When I plug in my ac adapter into my computer to charge it the green light turns off and won't charge my computer

Step by step troubleshooting.
Verify power outlet is good
Verify power adapter is good
verify connection to computer is good
fully charge battery
test
=======do this
Check power source, plug known good light into AC receptical.
If AC cord has connector to power block verify it is properly seated.
plug adapter into AC outlet
Verify Power is present at power connector with another similar computer or voltmeter. (12V to 20V)
When plugged into computer, charge (not power) indicator MUST light either red, amber, or green. If not, connector on computer may be broken.
leave overnight or until charge light is green
turn on normally.

most likely causes:
- loose connector
- broken wire from power adapter
- broken power plug on computer.
- anything else is probably beyond ur capabilities to fix.

If it\'s only two months old it may have a defective charging cable or adapter. If it\'s a new purchase and you can return it. To check to see if it might be the adapter and not the charging cable you have a few cheap ways to test this out.



General charging recommendations.



If you get power leave it on charge at least 3+ hours. This is the minimum time required if the battery is totally drained. If the Nook turns itself on during this process manually turn it off. The battery charges faster and more deeply if it\'s truely powered down. Charging more than 3 hours won\'t hurt it. In fact some manufacturers claim leaving thier products on charge for an additional hour after the charging light glows green is good as it leaves a slightly deeper charge on the battery. Also I believe leaving it alone for that hour allows it to cool the battery. Most manufacturers also recommend tottaly draining the battery at least once a month and then fully recharging it 1+ hours after charging light is green. They claim this helps the battery maintain a healthy charge and extends the battery life. Simply disconnect any charging cables, turn the unit on and just let it set. Don\'t touch it peroid just leave it alone until it turns off because the battery is totally drained. Then just plug it in and leave it. Only if the unit automatically turns itself on do you manually turn it back off.



Well that\'s about in in keeping the battery life and charge at its maximum.



If your AC power adapter has gone south there are only three ways to get around this. 1. Purchase a generic AC to USB adapter. 2. Purchase a genetic DC to USB adapter. Most of these can be cheaply purchased at most drug stores ect.. these days. You can even get DC to USB ones at dollar stores such as Dollar Tree. Good way to maintain your battery if your AC one goes south or you lose house current.



One other way to charge your battery is to plug the USB cable into your computer. Some manufacturers don\'t recommend this as this more often than not doesn\'t fully tank up your battery.



You can also get replacement charging cables at the same place you got the adapters. Places such as Walgreens, or CVS often have these at around five dollars a pop.

Hello,
If the battery won't charge and the laptop won't turn on but the ac adapter works with other laptops, then the problem is the port where you plugin the ac adapter. Some of the laptops has it built in to the motherboard. So you might need to have it repaired by a technician. Or if the laptop is still in warranty, you might need to send it to the manufacturer to have it repaired or replaced. But if the laptop works without the battery, or it will turn on but the battery indicator is not lighting up, you're facing one of these problems.
1. The battery itself is dead. 2. the battery bay is loose 3. the battery itself is loose
Hope this helps...

THE BATTERY LIFE TIMED OUT.TRY IT ON NEW BATTERY FOR TURNING ON THE SYSTEM.THE CHARGING ADAPTER MAY BR ALSO A PROBLEM TRY TO CHECK IT AC VOLTAGE LEVELS .

As you yourself have said, this is NOT a camera. For help, I would advise you to post this in a forum dealing with computer equipment.

Hi, this information represents a basic troubleshooting guideline. Refer to your user guide for specific charging and connection instructions. Manuals may be available online in the Support Web site of HP.

Remove the battery from the computer.
Confirm the battery contacts are free of any foreign material that may prevent charging.
Reinsert the battery into the computer.
Verify that the AC adapter cord is properly connected and plugged directly into a known working AC power outlet.

NOTE: If the battery charges correctly when the AC adapter is plugged directly into an AC power outlet, but not when plugged into a power strip or surge protector, the problem is with the power strip or surge protector and not the computer battery or AC adapter.

Verify the correct AC adapter is being used.
Ensure the AC adapter box power light is on. This will be an illuminated green light.
If the AC adapter power light is not on, the AC adapter and power cord will need to be replaced.
Verify the charging indicator is illuminated on the computer.
If the issue still exists, install a different compatible HP battery, if available.

