As opposed to "a mistake" possibly?

I live off grid, there's no mains electricity anywhere near my home, so I'm very conscious of how these things work. What tends to happen is that once plugged in the adapters take up a surge of power, typically a bit beyond the stated maximum, and then cycle down to what it needs, a process that can take 2 to 5 seconds. So I have a PC adapter which is rated at 100w (I selected it with aircraft in mind too) but I've measured it surging to 143w on occasion, particularly if the battery is flat and the screen is on maximum. You can get a through-plug meter which demonstrates the wattage and you can perhaps find a power adapter which doesn't do this so much. The trouble is that BA's power will cut off against surges and then you'll struggle to get anywhere - your batteries will go down and every time you plug it it will surge even more than the previous surge. With my PC I know to go onboard fully charged, the surge is less if the battery is at 95%, and again before boarding, set the PC to Standby mode, bluetooth and Wifi antennae off, with the screen power down somewhat. Then first start off with the PC, just plug it in for a few minute to trickle up the battery a bit, then start up from Standby mode, leave it a bit to get the screen brighness up, and only gradually switch on the wifi antennae, if there is wifi onboard.
