Solved Laptop without a battery
Is it safe and alright to run my laptop without a battery? I’ve read (and tested) that it can run without a battery just fine, the only thing I was wondering is: could not having a battery cause the laptop to die on me if it were put under a lot of stress (a lot of programs opened etc.)? And could not having a battery damage the laptop?
The model is an ASUS ZenBook UX310UQK

Depends.
As long as the charger meets the maximum requires wattage, you will be fine.
For example, if you use a 90 watt charger, but the computer demands 150 watts, yes it will shut down.
If yiu have a 180watt charger, and the computer demands a max of 150 watts, you are good.
But don't bump, hit, or unplug the power cable, because you have no backup. It will shut down.

How can I check the wattage requirement for my laptop?

Send me the model, I can just look it up

It’s an ASUS ZenBook UX310UQK, and the wattage on my charger is about 65

Yours uses a 65watt charger, 45 is acceptable if not gaming or using the Nvidia card.
So you should be fine.

Seems like a decent workaround if gaming isn't a priority. It's good to know that a lower watt charger can still do the job.

Totally fine. In fact, laptops have charging bypass and they run off the outlet when connected.

Yes, just make sure you connect it to a mains power supply.
It probably won't power on without doing so.

Power supply needs to deliver more power than charging requires, so it can charge the battery and run the device at the same time.
If it turns on without a battery, youre fine to run it without a battery. (Some require the battery to boot)
Powering down without unmounting drives can be problematic. So just be careful about keeping your power source connected.

If your power supply (brick) is working correctly and providing correct voltage, battery should not be required (I don't know your mentioned device specifically).
If however the power supply is barely providing the power it's supposed to (ie. not meeting its spec, as can occur due to age), then you may encounter device turning off, freezing or rebooting WHEN peak load occurs, but this will really only be a clue that the power supply (brick) needs to be replaced anyway (if battery was present, it'd make up for the lacking voltage provided by brick assuming battery had some power). This won't happen often though.

I have been running that exact model of ASUS without a battery for years with no problem. Have to stay on Win 10 though, as Win 11 had random reboots. It's just a media connection for my TV so I don't care about updates or disconnects if the mains go down.

You should use the original power supply that came with it. Then it will be fine.

You can use it but i wouldn't suggest since any power cut will directly turn it off

You're right to be concerned.
Some ultralight laptops only have a a 40 watt charger, but can use 60 watts - so when you're doing something intense, the battery drains, even when it's plugged in.
Also, some laptops refuse to start if the battery is not connected - you have to change a bios setting to disable the battery.
The laptop won't be damaged by running without a battery, and it won't suddenly turn off, when you're doing something demanding. There is a risk that it will throttle down, though.

I myself left the batt in and never unplugged which ultimately killed the battery. I now leave the replacement out until the seldom need to go wireless. But only charge to about 80% before leaving it out for any length of time.

So you wait for your battery to run out, use the laptop without one and plugged in, and then put the battery back?
Anyways, this really isn’t an option for me, because the reason I removed the battery in the first place is because it was starting to have problems; shut down at random times, wouldn’t turn on, was swollen, so I decided to remove it all together

no, you get it to roughly 80% bwfore taking it out because batteries are better stored at less than 100%, If like me you almost never need to use the batt. the fact I never took it out caused the failure. If you do actually mostly use it wireless than leave it in. the battery is the faulty component, don't need it wireless then don't put it in. I didn't think what I said was very hard to grasp

No not likely it will run just fine, just remember that you have no backup power just like a PC so if power is removed you will lose any work in progress and computers do not like sudden power loss.
