I have a MacBookPro6,2 (MC372LL/A). The battery had died and can't run the latest macOS, so I installed Linux Mint on it with the idea to use it as a media computer. It was booting up as soon as the adapter was connected to the laptop. Now that I have installed a replacement battery, I'd like it to power up when the adapter provides power.

Prior to the battery replacement, plugging the adapter into the wall and laptop (in either order) would cause the laptop to boot. Now, it does not.

(Details for the curious: I have a power strip on a remote-control power switch for the TV, etc.; the laptop is set to not sleep with the lid closed; a cron job will shut the laptop off if the lid is closed, if it's connected to the TV, and if the adapter is unpowered.)

I've ready elsewhere about people having it start upon being plugged in and wanting it to not do this, so I'm imagining there must be a way to make it do this on purpose. Some places have suggested resetting the parameter RAM (which I understand is related to NVRAM/EFI variables) or resetting the SMC. I've read that if the batter cycle count is above a certain number, this will happen as well, so I'm willing to manually modify that if that's possible.

Any thoughts?
