XPS 1340 Auto boots

I have a new XPS 1340, That seems to be having issues with starting up in the wee hours. Monday morning 4:30am I woke up for work, looked over at the Laptop sitting on the desk and the side hinge lights were on.opened screen and saw the login page. I always shut my computer down completely I don't use the hibernate feature.

Several Times last week I noticed when I came home from work and powered up the laptop instead of "starting Windows" it said "resuming Windows". I really don't know if this just started or has been this way since day one. I do know that the battery level always indicates 100% when I shut down and when I start up it's down to about 92% from just sitting turned off? Again I don't use hibernate I "Shut down". using windows 7.



Are their scheduled tasks that can start my machine I have noticed about 34 scheduled tasks in the scheduler can't quite undertsand why so many tasks come pre loaded. Anyway, most have never executed can I just delete them?any help, suggestions, greatly appreciated.

Spent the past 45 min trying to talk to Dell, been on hold guess lunch time is a bad idea.

Could I have a Progrram that is trying to "auto run once" ?

 

came home from work and windows 7 Started with the usual "Start Windows"
Seems like something is triggering the computer at early morning hours.
I was looking at the Task scheduler to see if I had an event possibly triggering the boot up but none are configured to that I can see. But alot are set up for early morning. Task Scheduler is giving me error messages when access it.

 

Check the BIOS too. Some computers have a feature to wake up or turn on at a specific time.

 

try typing "powercfg -lastwake" in the cmd prompt after this happens.. should tell you why it woke up if it was windows fault.

Hard shutdown like that is odd, only time thats happened to me was when i figured out my xbox remote control could wake up my laptop through the ir port on one of my old HP's..

My desktop would come on randomly it would seem when i put it to sleep, disabling "allow wake timers" in the advanced power profiles under sleep seemed to do the trick. but why yours wakes up from a complete shutdown is odd.

 

Check the BIOS too. Some computers have a feature to wake up or turn on at a specific time.
Today 06:20 PM

Thanks for the replys, I checked the bios and I don't have an option to wake at a specific time, One setting I see is WWAN enabled don't know what that is?

try typing "powercfg -lastwake" in the cmd prompt after this happens.. should tell you why it woke up if it was windows fault.

I typed into the DOS command prompt "powercfg -lastwake" and recieved, count "0". Interesting. does that mean windows did not initiate a power on, boot up?

Well it happened again. Woke up at 2:30am checked laptop OFF. got up again to go to work at 4:00am and laptop side hinge lights are glowing so to speak. open lid and their is my log on screen. I went through and made sure my power button is configured to shut down the computer last night prior to turning off. So,
A. BIOS has no field to enable or disable to start this computer from cold state.
B. I ran the command as suggested above to check when the last time windows woke the computer. "0".
C. I spoke breifly to a Dell Tech as I drove into work( only time I had) today, Which was dumb on my part I guess. I just wanted to see if I could actually talk to a rep, and maybe get a suggestion. They gave no help, other than to have my laptop with me next time I call.

I was thinking about doing a factory reimage to return everything back to the way I recieved the computer 17 days ago, just to see if it does it when nothing I have added or registerd is the culprit. But, this thing cranks up from a cold powered down state, Can windows Task Scheduler do stuff like this. I mean can a program in windows start this computer up at a specific time from a complete power off either A/C or Battery.

 

do you have the laptop connected to a wired network when you are at home?
something could trigger a wake on lan event if the networkcard are allowed too.

 

Ding ding ding! We have a winnar!

My XPS 16 had the same problem (I also do start -> shutdown), except since I have a BIOs password, it would get stuck on the BIOs password and the computer would run the battery to 0%.

Dell thought the battery was bad, so they replaced it. Did it that night, changed the settings and was working fine.

I was using a factory image with everything minus Mcafee the same

 

so that worked? wonder is tex has tried it.

Im trying to wrap my head whats going on.. As a lot of computers do this around me

 

Mr.High-Pinger, No. Wired Network. Thanks

Atlstang, Shadow25, Thanks for the info Got home from work stuck the phone to my ear and got lucky I guess. I just got off the phone with Dell since I didn't have access to the internet at the time we were talking, he walked me through bcdedit and we changed some values. I'm very sceptical about what he had me do. But I'll get up at 4:00am tomorrow when I go to work and check and see if it booted up.
If his approach worked then yee ha. If not, I'll be diabling all the wake timers for sure.

 

This morning the computer was stone cold. When I hit the power button the start up screen displayed "Starting Windows" as opposed to my login screen, and "Resuming Windows". So far this could be a solution. Still have not toggled the "wake timers" in the power settings. Fingers Crossed.
