Anyone know of a way, or has data on the current draw to a notebook during various operating modes. I tried searching here, and google without any luck.
I know my laptop is rated up to 5A at 15V, but I assume there is significant headroom in that measure. How much would it draw while at idle? playing mp3? full cup utilization? etc?
I know I could just tap into the power line and check, but hesitant to do it. Also don't know if the current draw is proportional to battery charge i.e. is the battery really providing the current, and the power supply is just constantly recharging the battery.
Any insight, as always, is much appreciated.
Well, if you could find out the draws for all the parts of the system (mobo, cpu, hdd, screen, etc) you could configure a rough estimate. Probably the easiest way would be to tap in using a multimeter.
When a laptop is plugged in (AC Power) it does not use the battery at all - you can actually take it out.
