Re: it wont power up.
Generally, a portable that doesn't do anything has a power problem, the trick is determining which component is at fault.
The first step is checking the power source, which for a portable is an AC adapter. Both the system and the battery are supplied power from the adapter, so if power is not getting from the adapter to the system, then eventually you end up in a no power state. If you have a known good AC adapter available, that is the fastest test. The adapter from any D-Series Dell will work on a 505. If D-Series Dell portable is available you can also test your AC Adapter and Battery in that system. If they work in that system, then next is a motherboard replacement in the 505.
If a known good adapter is not available, then check out the DC outputof the adapter barrel connector. The inside of the barrel (Not the small wire) is the positive contact, the outside is the negative. A multimeter set for DC current should read about 19 volts output from the adapter.
If the AC adapter checkout, try booting the system WITHOUT the battery. A failing battery can cause a no power situation.
If the Battery and AC adapter are good, then the last item in the troubleshooting line is the motherboard. If the system is under warranty, you contact Dell for repairs. If not, then you can replace the motherboard yourself if you are handy with tools for less than $200.

Im very sorry to hear that, please follow these simple steps for you to be able to isolate the exact problem.
1. Removed the battery.
2. Connect the laptop directly to the power outlet without using the battery just for the meantime.
3. Turn on the laptop. If the laptop is able to power on, that means that the AC adapter is working fine as well as the DC port. If the laptop is not able to turn on, it maybe the AC adapter itself or the DC port.
4. Try to use another AC adapter if possible, make sure that that AC adapter is working fine. If the laptop is still not turning on, the problem is with the DC port itself. In that case, you will need to replaced the Motherboard itself.
Hope this will help...Thank you for using Fixya...
Does the power light comes on? Try a power drain. Disconnect the adapter, remove the battery, press and hold down the power button for 10 seconds. Put the battery back and the adapter and try to turn it on. Still no display? Take it to an Acer repair center.
Hi. I would suggest you double check the ac adapter if the powercord is properly attach to it ot also you might want to try powerdraining or powercycling your computer. To do this you must turn off your laptop then remove the battery and unplug the ac adapter then press and hold the power button for 20 seconds while the battery and ac adapter is out, after that place back the battery and plugin the ac adapter and try turning on your laptop, if this doesnt work then try power draining it again and just use the ac adapter or just plug it in without the battery then try again turning it on. If it still has the power issue then try a known good ac adapter so that you could double check that it is not an ac adapter issue or a battery issue. If all that trouble shooting step doesnt work then you could also try calling acer tech support to help you on your issue if your machine or laptop is still under warranty they would help you fix it by sending that laptop to there depot without any charge. Hope this Helps
Verify that you obtained an exact replacement power adapter for the Dell. If it is an exact replacement then try this. Disconnect power adapter. Remove battery. Reconnect power adapter without the battery. If it turns on, then power off and place battery back in. Then try again. If problem returns, there could be a problem with the battery itself.
Unplug All External Devices Unplug the AC Adapter From the Wall Outlet. Disconnect the AC Adapter From the Laptop Reseated the power cable to the adapter. Remove the Battery Connect the AC Adapter Directly to a Known Good Outlet, But Not to the Computer Verify That the AC Power Adapter Has a Solid Green or Blue Light. The AC adapter status light is solid green. The AC adapter status light is solid green.Press the Power Button and Check for POST. Post means if you see the dell logo,remove the battery, plug the ac if still it wont turn on or doesnt have any light,Reseat the Memory if after reseatting the memory still the same problem it might be a bad motherboard.
