M8 Not booting, battery problem?

[Drowzz]

Hi Guys,

Strange problem here.
My M8 does not respond to any button combination at all.
But when I plug in the charger, the red LED Light comes up, the battery icon comes on the screen, the red LED gets brighter, and then everything goes black and the process starts again.
I was wondering if any of you guys experienced this, or know what this is? It suddenly happened.
I was thinking of a problem with the battery, but not sure?

M8 is running the latest insertcoin.

Charge the phone for several hours (overnight) on wall charger (not connected to computer). Then hold power + vol up button for a minute or longer, and see if any change (even if it's just the HTC logo screen). Folks often don't realize you need to hold the buttons what long in certain "stuck" situations, including battery drained/power off. That includes myself, I thought my M8 was bricked some months ago, as I was simply not holding the buttons long enough.

Thanks for the reply. Tried that already, but will try again later today. If there are more suggestions, always welcome.
