I apologize for the inconvenience you're experiencing with low volume and the unlock/power buttons on the Incredible 2. I will be more than happy to assist you with this issue. Due to the issues on the phone, I would first recommend to perform a soft reset. This is done by powering down the phone, remove the battery for at least 30 seconds, replace it and restart the phone. This will clear the cache on the device.
Make sure you are not using a task killer on your phone. These can interfere with the processes that the phone needs to connect to the network. They are also known to cause instability to the Sense UI on HTC devices, causing the phones to behave abnormally. If you use a task killer, we strongly suggest that you uninstall it.
Next verify that sound setup on the Incredible 2, select All Apps > Settings > Sound > Verify the sound levels.
Also, if you have a case of any type on the phone we recommend to remove it. Cases will often impede proper reception and functionality of the phone.
Lastly I would recommend to boot the phone in safe mode for testing purposes. First verify that Fast Boot is not enabled, select All Apps > Settings > Applications or Power > Make sure Fast Boot is not selected. To enable safe mode:
1. With the device turned off.
2. Press the power button.
3. Once the device turns press and hold the volume down, once you see the splash screen (HTC quietly brilliant).
4. Press and hold the menu button (DO NOT RELEASE THE VOLUME DOWN).
You will know it has worked because the device will give a brief vibrate or 3 quick vibes. Once it loads you will see on the “Safe Mode” on the bottom left of the screen. This disables all 3rd party apps and drivers from launching. Use the phone normally for 24-48 hours like this. Do not use 3rd party apps or install from the market or the test will be inconclusive.
Unfortunately if there are physical issues with the power button, I would then recommend contacting your provider for warranty the store provides. In most cases your device can be repaired or replaced through the provider. If they are unable to assist you, you can contact our HTC Repair/Warranty Department at 1-888-617-1113 (8 AM - 8 PM EST M-F).
