IF the battery is bad the charge lndicator on the laptop will flash (But not periodically) it will be a constant on-off-on-off..... Best check would be to remove the battery completely and use the adapter/charger power supply only. If it still does not turn on then you either have a bad power jack connection or a more serious motherboard problem. Also is the green light flashing on the adapter/charger or is it the charge/battery indicator on the laptop?
Do you mean there is no sign of life in your laptop??? If yes then there are a number of reasons for it. The dead battery, but should run when plugged into mains. Dead power-on switch on the laptop. Bad BIOS chip. Disconnected motherboard. A bad BIOS chip is unlikely but a bad power-on switch is very likely. And for both these items you will have to open up the laptop. And then replace the power-on switch.
First thing check that the battery charge light is on when the battery and the charger are connected.
If it is it indicates that the power supply is charging the battery,
If it isnt it may indicate a fault with the battery or that the charger is not compatable with the laptop or that there is a fault with the charger.
If the battery is charging then try running the laptop on battery only without the charger and on charger only without the battery.
This will eliminate which one is faulty.
You mentioned that if you wiggle the cord then the light comes on again.
Check to see if the charger end plug is lose or the actual port on the laptop is lose.
If the charger plug is lose then return to seller and make sure they gave you the correct charger. if the actual port on laptop is lose then perhaps u got a bad connection and you need electrician or local laptop technician to open it up and solder properly on motherboard.
The plug in terminal that is soldered to a board inside the laptop has a loose solder connection. This procedure require opening the laptop and some soldering iron, and some solder. If you are not confident in doing this don't try it cuz you can mess up your laptop forever.
goto google enter "compact presario drivers" click on link to HP Support and drivers. once there, enter your product name/number. it should show you a list of all drivers available for your model. download your audio driver and reload it to your laptop. sometimes drivers get currupt and dont work right. hope this helps...good luck
Hi, can you use a multimeter?
If so then check on the power suply what the voltage output should be for that unit.
Then with the power turned on GREAT CAUTION MUST BE TAKEN AT THIS STAGE AS TESTING THE WRONG END COULD CAUSE ELECTROCUTION use the meter to test the laptop end plug only and see what power output you have.
If you can not do this then take the power supply to a technician and have it tested. If ok = dead battery, if not replace power unit.
