Driver: audio, video,modem, SMK PnP TABLET - Panasonic Toughbook CF-73 Notebook

Hi
Usually there are 2 transistors for each channel, if you don't know the numbers on the transistors.
there is another way to get as close as possible to have equal or similar to the same type of transistors (NPN/PNP)
example: 2SA is PNP transistor.
there are (2SA/2SC) transistors and there are (2SB/2SD)
complementary transistors
1: you have to know the supply voltage for the transistors
2: choose transistors that it is equal to the current and voltage that suits the supply voltage.
follow this link to find suitable transistors.
be aware and be careful that there other parts you need to check on the power amplifier circuit, resistors,capacitors and drivers etc...
I would suggest (2SD1047/2SB817)

Good luck
Hope this helps

I cannot say for certain; however, several reasons cause this to happen. One is Old communication drivers need to be replaced with updated versions. Distance can be factor; how far from the source (Modem or WiFi sender) to the tablet? Then there is hardware factor> some internal Wi-Fi receivers inside of the tablets start to weaken over time and die completely sometime down the road. The final factor can be damage to the sensitive electronic parts and circuit board. If a tablet has been dropped or misused; the tiny and thin mainboard could fracture. Cold and/or heat could open a vital connection and if the board has a separation point, the opening (called a SHORT) will disconnect a portion of Audio, Video, or Communication sections. Your problem has a variety of possibilities which require actual inspection of the Tablet by a Technician.

Clarify me please your laptop's brand / model and your Op. System (windows XP, windows Vista, windows 7) to guide you to download and install the drivers.

Waiting clarification, don't hesitate to post.

Thanks and regards

Connect the system the internet, click your start menu, scroll to control panel and click it. From your control panel, double click system icon, when it opens, click hardware and thereafter, click device manager.

You would see a list of your hardware, scroll to audio, right click on it and press drivers update. The audio driver will automatically be installed from the internet. The same applies to the VGA.

Make sure the internet connection is strong enough to download the drivers, it might not download if internet speed is slow.

Best wishes.

I want drivers for multimedia audio controller and pci modem.Multimedia Audio Controller
2. Network Controller
3. PCI Modem
4. Video Controller
5. Video Controller (VGA Compatible)

www.hp.com would be a good starting point. Compaq is manufatured by HP. There should be a support/downloads page on the website

Go to Computer>Properties and go into Device Manager. Under Sound, Video and Game Controllers, you will see your device listed with a Question Mark next to it, see if you can right-click and check for Driver Software. If it is Conexant AC97 or Conexant HD, you can easily download the installer from various sites.

i have the same problem and i have the software and it says its not compatible

I DO NOT KNOW IF THIS WILL HELP BUT I WILL GIVE YOU ALL THE INFO I GOT OFF MY PC ABOUT THE MODEM

MANUFACTUER - CIRRUS LOGIC

CIRRUS LOGIC 33600 bps PnP V34

DRIVER VERSION 5.1.2535.0
IM SORRY BUT THAT IS ALL I CAN GIVE YOU

THANKS
