Yes it will (or should ) work without a battery, just make sure you don't unplug the connector while you are working with your computer or you will loose your work w/ no warning, laptop power cords become detached easily so be careful!

Probably the AC Adapter is no good....Go to e-bay and purchase a new AC Adapter for that model # notebook. But if it shows charging then try first by taking out the battery and see if the AC adapter will run the computer without the battery in it (if so, then the adapter is good, the battery is actually bad, so replace the battery instead).
Hello, There are three parts in the computer that you need to check. 1. Ac Adapter - it could be defective. 2. Battery - it could be that the battery and ac adapter won't work together because the battery has gone bad. We cannot tell without checking that. 3. Motherboard - it could be that the motherboard's power port is defective. Do the following so that you can isolate the problem. 1. Remove the battery and use the Ac Adapter only and turn on your computer. If it turns on without any problem, then replace your battery. 2. If the computer still reboots with the ac adapter plugged in (no battery), then replace the ac adapter. or try using a different ac adapter which is compatible with your computer and check if it produces the same problem. If the other adapter produces the same problem, then it's in your motherboard and you need to get it fixed by a technician.
If the laptop is still working when it is plugged in , then the ac adapter is good and the battery is just bad. If the laptop will not work when it is plugged in then more than likely the ac adapter is bad.
You either have a faulty ac adapter; a bad power supply in your laptop; a bad battery; or a blown LED indicator light.
1. If the connection is not loose when you plug in your ac adapter try letting the laptop charge for a while. (If you are using the correct ac adapter)
2. Try removing your battery and using the ac adapter. If this works the battery is bad.
3. Try a new ac adapter.
4. Power supply is bad
If it will not work on AC Adapter without battery in it, then you have a bad AC Adapter and the battery is fine. You don't have to get an expensive AC adapter from the original manufacturer. Just look on the bottom of the AC adapter and write down the Volts and Wattage. You can get another at a place like Lowe's or Home Depot. But you must make sure that the Voltage matches exactly, to much voltage and it will fry your computer, to little voltage and it will not run your computer.
Dell uses a proprietary SMBus protocol over the center pin to communicate the type and power capability of the attached adapter. The laptop uses this information to determine if it can charge the battery without browning out the motherboard. If you use a knock-off power supply that doesn't communicate properly (or at all) over SMBus, then the computer will complain and won't charge the battery. Sorry, Dell has us all right where they want us. Find a used actual Dell adapter on eBay for $20 if you can.
If the ac adapter was plugged into the laptop at the time may be bad news. Unplug AC adapter, take out the battery and hold power button for 10 seconds. Then connect AC adapter and hit power. If that doesn't work put battery back in without ac adapter and hit power button.
If neither test works bring to repair center for diagnosis. Best case AC adapter would need replacing. Worst case Motherboard fried.
