SOURCE: Laptop AC Adaptor

If the light is going out whenever you plug the Ac adapter in you most likely have a short in the laptop. The most likely culprits are a failed battery or a damaged AC port. Remove the battery and AC the use a pen or pocket knife to wiggle the pin in the center of the AC port. If it is solid, it's probably good, if it wiggles it's likely broken(may need a pro for this repair).

Assuming it's ok, leave the battery out and try plugging the AC back in. If the light goes out the problem is likely on the motherboard and may need a pro. If the light on the AC pack stays on turn on the laptop, if that works the battery is the problem, you can purchase a new battery.

Try these and let me know how you make out,


Chris

SOURCE: wont operate on battery

You will definitely need to replace the ac adapter. I had a similar situation & replacing the adapter with a new one solved the problem.

SOURCE: ac adaptor crackling thru external speakers

Allan, It sounds like you have what is called a ground loop. A ground loop can occur when two pieces of equipment are connected together through a home or buildings safety ground through the same power source. For instance, your PC is connected to a power source through the AC adapter or plug, and your external powered speakers are receiving power from the same power source. The surrounding cables as well as the AC adapter(s) can act like an antenna. This will cause a low hum or crackling that would be audible through the speakers or headphones.

You may want to try plugging all components into a power strip so they are all on the same circuit. You may also want to be sure that the AC adapter cables are not not laying or running across other electrical components plugged into a different socket.

If you get the same hum through your headphones check to see if the headphones were manufactured with shielded cabling. A shielded cable is made with a wire mesh around the outside that helps reduce electrical noise. Hope this helps a little. Thanks!

Crackling noise coming from travel power adapter


Only one reason for the noise on a power adaptor and you already guessed it - spark jump. Do not use until repaired or replace.

My acer 5920 wont charge or wont work on ac adaptor but the ac adaptor works fine on my friends laptop


Either the AC port on the back of your laptop has a lose connection - if operation without battery is an issue, or if battery charge only is issue - then battery may have to be reseated or it is at end of life. Test by removing battery and running AC alone. if connection port is bad, laptop will power off immediately/unexpectedly. Good luck! btw - batteries for this unit are around $40 on ebay

Toshiba Satellite M45-S331 willnot operate on


Hello,

You have replaced the battery and then it worked.
Try once with power draining (remove the battery and then press the power button for one minute and then again refix the battery) and check.

Thanks

My Gateway 1450 will not power up. For the last 2 weeks that battery light has been red (battery need recharging). i had the unit turned off with no ac power to it all weekend and not it will not power up....


The motherboard battery is just a little round battery that you can buy at almost any retailer in most pcs. The model number to the battery is usually a CR 2032. This battery does not receive any power from your power supply. Have you noticed your PC loosing time over the last few months? This is usually a good indication that the motherboard battery is dying. The lights that you refer to though should only partain to the rechargable battery of the notebook. During the past two weeks while the red light was on, was the AC adaptor plugged in to the laptop and plugged into an AC source? If your AC adaptor has been plugged in and is not charging the notebook battery then there could be one or both of the following problems: your notebook battery could be bad or your AC adaptor could be bad. Something you may or may not know is that it is not good to keep the AC adaptor plugged in all the time. This causes the notebook battery not to fully discharge after being charged. Over a long period of time, the battery will not even charge anymore. My suggestion is that if you know someone with a similar AC adaptor to yours, borrow it to see if it charges your battery. If the battery doesn't charge then you know to replace. However, I am almost certain that you problem is the battery. Sometime older laptops like the one I have has a reset button on the underside. If yours has one try removing the battery and leave it out. Then plug in the power and press and hold the reset button for 10 to 20 seconds. If no reset button is on yours then do the same process with the battery removed and power adding, but hold the power button instead.

How can a fujifilm A160 be charged up? Just by batteries? Or whilst it's connected to my laptop whilst I download pictures from it? Thank you!


Your A160 can only be powered by the AA batteries or by an AC adapter, such as Fuji's AC-3v or AC-3vx chargers. It won't operate on the power from a USB port. If this answers your question, please rate the answer favorably.

When i go to charge my kodak M863 camera (in the wall or by USB) the green light flashes and then the red light blinks 3 times. please help this is the first time charging my camera.


You can used the USB cable to charged the camera, But some of the M863 camera will not take charged usign the USB cable., I strongy suggest used the AC adaptor just make sure the AC adaptor is 5V ac adaptor it will only charged using the 5V adaptor., About the flashing green it indicates camera is charging just wait for the solid green light it means it fully charged

You may purchased also a special charger for your battery(KLIC-7001)- cahrer model is K8600-C. i think the price of this charger is around $29.00

Battery on lap top is not charging


switch off - disconnect ac adaptor - wait 3 seconds - connect ac adaptor - repeat about 20 times.
Is charge light blinking when you connect ac adaptor?
Try reseating battery.
If battery is old (over 2 years) or heavily used then it may need replacing. They only last for 250-500 complete discharges.

Lap top problem


Hi

If the AC power light is blinking, try the following steps:

1 Cut off power to the computer by disconnecting the AC adaptor and removing the battery. The error condition will be interrupted, and the AC power light will stop flashing.

2 Put the battery back into the computer. Do not connect the AC adaptor. Try turning the computer on again. If the computer starts normally, the AC adaptor may be
defective and will need to be replaced. If the AC power light starts flashing, remove the battery, and continue with the steps below.

3 Connect the AC adaptor to the computer. Leave the battery out of the computer. Try turning the computer on again. If the computer starts normally, the battery may need charging, may be depleted, or may be defective. Turn the computer on, insert the battery, and then leave the computer running for several hours, which will deliver a slow, steady “trickle-charge” to the battery. Once the battery has been trickle-charged, it may begin working correctly again. If the trickle-charging does not prove effective, consider replacing the battery with a new one.

4 Connect the AC adaptor to a different power outlet, preferably in a different room. If the computer starts normally, there may be a problem with the AC outlet itself, or the voltage level available from it.

5 Verify that the AC adaptor is the correct unit for your computer model. The computer may not be able to start from an AC adaptor that is rated for less current (amperage) than the computer requires, even if the rated voltage is correct, and the plug fits correctly in the DC-IN socket. The labels on the bottom of the computer and the AC adaptor show the specifications for voltage ("V") and current ("A") for each device. The voltage level must match exactly. The amperage rating of the AC adaptor must be equal to or greater than that required by the computer
