Question about Computers & Internet

1 Answer

I have a dell Inspiron 9400 laptop. When I go to turn it on, all I get is a black screen and it switches off. The 9 lock stays on, the A lock and arrow lock flashes. I am being told by a friend that it is a hardware failure. The battery indicator light shows that the battery is charged but I know the battery isn't fully charged.

Your battery HAS to stay in if its not working which means the OS needs the extra power.

Dell Inspiron 9400 laptop display problem


First power the system on using Fn+Power and see if the diags run and you have video. If you have video in the diagnostics, then I'd suspect the video card as the failure point.
Also connect an external monitor and press Fn + F8 to activate the VGA port If you get video on an external monitor, I'd suspect the LCD as the failure point.

I have a dell Inspirion 9400 and it won't start. When I press the power button, all that happens is the power light and the dvd player light comes on and about 3 seconds it turns off. Does it with and...


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.

it was a brilliant laptop ever manufactured. check the costing. for the new laptop as well as the warranty pricing. Yes it is worth repairing, if you can manage the cost. becasue extending warranties would be a cheaper option. The LCD needs to be repalced in your case.
