Notification Light Flashing Green/Amber
I had this happen to me the other day. The phone was extremely hot as well. I contacted HTC Support. Here's the reply I received. If this happens to me again I'll enter the code and check my battery temperature.

Thank you for contacting HTC Technical Support. I am sorry to hear that you can not find an answer for the flashing green and amber light.
The flashing green light means you have a pending notification. Flashing orange light means the battery level is very low. Solid orange light means that the battery is being charged. It just may be flashing because you have a notification and flashes back to orange because it is on the charger. Or it may mean that it is losing it's charge. Have you noticed anything like this?
You can take the phone and charger to a Verizon store and have them tested.
Having said this, we should check to see if the phone is overheating. The quality of HTC's products are of paramount importance to us. To ensure your phone is not overheating, please check the temperature of your phone via the onboard temperature gauge.
Dial *#*#4636#*#* A menu will appear. Depending on your android version, you may see some or all
of the following options.
Phone Information & Wi-Fi Information :
Please do not enter these 2 areas for any reason. Modifying settings in here can cause irreversible damage to your phone.
Battery Information, Battery History, Usage Statistics
These areas are safe to view, and have a variety of options including CPU usage, Network usage,
GPS usage, Sensor usage, Partial wake usage, and Other usage. You can then set the next menu to
a timeframe. Choose from Since last unplugged, Total since boot, and Total All time.
Within 50 degrees Celsius is considered normal and within the specifications of the phone,
meaning that the phone will function normally at that temperature. Over 50 degrees and the phone
should stop charging automatically. If your phone is going over 50 degrees, please contact HTC repairs: HTC RMA Center, 1-888-617-1113 (8 AM - 8 PM EST 7 days per week).
As for what happens when the phone is fully charged, once the phone reaches maximum charge it stops charging and starts using the battery life. The time at which the battery stays at [maximum charge] should be as short as possible. Prolonged high voltage promotes corrosion, especially at elevated temperatures. The reality is that the battery was only at 100% capacity for a brief moment, after which the battery management system allowed it to slowly dip down to around 99%. Leaving the phone plugged in overnight does not make a difference: the phone only uses the wall current to maintain a partial charge state.
I apologize for any inconvenience this may cause, and I thank you for your patience and cooperation while we help you resolve this troubling matter. As always, we are here to answer any technical questions or concerns you may have between 6am to 1am EST, 7 days a week for your convenience, or by phone at 1-866-449-8358. Please provide your serial number.
Let me know if I have successfully answered your question.
Sincerely,
Carol
