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.

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

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.

Windows Vista has always had a prob with netgear.

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.

Wi fi light off


Hello Lisa

(01) Is the switch for your WiFi radio in the ON position?

(02) If it is, then it's possible your WiFi connection is (in your operating system) disabled or missing.

(03) If your operating system is Windows Vista, please, go HERE to learn how to access your network connections.

(04) If your operating system is Windows XP
(a) Click on START
(b) Click on NETWORK CONNECTIONS

(05) In either case, make sure your wireless connection is showing there.

(06) If your wireless connection is showing in your network connections, it is likely disabled. In that case, right click on it and choose ENABLE.

(07) Now, let's see if your WiFi LED lights back up for you.

(08) If it doesn't or if there was not a wireless connection in your network connections, please, post back here and let us know. We'll work w/ you to determine why it's missing.

Thank you,
BJ @:)
