How to make hibernate process uninterruptible?

I'm having issues where putting the laptop into hibernate just randomly gets interrupted by SOMETHING... I can't tell what it is, but I did discover that touching any keyboard keys will interrupt it. It doesn't matter whether I hibernate by closing the lid or by clicking the Start menu. I'm on a Dell Latitude E6540 and I've already updated all the drivers etc and cleared all the caches ETC.

So, I just want the thing to hibernate unless I maybe hit some combination of keys (that would act as an abort function), but I'm not finding how to deal with any of this.

1. I want hibernate to be uninterruptible.
2. Except for when I hit some combination of keys on the keyboard.

Does anyone understand the hibernation process enough to deal with this issue?

Does it stop hibernating even if you don't touch the keys? Does it just seem to wake up on it's own?

If it were me hitting the keys, I'd know what it is.

I'm hoping someone with understanding of the issue can help.

Open a CMD prompt

Type
powercfg -lastwake
it should display the reason for the last wake event.

If you want I've included a batch file that sends the output to a file C:\Wakeup.Log so you can get a list to show if it's always the same event or more random

The contents is just powercfg -lastwake >> C:\Wakeup.Log

WakeInfo.bat

Downloading the WakeInfo.bat file says "Failed - Forbidden"

Unplanned wake events are often caused by the mouse, the slightest vibration can cause the mouse to move enough to register a movement - enough to trigger the wake.

You can usually adjust things in the hardware drivers but the simplest way is to turn the mouse over on it's back which should stop the accidental movement

I've used two different mice in the 5 years I've had this laptop (yes it still runs amazingly)... yet this issue only started happening months ago or something.
