At night usually my laptop Dell turns itself on all by itself?
I have to get up from bed to turn it off. I don't understand.
After I turn it off, 6-7 hours later it goes back on.
 

If you are using Windows. All the controls for turning the computer on and off are in the Display Settings.

I'm using Windows XP. Start>Settings>Control Panel> Display

Other Windows might be different. But that's where you control the on and off periods.
 
I believe there are other settings in the bios/cmos for ethernet/modem turn on and/or hybernation.
 

I have Windows 7 and no display screen. I have a control panel and I still don't see how to
fix this problem. Does it have to do with stopping the updates?

If you are not experienced with the BIOS don't go near it.

Go into the display, click on settings, and Power and set the power to the computer there.

You can make all the changes you want in the BIOS and chose to EXIT without saving those changes.

Also, if you totally screw up the Bios settings you can reboot the computer, go to the BIOS and reset to the default settings, F9, in the BIOS, on my computer.


Come on @Camper6, this isn't a big deal.

It is a big deal for an inexperienced person. You can totally screw up your settings. Most computer users never go there and don't even know how to get into the BIOS. You are using a cannon to shoot a mouse. It's not necessary if all you want to do is power off your laptop so it doesn't come on again till you want it to. You don't have to go into the BIOS to do that.
 
In the Power Options window, click the Choose what closing the lid does link on the left sidebar. Here you can choose what your power buttons do on your computer, as well as what happens when you shut the lid. You can select to Do nothing, Sleep, Hibernate, or Shut down!!
Easy peasy!!

"Wake-on-LAN (WoL) ..................... allows a computer to be turned on or awakened by a network message.The message is usually sent to the target computer by a program executed on a device connected to the same local area network such as a smartphone."

A WoL issue is a possibility in a computer turning on by itself if another network device as simple as a cell phone is set up incorrectly using god knows what settings on god knows which APP was installed on a phone or tablet or other device on the network.

I would be remiss not to mention this and to suggest checking these settings.
@Victor, do what you want and good luck.
