I need a power adapter for telephone base for model 30524


Not a problem. Take the base unit with you to Radio Shack and they will get you a proper replacement. (The numbers on the plug in to the unit will say how many volts Direct Current are required to operate is properly and the tag underneath will also state how many milliWatts of power are required at that voltage.) The key is buying the proper plug in end that fits the socket. Radio Shack has units with several socket tips so you may select the proper one. Make sure the polarity of the socket plug you use matches the wire polarity... the stripe on one side of the power cord is the + side on the socket tip.

As long as you buy a genuine Dell AC adapter, it will be find.
Do not buy a 3rd party AC adapter.

I have bought at least a dozen Dell AC adapters on eBay. Just make sure the photo shows a genuine Dell.

Either you can buy the original battery from Black and Decker or you can replace with the same mA rating with the regular types available in all stores any rechargebale variety with a good mA rating.
Couple in series and parallel to get the desired voltage and current rating.

Yamaha psr-280 flashing display no key response or sound. Is it dead??


Your adapter should be a 12 volt DC delivering 2 amps (2000 ma). If the adapter is too small, you will have the symptoms you are seeing. Make sure the polarity is correct. DO NOT use the so called "universal adapters".

I have a very old Maxtor external 200 GB hard drive. I can not find the power adapter for it. On the label, a part of it rads 12V 2A - does that's mean I need to look for a 12 volt, 2 amp power adapter?


Depending on the power adapter, you might be able to pickup one at Radio Shack..
If it is a single pin plug, check near the power adapter jack to see if it shows you polarity of the
center pin, which will either be "+" or "-" Take this information to your local Radio Shack along
with the voltage and amperage requirements
