Question about Dell Inspiron 9400 Notebook

1 Answer

I have a Dell Inspiron 9400- used. I do not know what has/may have or haven't happened to it unfortunately:( When I turn on the computer with power button, computer clearly turns on, then the DELL startup page is displayed BRIEFLY (like for a split second only!), then the screen goes blank/black and stays that way. What can I do? If anything. Thanks

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.

Have a Dell Inspiron 9400, when running off the battery the LCD is perfect, as soon as I plug into power the screen goes black. Ive tried multiple power supplies and still the same result?????


you may need to change your power settings. it sounds like when you plug it in it goes into a mode thinking there is another monitor hold the FN key and press a key usually f5 that looks like a computer monitory. anyway plug in the pwoer cable, and hold fn and press the key that looks like a computer monitor maybe twice until the monitor comes back on let me know if that works!

Dell 9400 wont show AC power icon


If the computer is connected to an electrical outlet, the about10.jpg light operates as follows:
  • Solid green: The battery is charging.

  • Flashing green: The battery is almost fully charged.

If the computer is running on a battery, the about41.jpg light operates as follows:
  • Off: The battery is adequately charged (or the computer is turned off).

  • Flashing orange: The battery charge is low.

  • Solid orange: The battery charge is critically low.
Looks like the AC adaptor is faulty.
