See if you can locate another ac adapter and try it. i would almost bet that you have a bad AC adapter. The second most likely suspect would be the dc jack where the adapter plugs in. Plug in the adapter and see how much "wiggle" room you have. If there is alot of play then it probably is your dc jack. That is a shop fix.

Dell inspiron 1525 - plugged in not charging shown on battery icon. Battery power light blinks 4 times amber then once blue.


The diagnostic procedures from the Dell User Guide are as follows:

Total Power Failure When Using a Battery
If an AC adapter is not connected to your computer, the computer's power source
is a battery. If the battery indicator flashes amber or is a steady amber, the
battery needs to be charged. If the battery is flashing green and amber, the
battery may be defective. To troubleshoot this problem, use the following
procedure.
1. Turn off the computer and peripherals, and disconnect them from AC power.
2. Reseat each installed battery by removing it and then replacing it.
3. Turn on the computer. Does the green power indicator light up?
Allow one minute for the computer to initialize its components before checking
for signs of power.
Yes. Continue to step 4.
No. Use the AC adapter to connect your computer to AC power. If the computer
operates normally when using AC power, go to step 7. If the computer does not
boot when using the AC adapter, see the previous subsection, "Total Power
Failure When Using the AC Adapter."
4. Does the battery indicator flash amber or show a a steady amber light?
Yes. The battery needs to be charged. Go step 5.
No. Go to step 7.
5. Connect the computer to AC power, and fully charge the battery.
For instructions, see the topic titled "Charging the Battery" in the online
System User's Guide.
6. As the battery charges, does the green battery indicator light up?
Yes. Go to step 9.
No. Go to step 7.
7. Is the battery indicator flashing green and amber?
Yes. Your computer may be in a hot environment. Charging the battery in this
condition may affect the life span of the battery. Continue to step 8.
No. The problem is resolved.
8. Disconnect the computer from AC power. Is the the battery indicator still
flashing amber?
Yes. You may have a defective battery. Continue to step 9.
No. The problem is resolved.
9. Remove the battery, and press its test button. Is the uppermost indicator in
the charge gauge of the battery flashing?
Yes. You have a defective battery. Continue to step 9.
No. The problem is resolved.
10. If a spare battery is available, fully charge it, and then install it in the
computer.
11. Turn on the computer. Is the power indicator off?
Yes. Your original battery is defective. Call Dell for a replacement. (See
Chapter 5, "Getting Help," for
instructions.)
No. Call Dell for technical assistance. (See Chapter 5, "Getting Help," for
instructions.)

Dell latitude 100L power light flashes green as if


It sounds like you have a bad AC adapter . When you plug it in to the outlet in the wall and into your computer , do you see a charge indicator light on the computer? I'm asking you this because even with a bad battery your computer should operate without any problems with the AC adapter plugged in.

My Dell Inspiron B130 will not turn on


The battery is critically low, indicating that it is not getting a charge from the AC adapter. If the system will not power on from the AC adapter, then the motherboard power connection is suspect.

Motherboards are about $100 on EBay

I have a Dell D600 (PP05L), its not powering up no lights. I noticed on the power adapter the green light goes out when plugged into ac power. What could be wrong here? please help


Hook up your power adaptor to ac power without it being hooked up to the laptop and see if the green light stays on. If it does then you know your adaptor is okay. if your adaptor is only hooked up to ac power and the green light still turns off then you know your ac adaptor is bad.

Take out the battery from your laptop. Now hook up the ac adaptor to the laptop and if it stays green then you know your battery is bad but you also want to make sure you can get your laptop to turn on. Hopefully it will turn on with only the ac adaptor hooked up to it.

Orange and green light flash


The flashing battery light is an indication that the system is attempting to charge the battery. The orange light indicates a problem charging one of the battery cells. This usually means that the battery either needs to be recalibrated or replaced. To recalibrate the battery just use the system until the battery is dead, then recharge and repeat the process twice, after which time the battery should be recalibrated. If this doesn’t fix the flashing orange light then the battery may need to be replaced.

hope this helps
