Curious. Can you pull the battery and operate off of the adapter only? That’s how we run our laptops, here at the house, and the batteries stay good for much longer, too.
Yes, you can pull the battery and operate just on the adapter, it pulls down about 14watts in that configuration - which is slightly higher than the 11watts it pulls when the battery’s fully charged and plugged in. Don’t know why the difference, but that’s with Windows or with Eeebuntu, so it’s gotta be at the hardware level.
