LED trouble lights

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.

    I gathered that, well for the most part, I know these lights are there to let you know how your system is doing, but I was looking for a little more information like: what does the amber light on LED "A" mean and the no light on LED "C" this would give me more of an Idea as to what is going on with the system ie: is the harddrive going bad? or is it the motherboard??? etc.

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

I have a motorola AP-300 which keeps on blinking amber light when i turn it on. how can i reset it or what's wrong with the AP?


From the installation guide for this AP, I find the following:

LED Indicators

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.


Here is the Motorola support web page for this device.

Stuck on amber light will not turn on


An amber light normally means that there is no signal getting to the screen, if it was stuck in standby then the LED would be red.

Please check your connections to cure the fault

Lights on Rechargable Lantern.. Swissgear SG66301


I don't know how to solve your problem but, the three lights mean this:
Red LED light indicates the battery is being charged
Green LED light indicates that the battery is fully charged
Amber LED light incidates that the battery power level is low - the battery needs recharge.
Do not recharge you battery over 24 hours.

But to answer your question here is what the difference between the green light and the red light are:
1. X-Band Signal Indicator—A green LED lights and blinks to
indicate the presence of an X-band radar signal. The blink rate
increases as the radar source gets closer. A distinct audio alert is
also heard.
2. K-Band Indicator— An amber (orange) LED lights and blinks to
indicate the presence of a K-band radar. The blink rate increases as
the radar source gets closer. A distinct audio alert is also heard.
3. Ka-SuperWideband Signal Indicator— A yellow LED lights and
blinks to indicate the presence of a Ka-SuperWideband radar
signal. The blink rate increases as the radar source gets closer. A
distinct audio alert is also heard.
4. Laser Signal Indicator— A red LED under L lights and blinks to
indicate the presence of a laser signal. A distinct audio alert is also
heard.
5. SWS Signal Indicator— When an early warning hazard or
informational signal is detected, the yellow SWS LED begins to
blink and the amber K-band LED lights. A distinct audio alert is
also heard.
6. Power-On Indicator— A green LED under P lights to indicate
power is being supplied to the unit and the unit is turned on.
7. LED Signal Strength Meter—Four LEDs give an accurate visual
indication of the strength of radar or laser signals.
8. City Mode Indicator—A green LED under C lights to indicate
that you selected City Mode.
9. Auto Mute Indicator— A red LED under M lights to indicate that
you selected the Auto Mute feature.

Please make sure you give me a rating and I hope this helps,
