I have a Tell Inspirion 9400 and it won't start. When I press the power button, all that happens is the power light and the light next to it come on and about 3 seconds later it makes a sad noise and turns off. Does it with and without the battery and/or power adapter, tried all combinations.

Is the computer plugged in to a known good power source with a known good power cord? Also, make sure the power is fully seated on both ends. When you press the power button are you getting any indicator lights? The power button itself has an LED that will be either solid green, blinking green, solid amber, blinking amber, or off. Do you hear any beeps?
Are there any lights or indications on the battery itself that might tell you if the battery is good? I had a laptop with a similar problem and it turned out to be both a bad battery and a bad "power brick". replacing both fixed my issues. Also, try holding the power cable at the point where it connects to the laptop and push to the left or right. A friend's laptop would only start if you held the power cable to the left. Otherwise, it sounds like a mother board issue. Sorry.
Click start then type Device Manager in the little window. Go to networks adapters click the square or triangle beside it. Right click on the one that says wireless whithin the description and then click ENABLE if this does not work your wifi card is bad. You can purchase an aftermarket really cheap
I have several of these and most often there power supplies blow. since they come by default with only one powser supply. the system won't start
I would start there as most other problems will generate beeps.
try to remove the power cable on that product and then hold the power button for 8 secs. Reinsert back the power cable and press the power button. If it won't turn on, then the power supply is the main cause of trouble. Contact dell right away for repair...
It shows no power on your laptop but it shows you the dvd player led comes on then off. I would suggest try the following:
1. Remove laptop battery, optical drive, hard drive and ram. Remove external peripherals as well.2. Make sure AC Adapter is not yet connected to the laptop. Press and hold on the laptop's power button for 10 seconds to drain the power flea.3. Connect the AC Adapter to a known good power outlet, check AC Adapter power LED if it is on. Try to sense if AC Adapter is not making a bit of noise when it is plugin to the wall power outlet.4. Connect now the AC Adapter to the laptop. Check if AC Adapter LED stays on when it is connected to the laptop. If the LED stays on means the AC Adapter is fine. If the AC Adapter LED turned off check the AC Adapter pin that goes to the laptop AC socket if it is loose.5. If AC Adapter stays on after connecting to the laptop try to power on laptop. If no power LED comes on then this is motherboard problem. 6. Before replacing the motherboard there is one checking needs to do. If you can open your laptop bottom part then good, do this when laptop is not connected to any power source. Try to reseat the laptop CMOS battery then try to power on laptop after, if still fails then replace motherboard. I hope this helps.
(before you do anything remove the battery and th ac plug)remove the memory inside small door on the backside that has a "M" on it now once you remove the memory install the battery, power on if you hear a couple of beep tones you are half way there the motherboard is good so the problem is what you took out so there are two memory slot try them in the A slot one at a time.If the problem is memory replace it.
sounds like bad motherboard/power supply. Just to be sure though have you upgraded the ram? If you have more then one memory chip try siwtching out each one and seeing if it's boot farther. It's possible a dimm went bad or the port it's in went bad. Otherwise motherboard/powersupply
