Question about Compaq Presario 700 470024-192 Notebook
I am not sure if it is the power cord or the battery. The cord may be a little bent but it still fits. However the computer will not charge.
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.
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.
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.
