• Unknown device ACPI\TOS1900 on Satellite A105-S2091

  Hello

  I just finished a * CLEAN * Vista install on my Satellite A105-S2091.
  Installation was smooth and clean.

  After installation of all recommendations * DRIVERS * (I chose not to install * ANY * Toshiba utility).
  I was left with two unknown devices in Device Manager.

  One was ACPI\TOS1901.
  After searching the forums, I found a thread that indicated that the installation of the supervisor of the Toshiba password utility, would be fixed

  I stayed with unknown device ACPI\TOS1900. A search here havenot been useful forums.
  I have + really + do not want to install the Toshiba utilities that are not absolutely necessary.

  Thank you!

• Need drivers 64-bit for Satellite P300-1BB

  Hello

  I have a Satellite P300-1BB with 4 GB of RAM, so I decided to upgrade my OS to Vista 64-bit. But I can't find 64-bit drivers. In the toshiba Web site, there are a lot of 32-bit drivers, but all 64-bit drivers. In my PC, in the folder c:/Toshiba, there is the 32-bit drivers and 64-bit drivers, but not all.

  So where I can find all the drivers 64-bit for my Satellite P300-1BB, and where I can find software of Toshiba (like toshiba assist, ect...) for Vista 64 bit?

  Thank you

  Hello

  Satellite P300 seems to be a new series for the moment so I think this might be the reason why you can't find the drivers 64-bit on Toshiba page

  But you worry about don t dude I m sure that Toshiba will be out the 64-bit driver next time I remember although 64-bit for the other series drivers were later also released.

  Just for the note;
  Some series have been equiupped with the same hardware devices. THEN maybe you could check some different unique series laptop drivers

  Hello

  I installed the 64 bit, win 7 on my dv8-1190ef, but there is an unknown device (ACPI/HPQ0004).

  That's the guard HP 3D drive.

  This is a slightly different model of dv8, but it will work. I guess HP forgot a list for your specific model number. I couldn't find FRO your support in any case page.

  And here's a more recent version

  I found this one for a HP Envy, but as mentioned, it will work fine for a dv8, or any other laptop with burner HP hardware 3D of the guard.

• Satellite C850 - 19(d) - unknown device ACPI/TOS6205 Windows 7

  I am a unknown device in windows 7 on a toshiba Satellite C850 - 19(d).
  The hardware ID is ACPI/TOS6205.

  Suggestions of Al in the forum and the net did not work:

  It is not bluetooth: the two drivers in the drivers download page, none has solved the problem:

  Can anyone help with this?
  Thanks in advance

  Hello

  The ACPI/TOS6205 seems to be the Bluetooth device.
  Satellite C850 - 19(d) was equipped with a Realtek RTL8188CE - VLSA WLan / Bt combo card.
  That's why I m sure its BT device.

  You said that you have installed the driver BT but it didn t work.
  I think that you did it wrong.

  The point is that WLan / Combo cards needs a filter driver BT package.
  IF you need to install: Realtek WLan driver, then driver Realtek BT filter package and, finally, the battery Toshiba BT.
