Welcome to Fixya!

You can run the computer by just using the power adapter. Take out the battery and turn on the computer just using the power adapter. If the computer wont turn on then possible problem would be the power adapter itself or the socket where you connected the power adapter to your computer.
You need to send the computer to Lenovo depot repair center for repair.You may try to use other lenovo adapters just to check if the adapter is the problem.

Thank you for using Fixya!

hi,

You said laptop is working fine if just using the battery,that means that there is nothing wrong with the battery itself. Can yu please try to connect the laptop directly to the power outlet without using the battery just for the mean time,remove the battery and connect the AC adapter directly to the power outlet then power on the laptop,if nothing happens,that means that there is something wrong with the AC adapter itself or the power port on the laptop.
Hope this will help...

Laptop battery is not charging


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.

BOOTING PROBLEM


If the computer will not power on:

  1. Make sure the power cord or AC adapter is plugged into the computer and into an electrical outlet that is live.
  2. If it is plugged into a power strip or surge protector make sure it is powered on.
  3. Try using a different electrical outlet.
  4. Check voltage setting on power source (AC Adapters are auto switching).
  5. Perform a power reset on the computer.

To perform a power reset:

  1. Unplug and remove the AC adapter and battery, or power cable from the computer.
  2. Press and hold the power button on the computer for about 30 seconds.
  3. Release the power button and plug the AC adapter and battery, or power cord back into the computer.
  4. Press the power button and see if the computer powers up.
  5. If that does not work, try a different AC adapter, battery, or power cable and repeat these steps.

If the problem persists the computer may need service. You may need to contact Acer support.

hello

shut down computer - unplug power cord from laptop - remove the battery from laptop - plug Ac adapter into computer and Ac outlet (wall)
turn on computer
if computer does not turn on, replace the AC adapter and cord - then place battery back into computer
plug in new Ac adapter and cord - recharge battery - if orange light stays on after 4-6 hours of charging battery, you need new battery as well - replace battery, charge it up and it should be fine

if you have attempted these steps before and no change occurs, then you may have issue with power connection in computer - locate a service centre to replace power connection on computer

Turn on but the ac light don't work


first of all the battery error is with the laptop battery and not with the CMOS battery, if your saying that the light indicator for your ac adapter is no longer litting up and it would normally does, then i would suggest that try plugging it on a different ac outlet or double check if the power cord that goes to the wall outlet going to your ac adapter itself is properly plugin or seated. After you double check on those troubleshooting step and still has the same problem you could also try power draining your computer by removing the battery and unpluging the ac adapter and press and hold the power button for 15 seconds then plug it all back and try to turn on computer. If you still have the same issue after all those TS step you could try using a known good ac adapter or you could consider replacing it or might as well call their tech support hotline if your still under warranty so that they would replace it for free (Lenovo Thinkpad support: US/Canada- 1-800-426-7378, Australia - 1-300-880-917. BTW Im a Lenovo technician thats why i know this information and troubleshooting step and this what they would ask you to do if ever you're going to contact them for support, so when you call them after doing all this TS step you can just ask a replacement ac adapter for you laptop. hope it helps..

I have a compaq presario 700 laptop that is no longer charging.


The notebook battery may have a defect if it will not power on the notebook and if it will not hold a charge. The battery indicator light on the notebook either does not light or always blinks orange. The notebook operates correctly when connected to the AC adapter.
A battery that will not charge may be the result of an AC adapter failure, a system board failure, or a battery failure. Perform the steps below to diagnose the failure.
Troubleshoot the power supply
To verify that the AC power supply is functioning properly, follow the steps below.

1.
Plug the AC adapter directly into a functioning wall outlet, and plug connector into the computer. Do not plug into a power strip, surge protector or secondary power source.
2.
Verify the following operation and take the appropriate action:
*
That all power cord connections are secure.
If the AC adapter connection to the notebook is loose, the connector may be damaged and require repair. Contact HP service and support for further assistance.
*
That the power button or power LED is lit when the computer is on.
*
That an LED on the AC power supply adapter is lit when plugged into an AC wall outlet (not available on all AC power supply adapters).
*
That the AC power supply adapter is the correct type.
Different notebook models require different AC power supply adapters. You will need to know the Product Number of your notebook to determine the Part Number of the replacement part. Click Start > HP Help & Support to view the product name, product number, and serial number that you'll need to have to speak with HP Customer Service.
View the See Also section for information about locating HP Help & Support in your operating system.

Troubleshoot the System Board
If you've verified that the AC power functions properly, troubleshoot the PC's system board by following the steps below.

1.
Remove the battery, and keep the notebook connected to AC power.
2.
Press and release the Power button to start the computer.
*
If the notebook PC powers on , then the AC adapter and system board are functioning properly. Go to Troubleshoot the battery .
*
If the Power LED is off , then the AC power adapter needs to be replaced. Contact HP Service and Support for further assistance.
*
If the power LED is on , but the notebook PC does not power on, then the notebook PC needs to be repaired. Contact HP Service and Support for further assistance.
3.
Shut down Windows by selecting Shut Down from the Start Menu.

Troubleshoot the battery
If you have verified the AC power supply and system board are functioning correctly, troubleshoot the battery by following the steps below.

1.
Insert the battery into the battery compartment on the bottom of the notebook PC.
2.
Connect the AC power supply and allow the battery to charge for 15 to 30 minutes.
NOTE: The Battery Charging light should be on while the battery is charging. If it is not on, check the AC power adapter connection to the notebook PC.
3.
Unplug the AC power adapter cord from the notebook PC.
4.
Press and release the Power button to start the computer using only the battery as the power source.
*
If the PC does not power on, then the battery needs to be replaced. Contact HP service and support for further assistance.
*
If the notebook PC does power on, the battery is functioning properly.
NOTE: If you have purchased a second battery for your notebook PC or you have access to an identical battery, you can also check the battery by inserting the second battery into the PC and performing the Troubleshoot the battery steps again.
