Is it possible to upgrade the linux kernel?


I've fully drained my battery at least over a dozen times between my three Pandori.. If you plug it in it will not power up at first, but takes about 5 minutes until the battery reaches a level that will allow for it to turn on and it will then power up and charge like normal. 
 
When connected to mains, mine always powers up straight away and starts charging. Though it's usually only a day or so of being totally flat.

Interesting, I could have sworn that I left it charging longer than that.

It can take like 30 minutes or so, that's how TI designed it, it does it's precharge thing while OMAP off so there is no chance to turn on a LED or anything to show some signs of life.
 
The exact length of time varies. It may be 5 minutes, it could be a couple hours. The problem is the battery voltage has dropped to very unsafe levels so the charge circuit just trickles power until it gets to a safe level, then it powers on so it can do a proper charge. If it's been sitting for a few weeks the battery is probably well below safe voltage so it'll take a long time.

This is normal operation, if your battery ran out and you can't charge it then that is broken charging and your experiences shouldn't be a reflection of expectation.

Perhaps, but all the other devices I've had over the years would give some indication that they were charging even after months of being on standby. Waiting a half hour or so and seeing no evidence that it's charging is problematic. I assume that the hardware aspect of that is more difficult than it might seem, but having devices plugged in and giving no sign of life is likely to confuse people.

That probably makes sense from an engineering stand point, but I've never had a device that would refuse to turn on because of low battery when connected to mains. Especially without giving signs of life. This is obviously not something I understand, but it seems like a poor engineering decision when the usually expectation is to give a sign that the battery is being charged.

Be happy that it will turn on at all after a while, I have dozens of devices that are simply dead if discharged too much, no matter how long they are hanging on a charging device - I have to do the "trickle charging" part manually by constantly connecting and disconnecting the charger. And yes, some of those will not show any charging information if the battery is too low to turn on.
