Re: Gateway 405ROG AC Adapter Output Polarity
It doesn't matter if its + or - , make sure the pc runs on 19 volts and that the AC adapter does also, look underneath the laptop to find out if it does run on 19 volts but make sure the power jack fits the socket o the laptop before plugging it in to the mains

For Any Adapter:
As long as the Voltage and Power output of the power supply (wall outlet or other) matches the input requirements for the adapter whether 110V or 220V.at enough amp output; and
IFF the dc output of the adapter is exactly the same voltage and has for amps at a minimum matches the maximum amperage requirement for the input of the device, any of them will work, as long as it has the right connector with the correct polarity needed for the device!
Or, in other words...
Supply Output V = Adapter Input V
Adapter Output V = Device V
Adapter Output A(min) >= Device A(max)
The computer doesn't need any drivers to recognize an AC Adapter. If you have purchased the correct AC Adapter for your laptop then it should just work when you plug it in. If it does not then my guess is either you have received a faulty AC Adapter or the DC Jack which you plug into in the back of the laptop is bad. I am assuming your battery is dead and when you plug it in and turn it on nothing happens? You can also try taking the battery out and try to power it on with the AC Adapter plugged in.
The Dell Latitude D610 takes a PA-10 or PA12 AC Adapter. It's 65W or 90W
For 90 watt Adapter the output voltage on your AC Adapter label should read 19.5V and 4.62A At least that's what the Dell brand reads so it should be close to that.
i would try purchasing a universal laptop charger on ebay and see if it works. they are under 25 bux. worse case scenario you will have a backup ac adapter. be careful plugging in other ac adapters because the polarity could be wrong or it could have to much amps
This normally is an indication that the AC adapter is not powering the system and the remaining residual power in the battery only powers the system momentarily. Things to try:
If available, try a different AC adapter. If no known good adapter is available, then use a multimeter to see if 19 VDC is available in the DC connector. If system powers up on a different adapter, or the Adapter has no power at the DC connection, replace the adapter.
Remove all drives, Memory, battery, and wireless cards, and see if the system powers on. If it does, add 1 RAM module, and see if the system boots. If it does, add other components back one at a time until you ID the failure. If system doesn't change, then replace the motherboard.
Look on the charger itself & it will have the correct output voltage & polarity stamped on the charger. Then get a volt meter to verify if the correct output voltage is present. If the volt meter reads less than what is stamped on the charger, then I would recommend replacing the charger at that point.
