I was in a public place on my laptop, and my laptop went into hibernation to save battery. I switched it back on and then the laptops BIOS came up saying that the battery was critically low, nothing bad here.

Instead of clicking continue, I decided to press "Diagnostics" instead. The diagnostics immediately began to run in the BIOS.

The screen began to show different coloured bars and patterns, obviously a screen test. Then a prompt appeared asking me if coloured bars were displayed. The options were yes and no, and a button saying "Exit" in the top right. Me, not wanting to do a full diagnostics on such a low battery, pressed exit.

The screen turned black, and then flashed red. The beeper on the motherboard began to beep at an ear-piercing volume. It sounded as if it was a bomb about to go off. Everyone around me stared and some people began to even panic. I tried switching it off by holding the power button but nothing was happening. People were just staring all around me.

After about 10 seconds, the beeping stopped and the screen displayed an error message similar to this:
"CRITICAL ERROR: Monitor test FAILED.
No user input was provided."

Moral of the story: Make your program account for all possible options.

So my grandma just called me saying that there is something wrong with the computer and the UPS is making a weird noise. When I went to find out what's going on, the UPS was beeping constantly and the computer was in the middle of a startup repair. Obviously there is no way to cancel the repair, and unplugging the UPS would probably do more harm to the computer. So we had to listen to that constant, loud, high-pitch noise while waiting for the startup repair to complete. And mind you, I'm talking about a very old and slow computer with windows 7 on it. After the repair was done, I quickly turned off the computer so I can reset the UPS and save my eardrums from burning in hell.

The worst thing is that I've downloaded the documentation of the UPS, and there was no mention of what a constant beeping means, it only described the meanings of normal beeping patterns (battery low, etc...).

My eyes are still ringing and my ears are still blurry from 20 minutes of that noise.

I must use windows at work and after 5 years of using mac I can say that windows is fucking loud, fucking beeps everywhere. Like you fucking do anything that has no results it’s beep - that’s fucking crazy I feel like I’m on some fucking road with assholes all over the place beeping on me.

I can work in silence on my mac, no software beeps by default.

Fucking Hell how can you listen to beep all day ?

Dear bluetooth headset,
I know your battery is low, thanks for the notice. I have 1 hour work left, after that you will get your charge. I also know you underestimate your own power and can do more than an hour on reserve.

So suck it up and stop being a whiny bitch blaring your damn "battery low"-beeps into my ears. It's way too loud and beeping every 10 seconds will only strain your power reserves and my nerves.

Yours sincerely,

I once was working on my family's business during summer and was doing something on the laptop that was there (according to the owner, it was in a "good shape" - oh my god that laptop nearly gave me cancer: an old Toshiba, running W10, with half the F keys not working - specially F5. I CAN'T LIVE WITHOUT F5 OH MY GOD -, and also the ➡ key (arrow keys). It was bought in a flea market and some IT guy, a friend of the owner, repaired it a bit and installed the OS because a laptop that old ran WinXP or Win Vista for sure) when suddenly it died on me.
I rebooted the thing and right before the time it should be showing the windows logo, the screen froze (on a black screen with some text) and it started to beep. Loudly. A loud continuous beep. I turned it off and on some times after that, seeing if turning it off and on did something (as it seems to work LoL) and it continued with the beeping. After a quick search I found out that that was a common problem with Toshibas that old, and that I needed to press F2 (that key worked thank god) when the black screen with the text showed up (I don't remember what was written there, it were some booting instructions, I think).
It worked. Great. Now the N key doesn't work when I press it. Greeeeeeeaaaaaat. Also it seemed that, when I opened the start menu, it would automatically write "nnnnnnnn(...)" without me pressing any key (pressing any key would make it stop though, maybe it was stuck).
Then I told the owner not to turn it off, because the laptop would start beeping and such (and I know he'd panic about it).
From then on I think it went off for good and now he's been using his own Toshiba, that runs Vista and is slow as all hell.
Moral of the story: he should have been used his crappy PC from the beginning, at least all its keys work

(Note: watching him type hurts my soul. When one is used to use both hands to type, and is fast-ish on the keyboard and uses tabs to change fields, watching someone type with only one hand every 2" or so and using the mouse to change fields hurts. So much time wasted 😭)
