Computer turns on by itself

January 25, 2014 at 20:23:26
Specs: Windows 7, 2.7 ghz 6.00
Lately, my HP computer has been turning ON by itself, after being 'down' for a few hours ...but not turned off. It occurs during the day, night or whenever and often.

I tried the following but it still does it.....
* Control Panel
*Power Options
*Change Plan Settings
*Change advanced power settings
*Advance settings then
double clicked 'Sleep'
to 'Allow Wake Timers'
*Settings: It was on 'Enable' so I changed it to "Disable.
No matter if enabled or disabled, it still wakes up.
Appreciate any possible solutions. Thanks

Open Event Viewer. It would show you what has caused this.

Hi: I got to the Event Viewer (Local) and below were:
Custom Views
Window Logs
Applications & Service Logs
Subscriptions

I opened Window Logs, thinking that was the one to open but then I wasn't sure what to do next.

Check in Scheduled tasks. There might be something that is set to wake the computer up in order to run.

Hi Derek: Instead, I had gone to .....
*Control Panel
*Windows Update
*Clicked the down arrow and clicked on "For updates, let me choose whether to download or install them'
*Clicked 'Give me updates the same way I receive important updates'......
......Then show any needed updates
*Click Ok (If any important updates are shown and needed, then.....)
*Click install
*When done, reboot

*** I will see if this works this evening and during late night time hours. If it does work for a few days, I will get back. Thanks a bunch!

It's a possibility. Hope it works out, otherwise see what's lurking in Scheduled Tasks.
If it's a PC rather than a laptop also consider turning off hibernation if it happens again.

Hi Derek.......... The process I tried has not worked because a few minutes ago, my PC went on by itself. I had read the computer usually downloads updates automatically, therefore the 'wake up'. So that must not be so in this case.

I went into Task Scheduler, clicked on Create Basic Task but when it came to 'type in a name' and the process after that, I had no idea what to do. So I have no idea how to turn off 'hibernation' either as I am not into doing that.

I didn't mean you to create a new Scheduled Task, only to go through the ones that are there and see if any are set to wake the computer to run them. If so they can be set to not wake it up.

This might help with hibernate etc:

Hi Derek...........I just now went though the above steps using the suggested hyperlink ..... down to 'disable' and 'ok'. Disable was originally set so not sure this will change anything, unless there was a 'glitch'. I will have to wait a few hours, to see if it goes on by itself again.

If that doesn't do the trick then go to Scheduled Tasks and expand each of the task folders on the left (including sub-folders) - little arrows. I'm afraid it will be long and boring but the idea is to look at each one and see if "Wake the computer to run this task" is ticked in the Conditions tab on any of them. I doubt you will find more than one or two. Most likely they will be under the Windows sub heading.

If you find any, they cannot be altered on the main screen but instead you go to the right hand column under the "Selected Item" heading then choose Properties. They can be unticked from that screen, which is similar to the main screen. Make sure you OK the box.

Best make a note of which ones you have changed, just in case you want to change your mind. I doubt there is anything so important that you have to wake the computer to run it.

This should help as pictures can be far better than words:

OMG!! I just read the process that appears to really be involved! I will give it a try though. I have no idea why my PC started acting up recently. I had not done anything to create this problem......that I'm aware of. Maybe this has been occurring before and never noticed, except for the last week or so.

Earlier, I had another problem. I have a new Epson XP 400 computer and no matter what was tried, it just would not print, when connected to the computer but worked fine when not connected.

Through "Tom's" site, someone helped and now it prints.

I first want to wait in hopes the last process worked and if not, I will try this next process. Thanks

Hi Derek: Again, the HP computer went on by itself hours later, last night. Before going to bed, I shut it down, otherwise it tends to stay on for a long time, once it comes on by itself.

A few of your directions did not match, as there were no arrows next to anything in the Task Scheduler. Eventually, I got to see 'Wake the computer to run this task' and it already was unchecked. I then went to the 'Dummies' site and same thing.......nothing worked.

Thanks for your persistence but maybe there is no way to prevent this from happening. I had read others comments about the same thing happening with either desk tops or lap tops computers and no one seems to know how to solve it.

this behavior usually comes down to a bios setting and faulty power equipment.

go into the bios and disable the setting of restart after power failure
make sure your power cord is not loose at each end and/or replace the power cord.

I have seen where someone closes a door and that vibration is enough to giggle a loose power cord/surge suppressor that creates a temp loss of power. Giggled again the power reconnects and the unit powers up due to this bios setting.

The little arrows, maybe a poor description, are shown in figure 6 in the link I gave you (noticeable there on the left against Microsoft and Windows).

Hope I made it clear but it is not just "one task" you need to look at to find this 'Wake the computer to run this task', it is the whole darned lot of them. Figure 6 shows about 27 folders expanded out, and there can be others on your computer which need explanding out with the arrows(?) too. Did you check them all? Yours of-course will be different in quantity to those in the link example. It doesn't take too long to click through them and check.

As I said, there might only be one or two but they could be what is causing the restart. If you've checked them all out and none are ticked for "wake up" then we can move away from that idea.

Response #13 has given another possibility.

Hi Wanderer............ I am most confident all connections are secure but I have no idea what a 'bio' setting is. I know there hasn't been a power failure. My computer does not go off by itself. After it automatically goes down when not used, hours later it starts up by itself. Thanks

Well, now you've got me LOL - that link still opens for me on this very page. Have you tried restarting the computer (it often fixes temporary glitches)?

If it still refuses after that, do other pages open properly?

Also, are you using Internet Explorer? If you happen to have an alternative (such as Firefox or Google Chrome) let us know if the link still refuses to open on it/them.

