The power cord for my laptop shorted and burned the end of the cord off near where it plugs into the laptop. Not sure what happened or why. My question is, would buying a new power cord be sufficient or do you think there is something wrong with the laptop that caused it. I'd hate to buy a new cord and then have it happen again. Should I have the laptop checked out first?

Check the AC adapter and power cord. It sounds as if either one end of the cord near the transformer box is loose, or the end that plugs into the computer is loose/not connecting properly. Failing that, make sure the wall socket you have the cord plugged into has power (try plugging something else into it). If everything I mentioned checks out, there could be something wrong with your battery.
What kind of adapter did you buy? Did it come with 5 - 10 different tips that you try on the end of the power cord until you find one that will fit into your laptop? If so, no wonder you're having problems, those things will burn your board out. AC Adapters have different power requirements (watts) If you have one that has changeable tips, but the watts are constant, you're asking for trouble. Stay away from those one size fits all Ac Adapter Power Cords
The laptop is either in sleep mode or the battery is low. If the laptop doesn't want to wake up, try unplugging the charger cord, then removing the battery (usually by sliding something on the bottom of the laptop to unhook it). Wait for 30 seconds then put the battery back in, plug in the charger and press the power button.
try without battery. if not work check the some burning smell near battery connector on laptop back. the thing is all the dv xxxx models have AC power controller chip burning problem .have a possible to repair that, if not need to repleace the main board.
Take a look at the back of the laptop. Is the gold power pin still there or is it now stuck in in the end of the power brick cord?
HP actually extended the wty on these machines because of the power pin issues. If the power pin is missing you will need to have the machine serviced. Out of wty, replacement power pins are easy to solder on the board if this is the issue.
If your pin is still there... Your AC cord or power brick may be the next things to check. Connecting them to a meter will tell you if there is power. Try moving the cords to check for shorts in the wires.
If your AC cord and brick are good, try pulling the battery. Your laptop can run off AC only. Batteries with bad cells can sometimes prevent the machine from powering up.
If its still not powering up after all of that, there may be an issue with the motherboard in the machine.
You First need to test your AC Adapter Cord...
You can test if you have a secondary known working one.. plug that one in to see if same issue occurs.. OR you will need to test the AC Adapter using a multimeter (available at any home improvement store for under $7).. When testing the Plug End on the AC Adapter - Hold The Negative Test Prod Of the Multimeter to the Outer Side Of the Plug Tip, and Put The Positive(red) Test Prod Inside The Plug Tip... See If You Have Power Through The AC Adapter Tip... You Might Need To Slightly Wiggle The Cord Near The Tip End To See If THere Is A Short In The Cord....
If Cord Tests Good....
You Will Need To Replace The Laptops DC Jack...
The DC Jack is the port where your AC Adapter Plugs into on the laptop..
Your Faulty DC Jack Would Need to be desoldered, the motherboard cleaned of all old flux, Re-Tin The Contact Pads and then Resolder a New DC Jack Onto The Motherboard...
These power cords are very sensitive and shielded. A bad power cord can have very serious effects and damage to the hardware of the laptop, especially the motherboard. They can be bought on E-bay and other sites for less than 30 bucks....beats a 300 dollar motherboard bill.
The inverter supplies high voltage to the CCFL lamp. Check the cables to the lamp, the lamp is located on the botom edge of the screen, there are two cables from the inverter to each end of the CCFL lamp. make sure they are not shorting out on any metal frame.
