How to Recalibrate a battery


SYMPTOMS- Short discharges and recharges do not fully synchronize the battery's fuel gauge with the battery's state-of-charge. This can result in the amount of power available in one cycle being less than expected or the battery meter being inaccurate.
Under normal usage, batteries should be calibrated a minimum of once every 3 months. Your battery can be calibrated by following these steps:

I - Disable the Windows Power Management

1. In Windows, right-click the Desktop and select Properties in the menu list.
2. Click the Screen Saver tab and then click the Power button.
3. Under Power schemes, select Always On in the drop down menu.
4. Under Settings for Always On power scheme, select Never in each of the drop down menus.
5. Click OK on the Power Options Properties window and then click OK on the Display Properties window.

II - Fully charge the battery

1. Connect the AC adapter to the notebook.
2. Charge the battery until the Windows battery meter is at 100%.

III - Fully discharge the battery

1. Remove the AC adapter.
2. Keep the notebook on until the battery has completely drained and the notebook automatically turns off.
3. Connect the AC adapter to the notebook.
4. Keep the AC adapter connected to the notebook until the battery has completely charged.

IV - Enable the Windows Power Management

1. In Windows, right-click the Desktop and select Properties in the menu list.
2. Click the Screen Saver tab and then click the Power button.
3. Under Power schemes, select Portable/Laptop in the drop down menu.
4. Click OK on the Power Options Properties window and then click OK on the Display Properties window.

Cannot turn on my laptop only the start button light turns on but no screen display and a few noises help


This is only the first of many things you may need to do to determine the fault. But it is a process for determining the exact cause.


Make sure the ac adapter is correctly plugged into the notebook and into the power cord.


If everything is plugged in correctly and it still will not power on, follow these steps to complete a 'power reset' of the notebook.

  1. Unplug the ac adapter. Keep ac adapter unplugged.
  2. Remove the battery and keep the battery unplugged.
  3. Hold the power button down for 15-20 seconds. (Nothing will appear on the display and none of the lights will light up.)
  4. Release the power button and plug in the ac adapter ONLY. (Please note that a power indicator light should be lit on the ac adapter when it is plugged in).
  5. Normally power on the notebook.
  6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
  7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.

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.

  1. Unplug the ac adapter. Keep ac adapter unplugged.
  2. Remove the battery and keep the battery unplugged.

  5. Normally power on the notebook.
  6. If the unit does not power on, remove the ac adapter and insert the battery into the system.
  7. Plug the ac adapter back into the system, the battery charging indicator light will light up.
    If the battery charging indicator light does not light up, the ac adapter may not be providing proper power to the unit, and may need to be replaced.
Also, depending on whether your power went down "clean" (quick and stayed off), or went down and quickly came back on and off many times. Or when it came back on "clean" (came back on quick and stayed on), or it came on then off many times, your power supply may have been damaged from the power surges Are you having any problems with any other appliances?