NOTE: If a replacement battery charges and operates correctly, the problem is with the first battery.

If neither the original nor a replacement battery charges, service may be required for the computer.

I had the same problem, I removed the bettery while it was still plugged in, tested it, then plugged it back and and now all is fine.
or you may try 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.

computer.
11. Turn on the computer. Is the power indicator off?
Yes. Your original battery is defective - please look for a replacement. Hope it helps.

which green light?

light from the ac power adapter or the light from the battery?

if ac power adapter you are referring to try a diff power wall socket if ac power adapter still off then replace ac power adapter alone.

if battery light is off but the laptop works fine with ac adapter alone try updating the laptop BIOS.

if ac adapter light turns off when it plug to the laptop replace motherboard.

hi bro what u need to do is ... understand when u plug in the ac adapter the light on the ac adapter goes off and whne u unhoook it it comes on .. right there is a possible static charge in the mobo bcoz of which the ac current is nt able to flo on thru the wires to the motherboard .. what u can do is turn ur laptop off completely unhook the ac adpter and take off the battery as well press the power button for 15 sec press and hold it do this xcersice .. hook every thing up and try to charge the battery again it should work .....second possible thing can be may be the connectors on the mobo can be bad on the pin in the prong on the ac adpter must be twisted ,,, so check for that as well ...if still no go then either problem with the onboard power connector on mother board or the whole mother board power aseembly IE replace the mobo ....
cheers

From Toshiba, try step-charging the battery or Battery conditioning procedures:

Batteries don't last forever. All types of batteries gradually lose their ability to hold an electrical charge as they age. Eventually, the computer's battery charge indicator may show that the battery contains less than a full charge, even though the battery has just been fully charged. The computer will then not run for as long a time from the battery as when the battery was brand new.
You may prefer to simply replace the battery if this happens, but you may also wish to try 'step-charging' the existing battery per the following instructions.
This procedure should work for the battery in any Toshiba notebook. Follow it only when you find that the computer will run from the battery for just a short while.
Check the User's Guide for more specific information about charging the battery in your computer .

Procedure

Step-charging the computer's battery

1. Unplug the AC adapter from the computer, and turn ithe computer on. Let the computer run from battery power until the computer turns off, indicating that the battery is fully discharged. Time this interval, but not with a software clock running on the same computer.
   
   
2. Remove the battery pack from the computer.
   
   
3. Unplug the AC adapter from the computer.
   
   
4. Wait at least 30 seconds. The first time through this procedure, use a soft cloth to wipe the battery pack's contacts and the AC adapter's plug.
   
   
5. Re-insert the battery pack.
   
   
6. Plug into the AC adapter into the computer again and check the fit of its plug in the wall outlet, making sure the connection is secure.
   
   
7. With the computer turned off, let the battery charge until the battery status light or icon glows green, or otherwise indicates a full charge.
   
   
8. Unplug the AC adapter from the computer.
   
   
9. Remove the battery.
   
   
10. Wait at least 30 seconds, then re-insert the battery.
    
    
11. Plug the AC adapter back into the computer.
    
    
12. Let the battery charge again until the battery status light turns green or otherwise indicates a full charge, again.

Repeat this procedure, starting from step 1, at least three times. Each time, check to see if the computer runs longer from its battery than the previous time.

Battery Conditioning:
IMPORTANT!! Interruptions in the charging cycle can be responsible for an issue called "memory effect" which may reduce the battery's charging capacity. Whenever you suspect the battery performance is not at it's optimum you should try using the following "Battery Conditioning" procedure.

Before you start: Turn off your battery saving features temporarily.

***IMPORTANT*** Repeat the following steps 2-3 times!

1. Unplug the power cord from the computer
2. Turn the computer on and let it run until it shuts itself off.
   Note: Using the CD-ROM to play an Audio CD will speed the discharge.
3. Plug in the power cord (While the system is off) charge the battery until the battery light changes from flashing green to solid green
4. Remove the battery for 30 seconds and then replace it.
   Note: If the battery light isn't lit, wait a few moments, if it still does not light check your power connections.
5. Continue charging the battery until the battery light turns solid green once again.
   **REPEAT THIS PROCEDURE 3 TIMES**
