Ihave a samsung computer series & 700G7A/700G7C I need to know where I can buy the battery A"C adapter and the power cable.I have also the number NP700G7C-T01CA

you DON'T charge the camcorder with the usb cord,you only move files between cam and computer,you need a power cord that plugs into the wall,see pic, LETO 2A AC Power Charger Adapter USB Cord For Panasonic HC V100 HC V500 HC...
ihave the same camcorder,

This problem, from your description, is very unlikely to be because of a change in your settings, if nothing happens when you try to turn your computer on.
If no power is being supplied to your computer - no lights come on - then
you might just have the combination of a flat battery and a faulty power adapter. You must test the power adapter (measure the output voltage with a voltmeter) or obtain another one (preferably temporarily/borrow) to see if your computer will turn on with that. If your power adapter has failed it must be replaced. If still in warranty, Samsung or your retailer/dealer should replace it at no cost. (you should not attempt to repair a power adapter)
Otherwise (or even as a first step) I suggest you contact Samsung support by email or Live Chat (details are on this
http://www.samsung.com/in/support/model/NP-R428-DA01IN
webpage.) Please have your computer's model number, serial number, operating system and other details to hand (the numbers
can be often be found on labels on the case of your PC)

Check when you turn it ON if you would see the keyboard lights or the CAPS lights respond. If they do, then the unit is ON but your LCD could be defective. Try using an external screen if that is the case.
In case there is really no power coming in, you will need to try and get a hold of a new/spare power cable/adapter and test with it.

Also, try removing the battery and use the laptop with just the power cable.

See the link below on how to remove the battery. Samsung Series RV510

Zinzee, check the AC adapter first. (Charger)
Wiggle the power cord from AC adapter to surge protector.
See if the AC adapter LED power on light, blinks.
Yes? Bad power cord.

No change?
Go on.

The port on your laptop that the AC adapter plugs into, is the DC Power Jack.
Wiggle the cable from DC Power Jack to AC adapter.
Power On LED light up, or blink?

Change? New AC adapter. (Also need to check DC Power Jack center pin, to ensure problem is cable, not DC Power jack)
No Change?
Go on.

Unplug the AC adapter from the surge protector. You will need a multimeter now.
An economical multimeter can be purchased for as little as $5 to $12. Available at a multitude of stores. An auto parts store is but one example. (Not for $5 probably )

The Function Knob is set to DC Voltage. (DCV)
If just a symbol it is a dotted line over a solid line.

The center hole in the plug of the cable that goes to the DC Power Jack, is the Positive connection. This is where the RED probe lead (Positive), of the multimeter goes to.

The outside cylindrical metal shell of the plug is the Negative connection. This is what the BLACK probe lead (Negative), touches against.

You should read very close to 19 Volts (DC)

Have an assistant wiggle the AC adapter cable to DC Power Jack.
AC adapter is good? No intermittent reading on multimeter?
Go on.

Remove the Battery. Take a No.2 pencil, and use the eraser to GENTLY, see if you can wiggle the center pin around, of the DC Power Jack in the laptop. (DC_IN)

ANY perceptible movement means a problem with the DC Power Jack.

Chose link for the 4 views of the DC Power Jack.
Underneath the large Main view, there are 4 smaller views. Click on the one all the way to the right.
This is a view of the Back of the DC Power Jack, and the side that faces in on the laptop.

Note the L-shaped prongs on each side of the jack. These go down into the motherboard, and are soldered to the motherboard.
The 3 vertical lugs you see on the back, are the power, and Ground connections for the jack, and are also connected to the motherboard.

1) The center pin of the jack mounts to the jack's body, like a rivet. It is squished on the back, and this holds it in place.
Very easy to break that mount, and loosen the center pin.

2) The connections on the back are soldered, as previously stated, as are the 'L prongs' on the sides. Solder connections are also known as Solder Joints. If the jack moves with the pencil, and it seems to not just be the center pin, one or more of these solder joints could be cracked. (Broken)

Number 1 above means P-r-o-p-e-r-ly removing the DC Power Jack, and properly soldering a new one in.

Number 2 above just means re-soldering cracked solder joints.

DC Power Jack proves to be good?
Go on.

At this point those who use the moniker 'Technician', but in reality aren't a tech, will want to replace the motherboard.
In reality the Power MOSFET's should be checked, to see if they are good.

IMHO a $4 to $5 P.MOSFET (Or two of them), is much cheaper than a $200 motherboard.
Of course if there is $125 to $150 in labor, the savings isn't that great.

Buy an ESD wrist strap, connect it's alligator clip to a good ground source, remove the motherboard, buy the DC Power Jack, and take both to the tech. Should be about $50 labor, or less to replace the Power MOSFET/s. (May not be both of them, just one)

[ 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 tray (Unpainted), on the table you are working on, or a large metal knickknack (Unpainted), and connect to it ]

No Zinzee I do not know what manufacturer, and manufacturer number, of P.MOSFET's are used on your Samsung.
I DO KNOW;

1) They us J-leads on the bottom.

They are located near the DC Power Jack on the motherboard, usually. Example using HP dv6000 and dv9000 series laptops,

If your computer has a USB-slot or a PCMCIA-slot, then it is capable of using a USB-to-wireless adapter stick, or a PCMCIA-to-wireless adapter-card.

Look on eBay -- find the model-number on the current battery, and search on eBay, being sure to search both "body" and "title" of eBay listings, to find "compatible" batteries.

There should be a reset either hard,"button" or soft, Plug in the computer and run any software that came with it, Please let me know how you made out, I have been wanting to run my pc movies into my Sammi at the other side of the house, but most of the products I looked at have spotty service at best, There is a new one at Best Buy , that does live streaming in hdmi if you already have the adapter, for lie 60-70 dollars, I will await your response,

This is an old type of PC speaker system. Can it be powered by batteries. How many batteries needed??
Multiply the number of batteries by 1.5 volts and you
get the voltage rating of your needed adapter. You can also take a look at the back of these GE speakers. Maybe you can find the voltage rating.
You may also consider buying a new set of PC speaker that can be plug direct to your power outlet.
You can buy it at a cost slightly higher than your
needed adapter.

Plug the AC Adapter into a Known-Good Wall Outlet Verify the wall outlet is known-good by testing it with another device, such as a lamp. Confirm there are no power strips, surge protectors, or uninterruptible power supplies (UPS devices) connected to the power cable. UPS devices provide temporary power for a computer when there is no electricity available from the wall socket, such as during a power outage. Plug the power cable into the known-good wall outlet. Power up the system. Replace the MiniPCI Door, Rubber Feet, and System Motherboard

For charging your Samsung L201, you need the ac adapter (part number AD44-00131A, style SAC-47) and the 20-pin usb cable (part number AD39-00147A, style SUC-C3) both of which can be ordered at www.partstore.com

Ok well the Power adapter is not really that special.. what you need is a Centre Pin POSITIVE 12volt at say 4 amp power supply unit. I would get it from Ebay.. perhaps even being able to get an exact one from Ebay.. Othewise try the Samsung site and purchace direct. Look here for an idea. http://shop.ebay.com/?_from=R40&_trksid=m38&_nkw=power+supply+for+LCD&_nd1=See-All-Categories
