Code-28 driver acpi compliant system


right click on the driver with error and uninstall it. Restart your computer to install the generic drivers. Usually, computers generate their own generic drivers for the hardware parts in your computer. After doing that, update all drivers. You can find the updates in the website of the manufacturer. However, if you would like to get the correct drivers in no time then you can use RadarSync.

Microsoft ACPI-Compliant Embedded Controller Lenovo


The same model ThinkPadcan have different types of network, video and audio drivers and unless youknow exactly which one is installed in your ThinkPad, you need to download allthe drivers and install each driver until you find the right driver. When you download thedrivers, write down the device driver and it's file name so you have a recordof which driver you are installing and which directory the unzipped files arelocated on your hard drive. Go to the IBM/Lenovo WEBsite - support/download page and download the latest Windows device drivers foryour model computer, Use this link: - http://www-307.ibm.com/pc/support/site.wss/product.do?template=%2Fproductselection%2Flandingpages%2FbrowseByProductLandingPage.vm&sitestyle=lenovo&brandind=10&validate=true

Unknown device


I beleive that you had downgraded and installed a retail version of XP by erasing the preinstalled version of Vista in your Notebook.
However, all the drivers required for your Notebook may not be available with HP if your Notebook is preinstalled with Windows Vista.
I recommend you to try downloading and installing the drivers for HP Quick Launch Buttons from the link below for the first Unknown device in the Device Manager :
ftp://ftp.hp.com/pub/softpaq/sp38001-38500/sp38266.exe

Save the file on to the Desktop or My Documents folder and double click once the download is completed to install the drivers.
For the Ethernet Controller, I recommend you to download the LAN Card Drivers from the link below :
ftp://210.51.181.211/cn/nic/INSTALL_VISTA_6208_0922.zip

Coming to IEEE 1394 controller, you need to download and install the Chipset Drivers which are available through the link below :
http://us.download.nvidia.com/Windows/nForce/15.24/15.24_nforce_winxp32_international_whql.exe

Make sure that you download and save the files in the Notebook and double click them once the download is completed and restart the Notebook after installing each of the drivers provided above.
Hope this helps...

Wireless card not functioning/disabled after loading XP in a Compaq Presario C700T CTO Notebook PC


The wireless is not going to turn on and off via the switch properly until we get the drivers loaded to make it work. There are 3 possible types of wireless card it could be, so we have to find out the exact model number of your system. On the bottom there should be a label that has a P/N or part number listed. what are those numbers. Here's an example of the label:

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00033108&lc=en&cc=us&lang=en&os=2093&product=3632144&dlc=en

or

http://tinyurl.com/35dt4h

we need the info listed for #1, #2 and #3. Then we should be able to determine which adapter you have, and then we can (hopefully) find some Windows XP drivers for you.
