Purchasing dell inspiron 2200 ac adapter tips
During the last week, it seems the AC adapter for my dell Laptop that I purchased one year ago has developed a fault meaning that the AC adapter is not detected by the laptop. It still charges and powers the laptop fine however on every boot it makes a very loud beep and requires you to strike F1 to ignore the warning. In addition, the performance of the laptop is reduced to a minimun acer TravelMate 280 battery，acer TravelMate 290 battery.
After looking around, it seems the AC adaptor contains a proprietary 1-wire device that transmits a serial number to the laptop. However, the chip and communications are very prone to breakage, which is what seems to have happened in my case. This is not an isolated incident.
Unfortunately, the ac adapter is not in the warranty time, so I need to buy a new one. But I was confused that which is the right hp ac adapter after I searched the item via internet. There are so many dell inspiron 2200 ac adapter in the searching results and each one has a different price. Which one is the right one for me? So hard for me to choose acer TravelMate 3000 battery，acer TravelMate 4000 battery!
Luckily, one of my friend is helped me, for he works in a computer shop and has the knowledge of how to choose a right laptop ac adapter for the notebooks. In fact, it is very easy to choose a right one. Just check two aspects before you buy the item:
1. Specifications: If you plan to buy after-market, choose an AC adapter with the same electronic specifications as your old one. Make sure its plug size is compatible with the device you plan to use it with. To be sure, bring your device with you before you buy.
2. Volts and milliamps: When replacing your old AC adapter, look for one that matches the volts and milliamps of your old one. This information should be printed on the original adapter acer TravelMate 4050 battery，acer TravelMate 4060 battery.
