You might need to set your system to hibernate instead of sleep. Modern x86 laptops lack proper standby power states — they only have a low power "darkwake" state in which they're able to do things like periodically check email, and instantly "wake up" from. Microsoft bills this as "modern standby". That's nice in concept, but it rarely if ever works as it's supposed to, especially under Linux. I had to set my Lenovo ThinkPad X1 Nano up so after being closed while unplugged for an hour or so it automatically hibernates, because otherwise it'll never properly sleep and Windows will drain its battery. It's stupid but the only machines that reliably sleep these days are MacBooks.
