I have a 2019 MacBook Pro that I recently updated to MacOS 14, and I’ve since noticed that when I close the lid and then later pick it up, the MBP is always warm/hot. Even when I manually select “Sleep” from the Apple menu and then later touch or pick it up, it’s still warm/hot. This morning, after putting it to sleep last night, this morning when I went to use it, the battery was dead.
I’m attempting to reset the SMC on this MBP, but when I shut it down and try to press the left (shift + control + option) keys, it immediately powers on and starts to boot.
I wonder if /Applications/Utilities/Activity Monitor.app shows any processes using a large amount of CPU? Select View > All Processes, select the CPU tab, and click the % CPU column heading to sort by CPU usage. (I think… I’m on macOS 12.4, but hopefully this app hasn’t changed much?)
