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. In practice it doesn't matter at all. By the way, laptop "chargers" are technically not chargers at all.
Either plugged in or on battery power are good options for a laptop. Keeping it plugged in will be good for extended sessions of using the laptop while using it on the battery is good for when you are on the go. If you are on battery, keep your power adapter handy at all times to charge it when it goes low.
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.
In practice it doesn't matter at all. By the way, laptop "chargers" are technically not chargers at all. The circuitry responsible for charging the battery is on the laptop motherboard and battery itself, while the power supply just outputs a constant voltage for the laptop to use.
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. They use a switchmode PSU which are normally fairly resilient to crappy power.
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. I'd keep it plugged in. Some laptops have a threshold where the AC doesn't charge the battery at all until it drops below a certain point.

Question
I suspect this is a function of the power supply energizing, and the BIOS waking up. The BIOS then tells the power supply to turn off because "Restore on AC Power Loss" is disabled. Your power supply doesn''t have it''s own power switch so it relies on the BIOS to check the chassis switch and turn on when requested.

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-load voltage.
Power cord in the laptop''s first or in the AC wall outlet
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 milliseconds.
