Question about Dell Dimension 2400 PC Desktop
I have an amber light on LED A and a green light on LED B no light on LED C and a green light on LED D. I was wondering what that could mean I looked on all the troubleshooting pages at DELL but it has nothing for these lights.
The led lights you see is actually a diagnostic light which has an equivalent meaning there should be actually 4 led lights you see is it a yellow green green green pattern and this is at the back of your computer? if that is the case it could be an indication that there is a device inside your computer that is malfunctioning. you will have to strip down your computer. remove all that is connected to the motherboard (hard drive, cdrom, memory, expansion card if any) disconnect the mouse, keyboard and monitor as well. should you hear a beep or the light changed at the back it means your motherboard is good and the absence of memory is being reported by the beeping sound. try to connect the device one by one
now if you are referring to the light at the dell logo infront it is just a monitoring light to indicate if your computer is turned on and the right side light is whether your hard disk is doing an activity

The unit has LED activity indicators on the front of the case provide a status display indicating error conditions, transmission, and network activity for the 802.11a (amber) radio or the 802.11b/g (green) radio.
802.11a Activity LED Amber
The amber LED flashes three times per second until firmware is loaded. During boot, 802.11a mobiles cannot associate. After adoption, the amber LED is steady or flashes with 802.11a radio traffic.
The amber LED flashes once per second if an error prevents the 802.11a radio from operating normally.
802.11b/g Activity LED Green
The green LED flashes three times per second until firmware is loaded. During boot, 802.11b/g mobiles cannot associate. After adoption, the green LED is steady or flashes with 802.11b/g radio traffic.
The green LED flashes once per second if an error prevents the 802.11b/g radio from operating normally.
From this, it appears that the 802.11A radio is malfunctioning.
