Auto start up

Vikandgra · 27 Sep 2015

This is my 1st post so please be gentle

. My computer knowledge is basic.
I have networked / home grouped my laptop and home desktop. The laptop runs Windows 8.1 and the desktop now runs Windows10 upgraded from Windows 7.
Since the upgrade, every time I start up my laptop, the desktop also starts from the "off" position. This only happens from laptop to desktop and not in reverse. It is a wireless connection.
If someone can help me please explain it in very basic terms and not assume I understand :).
Thanks Graham

Hi Graham and welcome to Tenforums.

Let me get this straight:
Your laptop is off.
You've shutdown your desktop.
You turn on your laptop, and it wakes up your desktop?

Please try turning off Fast Startup on the desktop (W10 system) and do a few shutdowns/startups (NOT restarts) to see if this helps.

W10 has a wifi sharing feature which is enabled by default. Try disabling that.

Do you have WOL (Wake On Lan) enabled in your desktop BIOS? You're not sending any Magic Packets from your laptop, are you?

Thanks for the reply ....
I have turned off the fast startup as suggested but no luck there.
Where do I find the Wi-Fi sharing feature? and as far as having the WOL feature enabled where and how do I find it to check?

Hi Graham,
So, this is a very strange bird indeed! :)

First I will suggest some reading, to help you understand a few things (please create a restore point before you go changing settings in your system, just in case!):

This post is one of mine where I delve into the security/privacy settings on W10. There's a lot here, so don't feel overwhelmed. What I'd like you to be familiar with are the following links pertaining specifically to wifi sense and internet sharing in W10:

Since you have the computers networked, I want to address this side of it first. Since you now have Fast Startup turned off, we can be sure that power is removed from (just about) everything when you shutdown, because you will be truly shutdown and not in some hibernation state.

Once you've read through these and made any changes you require, check and see if the problem resolves. If not, let's move on.

Go to the properties of your wireless adapter and uncheck the box which says "Allow this device to wake the computer".
Settings>Devices>Device Manager>Network Adapters
Right-click your wireless adapter and select Properties.
In the Power Management Tab, uncheck the box as shown below:

Auto start up-wrls-adapter-properties-sleep-wake.png

This will determine whether or not some sort of Magic Packet is being sent from your laptop to wake up the desktop.

If the problem is resolved at this point, we then know that this is the culprit. This would work in conjuction with the WOL feature I mentioned. (Although, if you don't know what this is, I doubt you are specifically using this feature. Then again, there may be something installed on the laptop which is doing this.)

Another thing I'd like you to try is this: Disable your wireless network adapter on the desktop, and then shutdown.
Device Manager>right click wireless adapter>select Disable

With the desktop shutdown, turn on the laptop and see if the problem is resolved.

I can't give you specifics of your particular desktop, but in general, after having read the previous link I gave you from wikipedia on the WOL function, you should be able to google how to enter your specific BIOS, to check the settings. Here is another article which explains the concept. (Disregard the info on iOS and Linux.)

Let us know how it goes.

Thanks Simric for your patience ... sounds pretty involved so will have a go at it tomorrow (its nearly midnight here).
I had a look at the bit about Magic Packets and it lost me after about 3 lines!!! When you first mentioned them I thought it was slang for a virus or something like that .
Will let you know how I get on in the next day or so.
Cheers

No problem Graham, take your time. The main thing you need to know about Magic Packets is that they can be sent by programs to other computers to wake them up. That's why I want to rule out the possibility that your laptop is doing that. We may need a list of installed programs on the laptop, if we decide that's what's happening. That's all. Good night!
