    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

I have an Asus Eee and would like to use my Kensington Universal car/air adapter to power it. As far as the voltage is concerned, there is no problem as the laptop runs on 19V which there is a fitting...


Thank you for using FixYa

The physical connection is one thing. If it looks the same it may work, however you might want to know the amps as well, and if the tip is positive or negative. As an alternative the USB adapter may be easier fix and even WalMart has one that fits in the cigarette lighter. My Asus is 19v. 2.1amp, with a tip +.


I hope this was useful and please comment if this was helpful to you.

Replacement tips for Kensington 120W AC/DC adapter model 33197


I have the same model adapter for my dell, I believe there is a number on the tip that you need, have you tried ebay for the part they are called 'smart tips'. I think it's a different adapter direct from kensington now, but you can buy them from 3rd parties.

Save yourself a lot of time and grief by going to Radio Shack and getting a connector adapter. They have an "octopus" that will match what you need and then just be careful to observe polarity when you attach it. Steve Medley

I have a 90w ac/dc power adapter w/usb K33403. It has worked fine and someone tripped over the cord and the power adapter now makes a beeping sound whether it is plugged into the computer or not.
