HP Pavillion dv6500 won't charge

My computer charger broke and I just bought a universal charger at Best Buy today (Rocketfish AC Power Adapter). I tried every tip, and the only one that (M5) simply keeps the computer on, but refuses to charge the battery at all. I jury-rigged the old charger in hopes that putting a little bit of charge in the battery would help jumpstart the new charger. I let it charge to about 40%. No joy. Is this charger just not compatible with my notebook or can I make it work somehow?

Compare voltage and current (amps) from the original to the new. If the new one is different (voltage is lower, or current substantially lower), then it might not be an adequate replacement. If these are near identical, and you have the correct sized tip, there shouldn't be a problem with the new unit. Obviously, you could get an exact replacement supply $$. Also check online for replacements.

AC adapter 4750z


The solution to your problem lies in one of the following three areas:

1.) Your charger is faulty and is therefore not able to pass power to your laptops battery.

2.) The charging connector on the laptop has come loose from the contacts. Therefore a bad connection.

3.) Your battery is faulty.

I think possibility 2 is the most likely, although you will have to test possibility 3 by removing the battery and plugging in your charger and seeing if the laptop powers on.If it does power on then that rules out possibility 1 and 2 leaving a faulty battery.

If you need to buy a new laptop charger, the following to adapters are for your reference:

My Toshiba AC/DC Adapter model number ADP-75SB AB for my satellite computer is not working anymore. I have tried different troubleshooting efforts but all have been unsuccessful in getting my computer to...


Hello,

Is the ac adapter detected?

If YES, and it doesn't charge the battery, but it turns ON the laptop it means that the battery is the one not holding a charge.


If NO. Try to change the power cord that goes to the wall (that part is detachable) with good known power cord. If it does the same then definitely there's a problem with the ac adapter. You can contact the Toshiba sales department (1-800-8674422) or toshiba direct (1-800-3160920).

If the computer powers ON, both ac adapter and battery are detected but no display, then the problem is the system board.

I have a HP/Compaq 6510b laptop computer and it will not turn on...I have the charger plugged in and the only thing happening is the green light periodically flashes...Is the battery bad?


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?

Asus netbook ac power cord adapter stopped working...no blue light on...not charging computer...what to do and need new one?


You need a replacement AC adapter, it's very cheap online.
1)Output Voltage is within +/- 5% of your old charger's output.
2) Output Current is the same or higher than that of your old charger.
3) Connector tip must fit securely into your laptop.

Does not charge


hi,

you can try to conect the laptop directly to the power outlet without using the battery just to verify if it the battery or the charger itself..If it still power up the laptop,that means that the adapter is still working,if not,well obviously,its the battery itself


thanks

Hi there, When plugged in nothing happens. What could it be?


Only a few things come to mind:

1. The plug on the MB is defective
Solution: Have the plug on the motherboard replaced

2. The universal power adapter is defective
Solution: Buy an ASUS power adapter and test it out. If it doesn't work, return it. If it does, then get rid of the universal adapter.

Good luck
