• Satellite A500 - unknown device after installing Win7

  Hello

  I just installed Windows 7 64 bit in my laptop Toshiba Satellite A500-132 and in Device Manager its saying that there is no unknown device ACPI\ENE0200. Do you know what drivers should I install?

  And the second problem is that when I installed the pack value there is usually a red light that shines through the headphone jack, but when I installed the audio driver of light disappeared and doesn t shine more.

  Y at - it a fix for this?

  Hello

  I agree with the user above. This sounds like the CIR port and you need to download this driver.

  But I a bit confused about the light in the headphone jack of Mr. are you sure that there's a light or you can post a photo for example?

• Need audio XP drivers for Satellite L300 (PCI-Device)

  Hello

  I installed windows xp pro on my satellite l300 and now I am looking for the drivers get all devices running.

  Unfortunately, I can't find the drivers for "PCI Device" which is, I suppose, the audio device. Also, I can't find any information about the manufacturer of this device.

  So can someone please tell me where I can find these drivers?

  Hello

  The L300 is a new series on the market. I checked the page European driver of Toshiba and it seems that XP drivers are not being released at this time

  What to say to boyfriend. I think you have to wait until Toshiba release all the XP drivers for this series L300

  By the way; As far as I know a few series L300 is equipped with the chip Realtek audio.

  If the its doesn't work under Win XP you could install the audio driver from Realtek site.

• Satellite A200 - unknown device after installing XP

  Hello.

  Satellite A200 PSAE6E.
  Install Windows XP instead of Vista.

  Everything well instead of a thing. Device Manager indicates PCI Memory controller is peripheral unknown and showed the symbol of the brand in question.

  What could do? I think I installed all the drivers that were possible to download from Toshiba support.

  Any suggestions? Really appreciate it.

  Peace!

  You will never find a driver for XP PCI memory controller.
  This material is only supported by Vista and so you can ignore this yellow exclamation point.

  Furthermore, cela I found on the Toshiba site:

  Hello

  Would it be possible that the 3rd party software that you have installed to use the USB ports has tangled up the whole system?

  The driver for the unknown device that appear in Device Manager can be identified very easily.

  I recommend this HowTo:
  http://forums.computers.Toshiba-Europe.com/forums/Ann.jspa?annID=78

  You have the Vendor ID and the device ID and the use of these two IDS in pci database would help you to find the right driver.

  By the way: If your Wlan and cam n t work, install the drivers matrix, you've already tried this?

  Hi guys

  You must install the Intel chipset driver and the ACPI driver.
  Take a look at the Intel site.

  Good luck.

• Satellite L300 PSLBGE - unknown device in Device Manager

  Hello!

  I would be very grateful for any help/tips if anyone has an idea what to do...

  My friend has the laptop mentioned above (w/o OS preinstalled) and we can't get the graphics card work properly - situation is the following

  (1) mobile intel 4 series express chipset family, and an unknown device with an exclamation mark in Device Manager
  (2) both are on the same PCI BUS 0, device 2?
  (3) intel does not work because there is no free resources (I should remove the unknown device?) to work with
  (4) HW ID for the unknown device is pci ven_8086 & dev_2A43 and intel pci ven_8086 & dev_2A42 (so basically the same, right?)
  (5) Finally, and most importantly, if I go to the desktop-customize-advanced (first of all no resolution 1280 * 800) I see under adapter type:. Exactly, nothing... under properties, it appears: device not plug and play, Super VGA and under driver, I see just the status and the ability to stop, off, automatic, ask... the device at startup... If I turn it off, the screen just does not shine when the laptop is turned on...
  Any ideas? I'm insaneeeeee...

  Vista Home Premium, all other Toshiba SW installed (value pack, intel BIOS 1.9, etc. - maybe the BIOS did it?)

  Thanks in advance!

  PS maybe SP1 I now install help?

  Hello

  Wait a minute: I checked the Vendor ID and Device ID on www.pcidatabase.com and this is the graphics card Intel. So I think that's the reason why you can t change the resolution of the screen.

  I guess you forgot to install the display driver. See the Web from Toshiba site because here you can download the driver:
  http://EU.computers.Toshiba-Europe.com-online decision-making supported Downloads & => Download drivers

  After that you should t have no exclamation point.

  You can install SP1 for Vista, but that does not solve the problem with the missing display driver. But you should install it because it contains a lot of updates to security, they are important. In addition, I recommend to install SP2 for Vista.

  Good bye

  Hello

  ACPI-> Advanced Configuration and Power Interface
  ACPI defines hardware and software interfaces that allow focus on the OS configuration and power management to enumerate and configure motherboard devices.
  For example: ACPI is necessary for the standby and hibernation mode.

