9 years ago The ARM core has no sleep/wakeup support. What remains is optimizing power usage, e.g.
- stopping services at night
- turning off hardware when not needed
- use frequency scaling (e.g. see here)
- replace power regulator (requires soldering, see previous link)
Right now the display is turned off, but perhaps it could sleep and wake up at a certain time. Good for power usage.
