iPod Nano dead after flight

ajmull

My old iPod Nano is lifeless following a flight to Canaries and back, not a gig out of it. It was working fine before I went. I didn't use it as I also had a newer one (a present). Tried drying it out in the hot press and leaving it on charge - nothing. Any suggestions?

Did you get it wet? Why dry it out in the hotpress? Did you use it at altitude out of interest?

I ask because the maximum operating altitude for an ipod is: 10,000 feet (3000 m).

Title makes it sound like you're blaming the altitude but then you dry it in the hot press?
What happened? We need to know what went wrong before we can suggest how to fix it.

Have you held the Home and Power button down together for 10 seconds? This should kick into gear again.

Air pressure inside a plane is the equivalant of about 5,000 feet so shouldn't cause any damage to an electronic device regardless of the actual altitude.

Its working again now. Not quite sure why, but I had a bottle of water in the bag in the cabin of the plane with me and I wondered if that had something to do with it. It didn't obviously leak, but! Maybe it has dried out? Anyway thanks for the help. Alls well that ends well.

The next time your flying at high altitudes keep the iPod in your pocket. It protects it

Utter rubbish statement imo

Seems like its your opinion that's utter rubbish. I keep mine in pocket all the time while flying and have had no issues

Just because you have had no issues with it in your pocket does not mean it is the pocket that is preventing it from having issues.

I accept that but it's quite possible. It's worth a try for the op. it works for me

Protects it from what exactly?

The cabin altitude in any pressurised modern air transport aircraft will never exceed 8000ft unless in an emergency situation (oxygen masks drop around 13,000ft). Most electronic devices guarantee operation to 10,000ft. The cargo bays on aircraft are also pressurised (but not necessarily heated) so even if you put it in your checked in luggage the conditions will still not go outside of the designed operating parameters.

Also, iPads are approved for aviation use so have had to satisfy huge reliability requirements in order to achieve this approval so it says a lot about the construction of all Apple products.

It only 'works' for you because it hasn't been affected by some as yet unidentified threat, what on earth are you talking about?

Keeping it your pocket simply means that it will be at or near body temperature, it will not affect the air pressure and effectively will do absolutely nothing to 'protect' it.

Do you keep it under the pillow at night - what exactly are you protecting it from?

Well done you but the factual point is that having it in your pocket is NOT the reason why you don't have any problems with it:rolleyes:.

If you can explain the science as to why keeping it in your pocket protects it I'd love to know.

I never knew this.... I have quite happily used my ipod at 12605 ft / 3842m (not in a plane) and have never had an issue.

Keedowah

Of course I wasn't suggesting that using it on a plane was the cause of an issue!

We were travelling in Bolivia a few years ago and met a few people that had issues - La Paz is at about 12,000 ft

I too have used an iPhone and iPad outside of the pressure altitude listed in the specs (in an unpressurised aircraft). They're only really a guideline anyway, it's not going to break at 10,001 ft. Apple simply guarantee fully normal operations up to 10,000ft. After that if it doesn't work they you have no grounds for complaint.

OP, I keep mine wrapped in a silk sheet and only play classical music if I'm on a plane. No issues with it at all. Also, I've found (unrelated note) that hopping on one leg while petting your pet dog, seems to protect the dog. No issues with my dog yet!

Alright lads, point made. Lets try to get back to the topic.

Apple seem to have that 10,000 feet 'Maximum Operating Altitude' limit for all models of iPod and iPhone.

The only circumstances I'm aware of where altitude makes a difference is to hard disk drives, I can't see how a device with all solid-state electronics can be affected by thin air, unless there is an issue with overheating where the air is too thin to carry away the heat. However given that you can use these devices while they're in your pocket and they don't overheat, I'm really at a loss as why there is any limit for, for example, the iPod nano or iPod Touch or any model of iPhone.

When you use a device with a hard disk drive at a high altitude, the air pressure can be so low that the air 'cushion' between the read/write heads and the disk surface loses it's effectiveness which could lead to the heads touching and scraping the disk platter surface, this is known as a 'head crash' and is fatal. In the normal course of events the hydrophobic membrane fitted to all disk drives allows air (but not water vapour or dust) to flow in and out of the enclosure so as to equalise the air pressure and prevent stress on the enclosure. This means that the air inside a HDD is typically maintained at the same pressure as the outside.

For a disk to be certified to operate at extremely high altitudes, the enclosure needs to be pressurised and sealed (even for air flow) and it needs to be ruggedised to withstand extreme changes in outside air pressure, normal HDD enclosures are not manufactured to this tolerance.

Keeping your phone/ipod/etc in your pocket when flying is also going to potentially lead to dust ingress behind the screen. :eek: Especially if you keep dusty tissues in the same pocket.

Reason being that when landing the ever so slight air gaps between the glass and lcd will have a lower pressure than the surrounding air and this whatever is in the vicinity could get sucked in as the air pressures normalise.
