Hi Kenneth,
Have you checked to see if the charge connector on the laptop is loose when you plug the charger into it? You can see if it is by plugging it in and wiggle it around a bit. The charge light on the laptop might stop blinking if its moved and contact is made.

Thanks,
Gary

It could be adapter.take out the battery and plug in ac charger.if it switches on then it could be the main board is not charging the battery up.

If it is orange or is blinking orange, the battery charge is low or expended. Remove the battery and re-install it. Plug in the AC adapter and connect it to an outlet. Turn on the computer.

When the battery status light blinks green and orange, the battery temperature is too hot for charging. Shut down the laptop, detach the AC adapter, and allow the laptop and battery to return to room temperature before attempting to charge the battery.

If the battery status light blinks orange rapidly, the battery itself may be defective.

get another ac adapter or check if the power dc jack is loose.

Dell or Panasonic? Your post has both listed.

If the blinking light on a Dell is yellow or amber or orange (somewhere in that color range) and continues to blink the entire time it is plugged into AC power (wall outlet) and when you unplug it from the wall the laptop immediately dies .... then you battery is dead and needs replaced.

If the blinking light stops after a while (perhaps a minute?) and then turns green while plugged into AC power, then it is successfully charging - or so it thinks.

When you unplug it from the wall, does it stay up and running?
If it runs, it's OK - just ignore the light and plan on getting a new battery one day, start browsing now. :)
If it dies immediately upon unplugging, then your battery is dead and needs replaced.

Hi there.
Sounds like the battery could be faulty.
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.
