The blinking orange light means that there is a hardware failure. This could be anything from the power supply, the CD/DVD drive, RAM, hard drive or even the motherboard itself.

To begin troubleshooting this, first remove the power supply and use another one that is known to be working (if you have a second computer in the house, use its power supply).

Still have the orange light? Unplug all non essential components, one at a time to see which is causing the failure (CD/DVD drive, Hard drive). If there are multiple sticks of RAM, you can remove all but one, and begin testing these one at a time.

If all the above does not uncover the failed component, then the motherboard is most likely the issue.

When i turn on my Dell Inspiron 2400 Desktop Computer why won`t it start.


Is the computer plugged in to a known good power source with a known good power cord? Also, make sure the power is fully seated on both ends. When you press the power button are you getting any indicator lights? The power button itself has an LED that will be either solid green, blinking green, solid amber, blinking amber, or off. Do you hear any beeps?

Flashing amber light


Hi, on most Dells a flashing amber light on the power button indicates a problem with the PSU or a short on the main power rail, if this is the case you should have 2 flashing lights as well, 1 & 3.

E system 1212 Laptop won't switch on. Power


Laptops are so integrated that usually a system failure that involves power issues such as in your case where you cant get it turn on with anything on the screen mean the mainboard (motherboard) is damaged. This usually leads to buying a new laptop or paying for the board to be replaced which usually costs as much as the laptop.

Problem with extended battery


LED indicator for your laptop model
Steady Blue = Battery charged and AC adapter plugged in
Amber = Battery charging and AC adapter plugged in
Slow Amber Flash = <10% battery life
Fast amber flash = 3% remaining TPC will automatically go into hibernate
Slow flashing amber Adapter plugged in = Overheat condition

Do you have a multimeter to test the battery that you are using? check the output current of the battery.

Is the amber light flashing on the monitor?

If so, you should get your power supply checked.
