I have replaced my dell inspiron 6400 screen cover. Now my wifi connection does not work. I am getting a message "no wifi networks found". Manual diagnostics tool shows "scan test"...

1st : check if the wireless capability of your notebook is enabled. There might be a switch or button that needs to be pressed to enable the wireless capabilty of your notebook.

2nd : check the device manager if the wireless network card is listed with no question mark or exclamation point. if it has, then reinstall the driver.

3nd or the wireless card might loosen.. at the bottom of your notebook, you will find several screws there. look for a small box usually with 2 screws. Open that up and you should see a black and white cable connected to a small card. Ensure those 2 cables are connected. Ensure that the laptop is powered off when you do this. Then try it again.

Hope that works.

Dell inspiron 6400 start up problem.

Can you hear the hard drive spinning and the computer appears to be running but you you get a blank screen. If you look at the LCD screen at an acute angle and you see a dim image. then you have a backlight problem. To determine if you have a video card problem or a lcd screen problem, Connect an external monitor to your laptop and power the monitor up first and then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
Get back to me with the results of these tests and any error messages etc. so I can advise you.

DELL inspiron 6400 not switched on

This is a no boot issue. Youre saying that you can perfectly run the PSA diagnostics but doesnt load Windows rather it stays on black screen, meaning the boot loader of Windows failed to load. You need to reinstall windows on your computer

DELL inspiron 6400 laptop screen turned black

this sounds like a classic case of inverter problems, it could be just inverter coil thats gone which is an inexpensive repair, if it is the inverter then its a bit more.
try the Fn the F key that shows two tv screen icons, it may just have switched to external mode by accident

good luck