Hi Derek' I rebooted and that link that would not come in, came in.. I clicked on 'Updated Devices" watched the video on updating drivers. Clicked on Automatic installation and as the person said To Right click Device Installation Setting, etc......it wasn't there.
---------------------------------------------------------------------------------
I then went to automatically install drivers Icon.........Start, Devices and Printers, Right click Devices installation Setting, again not there.

Yes, I am using Internet Explorer...and other pages open normally without problems. I realize this problem is not going anywhere and will accept the fact there is a glitch hiding some place among this computers inners.

" I have no idea what a 'bio' setting is"

Bios as in basic input and output. Its where you go to detect new hard drives or enable/disable built in devices like lpt/comm and lan ports.

"After it automatically goes down when not used, hours later it starts up by itself."

Same difference. At least look in the bios for that setting and set it to disabled. See if that makes the difference.

Or connect to a UPS and see if the behavior continues or not.

OK then if you can't find it checked any place then that's not the reason.

Don't know why you couldn't get to that link but its not important right now.

Best follow up on #19. If you don't know how to get into BIOS then let us have the make and model number of your computer.

Has this waking up only started happening recently and how long have you had the computer? The reason I'm asking is that the BIOS cannot suddenly change itself, so unless the computer has always done this it is not a BIOS issue.

Good Morning ............ I had thought it began happening about two weeks ago. This computer is in a back room of the house where there is a television, so I can notice if it goes on by itself in the evenings. I had not noticed it doing so until two weeks ago. If it had been doing that when I wasn't in there, then I have no idea.

The computer was purchased May, 2012

You have to be careful in BIOS otherwise you can cause issues. My feeling is that you would have noticed it if it had been doing this from day one, so it is unlikely to be a BIOS setting. The only setting that would cause this is the one that starts the computer after a power failure. I feel sure you would have noticed a significant power dip (lights etc).

When you were checking in Task Scheduler did you also check each entry in "Task Scheduler Library, also under the Hewlett Packard entry (expanded out)? HP have a lot of stuff that could cause wake-ups, such as maintenance, updates, etc. I have an HP and disabled many of their features, which seemed pointless. It would be worth looking in the HP control panel to see what is enabled.

Maybe there is some program that you have added fairly recently that is updating. Other than that I'm out of ideas.

Derek: There has not been a power change.

In the Task Scheduler Library, I had checked every entry & all expansions such as:.
HP entries
HP assistant
Microsoft entries
Internet Explorer etc.
Norton
Windows entries and there were many

With each of the above, none had 'Wake this computer to run this task' checked. I have never done so much, in regards to getting into areas I had not been familiar, so it has been an experience. But thankfully, there are many 'experts' out there, including yourself that are willing to go that extra mile to help. I have appreciated everyone's efforts and especially yours. I suppose I will just have to shut down the computer late at night, if it's going to continue as it has..... and I'm sure it will. Thank you

Yeah, pity, there must be a reason for this - seems it's hiding from us. Maybe if I was able to poke around inside your computer something would get uncovered but this situation might be one of those where trying to fix things with advice from afar just doesn't work out.

Hope something suddenly comes to you - it can happen.

HI Derek; FYI I have contacted HP via email and provided details, etc. about the problem. I had never seen that site but came across it. Usually those type sites want to be called and then charge by the minute but this computer is still under warranty, so that must be the reason. :)

Suppose to hear from them possibly tomorrow, Thursday or Friday with any suggestions, explanations, or a possible 'fix-it' solution. If they do come through with a possible fixer, I will follow their directions, if any and if the problem is gone......after waiting at least two days longer.....then I will pass their 'trick' along to you and others. But, if the problem still exists, then nobody will hear from me. :(

These are the directions...

*administrative tools
*task scheduler
*find under Windows...media center
*find mcupdate in History window
*click Triggers tab
*click properties in the actions window
*disable the automatic update

No, it didn't work, as the person directed in #32. There was no mention of clicking on 'Conditions'..........so I did.
----------------------------------------------------------------------------
I repeated the directions and when coming to 'windows', I double clicked 'windows', and below that, double clicked 'Media Center'.......on top I clicked on 'Conditions'........scrolled down to ''Wake the computer to run this task' ......it was 'checked', so I 'unchecked' it.

A few minutes ago, I repeated that process and yes, it still was unchecked.
I will have to periodically check to see if the computer goes on by itself and if it doesn't then that did the 'trick'. If not, then I still won't give up, even though I yet have to hear from HP support via email.
----------------------------------------------------------------------------------
I don't want to appear to be 'pesty' about this, but ironically that email from HP just came in suggesting I perform a hardware diagnosis test. A very long link was provided but not sure I want to do that, as maybe it might mess up something I might have achieved. Also claims 'error' may appear and if so, complicated directions.

Just thought... is this laptop sitting there with mains power totally "off" - mains adapter ideally removed from it; and thus only with battery power - when t turns itself on?

In the battery only state (no mains adapter connected - laptop and switched off) - does it still "switch itself on"?

Sorry, can't comment on link in 32 because, as I said earlier, it doesn't work. You can try pasting it in here again if you wish. If it was about Task Scheduler, yes, Conditions tab as per #9. Lets see how it goes.

Hardware fault, well all things are possible but I have a bit of a job to see why. If you can put the HP info on here somehow maybe it will make sense.

Hi Derek: I just returned home and the computer was on. I think any further attempts should be stopped, because this is taking up too much of your time and that's not right. I will just shut down the computer before retiring and if it goes on by itself during day time or evening hours, so be it.
I feel when it goes on and off by itself, it's not using much power or damaging anything....at least I hope not.

I will click on that link sent by HP and try my best to follow unfamiliar directions. Again, if I get nowhere, so be it but I do thank you for your time and considerations in attempting to fix this problem. You and others are always there to help and I appreciate it very much.
