Hi, Use a multimeter to check on the plug to see whether there is voltage coming out from the plug. If so, then it should be your motherboard problem. regards

Asus UL50VT always shows charging


Either your battery or the power cord has an issue. Does the battery ever fully charge and make the charging light disappear or turn green? If not the battery could be bad.

Try running the computer off the battery by removing the power cord. if the battery starts losing charging strength real quick then your battery is bad. I've see bad batteries that say they are 100% charged but as soon as you remove the power cord it gets down to 5% i a matter of minutes.

Try running the computer on just the power cord. If it stays on and lets you operate without any problem then the power cord is good. A good power cord will not charge a bad battery.

If the laptop does not let you stay on long with the power cord, then either the power cord is bad or the DC Power Jack where the power cord plugs into the laptop is bad. If either of them is bad they will not charge a good battery.

Check your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

No power or lights to toshiba nb205-n210 netbook


Maybe your motherboard is fried. If you know for a fact that the power cord is good and that the DC Jack on the motherboard is good but nothing is happening then the board is just gone.

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad.

Power light comes on but nothing happens


What type of laptop? What operating system?

Laptops don't boot for the following reasons: 1) Bad Power Cord. 2) Bad DC Power Jack where the power cord plugs into the laptop. 3) Static Charge Buildup. 4) Bad Motherboard.

The above 4 reasons are when you press the power button and absolutely nothing happens. You hear no fans running, no disk drive running, no one time clicking sound on the CD Drive and No light for a second or two when the CD drives click. In the case of a motherboard issue sometimes you will hear beep sounds or see blinking lights. Those beep sounds and blinking lights tells the technician what is going on with your motherboard and why it will not boot. If you see the blinking lights or hear beeps count them.

So you have a power light which means your power cord and dc power jack is good. So lets see if you have a static charge buildup.

Remove the Power Cord and the Battery from the laptop, then Press and Hold the Power Button for 30 seconds. After 30 seconds put the power cord back into the laptop, but leave the battery out. Press the power button to see if it boots. If it does you had a Static Charge Buildup and it's ok to put your battery back in. If it does not you more than likely have an issue with your motherboard.

Hello,

There are three possible reasons why your computer is experiencing this power problem. What you need to do is to isolate the component that's causing it.

These are the parts which should be checked:
1. Power supply
2. Battery
3. Motherboard of the laptop.

Here's the procedure that you have to follow:

1.
Remove the battery from the computer.

2. Power the computer up with the power cord only without the battery on it.

3. Check if it works perfectly without any problems even if the battery is out. If it works, then, the battery needs to be replaced. (Note: Batteries are disposable parts. They usually die after 2 years of usage depending on how you use it.)

4.If no go even without the battery on it, check the ac adapter or cord if there's a light lit on the box of the cord. If no lights on it, double check the connection. If connections seem ok but no power, then, replace the power cord.

5. If power cord seem fine, check the hole in the computer where you plug in the cord. What you need to check is if there are any sign of damages. Wiggle the cord and see if there are lights lit in the laptop.

I hope this help.

Not charging, green light on cord is lit up but wont charge


cthom10388

In regards to your notebook not charging this could be one of 2 things if your AC Adapter is showing a green light. Ether your battery is bad or there is something wrong with the charging mechanism.

If you are still in warranty I would call Acer about getting a replacement battery and/or motherboard because the charging mechanism is part of the motherboard.

Note another test you can do if you know someone that has the same model of Acer you can try your battery in there system. If their system charges the battery then you know the problem is not with the battery.

Hope this helps

Dell C400 Laptop Battery not charging


Go into the battery properties and check if the battery is charging. If it says it is, then test it, use the battery to see if it really is charging, they will sometimes give a false reading. If it's not charging, then check the power supply with an ohm meter for the proper output. If this all checks good, but the battery isn't charging, then I'm afraid you have a failed power management system on the motherboard. The power management system controls the charging along with other power related aspects of the machine. If the power management system has failed, then unfortunately, you will have to replace the motherboard in order to fix it.

If the docking station is not charging the laptop while docked, it may simply need to be plugged in using the power cord to recharge the battery.
