    I have the same problem, but I noticed when plug out the power cord from thebrick which links to laptop, it stopped beeping. So maybe the power cord is broken?

I have the same model. I pinched the cord from the from the supply to the notebook. The cord looked ok from the outside, but was damaged internally. I called Kensington support and they sent out a referb unit at no cost using only the serial number to validate the date of manufacture. The company has a two year replacement policy from purchase date, but if you lose your receipt they came go by maufacture date. give them a call.

    I had this problem with a Kensington power adapter and the problem resolved itself by simply untangling the leads.
    The DC output from the power block was all tied up in knots with the mains lead, so I assume excessive EM interference from the mains lead was causing excessive noise on the clean DC output, so the beeping while the DC output shuts-down must surely be to protect our output from a potentially hazardous noisy/transitory DC power supply.

Kensington power outlset beeping


the fit on the end of the battery adapter basically shorts and back fires and holds electricity in the battery making it unable to connect at the wall and flow again .... so you have to be able to Release the bent up or saved electricity the battery retained... by either plugging it in at the same time your finger can turn your computer on generating an instant flow.. this is very touchy area...but this morning after many times of doing it this above way i simply plugged my new iphone into the usb side socket to create a flow ( i have nothing that fits the adapters) and with the first plug from phone to usb port WALA xox I've been doing this off and on for 2 years since i first purchased it but it has never ever charged my battery ~ it's junk product but nothing else was available to purchase

Advent k200 laptop does not charge new battery


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...Your response is very much appreciated...

Hum from dell laptop power adaptor when using a sound system


Hi,
as i understand you are facing this hum on all the three AC adapters,
there could be any of the following reasons for that
1) If the laptops were bought within the same period and all the AC adapters came from the same faulty lot

2) Or the AC adapters are made in this way so they produce this hum always

Try calling their Tech support helpline for Dell and see if a replacement can help you or if the AC adapters have a design fault of producing hum is their a solution that they have for it

If you Think my solution was of any help please do rate me

No power


HI,
you haven't mentioned clearly is the laptop in on state or are the batteries able to give power to laptop to start

try this solution if you have checked that the Ac Adapter is finr

take out the battery from the laptop and then plugin the AC adapter and then try to start your laptop

if your laptop starts without the battery by getting power through the Ac adapter, most likely your battery is Bad, get it replaced, if it doesn't start then it can be power circuit on the motherboard or the connectors you should get it checked from a technician.

If you think my solution was helpfull please do rate me

DELL XPS M140 POWER ISSUE


Hi brendanram!

I am claudus_07 and i was a Dell - XPS Technical Support Specialist before so i will be glad to assist you with your concern.

As you said into your post, you tried plugging the AC Adapter to the power source without plugging the other end into the XPS laptop and the Green Light on the adapter is lit. But when you plug the jack on the laptop, the Green light is out. As for my experience on your laptop, there could be a problem with the power supply or the motherboard of your XPS laptop. Because everytime you plug the adapter to the laptop, the green light is going out so it means that the laptop or the adapter is grounded.

Here's what you need you to:

Step 1: Call Dell XPS Technical Support 1-800-624-9896
Step 2: Tell them the issue and the things that youve done.
Step 3: At the end of the troubleshooting, i know that the Technician will either replace the Power Supply, Motherboard, or the Adapter. (if you have a friend that has a Adapter same as yours, you may try to use it just to isolate the issue the Technician will choose from the Power Supply or the motherboard)
Step 4: If the Technician replaces the power supply and the issue still persists, call technical support again and ask them to replace the motherboard, no need to repeat the troubleshooting steps anymore just tell them that youre already done with it. (Dont ask for a system exchange, because i know that they will not give what you want.)

--------------------------------------------------------------------------------------------
Thanks!
I know it will work. Be Positive!
Your good rating will be very much appreciated.

Good luck and thank you!
