It is not ok if there is no DC voltage to the plug, probably a broken wire, go to best by and buy a unversal power supply for your laptop, take the old one with you to match it up.

Hi, i have svoa labtop and now my charger adapter got burnt due to electrict short. Now my charger is not working and i cannot use it.


OK. But I don't understand what the problem is.

AC adapter (Charger) is burnt out, by a new one.

Look at the old 'charger'.
Look at the label.

Input: 100 ~ 240VAC/50 ~60HZ.

100 to 240 Volts AC, at 50 to 60 Hertz. (Cycles per Second)

Output:
This is what you need to know.
What is the output voltage of the original charger?

Example;
Output: 19VDC @ 4.63A

19 Volts DC at 4.63 Amps. (Amperes)

Your charger MUST put out 19 Volts. (For the example)
It WILL be DC electricity, so don't worry about that. (Direct Current)

[Your 'charger' is more than that. More than a charger for the laptop battery.
It is also a Converter. It converts the 100 to 240 Volts of Alternating Current, (AC), into a low DC Voltage.

Plus it charges the Battery, WHEN needed ]

Post back in a Comment as to what the exact query is.

R519 move ac power cable light flicker on/off


This could be an AC adapter problem.Use another same rating adapter for teating.Check your ac adater volt and ampere at output terminals using a good quality digital multimeter. If OK, check the battery also. Then only suspect motherboard and power jack. Hope this helps

THERE IS A LONG TIME AGO SINCE I DONT WORK WITH MY MICROTEST PENTASCANNER AND I DO NOT KNOW IF THE AC ADAPTER HAS AN OUPUT OF 9.VOLTS I AMP AC OR 9 VOLTS 1AMP DC PLEASE TELL ME WHICH IS THE RIGHT AC...


An AC adapter should output DC. The device should say next to the power plug what voltage input it requires. Also, check the AC adapter, it may say something like "Input 110-120VAC Output 9VDC".

Vocalist live 2 problem. power to unit OK , lights up. Guitar output OK. No tuner, no vocal output.


NO power light or audio from Digitech Vocalist 2 live. Check that your power adapter is for 9 Volts AC (not DC like most pedals) and is rated at 1300ma or more. A DC adapter MAY light up the unit but not make it pass audio. Lights can be lit but that is NOT an indication thaat correct power is applied. They likely use the AC input to generate both positive and negative voltage within the unit. The use of a DC adapter will prevent generating one of these required voltages and prevent audio from passing.

Can a nx9110 charger /ac adapter work on an ibm thinkpad t30


Thefollowing three conditions should be met for you to use a charger safely. 1)Output Voltage is within +/- 5% of your old charger's output.
For example, ifyour old charger provides 19.5V, then you can use a charger that provides 20.5Vor 18.5V.
2) Output Current is the same or higher than that of your old charger.
For example, ifyour original adapter provides 3.42 Amps, then you can use a charger thatprovides 3.42 Amps, 3.9 Amps or higher.
3) Connector tip must fit securely into your laptop. Pleasecheck carefully before using nx9110 adapter on t30.

Vgn fs 980 adapter how to tell if it is not working


AC adapter? Test the output voltage.

Use a multimeter.
Stores like Radio Shack, Walmart, and auto parts stores, for a few examples have cheap one's you can buy.
About $12.

Set the multimeter knob to DC volts, and the 0 to 50 Volts scale.

The middle hole of the AC adapter plug is the Positive connection. This is where the Red lead goes.

The outer shield of the plug is the Negative connection. This is where the Black lead goes.

Look on the AC adapter for the OUTPUT VOLTAGE
(Not shouting)

Example:
I'm looking at an AC adapter for an IBM Thinkpad 370, right now.

INPUT: 100V 50-60Hz 130A
OUTPUT: 18V ~~~3.36A

The Output voltage is 18 Volts
The Output Voltage of your AC adapter should be close to this.

Use Sony ICF-C1IPMK2 in Europe


A transformer type (Linear Mode Power Supply) AC to DC power adapter with a 9.V nominal output, measures about 12.V without load when tested with a multimeter. A power adapter with a nominal output of 7.5 V, measures a little over 9.V. Considering a number of people across different forums reported the adapter's measured power output as 12.V, I think the nominal rating of the AC to DC adapter should be 9.V. However, keep away from Switch Mode Power Supplies.

After you have verified that the solder is good around the DC Jack >>>>

Check MOSFET (Anachip 4407 or Fairchild 4435) near DC JACK
