Charging light is flashing


There are two possible causes for this issue:
1) Your dell 9400 charger is malfunction
2) Your laptop dc power jack is loose or dead

Possible troubleshooting step:
1) Borrow a compatible dell charger to plug in your laptop, if it works without any issue, it means your dell inspiron 9400 adapter need to be replaced.

2) If the compatible dell 9400 charger won't work normally, the problem may lie in your dc power jack.

Hope this will help.

Dell inspiron 9400 not booting up. no light in display. num keys and caps locks flashing


Hello.

The most common reasons are the battery, power jack and power adapter/cord.

Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

Hello.

Return your power adapter to Walmart and replace. I'd suggest taking the laptop with you to further test in the store with the adapter you buy. Be certain that the new power adapter is compatible with the specific Dell Inspiron notebook series that you own.

Hope this helps.

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.

Dell Inspiron 9400 will not charge - AC adaptor not recognised


Does the laptop power up just no charge the battery? If the laptop does not power on then you may have a bad power supply in the unit. If it does power up than you most likely have a bad battery connector of blown fuse on the motherboard. The flashing of the BIOS is done with a bootable cd or floppy but this will not keep the new battery from charging. The reason Dell states that you need at least 10% battery to flash a BIOS is because if your AC power goes out while you are doing a BIOS upgrade and you don't have battery power the BIOS will be incomplete and your laptop will not boot again without replacing the motherboard.
