laptop battery is more than 3 - 4 years old then the battery could be worn out.
Rechargeable batteries have a finite number of charge and discharge cycles and
will lose their charge capacity over time, i.e. won't charge to 100% and
gradually the charge reduces until the battery won't charge up at all. OR The
battery shows a 100% charge but when the adapter is disconnected the battery
drops off to zero capacity in a very short time. If the battery drops to an
unacceptable charge level then the battery needs to be replaced.
Rechargeable batteries will fail if stored in a discharged
state for long periods.
It sounds like the charging port on your phone is broken. This could have happened a number of ways. Either by dropping your phone, putting the charger in wrong, or taking it out wrong. If you call HTC(866-449-8358) and it is still under warranty they will probably fix it for free as long as it doesn't have any water damage(http://www.ehow.com/how_4479971_check-cell-phone-water-damage.html). Otherwise you could also get a new phone.
If the laptop works only off the Power Cord and the batteryis not charging, then the battery is dead.
To check to make sure the Power Cord is working remove the battery and let thelatop run for 10 minutes or so.
To check to see if the battery has any charge left in it put the battery in andremove the power cord. If it won't boot or shuts down then the battery is deadand needs to be replaced if the power cord is ok.

Your problem is far more than the battery. Your problem is the power cord. Laptops for the most part will work off the power cord even if the battery is dead or even if the battery is not in the laptop. Your power cord charges your battery and if it is bad it will not charge it. You've been working off your battery even though you might have had the power cord plugged in, but if it's bad and not charging the battery, the battery drains and then you can't get the laptop to power on at all. Go purchase a ac adapter and power cord that is designed for your system. Don't buy one that some of the big box stores sell that has a an interchangeable plug at the end designed to fit just about any laptop. Those will eventually burn *********** board out.
Have you attempted taking the battery out and while the battery is out holding down the power button for a few seconds? If this doesn't work, First test your charger to ensure proper charging. Clean charging ports. Remove battery and clean brass contacts with alcohol and q-tip
Depending on how long you've had the player, the batteries may need replacing.
I have seen a problem where the computer would not recognize the player and would not charge it, however.
First, I recommend trying to charge it directly from the computer USB port (not the hub) if possible. If that doesn't help, try reinstalling the software for the player to see if the computer will then recognize it and allow charging.
If neither of these fix the problem, it's probably time to replace the batteries.
You may have a hardware problem. It's very common for the charging port in a cell phone to become damaged somehow, which can cause this error. Other possibilities is a damaged battery or damaged power cord. Your best bet is to bring the phone to your carrier's nearest store and have them check it out for you. If it's the battery or the cord, a simple replacement is cheap and quick, but if there's a problem with the phone itself, you'll need to get a new one.
Possibly a failed or damaged charging port (does it feel loose)? After that, charger may not be chucking out the voltage (19.5 volts)? Test with multimeter set to DV volts, with one probe on the inside of the plug ant the other on the outside.
Does the charger LED light blink when connected (sign that power is not making a circuit)
If the above fail to work, then the problem is with the connector on the mobo, this may just be a Charger port needing replacing (wired or soldered version), or the charging circuit of the motherboard gone
