Question about Compaq Presario Notebook

I was working on a paper and my laptop needed charged so i plugged it in and it showed it was charging so i continued to type. A few hours later my laptop said it needed charged again though i was still plugged in. Then my Compaq Presario cq61-313US shut off and i havnt been able to turn it on since. The only thing that happens when i press the power button is the light flashing a couple of times. I just want it to turn on again, please help!

When this happens, you may be dealing with a power adapter that has gone bad. Check to see if it's putting out the required voltage ~18-19 volts.
You could be dealing with a broken DC-in jack. This can be fixed, but with difficulty (it involves soldering on the motherboard.
You might have to replace the motherboard. First try to start the computer with the adapter connected, but the batter taken out. If it starts and works, then it's a bad battery.

    You'll need a voltmeter. Most adapters have the positive on the inside and negative on the outside of the part that plugs into your computer.
    Sounding like your adapter is bad from your response.

I have new laptop how many hour battery charge first time

First Time Charging
  • The amount of time it takes for your battery to fully charge depends on many factors, like your battery type and operating system. Many newer laptops will charge in 15 to 20 minutes, while others can take a few hours.

    When you're charging your battery for the first time, charge it fully before using your laptop. You may have to go through a battery cycle a couple times before your battery begins performing at its maximum capability. To do this, charge your battery fully, let it discharge to about five percent, and then fully charge it again

    We purchased a Rascal 300 two months ago that worked just fine. We seen proof that new batteries had just been purchased. It has a built in charger and we have kept the batteries charged. The charger now...

    Here's a link for the owners manual for the 300 model. Click on it and it will open as a PDF document that you can print.

    The ammeter back in the trunk should be registering when you plug the scooter in. If it isn't, this doesn't mean that it isn't charging as the meter itself may be bad. Put it on charge for a few hours and see if the "fuel guage" on the top of the tiller comes up to full. If it does, than your charger is okay and you just need to ignore the ammeter not working until it doesn't charge at all anymore, then the charger is bad. Note too, that later on when the batteries get weak and you can only go a little ways, that it still means your charger is okay, batteries not. Even bad batteries well show a full charge, but they won't take you far at all. If the batteries don't show a full charge after a few hours, then you need to replace the onboard charger.

    Good luck
