    My laptop doesn't charge battery when it is on!!!


    I am running windows 8 pro wmc on my HP laptop. One month ago I have bought a new battery. From last one week, when I start my laptop it shows that "plugged it, not charging". When I shut down down, it started charging the battery. After a full charge, my laptop performs good and battery worked for almost more than 2 hours.

    Please help me. Whats the issue with my laptop. Thanks in advance for your help.

    Maybe you need to Calibrate the laptop to the new battery: Calibrate Laptop Battery

    Sometimes in the BIOS they have a utility that trains your battery. But you can do it Manually

    To do that, charge the battery to full capacity, then unplug your adapter and use your laptop until it has 5% or less of battery left. Then charge it full again, and drain it again. Repeat this process at least 5 times.

    Only 2 hours for a new battery is not good, you should be getting at least 3 if not 4 hours of use.

    If it will not charge while powered up, there may be something wrong with your Power Block on the laptop. There are chips on the motherboard that become unseated due to heat, and fans stop working. You got to take the laptop to a Laptop only shop and they can re-seat the chips, check your fan and clean the system. That may be what it needs. The places usually charge a couple hundred bucks to do it, it's hours of work.

    Also check the connector, while it is powered up, jiggle the power connector a little, see if it starts charging.

    Thanks to both of you my friends. I have taken your advice in my mind and I will do so as per as your suggestion. And then give you feedback about charging performance.

    Let me ask you this, when plugged in, does the system stay on? If so, it may be charging and not showing the status correctly in the tray.

    Well, I've seen HPs and Toshiba's that did this, try unplugging it and plugging it back in a few times, eventually it should start charging.

    Also, go through your advanced power settings, set your maximum Processor speed to 80% when on Battery, 100 for plugged in.

    Set the minimum CPU to 25% plugged in, Max to 100.

    There are a bunch of settings for battery as well, go through those make sure they are all set to default. I dont have a laptop so I cant remember what's all there.

    I did it. But there is no option to set CPU usage.

    It's there, under "Processor Power Management" in Advanced Power Settings. Open you power settings, and get into Advanced settings from there.
