Question about Dell Inspiron 6400 Notebook

Flashing red and green battery light dell 6400

I tend to belive theres more to it than that. Our lights have been flashing now for over 12 months and we have done nothing to fix it, Manual says overheating but most suffering with this problem will tell you lights start flashing as soon as computer is turned on so it seems no overheating (unless instantaneous) Our L-ion 9 battery still charges to 99%. Tks to all pros and semi pros for their help- Dummy

    We eventually solved the problem (we believe) by visiting Dell.com, locating site for the inspiron 6400 and downloaded an updated (2007?) BIOS that was shown. Blinking red and green stopped shortly afterwards and hasnt returned. It gets quite warm under the inspiron 6400 so we now set ours on a cake cooler when in use.

    I have a flashing battery red light and if i press FN-F3 to inform me about the battery life it said the system can not communicate with the battery. And if I unplug the notebook from AC it turns off. I remove the battery and place it again but nothing happened. Anyone can help me with this?? Do I have to buy a new battery now??

Ok, probably not the battery. With Dell machines, once they overheat to a significant level, it locks an overheating code into the bios, so you will have the light codes at start up. I've had three C840 machines with an overheating issue come through my shop. In order to get the machine working again, you will have to fix the problem that caused the overheating, then there is a download at Dell's site to clear the code. If the initial problem isn't fixed the code won't clear. On the machines that I worked on, 1- had a hair wound in the fan and the other 2 had bad fans one burned up the processor. I believe the 6400 and the C840 is basically the same machine. It's been a while since I worked on those machines so I can't remember exactly where the clearing download is at Dell's site, I do remember reading several forums at Dell on the subject. I hope this approach helps a little more than my last. If you have any more questions please ask.

Can you upgrade cpu in dell 15 i5559-4682slv to i7 ?


It is almost impossible to upgrade proprietary makes like Dell and HP. The are big enough to have motherboards made for them manufactured on price point. This means that they are not built with upgrade in mind. Also the cases are made to fit their motherboard and theirs only.

Go to a computer builder and get a good case, buy a good quality motherboard and equip it with what you can afford. In two years you can upgrade as processors have moved on. Two years after that, you can swap out the motherboard, processor and memory.

How to enable bluetooth


Your computer has to have a bluetooth radio. You can check
Control Panel > System and Security > Device Manager
Do you see a Bluetooth Radio listed?

If not, you don't have BlueTooth on your computer so you will have to add a BlueTooth device by plugging one into a USB port.

If you have a BlueTooth radio, go to Control Panel > Hardware and Sound > Device and Printers > Add a Bluetooth Device

This option is used to connect a blue tooth device (e.g. bluetooth headphons) to your laptop through your bluetooth radio.

See this Windows web page for more information.
Set up Bluetooth enabled device

I will respond to any additional questions you have.

How can i download falsh player on to 2011 imac desk top threw Linux ubentu browser ?


Ok, there are a number of issues with you spelling so I am going to assume you meant the Ubuntu OS. If that is the case the Flash Player install is done by the following:

If you are using the more modern versions of Ubuntu, simply install the Adobe Flash application from Ubuntu Software Centre.

If you are using a version that does not support the Software Centre, try:

Go to the Adobe website.
  • Click on "Download the Latest Player," and choose ".deb for Ubuntu" from the drop down list.
  • Choose "Save File" from the pop up window.
  • Open a terminal window.
    The terminal window will be found under Applications -> Utilities.
  • Change to the directory where your downloaded file was saved.
    cd Download
  • Install the libcurl3 library: sudo apt-get install libcurl3
  • Install the Flash Player: sudo dpkg --install install_flash_player_<version>_linux.deb
    Replace <version> with the latest version number.
  • Restart Firefox.
  • Check that Flash Player was installed.

    hey roger,

    You will need to check your outgoing smtp settings in yahoo. Below is the information to set this up.
    1) Yahoo! Mail Settings (if allowed)

    Yahoo Incoming Mail Server (POP3) - pop.mail.yahoo.com (port 110)
    Yahoo Outgoing Mail Server (SMTP) - smtp.mail.yahoo.com (port 25)

    2) Yahoo! Mail Plus email server settings
    Yahoo Plus Incoming Mail Server (POP3) - plus.pop.mail.yahoo.com (SSL enabled, port 995)
    Yahoo Plus Outgoing Mail Server (SMTP) - plus.smtp.mail.yahoo.com (SSL enabled, port 465, use authentication)

    Freezes on the warm boot screen MC9000


    This can be for a number of reasons.

    First thing would be to try and cold boot the device:-

    Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger

    If that fails next thing would be to try and re-flash the operating system. This is done by using an SD card and loading the latest operating files onto it. The SD card slot is located under the keypad. A cross head screwdriver is required to remove the keypad. Search on symbol software download site for the latest. The download also has a readme with detailed instructions. Once the files are on perform a cold boot.

    Remove battery half way, hold power button and trigger, push battery in fully until click and then release power and trigger. Drop the terminal in a cradle so that it runs on external power.

    Hope this helps.
