Hey all.. I just heard something about this in another thread and I didnt even KNOW about this issue! Never was mentioned anywhere on Dell or anything I studied for the past week. Learned that using USB 2.0 has a power issue and if your on battery.. it will drain your power alot faster, this is caused by a MS driver bug it seems.
MS claims its working on a patch that was announced in Feb 2006, if its been done yet, I dont know.. not much data out there regarding this.
Article is here.

So only posting this because I know alot of new Dell dual core buyers including myself are coming here to learn more about the new dells and options etc.
So just making a post to let new people like myself know there is a issue and then to find out if it has been fixed or whats the REAL deal about this.

It was never publicized by Microsoft or Intel because Microsoft made it a confidential issue. This was actually found over a year ago (if memory serves) and Microsoft hasn't made a fix yet. I believe Intel has been working on a possible fix, and the proposed MS fix may or may not solve the ACPI issue.
Time will tell. Personally, I haven't noticed any problems.

Your title implies its a Core Duo issue when in fact it affects P-M's more than Core Duo's. AnandTech did a followup series of test after the TomsHardware article. Typical with Anand, his test was more through and enlighting.
A little hunting on your part will find the article . . . good read. :)

I read some of it stating a patch devised helped restore some battery life, but caused instability, however it was that duo core had issues with it vs a core solo.
Either way.. makes me wonder.. but most of the time Ill be on AC anyways.
Only thing I need is a logitech rumblepad and maybe a zboard.. I dont think that will cause a power drain or?

I haven't noticed any major issues regarding battery life. Interestingly enough, I have noticed that the optical drive and smart card reader are recognized as 'USB devices'.

Nice catch Warp! Rep points for you for posting the link. I didn't even see it in my update emails I receive from Micro$oft.

SYMPTOMS
When you unplug the AC power from a Microsoft Windows XP-based portable computer, the battery may drain more quickly than you expect. Therefore, the operating system may shut down prematurely.
The reference to dual core appears to have been dropped - it appears that the patch is for all processor types.

Question is.. is this the patch that made a few things unstable?
Then again.. this looks current! =D
Someone may want to sticky this.
