Good write up.
I have not been following the "won't charge" threads so I apologize if this was answered elsewhere. I'm curious to find out since the device must be powered on to charge, if the battery drains completely where the unit will not power on, does that meant that it can not be charged at that point?
Well, here's the problem, Nigel tried to point out a different situation with the HDD models (thanks Nigel, sorry I don't have one to know all about those "finer" details).
Anyway, if you have a flash memory only model...
As I tried to point out in my original post above... if the device is actually turned off (why I recommended holding down the power button for at least 10 seconds) just to make sure...
When you plug in the charger cable it will try to start up all by itself (if the battery is not so far totally dead than it can't). I guess I should try to clarify a minor point in my original post though because there is one thing that gets a bit tricky that can mess up a few people. If the device is trying to do anything at the power LED will either be on or will be flashing. As long as that LED is lighting up or flashing it will eventually charge (unless the device is totally defective). So, just let it do it's thing for at least 5 hours or so before trying to mess with it.
A key, and VERY IMPORTANT POINT, I tried to make in my original post is about that warning that the device displays that it can not charge if it is turned off. This is only important if the device has already turned itself back on after you plug in the charger. If you then try hold the power button so it displays the power stand-by and power off option... and then select to turn off (or press and hold it for 10 seconds trying to do a reset)... it will just turn off, and basically nuke the charging part of things... and end up with it (if you're lucky) going all the way down to just a trickle charge level (which could take over a whole day to ever charge).
Here's the one thing I forgot to mention (and maybe Nigel can fill in further details on the HDD models)...
If it doesn't seem to be charging, just unplug the charger for about half a minute or so and plug it in again.
Basically, it amounts to this, just plug in the the cable and charger that came from Archos and just go to bed and forget about. Do NOT start messing around pressing the power button or trying to figure out if it is or is not charging. Just leave it too do its thing and it WILL eventually charge. Doing ANYTHING else can force it into a far slower charging mode that you really don't want.
Now, if for some weird reason you think it will be more comfy on a water bottle (not recommended), or a pillow or sofa cushion that's up to you, but it REALLY will not do anything that will make it charge any faster. The real key to things is to just quit messing around with trying to figure out if it is charging or not. Just leave it "to do it's thing". The more you mess with it, the less change it has to do what it need to.
