Question about Dell Latitude C400 Notebook

Dell C400 will not boot using LCD screen when cold

My Dell C400 has a new HD, two new sticks of ram, a new LCD, new CMOS battery with a refurbished motherboard and palmrest. It will not boot using the LCD screen when it is cold. It always will boot with an external monitor. I've found no settings in the BIOS that repairs this problem. After the laptop has booted using an external montor and warmed up, sometimes it will boot using only the LCD screen. Any clues what might be happening?

I have seen this problem before, after booting to the external monitor go into the display settings and try setting the resolution to 1024 X 768 and the color settng to 16 bit or preferably 32 bit. If you can do this, then shut down the laptop remove the external monitor and try booting on the LCD display. BPCS

Why doesnt my compter get past the booting screen?


Early in the post stage, bad ram or failing hard drive.

Do all the following with the PC unplugged:

Remove cables from Hard drive - pay attention to where the go back, turn on pc and see if it goes further (if it does, you probably have a failing hdd and should seek professional help immediately. Don't keep trying it, else you lose everything for sure.

If that doesn't work, plug the hdd back in and again with power UNPLUGGED, remove one of the ram sticks. Turn pc on.

If works, you have a bad stick or slot, if still nothing, put ram back in and take out next stick. Repeat until you find the problem.

Put the HD in an other computer , start the instal process and let the installation program copy all files to HD. Just when computer is to restart you turn off the computer and put the HD in the C400 and continue the installation from there . When you got one computer going , clone the HD.
Try also to repartion and reformat (hard) the HD.

Won't boot up gets blue screen asking for us to


Usually if you've encounter a blue screen the first cause of this should be the RAM. Check the RAM maybe it is clogged by the dust you need to clean the RAM. If the same things happen you must reset also the CMOS battery and the jamper. The jamper located near the CMOS battery at the south bridge.

In any other circumstances to solve this you need to install a fresh copy of windows. Some causes of blue screen is the corrupted software that need a full copy.

Dell 4400 won't power up Flea light works


For non-BIOS issues:

If you did not try to update BIOS before the problem started then try these troubleshooting steps.

1. Full power down. Unplug the power cord from the Power supply. Then hold down the pc power button (this discharges any residual power in the capacitors).

2. Open the case and reseat the graphics card, hard drive, and RAM.

3. Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

4. Set the Cmos jumper to clear. Power up the pc. Power down the PC. Set the Cmos jumper back to normal position, power up the PC.

5. Unplug and replug all the power supply cables.

6. Check the powersupply function. Either by a powersupply voltage checker (20-25 dollars at local PC shop), get the supply tested at a PC shop (usually a free service), put the powersupply in a different pc, or try a different powersupply in the problem computer.

If the Powersupply checks out ok, then you will have to do a process of elimination to find out what part or parts are the culprit of the No-Boot.

Start by pulling all the ram sticks if you have not already. This is the easiest components to check and usually a culprit.

Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

If it is not the RAM, you have to continue removing items such as sound cards, un-plugging hard drives and optical drives, other PCI cards. Do this one at a time until you find the culprit. If a POST screen, meaning you can see Anything from the PC brand name to Motherboard brand name appearing on the screen. The PC may not boot to windows, but it Does post at this point, and with that the problem is resolved. If windows does not load, then you have a new problem. Best dealt with asking a new question.

Good luck!

Computer won't boot up after attempting to install new memory


I believe resetting the CMOS would fix this problem. To reset the CMOS, open up the computer and locate a battery similar to this one (it's on the motherboard):

Picture

Once you find it, pull it out. Leave it out for about 24 hours (one day) afterward placing the battery back into its slot on the motherboard. Now try booting up.

It should now successfully start up requesting that you make changes to the BIOS since the CMOS was just reset. Afterward you should be able to use the computer normally.

NOTE: Try resetting the CMOS with the original RAM inside the computer. The new RAM might be forcing the motherboard to send too much voltage or use an incompatible Mhz setting to support the new stick of RAM.

Let me know how it turns out and if I can do anything else to assist you.

Dell latitude C400 will not boot from hard drive.


Hi, This sounds like a dead hard drive. Still, you may want to try: 1. Enter your CMOS/BIOS and verify that your laptop can detect the hard drive. Further check if it is configured to boot first from the HD; 2. Slip in your XP or Recovery CD and boot from that. It may be that the boot section/files of your HD got messed up. When prompted, instruct the CD to repair; 3. Remove your laptop's HD and connect it to a 2nd PC as an external/removable drive using a 2.5 enclusore with USB attachment. Thereafter proceed to diagnose, check and hopefully recover your important files; 4. If confirmed of a defective HD, replace and reinstall your OS. Hope this be of some help/idea. Post back how things turned up or should you need further information. Good luck and kind regards.