  Now your question; the new BIOS has been updated and configured to using VISTA.
  It seems that VISTA was not compatible with the previous version of BIOS because the ACPI interface. Now you can install Vista on the laptop, but it seems that you need a driver. Possibly new chipset driver version might help. But as you probably know, the drivers are not available at this time. Unfortunately

• No audio device installed Satellite L300-28R (PSLB8E-12T018GR)

  Hello

  My English isn't the best, unfortunately. Maybe someone can help me.

  The following problem:

  A Satellite L300 ran without problems until now with windows 7 (32 bit). I had then increased PC speakers of this came of trust with a USB flash drive that will serve as an audio interface for mailboxes. He has been infected by the first recognized by Win7, installed, and I could use Ihne. But then the sound card integrated (Realtek HD Audio) is disabled. Now, when I remove the USB audio interface I have no more sound. There is a lack of complete the "Realtek HD Audio" entry in the audio control.

  In the Device Manager is not an entry ' Audio, video and game controllers' also appear longer. The interesting thing about the HD audio driver, but he is always installed correctly. It is found but no entry for more video, audio, game controllers, and if I was in the toolbar the look of speakers just click on it a red cross when he get up "no audio output device installed."

  On this, I tried to uninstall the system USB audio drivers (no problem) has restarted. Not always the same sound problem.

  That's why I completely uninstalled all drivers audio and tried Windows 7 default drivers. The same problem. I uninstalled the audio drivers, this time I tried the drivers Toshiba, same problem.

  Fact is I can remove all the drivers, reinstall, which happens without problem and the error message, then it is same because "drivers have been installed, the machine can be used now" I click on what there is also my drine Realtek HD Audio. But then I opened the Soundsteurung he wrote me, "No audio device installed" it's almost as if the onboard sound has been disabled in the BIOS, but unfortunately there is no entry exists, since the BIOS is usually something to bend parameters.

  I have integrated sound card in my vemutung the BIOS from a USB audio interface is disabled, I would now like to 'hidden' bios unlock options and manually activate the sound again. Unfortunately, I do not know how do I unlock the BIOS.

  Is there anything else maybe ideas, suggestions or solutions? Have already the system is set up with new same problem, the drivers are installed, the device is detected and marked as ready, but not input in the audio control and no entry in the Manager of devices for "audio, video and game controllers".

  Once had a similar problem with my desktop where I could pass without any problem, but the onboard sound in the BIOS again, unfortunately, what with the Toshiba BIOS Lite is not the case.

  Hope someone can help me here, slowly I won't now, so that a new installation was not, I see the problem with the BIOS setting.

  Answers in German would be nice

  Hi mate

  To be honest I'm not quite sure what the problem might be m.
  Your ad is also a bit confusing.

  First of all, the BIOS is not similar to the BIOS that you can find on desktop PC and as far as I know there is no special option to enable or disable the sound card.

  So I think that in your case, it s BIOS not deliver.
  I think that its Windows operating system that makes some disorders who knows maybe the registry is confused up similar facts is that you should see some yellow exclamation points in device if Manager driver would be absent or you should see an unknown device in the devices list

  The latest Realtek audio driver could be downloaded directly from the Realtek page, but even if the Realtek audio driver is not installed Win7 standard driver should recognize the sound chip and sound must be detected during the operating system installation.

  I think you should try to install a driver from Realtek but if this won't help you, then you should try a new installation of the OS. Get it back you would help define the laptop back to factory settings and I think it's the fastest solution in your case

• Satellite L300 - 1 year PSLBGE - device Modem problem

  Hey

  I try me set up my dial-up access, so I can use internet at home...
  It is said that any modem devices are
  but in the previous copy of windows that I had... everything was fine.
  would u please help me solve this problem?

  Portable computer system unit Toshiba satellite L300 1 year

  OS: Windows XP
  Note: I went on the site of toshiba drivers and I downloaded 3 files of modems here to try to update the modem driver
  but nothing helps and the problem persists
  Thanks for reading
  Your
  ~ Nour

  I guess that you have activated the Device Manager and there is no yellow exclamation point isn't good?
  Figure modem in the list?
  It should be!

  How have you tried to configure the dial-up access?
  You should do this;
  Go to the category modems Options - Control Panel - hardware and sound - and.
  In the local info window, select an area code; for example, 0.
  Then click the Modems tab, click Add.
  If a User Account Control warning window appears, click on continue, and then click Next.
  Now Windows Vista should attempt to detect the modem.
  When the modem installation is complete, click Finish.

  Then the new modem installed should appear. Click OK to close the Options of Modem and telephony.
  Now, your modem is installed correctly, and you must now create a modem connection.
