Take battery out and connect to power. If you see a red light where it lights up to show its charging then the hardware is OK.
Try with battery and see if it charges. NO LED means battery dead.
Need to know if the hardware is COMPLETELY dead or if the battery is the culprit.

If everything is ok and you just need to replace the battery then read this for a safety net while flashing - http://forum.xda-developers.com/showthread.php?t=296722

Sounds like battery contacts may be broken or cracked. Might be unfixable. :( Usually happens after a drop... You could try to re solder the contacts but no guarantees.

Are you charging with the original charger or USB/3rd party charger?
Did you let the battery go under 10% charge?

If you are charging without the original charger or with the usb cable it may not be getting the correct voltage which may be confusing the internal charging sensor.
This may also happen if you let your battery go below the 10% mark frequently.

There are a few threads about this so I'll let you search for them. Good luck.

I don't believe it would be the internal fuse as the red LED shouldn't turn on if this was blown.

Cheers...:D

This happened to me too with a regular, unlocked HTC TyTN (not the MDA Vario II from T-Mobile). Fortunately, after about two days, while I thought the handset is "dead", I tried to turn it on again and it worked, just like that. Weird :)
