I'm doing a round trip between the US and the UK with Delta, and intend to take my laptop. Unfortunately, the battery recently began to stop holding charge: when I plug in the charger and turn on my laptop, it works fine, but as soon as I remove or turn off the charger my laptop shuts down.

Will I still be able to take my laptop onto the plane in hand luggage and/or hold luggage?

The reason I ask is because I've been on domestic flights where they've required smartphones/tablets/laptops to be at least 20% charged when boarding. Here is a somewhat old link regarding minimum charge of electronics on flights to the US.

    Now that you've received an answer, I am just asking out of curiosity: why did you think that your airline cares about your laptop's battery being damaged or not? – gdrt Jul 17 '17 at 22:30

    +1. Interesting. Please add this comment to your question to get more upvotes. Because I think your reasoning and that link are essential for your question. – gdrt Jul 17 '17 at 22:48

I flew with Delta to the US last week. In the queue to the checkin counter (when they put those little stickers on the back of your passport) I was asked if all electronics where sufficiently charged to be able to demonstrate that they were working devices. However, at no point was I asked to actually do that.

My conclusion: you could be asked to power up the laptop but won't always. As far as I understood, what they mainly are concerned about is that you would replace the battery with explosives. For this reason I assume that powering up using the power cord will not be sufficient.

I was flying from Western Europe, but not the UK. I am not sure if this only applies to hand luggage or also to checked luggage.


If the battery doesn't work so you know you'll have to use the power cord anyway, could you remove the battery and leave it at home for your trip? I understood the issue to be that batteries were being used to conceal explosives, so if you don't have a battery at all that might be OK.

  • Whilst your understanding about the batteries concealing explosives may well be correct, you're assuming that if you showed a security person that there were no batteries, they would let you through. I suspect that way more likely is: "It can't be turned on, you can't take it through" "But there aren't any batteries" "My list says you can't take it, if it doesn't turn on" "But there isn't a risk" "My list says..." "But!..." "Sir, leave or I'll have you arrested". – Brondahl Apr 9 '18 at 14:23
