Unknown device - need help.

Guys, I just fresh installed on my new harddrive and have a unknown device in other devices.

I thought I downloaded every single drivers from dell, but not sure which one this might be.

Little help please x).

 

Have you installed the Alienware Command Center yet? I seem to remember that took care of my last unknown device when I did my fresh install.

 

Now that you mention it. I have the same Unknown Device. I just installed my Momentus XT last night. I am investigating it now.


Update: Figured it out. Its the Free Fall Sensor.

 

Hmnn I thought I installed both already. WIll check back later.

Thanks.

 

I did install the free fall sensor, and there's still 1 unknown device.



Any other inputs?

 

Well check device manager and go to properties of the unknown device. On the Details Tab see what the Hardware ID is.

 

wait, there is a friggen free fall sensor? lol. I had no idea.

 

acpi/cpl0002

 

COMPAL Embedded System Control... Has to do with the battery. My driver looks like it was installed via Windows. Driver date 6/22/2009 version 1.0.0.1. See if you have EMSC.sys in your Windows/System32/Drivers folder. thats the file that mine is using

Update: Did a little digging. Check to see if you have a folder C:\Windows\System32\DriverStore\Filerepository\emsc.inf_AMD64_Neutral_..... That should be your driver if you dont have it I can host it on my dropbox for yah.

 

Doh. Going to try to reinstall the OS drive. Thanks!

 

That last device will be the On Screen Display pack from the dell site.

Don't ask me why, I don't know. But I have reinstalled the OS twice now and that is always the last thing to get rid of that single unknown device.

 

I just reinstalled OS. It wasn't a big deal since all already downloaded files were in separate partition. I did what I did the first time and there is no unkown device this time. Thanks everyone.

 

Glad to see that it all worked out for yah.

 

I have an M11x R1 and I to have an unknown device with the same hardware ID
acpi/cpl0002

Can anyone help pls?

 

It could just be a bad OS installation. I reinstalled, and everything seems well. Sorry I can't give you better resolution.

 

See if you have C:\Windows\System32\DriverStore\Filerepository\emsc.inf_AMD64_Neutral_.... folder. The driver should be in that folder. Use that to install.

 

dont have that folder, maybe because im on an r1?

 

or it wasnt installed during the OS install. You might just have to reinstall or search the Windows 7 CD for the driver.

 

Is the driver important? Or can I just leave it be?

 

I don't think it's a very important part. It seems to have a part with the battery from what I can tell. When I get home later I'll post a copy of the driver that I have to see If that resolves the issue.

 

That is the battery meter driver.

Driver for that is here:

Yeah, it's the free fall sensor to protect the hard drive. Basically, if it detects a free fall, it will park the head of the hard drive, to protect the hard drive from as much damage as possible from the impact.

 

Wish I had that before I reinstalled the OS lol. Thanks and rep + anyways.

 

kent1146,

Thanks for the link of the driver but windows still recognizes it as an unknown driver. I honestly dont know what's going on

 

so on your device manager, there is a battery icon right?

I know it might be a PITA, but you might want to reinstall everything over just incase. Like I said, the problem is gone after 2nd fresh install. Just make sure you download all drivers from dell, and go thru every single one of them one by one.

 

I did a force install using windows drivers I now have 2x

Microsoft ACPI-Compliant Control Method Battery

Should be alright right?

 

It is a ACPI device. You can try these drivers here and see if they work. Those are the ones I am using that came from Windows 7. They might be different since you are on a R1 but they are the same hardware IDs so it should work. Good Luck

 

I've tired everything posted here. I fresh installed windows several times, re installed drivers over and over and I still have an unknown device with the acpi/cpl0002 ID...

UPDATE!!

@idlehand - Worked like a charm! I screwed up the first attempt, but the second time worked perfect! Here is the device

COMPAL Embedded System Control

 

Glad I could help

 

Out of pure curiosity, why are you guys doing fresh OS installs? This laptop seems to come pretty much bloat-free and after having spent a few hours I was able to disable any non-Windows program loading up at startup or in task manager process tab...

 

Momentus XT would be my answer to that.

 

hard to really say...i just like having a totally fresh computer. i'm a little crazy.

 

link is 404

 

My Bad I was doing some file cleanups on my Dropbox and accidentally deleted it. I updated the link.

 

Thanks

It worked

 

Hi - I'm actually having the same issue with this unknown device with the same hardware ID. I did download your link, but unsure of what to do with it after extracting it. It is the file you mention with 4 files inside, but no setup or anything... I am probably missing some easy step, but is the next step after downloading the file?

 

My guess is to go to device manager, choose the unknown device, install driver by browsing to what you just extracted.

 

I had the same problem yesterday with my new Inspiron , it turned out that this is a Smart Battery . It took me a whole day to find the drivers, and i finally come with this tool DriverIdentifier.com Free Driver Update it find the drivers in just a few minutes.

Hope it help.

 

Thanks for the link man.

 

Another computer saved!

 

Exactly what I was needing, saved me a few hours re-imaging this beast. Made an account just to praise your name!

 

Anybody still have these files? I just reformatted my m11x, and have the same issue. Any help would be appreciated!
