My dell inspiron 6400 won't start, red light then green light flashes ansd nothing happens, try to take out the battery and putting it back, no results, help


The following troubleshooting guidelines are basic troubleshooting steps. Battery Charging It is recommended to charge the battery while the system is off for faster charge times. Users may notice longer charge times when the system is powered on and running graphics extensive applications.
No POST If the system does not perform a Power On Self Test, there are various things to look for:
  1. Check to ensure that the system has a power light.
  2. If the system has no power light, ensure that it is plugged into AC power. Remove the battery.
  3. If the system has power but is not performing a POST, check to see if the keyboard status lights flash to indicate a successful POST, but no video, or that the keyboard status lights are lit in a sequence indicating a system problem.

  1. With the power off and the system unplugged, remove all CRUs from the system and reconnect that AC adapter to the system and try again.
  2. Run the On Board Diagnostics (OBD).
Video If the LCD on the system shows no display, or has other LCD problems, there are some basic steps to take:
  1. If the LCD is not displaying video or the video is garbled, run the BIST Test.
  2. If the LCD is not displaying any video, connect an external monitor to eliminate a no POST problem. A good image on the external monitor eliminates a video card problem or a POST problem.
  3. Connect an external monitor when possible for all LCD related problems, to help eliminate a software possibility or video card problem.
  4. If the LCD has extremely dim video, attempt to adjust the brightness or connect an AC adapter to eliminate a power management conservation setting set in the BIOS.
  5. If the LCD has lines on the screen, check the system during POST as well as system setup to verify if the lines are present in all modes of operation. Run the BIST Utility.
  6. If the LCD has color problems, run the BIST Utility.
  7. Run the On Board Diagnostics (OBD).

I have a Dell laptop D505. The laptop powers up but the screen display is very dim. I can't see the image on the monitor. I've tried to manually increase the color/brightness button and nothing changes. ...


Sounds like your inverter or your backlight is failing. The inverter is an easy repair, the backlight can be replaced but it involves taking the LCD panel apart, The backlight comes installed on new screens. I can include a service manual below and possibly a generic guide to backlight replacement....

New battery and still won't charge.


first, check that the battery connection isn't blocked by a sticker or something.
second: try disconnecting the battery and ac and hold the power button for 1 minute. then give the battery and ac another try.

let us know how it goes.

if it still doesn't work, time for a warranty replacement.

Dell C640 powers off when lcd is plugged in


There is a possibility that the socket for the lcd ribbon has shorted somewhere, either the socket itself, or the tracks on the motherboard leading to the power supply circuit or video card. If this happens then there is no DIY fix, unless you have PCB cutting equipment or a micro trace pencil. If you are desperate, you can also look into replacing the LCD's power inverter chip. They only cost about $30-40 and may fix the issue if it is blown and trying to pull way too much current.
