AIBU to be upset after he turned off my work laptop?

Don't. Touch. Other. People's. Personal. Stuff.

If he doesn't know that rule he really has been living in a bubble or under a rock.

He's a disrespectful twat. I'd say yes to his divorce offer and wish him a pleasant life.

Shutting down your own maybe, not someone else’s work laptop!

I know i should be shutting mine down overnight but i usually leave it on sleep and only shut down properly on the weekends.
I just need so many different documents and spreadsheets open it’s so much of a faff to close everything and re-open every morning

Not a fire risk.
Do you turn your fridge off ?

I would never EVER shut down someone else's laptop.
He is being utterly unreasonable - he never should have touched your work laptop without checking with you first.
The threatening divorce thing can be used to keep someone in line, shut them down. Reading your posts and some of the responses I wonder if he resents you furthering your career and is trying to sabotage it.

Yeah buts it’s her responsibility to save her work tbf

You don't shut down other peoples laptops without checking first. Especially one that obviously has a load of work open on it.
Unacceptable.

The system setting allow you to change what shutting the lid does. Mine does nothing, but the settings can be changed to say it goes into sleep, or hibernate or turns off.

No more of a risk than leaving your fridge, kettle, TV etc plugged in.

Or, he could just not turn it off. He has no need to, he was not asked to, it is none of his business. I have never told anyone in my household not to touch my laptop because they know never to touch my laptop. Just as I know not to touch theirs.

The tiniest thing being....progressing her career, passing a huge course to do so, her whole financial future?

It can be a fire risk leaving a laptop plugged in overnight so I kind of think you’re unreasonable. But how hard would it have been for him to just ask you to turn it off yourself?

Did he shut it down or just close it? If it’s just closed surely all the stuff would still be there?
Did you tell him how important it was and not to switch it off or presumed he knew? Seems like maybe you go crazy over the tiniest things for him to say about the divorce? Or he says this often over the tiniest things? Seems like a row which has opened up a can of worms

What a pair of drama llamas you both are

You obviously don’t touch someone else’s work laptop. At all. There’s no debate to be had here.

Hes also U to threaten divorce.

I think you might have gone mad because you’re under a ridiculous amount of pressure.

Who decided that you had to do this course from home “to save on childcare” whilst he can swan off to work.

I think you should look at paying for childcare if he won’t or can’t split 50:50. Trying to work with children knocking about the house unsupervised is not fair on anyone.

Laptops don't use a great deal of electricity, and if you need it left on he should leave it alone, was it just a mistake and he didn't know you needed it left on? If he wants a divorce over that things must be really bad, or was he joking?

Why is he touching her work laptop? He should not be touching her work laptop.

@VividOliveBee in contradiction to my other post, some people are just ‘thick-as-shit!’

My SIL switched off the plug charging her Hs phone at night as she was worried about the planet. Her H owns an APP and had a very important meeting in the morning to secure investment for his APP company. Zero charge in the phone to show his APP in the meeting. She kicked-off that he was being unreasonable and that he was ignorant to climate change. She stormed out the door and drove HER expensive NEW guzzling DIESEL SUV to work. 😂. Some people are ‘thick-as-shit!’ @VividOliveBee could your H be?

True, its not fair, but life's not always fair, and unless the course is completely run internally by the same company as does the updates, they can't be making allowances for every issue that may stop an exam candidate from being ready on time. Its not completely fair, but these are issues we all have to deal with every day in work environments.

No it doesn't. If she's due to be logged on at 9 for example and turns on her computer at 850 and the computer then wants to do a massive update before it will let her log on she will miss the start of the course.

And if the course is mandatory then it is not at all for a fetch to think that she will be failed for not turning up on time.

He should not have touched her work laptop without talking to her.

"the way to deal with this if it's so critical, is to check everything is working in good time beforehand.

no need for DH to interfere obvs. but leaving the laptop on overnight isn't a guarantee at all that all will be well in the morning"

So...if part of the risk to being ready is that her company may do an overnight s/w update that OP can't defer, and you agree she should be checking everything beforehand, but she shouldn't leave the laptop on overnight...she logically needs instead to get up at least an hour early, to put the laptop one, just in case there's and update? Not sure why that's a better approach!?

Its true that leaving it on doesn't guarantee there won't be some other issue, but NOT leaving it on significantly increases the likelihood of one!

Shutting your own laptop down is normal.

Shutting someone else's laptop down is interfering.

If he was worried about electricity, he should have asked.

It sounds as if he is being spiteful, doesn't care or is sabotaging you.

Updates for software should not be a factor in your success or otherwise on the course 🤔

My work managed laptop has to run frequent organisational updates otherwise it goes on slow mode and behaves strangely. Sometimes it is so slow that things like Zoom meetings time out. Saving on electricity just requires turning off the plug so the charger isn’t on. Then the battery can continue to power the laptop for updates etc, so sounds like this is more about control and being petty than saving electric. Who on earth shuts down (as in closes all applications) on someone else’s computer without checking first? Theres also sleep mode. If did that I’d be apologizing not asking for divorce. Definitely something else going on.

....and this is ...is a description of a loving partnership???

OP isn't "spiralling" she's rightfully angry.

Spiralling and irrational say so much more about inbuilt misogyny
