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.

http://www.amazon.com/POWER-SOCKET-CONNECTOR-SAMSUNG-SERIES/dp/B008AGK43O

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.
Examples,

https://docs.google.com/viewer?a=v&q=cache:oER5NNz8cwcJ:www.fairchildsemi.com/ds/FD/FDS6675BZ.pdf+Fairchild+FDS6675BZ&hl=en&pid=bl&srcid=ADGEEShOhWPjm_M-ROHme4iEMrztCTOd-28jNiy1hVLQQh_VOyv8zcXEVDB_iTQA6MuZO88UmRkDgjyW9j4CP2aIJ-4DS-h6JNM3lvxldeApQeecmz_DADCw1s7tmNLxfPknqX14SZP6&sig=AHIEtbS_rYUAeo_8rB9YHkW05ZjLqeH4Jg

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

You say it isn't charging, but will it run off of AC power? If it isn't getting *ANY* AC power, then it might be the female end of the power jack on the laptop. If it will run on AC, the culprit is likely to be a battery that needs replaced.

Hi,
Good day. You can try to do these steps which is usually a normal solution to this kind of issue:
1. Take out the battery of your laptop
2. Remove main supply, or power cord
3. Hold power button down for 30 secs,
4. Put only power supply in or power cord
Note: do not put battery in yet
5. Turn laptop on
6. Put the battery in.

If this will not work you might consider contacting toshiba tech support for laptop for other resolution. Hope this information will be helpful in resolving your issue. Thanks for using fixya and have a great day.

SOURCE: Toshiba Satellite C655-S5082. Won't power

Hi.

Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.

If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.


Good luck.

Rv510 plugged in but no lights on my laptop


You need to check all of these: 1. External charger, 2. Battery, 3. Internal charger, 4. Software. First, check if the battery is fully charge (or more than 80% charged). Second, use a tested good working battery charger/ac adapter to test your ac adapter (go to local electronic stores and test your laptop with their ac adapters). Third (if your ac adapter and your battery are good), then check your Power Options (click Help and search "power option" if you don't know where it is). If the Power Options is ok, then your motherboard (internal charger) has a problem. You need to bring your laptop to trusted local laptop repair shop.

Samsung rv510 charging port


The laptop needs to be dismantled completely to get to the motherboard and the charge connector. The connector maybe OK and only needs to be re-soldered to the motherboard. If you do not feel you can DIY, then take it to a computer repair shop.

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

My 65" samsung turns off when i connect my laptop


Hi Spence,
Is the TV set to "VGA"? If the TV does not detect a signal, it won't stay on, only go to a sleep mode. Make sure the cable is securely connected to the TV as well. You may go to the settings and check the power saver settings, but I don't think this has anything to do with it, I only offer it as another avenue to pursue.
Best luck
