Long flight - Spirit Airlines - No chargers - only HP Stream 11 Windows 10 laptop

Not all usb ports supply power when in suspend or shutdown. My Dell has 2 ports, one is labeled power delivery I think that's the term. anyway, one does and one does not deliver power when turned off.

It is configurable, Arlen.

You're dead wrong. It's not configurable. What made you think it was?

Short answer is *because* it is turned *OFF*.

If a laptop didn't completely shut down all of its electronics apart from the on/off button then the battery life would be terrible.

It has to be on for the USB ports to provide power out and then it may well negotiate a higher charge rate with your phone if it is USB C.

I carry a power block for long journeys since working USB charging ports on flights is far from guaranteed.

Wrong. My Acer Swift Edge has four USB ports of which one Type 3.2 provides power-off charging. It depends entirely on the laptop and the port, the version of Windows is irrelevant.

Not wrong, but 'it depends'.

Sure, a laptop which *does* have USB PD (Power Delivery), can provide power-off charging.

But for a laptop which does *not* have USB PD, MikeS is correct that the laptop has to be on to provide a little power to the USB ports, upto

But what you have done on each Windows version is relevant.

We don't have a precise model number. This is what a precise model number looks like.

If you had sufficient warning this would happen, you could carry a power bank.

"Can you take Anker 737 on a plane? Yes, it's allowed in your carry-on as it falls below the 100 Wh limit."

I suppose you could place a solar panel up against the window and pretend you're camping. There is a larger power bank that has a solar input, but that one would exceed the 100wh limit, if that's what the limit is. Maybe you could hide some batteries in your shampoo bottle :-)

My Lenovo's have USB power capability in standby or power off modes. However, that needs to be turned on in bios. Perhaps yours is similar... Did you look in bios?

Laptops with USB 3.2 with power off charging are not all that common.

The version of Windows/Linux/iOS is irrelevant but most laptops in circulation at present require that they are switched *on* and running before any of the external USB ports are powered up.

Otherwise you end up with your USB coffee warmer/fan discharging its battery when it is notionally switched off and sat at your desk.

Desktop PCs are often the other way around with some, possibly all USB ports powered for basic 500mA use even when the box is nominally off.

He should have booked with FOSS Airlines: Free, no ads and all the power and privacy he wants. ... Oops!

But indeed, it's configurable. As I wrote, with any laptop, you should at least get 500mA out of it, with a little luck 900mA. Not much for charging a smartphone, but probably enough to keep it running.

I would simply power off my phone if I suspect it can be discharged on arrival. I might actually need my phone there.

I understood his laptop could be double boot. The same laptop can be configured differently on each boot. Modern laptops can configure on bios what ports, if any, will supply charge when the laptop is off. And, at least on some laptops, you can reach the bios configuration from inside Windows.

Excellent :-)

And keeping within the Airbus style of doing things too.
