The correct answer is, "Use the charger according to your manufacturer's instructions." Generally, however, it doesn't make a difference which order you do it in.

If you plug in the power supply last, the inrush current will be much less extreme as you will not be shorting capacitors together. However, the output voltage of a badly designed power supply might overhoot when it gets first plugged in, subjecting the now connected laptop to a voltage transient above the allowed input voltage range.
Contrary to what most people think, the power circuitry is usually smart enough not to charge the battery after a threshold. The primary issue is temperature. Apple MacBooks actually run slower when you unplug the battery, as the A/C adaptor cannot provide all peeks that may occur in power usage.
Mostly, it''s because it''s easier on the connectors, with no spark between them as I plug the charger in. (it''s also probably easier on the output/filter stages of the charger). One exception is with one of the "HiPower" chargers I had, that will ONLY start charging if it is plugged into the pack first, and *then* into the wall.
So, when it comes to deciding whether to run your laptop on AC or battery, it''s important to weigh the pros and cons. Running on battery power may offer portability but
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.
If you plug the device into the power supply first, and then plug the power supply into the wall, then there may or may not be a temporary spike above the rated voltage depending on the load imposed by the electronic device. Since you are starting from 0 instead of the no-load voltage and ramping up, the device will certainly be subject to an
The answer is: YES and NO, it depends on the situation. Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery stops receiving charging energy and this
When turned on it will break the power supply between the battery and almost all 12-volt operated devices like lights, appliances, and so on. Just so you know, the many module boards operating your appliances also depend on battery power. When you are plugged into shore power, the disconnect switch should be turned on so that the appliances, etc., will
Purchasing a power supply with the correct power rating is essential to the safe operation of any mains powered or charged device. At The Power Supply Shop, we''re happy to say we''ve done the hard work for you, and promise that the replacement you purchase for your exact device is equivalent to the power rating of the original adapter.
So, when it comes to deciding whether to run your laptop on AC or battery, it''s important to weigh the pros and cons. Running on battery power may offer portability but comes with limitations like battery life and performance issues. On the other hand, using AC power provides a constant power source but restricts mobility. Consider your needs
However, this isn''t necessary in most cases as modern laptops automatically calibrate the battery. Should I charge my new laptop for 8 hours? It is not necessary to charge your new laptop battery for a specific amount of time. Charging times can vary depending on the battery''s capacity, the laptop model, and the power source. In general, it
Mostly, it''s because it''s easier on the connectors, with no spark between them as I plug the charger in. (it''s also probably easier on the output/filter stages of the charger).
Nowadays I tend to unplug the PC and thats about it, I touch the power supply because it makes me feel safer but idk if it is. The first way I heard was the plugged in method back when I was a child building my first PC with XP on it. But nowadays, though motherboards seem to be good at dealing with BS, I unplug the PC after I shut it down and
Should I Plug in the Phone First or the Charger First? Do you connect the plug to the power supply first, then use the data cable to connect to the mobile phone, or connect the data cable to the phone first and then connect the plug to the power supply?
Here is the info I have on the adapter and battery: Class 2 power supply Input 120VAC 60Hz 21.6W Output 9VDC 500mA. Adapter plug looks like a stereo headphone jack and I don''t know which part is
No, the battery will stop charging and the laptop will be powered by the outlet. Your battery should be fine👍
If you plug the power supply in first, it is going to be at (say) 9v, until you plug in the electronic device, and then its load will bring the supply down to somewhere around its
Confused whether or not it''s safe to leave the laptop plugged in at all times and if doing so damages the battery? Read on to get the answer.
Check the new battery''s voltage. A laptop battery''s voltage should be between 10.8 and 11.1. If the voltage is not in this range, the battery is broken and should be sent back. 2. Check how much power the new battery has. Most laptop batteries have between 4400 and 5200 mAh of power. If this number is lower, the battery won''t last as long
In theory it''s better to plug the AC cable first, and then insert the DC connector into the laptop.
First, if you plug into power and disconnect the house battery the lights, fans, and water pump should all work. If they don''t it means your RV converter isn''t turning the AC power to DC. If the lights are flickering and
If you plug the power supply in first, it is going to be at (say) 9v, until you plug in the electronic device, and then its load will bring the supply down to somewhere around its rated 5v. Note in this case, you will always be starting at a higher voltage than the rated voltage since the power supply has already plateaued at the no
The answer is: YES and NO, it depends on the situation. Having a battery fully charged and the laptop plugged in is not harmful, because as soon as the charge level reaches 100% the battery stops receiving charging energy and this energy is bypassed directly to the power supply system of
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
@Arjan I''m glad I didn''t buy any Apple laptops! Reading that article made me question Apple''s engineering practices. One of the mot important rules should be that power supply should be strong enough to provide power for computer under full load and to charge battery at the same time. I''m really disappointed in Apple right now. –

Here it may make a slight difference what order you plug them in. If you plug the power supply in first, it is going to be at (say) 9v, until you plug in the electronic device, and then its load will bring the supply down to somewhere around its rated 5v.
If you must follow a specific order, plug the charger into the AC power first, then plug the device to be charged into the charger. Why? Because I said so. That's about as good advice as you can get from anyone without specifying exact part numbers, and other specific information about the environment they are being used in.
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.
Better to get into the habit of not moving the laptop all over the house. In theory it's better to plug the AC cable first, and then insert the DC connector into the laptop.
Thus, keeping a battery in the laptop when it's not needed is very detrimental to it's life span. Also, it increases the risk of applying "top-up" charges, which again will shorten the life span. From a view point of your battery's health you should keep the laptop plugged into the wall and unplug the battery from the laptop.
