Did you do it via windows update or microsoft's website. So far windows update says no new upates available for me.

I did the download from the MS website.  It was released today.  Automatic updates, I believe will be at a later release.

SP1 works fine on the 1530 but expect several hours to install

See my posts here

and here

I am glad to hear you had no problems.  I cannot get it from Automatic Updates most likely because I have the "fingerprint Reader" which is a known problem for SP1.  It's under "Casue 5" in the provided link.

Sigmatel is also lised as a problem and I believe I have that as well.  Not sure how to procede from here.  I did write UPEK (the company who makes Fingerprint Reader) and asked if they plan on releasing updated drivers.  Hopefully I'll hear back from them. 

Again, I am glad to hear you successfully installed SP1.  Do you have any of the software listed in the link I provided?

I also updated to SP1 by means of Automatic Update. The download is only 66MB instead of ~450MB in MS Download Center. It took ~30min to install and only 1 Reboot. It was yesterday first release in MS Download Center and a couple of hours later in Windows Update.

Regarding Fingerprint: I have the fingerprint sensor running as well and had no Problems updating. However I had a more recent version installed:

Dell's Fingerprint driver download version : 1.9.2.93

UPEK Homepage up to date driver version : 1.9.2.111

If you really think it's the Fingerprint, then you try the more up to date version:

I had no problems with SigmalTel. I have installed Dell's Version 6.10.0.5609. Unfortunately SigmaTel does not provide updates to end users:

"IDT currently does not provide end-user support or drivers for PC Audio products. This includes the PC and Notebook audio product lines acquired from Sigmatel."

BTW: I have an M1300 and am talking about Vista 32 Bit.

The Size of the download will depend on which version of Vista you have. Vista home premium download is smaller than Vista Ultimate.

In the beta install took about 2hours and required several restarts. The final release takes about 20mins and restarts just once.

The fingerprint reader has been unaffected by the update.

The sigmatel sound card seems to be working fine

The 1530 seems pretty robust - I had the SP1 beta and Nivida desktop drivers and it still ran bug free (although I found Hi-Res video playback in  windows media player was a bit stuttery but it didn't effect other players like divx player, quicktime or powerdvd).

After updating the UPEK driver and uninstalling the Sigmatel audio driver, SP1 became available to me via Windows Update. Once my machine was updated to SP1, I reinstalled the Sigmatel driver with no issues.

if you have Dell 1505 wireless N card, do not install SP1.

I am assuming it's driver issue. I have tried reinstall driver but still no luck.

Thanks for you info here it has been very helpful.  I went ahead and used your link to update my fingerprint reader (that update was not available to me under "Driver and Downloads" for my XPS 1530 - so without you putting the link here I would not have gotten it.)  I tried again to use Microsoft Automatic Update but it was still a no go - probably the Sigmatel issue.  I have Sigmatel 6.10.0.5609 which looks like it will not be a problem (based on the info you kindly shared here.)  I would still rather use Windows Update if I could but how do I "uninstall" the driver and then "reinstall" when SP1 is installed.

Also, I have a Dell Inspiron 1525 (both the XPS 1530 and the Inspiron 1525 were bought this month - so, they are both new) and the Dell Inspiron can get SP1 via Windows Update right now - it has Sigmatel 6.10.0.5614.  It does NOT have a fingerpoint reader.  Weird huh?  I have not installed SP1 on the Inspiron yet - I want to do the XPS first and see how it goes.

Thanks,

Sandy
