Notebook K8P04LA#ABM
Microsoft Windows 8.1 (64-bit)

I have an HP Notebook that came with Windows 10 installed. The hard drive has died and I have replaced it with the one from my older Laptop (not working for a different reason) but it has Windows 8.1 installed on it. To my amazement I have actually got it to boot up and every thing seems to work after installing some different drivers however the following "other" devices have missing drivers:

PCI Data Acquisition and signal processing controller

PCI Encryption/Decription controller

SM Bus Controller

Unknown Device (2 of these)

 

Can anyone tell me where I can get these drivers. I have tried finding them manually without success. Also anytime I try to use the "update windows" or "update driver" functions the process activates but then sits there indefinately searching for something. The cancel buttons do not work and the only way to exit is via task manager.

 

I have not made any changes to the Bios

 

Thanks for your time

You're very welcome.

 

You need to also install the graphics driver.  You should be seeing an Intel HD graphics adapter listed there.

 

This package provides the driver that enables the Intel High-Definition (HD) Graphics in supported notebook models that are running a supported operating system. If high-definition multimedia interface (HDMI) video output is supported, this package also installs the HDMI Audio Driver.

If windows update is not working, I suggest you run the built in windows update troubleshooter.

 

Or run the troubleshooter below...

Hi:

 

You need these W8.1 drivers...

 

PCI Data Acquisition and signal processing controller & one Unknown Device:

 

This package contains the driver that enables the Intel Dynamic Platform and Thermal Framework firmware. Intel Dynamic Platform and Thermal Framework provide system temperature and power utilization information for the system thermal protection to function properly. This package is provided for supported notebook models running a supported operating system.

 

http://ftp.hp.com/pub/softpaq/sp71001-71500/sp71262.exe

 

PCI Encryption/Decription controller:

 

This package provides the Intel Trusted Execution Engine Interface (TXE) Driver for the supported notebook models running a supported operating system. The Intel Trusted Execution Engine Interface enables the Secure Boot and provides services required for platform security features such as Intel Platform Trust Technology (Intel PPT).

 

http://ftp.hp.com/pub/softpaq/sp71001-71500/sp71264.exe

 

SMBus Controller:  Note install this driver first and restart the PC.

 

This package contains the Intel Chipset Installation Utility and Driver for supported notebook models and operating systems. This utility enables the operating system to show the correct name for the installed Intel hardware in the Microsoft Windows Device Manager.

 

http://ftp.hp.com/pub/softpaq/sp71001-71500/sp71260.exe

 

The other unknown device probably needs this driver...

 

This package provides the HP 3D Driveguard Software (HP ProtectSmart Hard Drive Protection) for supported notebook models that are running a supported operating system. The HP 3D Driveguard Software protects the hard drive by parking the heads if the notebook is accidentally dropped, or is abruptly impacted by another object.

Unless you are super happy with Windows 8.1 why not wipe it out and instal Windows 10?  The reason those things listed do not work properly is because the drivers are missing.  And that would be why Windows update does not work.  I am actually surprised that you got that far with the process.  Anyhow, you can make an install for Windows 10, and since it had Windows 10 before it should not be a problem.  You can find the install media looking HERE - "Windows Media Creation Tool"

Of course a working PC is required to download the media.  In order to find the missing drivers, Is this the model you have

If yes HERE ARE THE DRIVERS

Thanks for the help. I downloaded/installed the drivers and I no longer have any hardware with missing drivers, but I still have the problem where the update links do not seem to work. Does the process take a long time? I have left it searching for at least 30 mins without success.

I also have discovered another problem - I cannot connect to my TV via the HDMI port (it worked with windows 10). The TV sees I have connected but the laptop does not. In the display set up screen there is no external monitor found. Could this be another driver problem? The Display hardware is now identified as a "Microsoft basic adapter" is this normal?

 

The reason I would like to stay with my older windows 8.1 is because  it is in English. I bought my new computer in Mexico, where I now live, and got caught by the fact that windows 10 now has a single language version so of course it was the Spanish version and it cannot be changed!!!! Trying to troubleshoot computer problems when all the screens are in Spanish is very difficult if you are not fairly fluent in the language.

Thanks Paul and "theoldman" for your help and solutions. My laptop is now operational again. Now all I have to do is see if there is a way to recover any of the data from the drive that died. Luckily I backed up all my data a couple of weeks ago so I have not lost too much.

Thanks again - Ian

Anytime, Ian.
