The laptop uses ac adaptor when plugged in. Not battery. If you take a look at the battery icon when plugged in, you would see it goes to 100, then gets discharged to some level and charging back again. So the simple answer is that laptop does not use power from battery when plugged in. Battery gets charged and discharged. Does this kill ...
When you use a laptop computer close to a power outlet, plugging in the AC adapter to power the laptop is a good practice. Your laptop battery takes advantage of the power outlet and saves the battery for situations when there is no power outlet available.
Your laptop battery takes advantage of the power outlet and saves the battery for situations when there is no power outlet available. While using the AC adapter to power the laptop, you can leave the battery connected to the laptop. There is no need to remove the battery and keeping it in has benefits.
I found out that when battery is in and then the adapter is plugged, the adapter shuts off (output voltage gradually drops to 0), and the only way to restart it is to unplug it from AC power and plug it in again. Personally I wouldn't risk it. If, as you say, the power cord is short there's a good chance it'll come out during the operation anyway.
In general, having the charger plugged in and the battery too (if it is removeable), the battery will constantly be "charged" in the "constant voltage" mode to fight self-discharge. Many manufactures do not hard-cut the battery when the charger is connected, so the charging voltage is always applied.
While using the AC adapter to power the laptop, you can leave the battery connected to the laptop. There is no need to remove the battery and keeping it in has benefits. First, if the battery is not fully charged, leaving it connected to AC adapter allows the battery to be charged to full capacity over time.
@Arjan - Windows default power settings are generally to conserve more power at the expense of performance when running on battery. However, if AC power is connected then the battery is not needed, after all, the PSU can supply enough power to charge the battery AND run the laptop. @Bruce - no more so than any other PC.

However, if you are regularly switching off the AC and then back on again within short intervals throughout the day, this could actually increase costs due to more frequent use of energy. To avoid high bills in this case it''s best to leave it running at a consistent level until needed elsewhere in the house or turned off completely for longer periods of time.

So the simple answer is that laptop does not use power from battery when plugged in. Battery gets charged and discharged. Does this kill battery? Every battery has its cycle life. The most important thing is not to discharge it. Maybe it would be better to discharge it to 50% and then charge but I believe this is something you wouldn''t even ...
You can take the battery out and plug it back in while the system is on and plugged into AC power. No harm at all.
It must be safest to plug or unplug leads into the laptop when no power is present. This makes it potentially less harmful to the laptop if you somehow manage to misalign or short conductors …
Is it safe from electrical point of view to plug in the battery while the laptop is connected to AC and disconnect the AC power afterwards? What about the opposite side of …

If you''re on the go and plan to stay plugged in only for an hour or so before you''ll need the battery again, keep your battery attached. The process of shutting down the laptop, removing the battery, and then booting back up only to power down again shortly thereafter to reattach the battery (and turn on the laptop again when you get to your next stop) …
Thinking a bit here, I would say it is better to plug it first on the power source, and then plug to the laptop. Why is that: the chargers do not output the nominal voltage as soon as it is plugged. Some ramp up voltage gradually, some do …
It must be safest to plug or unplug leads into the laptop when no power is present. This makes it potentially less harmful to the laptop if you somehow manage to misalign or short conductors when pushing the connector in.
Modern laptops automatically cut off charging once the battery reaches its maximum capacity. If heating is not an issue, keep the battery inserted into the laptop. Charge the battery to at...
To convert battery power to AC power, you need an inverter, which converts DC power from the battery to AC power that can be used to power your device. The process of converting battery power to AC power involves several key concepts, including voltage, current, power, and electricity. Batteries produce direct current (DC) power, which flows in only one …

$begingroup$ This actually would be a good question for this site as it is basically about the impact of a design issue, except that it depends on knowledge of how the particular, unspecified charger / battery manager circuit is implemented, which isn''t really available information, beyond doing a survey of ICs which might commonly be used. On any of the other SO sites you are …
In theory it''s better to plug the AC cable first, and then insert the DC connector into the laptop. The idea is that the power supply could overshoot a tiny bit for a few milliseconds before the feedback circuit manages to adjust the output voltage to exactly how much is needed, so instead of let''s say 18.5v you may have 19-20v for a few ...
Inverters convert DC power to AC power by using electronic components such as capacitors, diodes, and transistors. They take the DC power from the car battery and convert it to a high-frequency AC signal. This signal is then filtered and amplified to produce a sine wave that is similar to the AC power you get from your home''s electrical ...
One key thing to consider (depending on where you live) is power cuts; if your computer suddenly lose AC power, it is not healthy. The same for your laptop, if you have removed the battery. The battery works like a UPS (uninterruptible power supply), so you can still use your laptop and turn it off safely.
The minute amounts of "topping up" the battery when you connect the power cable (it''s not AC in, the laptop adapter gives your laptop some DC voltage, like 12v / 16.5v / …
Is it safe from electrical point of view to plug in the battery while the laptop is connected to AC and disconnect the AC power afterwards? What about the opposite side of the question - is it safe (or what the damage could be) if you work on battery, plug in the AC and unplug the battery?
It''s like having a portable power plant. Cons of running the AC when idling: Here are some advantages of idling your car with the AC on it: 1. Consumption Of Fuel: The main drawback is this. Your automobile is still burning fuel when it is idling with the AC on. This implies that even while you are not moving, you are using fuel. Your gas ...
In theory it''s better to plug the AC cable first, and then insert the DC connector into the laptop. The idea is that the power supply could overshoot a tiny bit for a few milliseconds before the feedback circuit manages to adjust the output voltage to exactly how much is …
The minute amounts of "topping up" the battery when you connect the power cable (it''s not AC in, the laptop adapter gives your laptop some DC voltage, like 12v / 16.5v / 18v / 20v) after some running on battery are not a concern.
