Is it safe to use MacBook Air without the battery?

"First, remove the swollen battery now. It is dangerous for your safety as it could cause a thermal invent which is highly toxic and could wreck your laptop. So be extremely careful and cool down the computer and remove the battery and isolate it in a box with some tapes. You don't want to get hurt because of a MacBook battery.

You can still use the computer without the battery, but the processor will run smoother, which means the effectiveness of the machines won't be here. The CPU clocks gets slowed when you remove it, but you should do this instead of risking a thermal event.

Good luck and take care."

it works without battery but a little bit slow I don’t know why, if it doesn’t work the first time try closing the lid and open again. Sometimes its working but screen light doesn’t come up and you can see your desktop and open documents really dark when you look close enough

Replacing a battery immediately is the best solution to avoid all types of threats both to the machine as well as the user. It also helps you directly, by having a new battery in place so that you dont have to compromise on the experience that you ideally have when the battery/laptop is new.

"SIMPLE! Yes, it is possible!

You press the < POWER > button, then you connect the power cable, you keep the power button pressed for another 5 seconds and then it starts. You need to do this whenever you disconnect the power cord.

Some say that if the laptop is only on power, the laptop power decreases by 20% ... now if you work a little more complicated, you buy a battery when you can. But until then you can use it like that."
