Yes, you either need an adapter sold at most places like best buy, amazon, newegg, etc. or a changeover cable most likely available at those same places.

My compaq presario cq62 wont turn on i bought a new power chord but it still does nothing

Shane, new power cord? Does this mean the old one was bad?

Do I assume you used a multimeter;
1) To test the voltage output of the AC adapter (Charger),

2) And had an assistant gently wiggle the cable TO laptop, and power cord TO AC adapter; to see if there was an intermittent reading on the multimeter?

[The Center Hole on the plug end of the AC adapter cable TO laptop, is the Positive connection. The outer cylindrical metal shell of the plug, is the Negative connection.
You should be reading 18.5 Volts DC.

An economical multimeter can be purchased for as little as $5 to $12. Available in a multitude of stores. An auto parts store is but one example. I have seen them on the checkout aisle racks, of large discount stores.

The Positive (Red) probe lead is inserted into the multimeter, in the Red hole that has DC Voltage next to it. (DCV)
The Negative (Black) probe lead is inserted into the Black hole ( - )

The Function knob is set to DC Voltage. If just a symbol, the symbol is a dotted line over a solid line.
IF there is more than one DC Voltage scale, the Function knob is set to the 0 - 50 Volt scale. { 0 to 50 ]

AC adapter checks OK?
Then check the DC Power Jack.
The DC Power Jack is the jack on the laptop, that the cable from the AC adapter is plugged into. (DC_IN)

AC adapter removed, ('Natch), and Battery.
Use a No.2 pencil, and it's eraser, to see if you can gently move the Center Pin, in the DC Power Jack.
ANY perceptible movement means replacing the DC Power Jack.

However good news. The DC Power Jack is NOT soldered directly to the motherboard.
It is a DC Power Jack that has wires coming from it, and the wires end in a small white plug.
This assembly is called a DC Power Harness,

All you have to do is partially disassemble the laptop, unplug the DC Power Harness plug from the motherboard, and replace,

USE AN ESD wrist strap, and connect it's alligator clip to a good ground source.
I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.

You can also set a large metal serving plate (Unpainted), on the table you are working on, and connect to it.
Or a large metal knicknack. (Unpainted)

Use a mutli-compartment container for the various screws you will remove.
Label each compartment for the area the screw/s come out of.
SOME screws look VERY similar to other screws.
Advise do NOT mix them up.

(Just so you have it in case you need it for the future, )

AC adapter checks out, DC Power Jack checks out?
Check the Power On switch.

The Power On switch is pressed with the Power On Button.
The Power On switch is part of the Power Board,

This part separates the user from the tech. There are 6 wires in that flat cable. (I believe 6) There are 6 contact pins in the motherboard connector, for those 6 wires. TWO of those contact pins turn the laptop on. A tiny flat tipped Jewelers screwdriver, is used to MOMENTARILY touch the two contact pins.

{The Power On switch is a Momentary Contact Switch }

Laptop comes on you have a bad Power Board.

Laptop does not come on;

One or more Power MOSFETs may be bad, and may include bad Ceramic Capacitors (MLCC) for the Power MOSFETs.

Yes, motherboard replacement

Compaq Compaq Presario CQ62 white screen

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.

My compaq presario c795tu battery is not charging

Unplug the power supply, take a stiff tooth brush and clean the battery terminals in the laptop plus the battery, re-install the battery and plug the charger in, If that fails you need to find out if the charging circuits are putting out the proper voltage before you replace the battery.

Looks like your battery is having a problem. Remove the battery and replace after a couple of hours. If problem remains replace the battery with another to test, if this works, then the problem is with the adapter unit. Get a new one.
