Hi
you can customize your power management in windows by:
1- right click on an empty place on the desktop.
2- Select Properties, then select Secreen Saver, and click on Power.
3- You now get access to The Power Options Properties where you can change anything you want.

If you want to change the voltage level, you need to move the button on the AC/DC device to the right or the left. But! be careful, high voltage can cause your laptop to cut off. So, alwasy try the level under the one you using now.

My computer toshiba is not turning on


6 - SUGGESTED SOLUTIONS

I would like you to read that part. Means somewhere, someone, (Staff?), has taken it upon themselves to attach previous solutions, to your posted problem.
(They do it with my previous solutions given, also)

I have seen, "Gary Oldman plays the Bagpipes for You", and, "20 Ways to Knit a Cardigan Sweater"; given as solutions in the computer category. Guess you should feel special, that the suggested solutions even come close.......lol!

A) Nope. It is NOT an obvious 'board issue'. (Reference is to the motherboard)

B) Screen turns Black means a problem with the screen.

Really? (You're going to post that on a the world's largest product support website, and with REAL technical experts in this field looking on? Yeah,...Right!)
(....after all these were done, you must definitely get ride to this mura.......!O_O! What does THAT mean????????????)

Moving on.............

DIAGNOSE

Leave the guessing to those who like to play games.

("I bet aliens in the middle of the night, came down and put a virus in your laptop. If just the LED light on the 'charger' lights up, you know you've been had! Put a tinfoil hat on to protect yourself!")

1) The 'charger' in reference is an AC adapter. It converts the AC electricity from your home, or business; into a low DC Voltage.
(Can also be said as low DC electricity)

The LED light on the AC adapter, is an indication the AC adapter IS receiving power.
NOT an indication the AC adapter is working.

AC adapter is tested with a multimeter. See if it is putting out the correct voltage.
On the AC adapter in a label, is the Input voltage, and the Output voltage.
Example: Input: 100 ~ 240VAC @ 50 ~60Hz
Output: 19VDC @ 4.34A

Means the AC adapter can use AC electricity, that is from 100 to 240 Volts, and either 50 Cycles per Second, or 60 Cycles per Second.
Hz = Hertz. Hertz stands for Cycles per Second

Output is 19 Volts DC, and at 4.34 Amperes
The number to be concerned with here is the 19 Volts (DC)
19 Volts (DC), or VERY close; is what should come out of the cable, that plugs into the laptop.

Also suggest have an assistant gently wiggle the cable, that goes from the AC adapter TO the laptop.
If there is an intermittent reading on the multimeter, this suggests there is a broken wire in that cable.
Same procedure for the power cable TO AC adapter.

Not feasible for you, then take to nearest small computer shop, and have the resident tech check it out. Should only be a couple of bucks.

Tech indicates it's bad, has a new one, or universal one they will sell you? I think I would take my old AC adapter, and leave. May be on the up and up, may not.
If it is said that the AC adapter is bad, and you can buy a universal one almost anywhere; THEN I would tend to believe the person.

AC adapter needs to be working, and correctly. (Proper output voltage)
Charges the Battery, and also can power the laptop by itself.

2) DC Power Jack:
The DC Power Jack is the jack on the laptop (DC_IN), that the AC adapter plugs into.
If there is a problem with this jack, the laptop will not receive power.

There are various styles of DC Power Jacks.
Most common is the style, that has a large Center Pin in the middle.
AC adapter removed, Battery removed; a small object is used to GENTLY see, if the Center Pin can be moved.
ANY perceptible movement of the Center Pin, indicates replace DC Power Jack.

With the older style of laptops, the DC Power Jack is soldered directly to the motherboard.
With the newer style it is not.
The DC Power Jack has wires coming from it, (Cable), and they end in a male plug connector.
It is now referenced as a DC Power Harness.
Much easier to replace, than the old soldered on version.

3) Bad Power On switch.
It's a small carbon button switch, and they do go bad.

4) All of the above checks out, then the problem is the 'board'.
Motherboard.

More specifically small electronic parts on the motherboard, have gone to the 'Great Electronic Parts store in the sky'.
(How's that for technical? lol!)

Usually Power MOSFET's on the motherboard.
Many people then replace the motherboard. Some of us do not.

