Unknown device ACPI\LEN0068
Unknown device ACPI\LEN0068
Installed a new T420 with Windows 7 Enterprise and loaded drivers from Lenovo support site
One Unknown device remains in Device Manager
Hope someone knows what device driver this refers to

Re: Unknown device ACPI\LEN0068
It was the Power Management Driver (not Power Manager) and using Lenovo System Update for Windows 7/x64 solved it

Mine is fixed now too, thank you. I didn't see any other posts here and I just wanted to make sure you know your two were helpful to me. Thanks again, mt420.

Re: Unknown device ACPI\LEN0068
Can anyone share what 'Lenovo System Update' is? I am having a Devil of a time installing this driver.
Is it a utility program? I am trying to install it into T440P - Win7 64bit.
Thanks in advance

Re: Unknown device ACPI\LEN0068
Lenovo System Update is exactly as the name implies. It's a utility program that looks at your system, compare it to the latest Lenovo's database of software and update those utilities for you. Check to make sure that all the required support software for System Update is installed. Back in the day it used to work OK but maybe Lenovo no longer support the older models like they used to. Lenovo is a far cry from what IBM used to be. Mind you the place of laptops in everyday computing is not what it used to be either.

I couldn't agree more with your comparison between IBM & Lenovo.Cigarguy wrote: ↑Tue Jan 11, 2022 12:55 amLenovo System Update is exactly as the name implies.

Could you tell me where to find this software package? I didn't see anything (or missed it) on their DL page for the the T440P.
What is it called exactly? Perhaps I could locate it elsewhere?
I've never needed to use any Lenovo utility software on my T61's except the Power Manager for use with batteries.
If you want to see how much trouble this is giving me, please see my thread in the T440 area.
When I had the 32bit (x86) Win7 install, every single driver installed perfectly. After upgrading to 64bit abouit 1/3 of driver packages gave me trouble.
Especially the Intel video drivers, where I confirmed I was not alone, not by a long shot! So many ended up using Intel's drivers.
I tried FIVE Intel video packages until the last one finally worked. Sheeesh. And now, after all that, this is the only driver left.
One person even asked why I'm bothering installing it since it's such a problem.
I just don't feel right leaving it as 'Unknown...' I've never done that in decades of computer work.
Thank you very much for your response!!!!

Re: Unknown device ACPI\LEN0068
Could it be the 'Lenovo Migration Assistant' ? That's the only thing I could find that is close in the DL area.
While I'm not 'migrating' a system (I'm installing this one from scratch) I did read this:
'- Software update experience improved.'

Lenovo Active Protection System ?!
Or could it be the 'Lenovo Active Protection System' that would help me get that driver installed?
I had previously thought that Think Vantage software was only available for Win10 but I found the above for Win7.
I plan to update bios first and then go from there.
Thanks for your help with this nightmare.

Re: Unknown device ACPI\LEN0068
It's easy, just copy the driver id and search for it in google, which is ACPI\LEN0068, but so that you don't break your head, I'll search for it for you.

Out of the 40 odd solutions I have tried -on google- including those from Lenovo / HP / Treexy and various Drivers sites, only this works,johnmasster wrote: ↑Fri Feb 18, 2022 11:38 pmIt's easy, just copy the driver id and search for it in google, which is ACPI\LEN0068, but so that you don't break your head, I'll search for it for you.
