My HP laptop has a battery which cannot be removed. It is a massive heavy thing, and I understand that it's unwise to check it in, but I wish to anyway at my own risk. It's an international flight with no stopover (direct 3hr flight).
Am I still allowed to check in my laptop battery considering it cannot be removed? And I'm also confused, if a powerbank can't be checked in as it is a lithium ion battery, then why can laptop batteries inside a laptop be checked in?