Using the HP Pavilion dv6000 series, and Pavilion dv9000 series; of Notebook PC's for an example,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

Here we see the Fairchild Semiconductor Industries - FDS6679 - Power MOSFET, and Alpha & Omega Semiconductor LTD - AO4407 - Power MOSFET; is being used.

Both are Obsolete now, but there are cross-reference examples given. FDS6679 cross-reference example,

http://www.mouser.com/ProductDetail/Fairchild-Semiconductor/FDS6679AZ/?qs=sGAEpiMZZMshyDBzk1%2fWi1qxDdW%2fXBi2qgMuZEfLVO4%3d

One dollar and one penny - USD

http://www.youtube.com/watch?v=3NN7UGWYmBY

Price of replacement motherboard? Averages from $50 to $250
Also add labor cost.

HOWEVER, there is more information that I need from you;

1) You indicate, "The screen does not turn on at all. It has no light but the charger light is the only light that turns on."

Meaning ONLY the AC adapter's Power On LED lights up?
No Battery LED light on the laptop?
The small fan is not running?

Makes a BIG difference if the fan is running.

Also post the laptop manufacturer, and model number.
The model number is on the Bottom of the laptop.

Using Compaq and HP laptops as an example, post the Product Number.
This is P/N in the white Service Tag, on the bottom of the laptop.

Post back in a Comment.

Problem with HP 8510q laptop charging. Charging not working. Laptop working only that time when i have power in battery. Charging light not show. I try other charger but same problem. Is it inside some...


Inside? Yes. (If 'charger' is good)
Fuse?
No

Diagnostic flowchart:

A) AC adapter (Charger), has to be KNOWN to be good, before going on.
Used on a working laptop to see, or multimeter is used to check Voltage (DC)

The plug end that goes to the laptop, from the AC adapter, has a Center Hole, and a cylindrical outside metal shell.

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

The Positive (Red) probe lead of the multimeter goes to the Center Hole, and the Negative (Black) probe lead of the multimeter, goes to the cylindrical outside metal shell.

You should be reading 19 Volts DC.

Also have an assistant gently wiggle the cable FROM AC adapter TO laptop, and the power cable TO AC adapter.
If there is a fluctuation on the reading, there is a broken wire, or wires, in one of those cables.

B) Check the DC Power Jack.
This is the jack on the laptop (DC_IN) that the AC adapter plugs into.

Has a Center Pin, and an inner cylindrical metal shell.
Battery removed, use an eraser on the end of a No.2 pencil, and see if you can GENTLY wiggle the Center Pin around.

ANY perceptible movement of the CENTER PIN, means replacing the DC Power Jack,
(By the way, is it an 8510p, or 8510w?)

http://www.alldcjacks.com/en/ppj052-laptop-dc-power-jack.html

Any movement of the rest of the DC Power Jack (Body), means replacing it; or may just mean the solder joints are cracked, and can be re-soldered.

C) AC adapter and DC Power Jack checks out?
Problem may be with Power MOSFET's on the motherboard, and associated MLCC's.

(Multi-Layer Ceramic Capacitor, and they are SMD/SMT just like the Power MOSFET's.
Surface Mount Device/ Surface Mount Technology)

Using HP pavilion dv6000 series, and Pavilion dv9000 series Notebook PC's, for an example,

No power on my samsung 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.

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.

How do i change out the charger port of my gateway p-6301? I believe this is the issue... I have tried replacing the battery and power cord, but it still will not detect that the cord is plugged in.


Hi,


Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.


1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.


Hope this will help...Thank you for using Fixya...

Advent N270 netbook will not charge. Orange light comes on initially then goes off. Also when I wiggle the plug into the laptop the light flashes on and intermittently.


It sounds like either a bad connection on the motherboard or a broken wire in the adapter making intermittent connection.

1. With the power adapter disconnected, do you have a power light? This would indicate the adapter is good and the plug is questionable.

2. Check your power adapter output with a multi-meter.(be sure to wiggle the wires around) If the power fluctuates, replace the plug.

3. If the power is solid, replace the motherboard connector.

Battery wont change


A problem is just like a mountain. You don't jump over the mountain, you climb it in steps, one step at a time.

