Dec 14, 2016 Intell system driver: Intel(R) ICH10 LPC Interface Controller - 3A18.installed every driver thrown my way but nothing works. Unknown device in device manager in Windows 7 64. Fresh Windows 7 64 Professional install directly to a formatted hard drive. Using an ASUS P5QL-EM main board with an Intel E7400 Core2.

Hi, Has this been resolved by either of you yet? I have the exact same problem; unknown device on a PCI Bus Hardware Ids are ACPI CPL0002 *CPL0002 Physical Device Object name is Device 0000004f I restored to Vista and took screenshots of the device manager to match it up to windows 7's device manager to see what was missing and the only thing was Microsofts ISCSI Initiator but I can't install v. 2.08 or earlier versions of that from Microsofts site Windows on 7; The site states that it comes installed with Vista. So it must with 7 aswell? Either way I tried every version with different compatibility settings and it said that an update.inf file couldn't be found.

Let me know if you need any more details. Camtasia Studio 8 Crack Download Free here. Any help would be appreciated. I'm also having this problem. I cannot find any ACPI drivers to remove this unknown device problem in windows 7. The driver hardware id is cpl0002. Seems like a lot of people with y430 has this problem. Also the windows 7 beta driver list seems to only have drivers for thinkpads and not ideapads.

Is it possible that this only happens on the 64-bit os of Windows 7? I've done some searching on google and several people have this problem with XP64 and Vista 64. Do all of you have windows 7 64 bit installed/. Finally Divyanshu solved the problem.

I feel so happy, so great. Lenovo Y430 I want to tell to all y430 lenovo users. Windows 7 unknown device compal embedded system control 0.0.0.2 version or 2.0.0.2.

Thermal mode ok. This driver is sitting on lenovo china, we were not able to figure it out, because of the language problem. My chinese friend helped me figure it out..

Click on the orange tab on the left side. Install the software. wait till it completes 'Yes you want to restart the computer now ' If you need any other driver for y430, let me know. Have a great day.

If you like my message reply to post. Divyanshu Arora.
