DC Jack diagnosis:
1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop.

Charger seems to have both red and green lites flashing at the same time no sequence and both batteries connected read 4.0 VDC, are these chargers repariable or throw aways


Your manual is here. The section on charging states, that green blinking means your battery is fully charged but blinking red means that your charger is faulty. I would say repairable.

1. Plug the female connector of the AC power cord (supplied) to the AC receptacle on the charger and plug in the male connector on the AC power cord into the wall outlet.

2. The On/Off LED indicator is blinking RED, this is abnormal. Unplug AC power cord from the on-board battery charger and wall outlet. Charger may need to be replaced. Contact an Invacare dealer or qualified technician.

3. When the On/Off LED indicator light is Off, charger is Off.

4. When the Charge LED indicator light is YELLOW, the batteries are charging.

5. When the Charge LED indicator light is solid GREEN, the batteries are fully charged (as their condition will allow).

6. When charging is complete, unplug the male connector of the AC power cord from the wall outlet and then unplug the female connector of the AC power cord from the AC receptacle on the charger.

You would be having one Power cord also with this Adapter.
Just connect the Adapter and Power Cord (Female and male connector) > AFter tht connect the Connector (Hole Side) to the Laptop for charging and the Second end to the Power Plug.

If still have any issues, Please feel free to mail @ guptapankaj8@yahoo.com

Power cord will not light up where it is inserted into the laptop unless you hold it steady. It will not charge unless it is held in a certain position. Is the male part on the cord bad or is it the female...


You'll need to get another power cord that is identical in power and polarity and plug. One can buy a generic power supply from Walmart that will power most laptops or Radio Shack (Walmart is probably cheaper).

Once the new power supply is obtained, try it, and if the same thing happens, then the problem is in the female plug connection to the motherboard of the Compaq Presario C762NR Notebook.

The Notebook will have to be disassembled and the female plug connection to the motherboard will have to be replaced.

If the male plug end shows any fraying or excessive bending signs, then I would definitely replace the cord.

It is difficult to determine which is bad, the male or female part without changing the easiest part... the power supply.

Also, you could go to your local Compaq dealer and ask to plug in one of their power supplies to your computer and tell them the problem that you are having, determining which is bad, the male or female part of your power supply.

Good luck on this repair.

I have an aqua vu scout and it has good battery and connection but no picture


mike if you are still having this problem, i figgured out how to fix it. i was having the same prob. so i cut the male conector part off the the camera cord and cut like 4" of the black cord part off to expose the wires. there will be 4 colored wires and 1 bare wire cut the bare wire off as close as you can to where you stripped off the black part, then expose the top inch of each color wire. OK now open up the back of the monitor, take the black female connector off you dont need it. you will see a 4 prong female connector part inside cut that off too, then conect the wires black - black / yellow - white / red - orange (i think it was orange) / blue - green . it sounds kinda complicated, but really easy, and now it works great! make sure you use electrical tape or something over bare wires

Garmin 650 won't hold charge in car -- same problem


Check power at the 12volt outlet to insure that you power is on at the connection. Try using a 12 volt convertor in the house to check the cord used in the vehicle.

Connections


The main connector to the power supply has to go into the motherboard. Its a rectangle shapped male connector that is on the end of the power supply that plugs into a rectangle female shaped connector on the motherboard. There might also be a shorter square male 4 pin connector at the end of the power supply that should connect into a 4 pin female connector on the motherboard.

After this then you'll want to plug the other connectors into any cd-rom, dvd-rom drives you may have. Same for a floppy drive if you have one. Also make sure your hard drive is hooked up. The connectors that you plug to these devices can only go in one way so no worries about hooking it up improperly. Hope this helps.

After all this, turn on the computer and then after you boot up into windows, make sure you go into my computer and verify that all your drives are being shown in there.

Missing part


Charger does't connect to DVD player.

Connects to battery. Built your own, Radio Shack, female to male jack, power supply from anything handy or spend $2 at thrift shop, $2 multimeter (Harbor Freight, Cheapo), junk variable resistor (pot).

7.4--8 V adjust. Or, get fixed value resistor dependent on PS voltage.

Charge anything,

And power supply for DVD house current.

Power Issue


sounds suspiciosly like your chord fitting is damaged(loose wires at connection)and shorting.if possible try a friends power supply with same connecter type before renewing cos could be faulty(loose)connection at pc(inside)constant pushing and pulling of connections often causes 1. loose split or disconnected wires at male connection or 2.loose pins on motherboard female connection or broken housing (not difficult to repair)more difficult to find out how to get to internal connection.

The Charger has a standard two pronged plug to go into the wall. The other end goes into the camera at the back bottom. You will see the female received for the male plug.
