Check the port on the laptop where you plug in the adapter. Try to wiggle and see if you have a loose AC/DC input jack.
If yes, you need to have it repaired, unfortunately. If not, remove the battery then plug the adapter and see if you can see a light or if you can boot up the laptop.
You may try plugging it in on a different wall outlet.
Hope this helps.

My laptop is not powering on help


1.Connect the Ac adapter to a known good power outlet. Check the Power LED indicator on AC adapter (without plugging into the Notebook). We are only checking the power AC adapter to see if that is working.
2.If LED on the AC adapter is not lit (when unplugged from notebook), reseat the AC adapter brick and cable. If still there is no light on AC Adapter replace AC adapter and Power cord.
3.If LED on the AC Adapter goes off only after connecting to Notebook, the issue is with the motherboard. Replace Motherboard, DC-In port (AC adapter connector).
4.If the AC Adapter LED is always ON, take a technician's help and reseat the Power Button Board. You can refer to the Service Manual for details on how to reseat the Power Button Board. (NOTE: Before the notebook chassis is opened ensure all the power connections including battery and external devices are disconnected)

My laptops shut down when i put the adapter and doesn't get start up , but it's work normally with betray


Problem description:The laptop shuts off when AC power adapter is plugged in. The laptop works fine on battery power but as soon as you connect it to AC adapter, the laptop turns off.
Possible cause:1. Power adapter failure.
2. Motherboard failure.
Possible troubleshooting steps and repair solution:First of all, test the power adapter. Make sure the adapter outputs correct voltage. It's possible that the output voltage is not correct and the laptop shuts down to prevent the damage. Test your laptop with another known good power adapter.
If the problem still exists, even after replacing the adapter, most likely it's the motherboard failure. Replace the motherboard.

There's seems to be a short where the AC adapter goes into the Laptop. Loose parts in that area of the Laptop where the adapter goes in. It won't turn on. Maybe it's the battery.


Unfortunately, this is a frequent issue with laptops. Being moved around frequently can cause the AC Adapter to pull at the DC Jack on the laptop. If it is loose, it can mean there is a broken connection within the laptop. What you can try is powering the laptop on with it plugged in and the battery removed. If that doesn't work, I'd recommend going to your local Best Buy and picking up a universal AC Adapter. If that doesn't work, you can always return it, even if opened.

My laptop wont come on or charge


Please remove and clean the Battery terminals of the Notebook, make sure that the LED power indicator of the AC Adapter is glowing and output pin of the AC Adapter is properly connected to the notebook. The fault might be either with the output pin of the AC Adapter or Input DC socket of the Notebook. If the LED Power indicator of the AC Adapter is not glowing then the AC Adapter is not working and requires replacement. If the AC Adapter is working then please remove the Battery and turn on the Notebook by directly connecting to the AC Adapter. If the issue still persists, then it might be hardware issue of the Notebook and Service might be required. Please contact the manufacturer to initiate the service.

Check if the AC Adapter brick is getting warm when connected, if not then you need to replace the Adapter.

If AC Adapter brick is getting warm and still its not charging the Battery, please perform the following steps.

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30 seconds to 1 minute.
4. Reconnect the AC adapter and do NOT connect the battery now.
5. Turn on the Notebook power.

Note: With an extensive use of the notebook, some times notebook would store some static charges which indeed will stop the notebook from powering up or charging the battery.
The procedure to remove this static charges from the notebook is known as power drain.
Performing a power drain procedure will not effect any personal data or delete any pictures from the hard drive on your notebook.

If issue persists, contact Notebook manufacturer for further support.

best way is to just try out the battery on another laptop, or try another battery on yours. If the laptop is not very old, and I suppose yours isn't more than 2 years old, your battery shouldn't be dead.

If this doesn' t work. iyou said hte battery light flashes so the problem isnt the battery..the problem might be hte ac power adapter..if you have a warranty this would be a good time to call them. Try the power cycle first though this fixes the problems lots of the time

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.

HP DV2036ea i have a blank screen on the computer


Hello there

Description.

When pressing the notebook power button nothing is displayed on the screen or display. The cause of this problem may be a failed AC adapter, the memory modules (RAM) need to be reseated or a failed notebook system board component which will require an HP certified repair.

Below steps will assist in identifying the cause of the problem and suggest the best solution. Test the AC adapter Follow the steps below to determine whether the problem is related to the AC adapter or your notebook system board.
  1. Remove the battery and disconnect all external devices from the computer.
  2. Hold the Power button for several seconds, with all power sources removed. This drains residual power from the system, and may correct many problems.
  3. Connect the AC adapter to a wall outlet and plug the other end into the computer.
  4. Press the Power button to start the notebook PC.
If the notebook does not start or the display is blank then check the power indicator light or power socket LED. Check the power indicator light or power socket LED On newer models of notebook PCs, there is an LED or indicator light around the power socket on the notebook. Check to see if this light is on or off, when the notebook is plugged into AC power.The power indicator light or power socket light should turn on when the AC adapter is connected.

  • If the light does not turn on then the problem is most likely related to the AC adapter or the electrical source in your home or office. Go to the Light does not turn on section on this page.
  • If the light does turn on but the notebook does not start or the there is a blank screen then continue to the Light does turn on but the notebook does not start section on this page

The light does not turn on when the AC adapter is connected If the power indicator LED is off, the AC power adapter may need to be replaced. To determine if the AC power adapter needs to be replaced follow the steps below:
  1. Ensure that the AC adapter is plugged directly into a known working wall outlet.
    NOTE: To check the wall outlet, plug in a different known working device like a light, radio etc.
  2. Check all of the following connections:
    • The connection from the power cord to the wall outlet.
    • The connection into the power adapter from the power cord.
    • The connection from the AC adapter to the notebook power socket.
  3. Press the power button again to test the notebook PC.
If the power indicator light still does not turn on, then the AC Adapter needs to be replaced. Contact HP Service and Support for further assistance. Power socket LED or power indicator light is on but the notebook does not start If notebook power indicator light (LED) is on, the AC adapter is working correctly. The problem is a result of a hardware failure in the notebook itself. In some cases, reseating the memory module (RAM) may solve the problem.
