My Powershot G 9 will not turn on. I charged the battery when I noticed it wasn't on. The green light says it is fully charged. This just happened today

Question edited for clarity, full make model (what it is).

Did you follow Section 9 about fully charging the battery, pressing and holding the button?

Charging Instructions 1. Plug the charger into the mains - the charger indicator light will be green.
2. Turn on the battery by press and holding the power button until the green light is illuminated.
3. Plug the battery into the charger. The charger light will turn from green to red to indicate the charging process has started.
4. Once the battery is fully charged, the charger status light will be

Hit the small reset button on back,I used a toothpick

Directions say green light indicates that the battery is fast charging only,it does not indicate at exact point of full charge. I let my batteries charge for 12 hours for the first time charging,found out myself the same way. Try that and you will notice the difference.

Janice check your charger it could not be charging the batteries. Now always charge your batteries overnight while you sleep When you get up lights on the charger should be red and green if they are red and yellow then the charger hasn't fully charged the batteries and overnight should be more than enough time to charge fully. This could indicate a bad battery remember new doesn't always mean good. Like they say always charge before use and this goes for new batteries too you need to charge new batteries nightly for 10-15 days before they start operating at 100%. If when you plug in the charger before bed and the lights are red and green then there is a problem with the charger or the batteries or the charger circuit Hope this helps you

the charger light detect the battery level charge, shows red when charging and green when fully charged.when the charger light is not lit,may be the battery dosnt hold any charge that means its likely that the battery is defective

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


good luck

When batteries are placed into the charge mode, the red light will come on.
When fully charged, on those units with a green light, the green light will be an indication that your batteries are charged and if your unit has no green light, the fully charged indication will be when the red light turns iff.

Take out the battery and put it back and than recharge again. Some times in case of G5 it happens that the camera battery is not properly charged and the indicator shows that its fully charged (i.e. Green light) In such cases battery need to be taken out and than put back again and recharged
