart my laptop or I need to enter a "sleep" mode and then get out of it. Sometimes, this help me (with sleep/unsleep).

A new driver driver Audio Conexant High-Definition (HD) (10.0.877.61 Rev.Q (March 2, 2016)) http://h20564.www2.hp.com/hpsc/swd/public/detail?swItemId=ob_162303_1 and more recent support page of my laptop has solved the problem with his accident!

I had a bug in the driver.

Thanks to all for the replies!

  • 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!

    so why insert it a finger print sensor to these business notebooks.is there any option to enable that works because this note book only for personal use

    In response to your questions:

    • Laptops of professional quality are equipped with sensors of finger prints for the same reason that consumers rank models offer the feature - biometrics are a method very popular to connect to your computer without having to type a password.

    SimplePass software runs on quality consumer laptops.

    • Security of client software runs on the professional quality laptops.

    Both programs offer some of the same functions.

    Options

    Install and run the Client Security

    OR

    If you run Windows 10

    and

    If you only want / need to connect to the computer with your fingerprint

    then

    You can set a PIN code and then activate the fingerprint reader to log that ships with the operating system Windows 10

    Start / Windows key > settings > accounts > Sign-In Options > PIN

    Help:

    Add or remove fingerprints - 10 Windows logon

    OR

    If you do not want to install / use the Client Security software on your computer

    and

    you do not want to be able to connect to (most) sites without having to type a password,

    then

    You can buy a password management program

    If you want, you can combine security software and password into a single service manager.

  • 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:

    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.

  • ProBook 450 G3 (T3L12UT #ABA): you can add video card for G3 450 Probook?

    Hello

    I am looking to buy a Probook 450 G3, a model that only comes with the integrated graphics card.  I see that in the manual a dedicated graphics card (if I read correctly) is an option for the laptop.  I wonder if anyone knows if this can be added later on (for example I am on a budget and cannot afford the model without a dedicated graphics card, but may be able to upgrade down the road)?

    Thank you

    Phil

    Hi, Phil:

    There is no provision to add a chart 'card' in your laptop as you can with many of the PC desktop.

    On most laptops, the GPU are part of the system board.

    Dedicated GPUS have a system of separate graphics memory of PC system memory and can also use part of this memory system if necessary.

    In order to have a graphics system dedicated to your laptop, the card mother together would be so should be replaced with one of those enrolled in the service including the switchable graphics feature manual.

    This would be very expensive and labor intensive.

    Only the most expensive mobile company HP workstations may still have different available graphics cards.