1.How old is the battery? 1 to 2 years old, you can expect it to be at the end of it's Life Cycle. Batteries are rated in so many hours of usage.
Best bet is to let the battery charge 24 hours, then try it.

Would be nice if you someone else that has an Inspiron 1525, and they would try to charge your battery. If it doesn't charge up, you would know it's the battery. If it does charge up you can move on down the charging system, to try to find the problem.

2.AC adapter, (Charger) If you have a multimeter, set it to the 50 volt DC scale.
Laptop and desktop computers use DC current. (Direct Current) Your house, for example, uses AC current, (Alternating Current)
AC is converted to DC by the AC adapter, (Charger)

An example of DC current are flashlight batteries, and your laptop battery.
DC current has a Positive pole, and a Negative pole.
The center pin of the plug of your AC adapter is the Positive pole. Any of the four outside pins on the plug, are Negative.
The Red, (Positive), probe of the multimeter goes to the center pin. The Black, (Negative), probe goes to any of the outside four pins on that plug.
Example of a DC Power Jack, for the Dell Inspiron 1500 Series of laptops, 1525 and 1526, (This is the jack inside your laptop, where you plug the AC adapter into),
http://www.megaemarket.com/dc-power-jack-for-dell-inspiron-150150015011505.html

3.It may be that DC Power Jack itself is bad, or one of the solder connections is cracked. It's hard to see it clearly on the link I provided, (So I Right-clicked on it, Save Image As, and put it right in my My Pictures folder. Then I magnified it), but in the photo you will see some metal pins sticking out of the rectangular body.

The metal pins are sticking up. In reality those pins go down, when the jack is mounted on the motherboard. They go through the motherboard, via holes, and are soldered on the other side.
It is these solder joints that may crack, is what I'm referring to.

Solution to 1?
Obviously buy a new battery.

Solution to 2?
If your multimeter findings show lower voltage than needed, it's time to buy a new AC adapter. They have generic ones that can be used on a variety of laptops. The voltage will be stated on the top of the AC adapter.
Example: 19.2V-1.0A
That's 19.2 Volts at 1 AMP.

It may just be the plug end on the AC adapter itself. The plug end that goes into the DC Power Jack, on your Inspiron laptop.

Solution to 3?
Unless you are a skilled Electronics Technician, and have Excellent de-soldering/soldering skills, I advise taking it to a computer repair shop. It may not just be cracked solder joints. The DC Power Jack may need to be replaced. Maybe the motherboard is one of a bad design, and where the DC Power Jack attaches to it, has cracked.

No ac power but plugged in


If you plugged in the ac adapter, and you still get no power and cannot turn it on, the first thing to check is the AC adapter. Get a voltage meter, set it to 200 DC, put the positive on the inside and the ground on the outside. Unless you have a highpower alienware laptop, it should read +/- 20 V, most likely 19.xx. If your AC adapter is good, then the DC jack, what the adapter plugs into, is bad. In this case, the laptop will have to be disassembled, the mother boared removed, the old DC jack de-soldered and taken off, and a new DC jack soldered on. You would really need to take it to a qualified techninician at a shop to di it.

Toshiba satelitte adapter went bad ordered new one it wont work


If the old one works you have another power supply or wrong one.
Check the properties of your power supply.

Related to your issue you also may consider this:


1.- Computer AC / DC cable is bad not allowing the computer battery to charge.
2.- Battery is bad.
3.- Battery charger board is bad.

Solutions:
1.- Computer AC / DC cable is bad not allowing the computer battery to charge
Verify that the AC and or DC cable is not bad by testing the computer only with the power plug connected and the battery out of the laptop.
2.- Battery is bad
It is possible that if the power plug is good that the computer battery is bad. Leave the computer connected to the power with the battery connected in the computer for at least one hour; if the battery does not charge, consider having the battery and/or the laptop serviced or repaired.
If the computer and/or battery is not in warranty consider just replacing the battery as it is very likely that it is just a bad battery.
3.- Battery charger board is bad
If the battery has been replaced or an alternate battery from an alternate identical laptop does not work in the computer, it is likely that the power or charger board within the laptop is bad. It is recommended that the laptop be serviced or repaired.
