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

When i turn on my Dell Inspiron 2400 Desktop Computer why won`t it start.


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?

My laptop won't turn on. I tried taking out the battery, a different battery, a differnet power cord. It won't turn on. Is there a way to reset it?


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.

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.
