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).

SATA 2.5 connectors different than current Presario R4000 laptop

It seems that your notebook does not have sata connection to Hard drive. Your harddrive is IDE connection. Sorry but you can't use SATA on this laptop.

Laptop screen does not come on after last reboot. sounds indicate that the laptop rebooted though

Possibke tha the video driver got trashed when it was shut down.

If this is running Windows, have you tried safe mode? That loads 640 X 480 poixels - or 800 X 768.
Press the F5 key repeatedly when you see the splash screen and choose safe mode.
You may also hook up an external monitor to see if it's a bad display.

Solution for "my laptoop seems to want to boot but when is is done booting the screen turns black and remains that"

If the laptop appears to boot up and you can't see an image on the screen, you need to determine if the screen is faulty or the video card.
Connect an external monitor to the laptop's external video port, power up the monitor first and then boot up the laprop. If you get a normal video image on the monitor then the video card is OK and the fault is with the LCD screen.
If you don't get an image or POST information, then the LCD screen could be faulty or the laptop didn't boot up.
Please get back to me with the results of your tests and any error messages etc. so I can advise further.

Compaq Presario R4000 looses video and freezes after a while

The problem you describe can be caused by two different things. The two are not related to each other in any way.

The first, which is more common on desktop computers than laptop computers, is a thermal problem. The video chipset is overheating and causing a shutdown of the video. It is possible that this overheating is actually the cpu, but I don't think so, based on your description.

The second is the video power inverter chip. The power needed to keep the lcd screen lit up on a laptop is considerably more than what is needed to run the laptop itself. For this reason, a small power inverter chip is installed on laptops. It is usually found under the plastic bezal that surrounds the screen, and usually on the bottom. When this chip goes bad, the symptoms are as you have described.

Here's a couple things you can do before seeing a technician or teaching yourself to take apart your laptop. Plug in a different monitor; an external monitor and restart your computer. You should have a function option that will let you see two monitors at once. (that's the fn key, usually in the lower left of your keyboard). With two monitors showing exactly the same pictures, see if you can recreate your symptom.

If the problem is in the power inverter chip, the external monitor should remain on when the lcd monitor goes black.

If the problem is inside your computer (video or cpu overheating) then both monitors will go off.

good luck

There is no driver from Compaq because it just uses a standard driver from the operating system.

Try removing the keyboard from the device manager.

Then restarting the computer.

Let me know what happens.
