Most laptops have similar batteries, it shouldn't be an issue.
I've never had a major issue with my own, a few questions now and again, most recently at T5 when the security man spotted it in my tray, placed there so it wasn't masked by the contents of my bag, and triumphantly held it up for his supervisor to make a call decrying "Aha what's this?". Supervisor was fine was fine, all I had to do was switch it on. 99% of the time no eyelids are batted as all sorts of radios go through daily , often with staff.
