Question about Dell Dimension 2400 PC Desktop

Dell Dimension 2400 won't turn on

My Dell wont turn on.  The button on the front of the tower will turn red for a very short time when I push it, but the computer won't come on.  The monitor works fine and I've tried a different cord and tested the outlet the tower is plugged into.  Someone told me to buy a new power supply, but I think it might just be the button on the front of the tower.  I pulled the unit apart and carefully dusted everything and cleaned the contact point where is the button hits the switch on the inside.  Is there a way I can test the button, or should I just buy a new power supply?  Any help you can offer would be appreciated.  Thank you

    Dell XW8200 Server. Fans inop front panel red light blinks 3 times on power up. No DC voltage present on PS adapters. Replaced PS problem remains. Suspect Grounding or PS return problem but cannot confirm.

SOURCE: optiplex 170l motherboard to fit

Both systems use a Mitac Chassis, only real difference is the front bezel.

So one motherboard should fit the other.

SOURCE: how do you open the tower of a dimension 2400

If you look at the CPU from the back. On one side usually the left you will see a screw where the side wraps around the back. Some brands will use two screws. Remove this screw and then you can slide the side panel back toward yourself. Then you can turn the CPU exposing the open side. While your in there (make sure the unit is not plugged in) take a can of compressed air and clean your cooling fans and vents. Keeping a computer cool is important to keeping good performance up to where it should be.

SOURCE: My Dell dimension 2400 monitor doesn't work when

Hi! For dell machines when u unplug the video cable/VGA from the tower while the system is on it will show monitor self test.If you are seeing a black box moving around the screen it means that monitor is ok.Check connection between monitor and tower.Make sure cables are securely plugged in.Check if the tower is ok. There is a possibility that your monitor is ok but the tower is not.check the power button (whats the color) if amber/orange, this means there is something wrong the the tower. If its blue or white it means its ok.Also check if you are going to hear one beep, it means system is booting up properly. If tower is ok and you are using a expansion video card then try to use internal one, normally its the vga port above the usbs.If you are going to use onboard video card make sure you enable it first in bios.If all things fail, contact your manufacturer, if the system is under warranty then they will send a tech to check the machine.hope this helps...

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.

The battery is fully charged, and the ac adapter is plugged into the laptop, when i push the on button the laptop will not start


Remove the battery and power source. Remove the RAM and hdd. Power up with the power supply and it should do something. If it does, replace the RAM and hdd it should now restart. If nothing, check the GPU.

Bluetooth & sound


Generally, connecting phones via bluetooth to a laptop just allows for file transfer between the two devices. It is not to input sound from the phone through the speakers of the laptop. You would need a bluetooth audio device for that such as bluetooth speakers or headphones

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.

If you need any more help then please do not hesitate to contact us:-

How do i turn my bluetooth on?acer aspire 5044wlmi


For Acep Aspire 504x model systems that have Bluetooth built in, there is an on/off switch located in the front of the system.

For systems with bluetooth built in there will be two buttons next to each other just left of the mic and headphone ports.

The left of the 2 buttons is the bluetooth switch and the right of the 2 buttons is for 802.11 wireless.

If you only have 1 button then you do not have bluetooth built-in. You can also check to see if bluetooth is included by looking at the bottom, if Bluetooth is installed there will be a white FCC lebel with the name Bluetooth written on it.
