Where i can find dell ----1100 inspiron ac adapter???

unplug, take out battery then hold power button for 30 seconds then plug back in and turn on
if the3 laptap gos on without the battery you need a new battery

What kind of problem do you have with this unit? You can't reset AC power adapters for laptops. If it doesn't charge the battery or turn the unit on, it would be one of two possible problems, usually. The adapter is bad or the plug socket is broken on the inside, either from age or getting bumped while plugged in.(most common problem). The only thing you can do in that case is to have the socket replaced. (the entire notebook has to be disassembled to replace and put back together) I'm sorry to say but, Most computer shops won't do that. Check the adapter first, is the green light on? Check with a voltmeter to verify. Hope this helps but sorry for giving bad news.

Read the same topic "dell ac adapter can not be determined" on Dell.com and getsatisfaction.com. May it will help.
"The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 90W AC adapter or higher for best system operation"
AC power adapter can not be determind

Dell Inspiron 6400 AC Adapter

Adapter should be faulty,kindly check with one another.

if again you are facing the problem might be short circuits in the motherboard

the Dell AC adapter has a sensing pin so the bios can determine the wattage of the adapter. If the system cannot ID the adapter, the battery charger circuit is disabled. You'll need a functional DELL ac adapter to get the battery to charge

On the long term, a power adapter with a bigger amperage can damage battery and battery charger.

Better to get an adapter with same specs as the 65/70W one , or an original replacemant:

You will need to purchace a , PCMCIA wireless adapter.

take another adapter , same type you have it and prove is working or not?
if yes meaning that output current in your adapter is wrong it is defektive , and change, if even second adapter is making same thing try to get another model adpter that is close in power and curent ratin with yours or same, if isnt working this too try another batery because maybe is finished, if even new batery dont work with your adapter or a second adapter you have to service your laptop inside in electric circuit entering is blown out.

check your battery. may be it it faulty.
or check also your adpter power supply and earthing working properly.

The AC adapter has a small wire in the center of the connector to the system. This sensing wire, if bent or broken will cause the error you mention.

Check the inside of the connector, since it is new, you can call Dell 800-624-9896 for a replacement adapter.
