Seem like battery or power supply problem,

as you think that there is only one laptop in the world - yours - you are mistaken...

for help you need to provide manufacturer and model and in case of computers - operating system as well...

SOURCE: no power through the laptop dell d6oo

There's evidently a short on the laptop's motherboard. Unless it's something obvious that can be repaired easily (and it'll still cost a lot for the labor to take the laptop completely apart and put it back together), you're going to have to get the motherboard replaced (expensive)or get a new laptop - depending on which seems more cost effective to you.

In any event, contact Dell.

Hello.

The most common reasons for power issues are the battery, power jack and power adapter/cord.

Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

SOURCE: i have a advent 7201.it will not come on on its own and it will not come on when the charger is plugged in.the green light is on on the charger but no power on the laptop.could it be the battery or th

Use a multimeter.

An economical unit can be purchased for as little as $8 to $12.
Available in a multitude of stores. An auto parts store is but one example.
Analog or digital is fine.

The Red probe lead is the Positive lead. Plug it into the hole with the red circle, on the multimeter.

The Black probe lead is the Negative lead. Plug it into the hole circled with a black ring., on the multimeter.

The center knob is the Function knob.
Set it to DC Voltage.
If just a symbol is shown, set it to the dotted line over a solid line symbol.

If there is more than one DC Voltage scale, set it to the 0 - 50 Volt scale.

The plug of the AC adapter (Charger) that plugs into the laptop, has a center hole, and an outside cylindrical metal shell.

The center hole is Positive.
The outer cylindrical metal shell is Negative.

Positive probe lead to the center hole, then touch the Negative probe leads to the cylindrical metal shell.

You should be reading 19 Volts, or VERY close to it.

Also have an assistant gently wiggle this cable, while you are testing.
Have them wiggle the power cable TO AC adapter, also.

An intermittent reading indicates a broken wire, or wires. Discard AC adapter, obtain a good one.

http://www.thelaptoppowersupplyshop.co.uk/advent-7021

The port on the laptop that the AC adapter (Charger) plugs into, is the DC Power Jack.

AC adapter checks out it's on to the DC Power Jack.
Post in a Comment if you wish to go on with the diagnosis.

My toshiba satilite L305D-S5940 Wont charge has new battery new power cord It comes on acts like its going to work then shuts off and sometimes wont come on What could it be please


Hi there,
1st : you can check from the power cable charge
2nd : check the adaptor charger if there is a light indicator or not, or you can check with multimeter to check the voltage on charger adaptor, does show the proper voltage for your laptop, you can check at the end of the connection that leads to the laptop.
note : Remember use DC current at Multimeter
3rd : if the adaptor running well, just plug on the adaptor charger to the laptop, dont turn on the laptop power, just see the light indicator with battery / lightning image on laptop, its explained that there is or is not the power current running to the laptop.
3rd.A : if its no power goes to the laptop then your adaptor charger is failed
3rd.B : if is there, there must be a problem with your motherboard, section power / power plugs, why do not want to charge with a new battery.
Conclusion :
- if the problem on number 1 & 2, then you can change the power cord and the adaptor charger.
- if there is problem on the 3rd.B then you can go to the toshiba services center for your problem.

thats all, hope its help.

How do i fix an Acer aspire 4730z that will not charge the battery and has the charge light no longer comes on, is the motherboard bad?


Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced.

When you plug the back in, does the display come back on or does the laptop need to be powered on again?

If you need to power on again, your battery is faulty.

Green light cuts off when plugging into laptop


Replace the charger, it probably overheat and died.
Try with a voltmeter to measure the output power (usually aroud 19 V DC)
Then the tricky part, try to power something else with the charger , something who might work with the output power (a car light bulb for exemple).
If it does work then you have a short cut on the motherboard of your laptop if it's the case replace the laptop, it's the hell of a job to repair the motherboard...
good luck

Have a Gateway Laptop Computer Model #MT6708. Previously computer had blank screen and no power. Currently purchased new battery and power cord. Computer now operating screen and power is on. However, when...


First thing check that the battery charge light is on when the battery and the charger are connected.
If it is it indicates that the power supply is charging the battery,
If it isnt it may indicate a fault with the battery or that the charger is not compatable with the laptop or that there is a fault with the charger.
If the battery is charging then try running the laptop on battery only without the charger and on charger only without the battery.
This will eliminate which one is faulty.

You mentioned that if you wiggle the cord then the light comes on again.
Check to see if the charger end plug is lose or the actual port on the laptop is lose.
If the charger plug is lose then return to seller and make sure they gave you the correct charger. if the actual port on laptop is lose then perhaps u got a bad connection and you need electrician or local laptop technician to open it up and solder properly on motherboard.

Let me know how it goes.

Laptop died!!!


THe power controller in a laptop manages both AC power and battery. A laptop can power on without a battery as long as it is connected to the charger. That's because both battery and AC power have same power specifications. If the laptop fails to power from AC charger, then you may have an internal hardware failure. If no LED's flash, no light and no noise is made when you connect the charger, the problem is most likely to be a simple one, a faulty connector or something like. First of all, please specify me, what laptop model you have, and, exactly, what does it do when you connect the AC charger.
