I've had my NST Glowlight for roughly a year (so the warranty's run out). I haven't used it since October or so, and when I tried to charge and boot it recently, it doesn't do anything. When I plug it in, the green LED immediately turns on, and if I wiggle the charging cable a bit, it'll turn to amber, but no matter what I do, the thing won't turn on. However, the backlight will work (for as long as it's plugged in; the backlight will turn back off after about 30 seconds if I unplug it). I've taken off the back panel to have a look at the battery. It seems fine: the positive and negative terminals read ~4.10V, and like I said, the backlight works. I've also tried all of the standard reset things such as holding the power button for 20-30 seconds, holding both the power and the N button for 20-30 seconds, leaving the battery unplugged for a while then trying to charge it, trying to charge it for a long period of time (about 6-8 hours).

In any case, nothing I've tried has worked, and I'm starting to get frustrated. The other two times this has happened, I could just return it and get a new one, but now that that warranty's gone, I'd have to buy a new one, which I'm not really all that willing to do.

If anyone has any ideas or insight, I'd be very grateful. Thank you in advance.

A voltmeter on the battery with no load might be a red herring.

A 100 ohm to 1K should be enough of a load.

A Nook without a battery will refuse to boot, however it will pop up in bootloader mode for a bit.

If you just plug in a USB cable does it popup on your PC "New device found"?

You can probably skip to the end.
