I just find this amusing

my computer weighs 17.10 oz when at standard cpu load. It weighs 16.69 oz when powered off and left to drain for 1 hour. it then weighs 17.30 oz at peak power.

dead = 16.69oz = 473.15354g == 1.043124997892 lbs
standard load = 17.10oz = 484.7768 = 1.0687498998 lbs
high system load = 17.30oz = 490.4468g = 1.0812501101lbs

so basically, from powered off to high utilization, in theory, the power usage weighs 0.0381251122 lbs. To compare arbitrary number sequences that were cut off due to equipment faults: one penny = 0.006249994902 lbs (using the same scales and measurements). so the amount of change in weight (in theory current?) in my laptop weighs more than a penny.

lets compare this to what I've found online: https://www.howitworksdaily.com/does-electricity-ever-weigh-anything/ - basically says there is no weight fluctuation. https://www.sciencefocus.com/science/how-heavy-is-electricity/ - says there shouldn't be any change, unless electrons were added, but certainly not that relevant in size. https://www.reddit.com/r/NoStupidQuestions/comments/54ea9t/does_electricity_weigh_anything/ -  basically says that chemical changes in the battery may cause a change, but it should always weight more when charged and less when discharged, irrelevant to cpu usage, or powered on or off.

If anyone has any better reasoning for why this is the case, it would be nice to have linked. Thought about weighing capacitors when charged and not, but haven't gotten to that yet. I've also seen people say their phones weigh more when playing games or things that are high gpu usage.

Plz comment if can does the halping. K thnx. - Ferasdour
