Solve Problem of Laptop Batteries for You


When my laptop is plugged in, it powers up fine, and I can unplug it and use it normally. But it will only turn on if connected. Any ideas how to get it to start without being connected to the laptop power supply?


  • RTQ read the question. It runs off battery. just wont startup.
  • How old is the laptop? Is this a new problem or it has always been that way? Most likely explanation is that your battery is deadÖÖif that is the case the only solution is to buy a new battery.
  • Because of your laptop battery fully drained that is why it start only when your laptop is plugged into power supply so change your battery.
  • Battery dead may be? try unplugging it, removing the battery, and letting it sit for few minutes , then booting insert battery and boot up again.check the bios settings? also reset CMOS battery?
  • Q2:

    My MacBook Pro wonít charge. It is a Mid-2010 2.4 GHz Core i5 model with 4GB of RAM, 320GB HDD and running 10.7.2. The mag-safe adapter lights up green when I connect it but intermittently goes on and off. The MACBOOK PRO 15 battery level light on the side of the computer flashes one light only.
    Also, as bad luck would have it, I was taking system updates ( I had just bought this laptop used and it was due for major updates) when I noticed the battery was very low. I connected the power supply and thatís when I noticed the problem. I just barely had time to stop the updates before it died right in the middle of them. Iím hoping this did no further damage.
    Obviously, it isnít under warranty and Iíve already spent several hundred dollars purchasing it. Iím hoping this isnt going to cost a fortune to fix. Please, does anyone know what is wrong with and how to fix the newest addition to my Apple family?


    I wonder if it is SMC causing it. I would try to remove the battery (If you can) and reinstall the battery. After that start the mac up as normal and see if there are any changes.

    If that doesnít help any try this (If you can remove the Battery):
  • 1.Shut down the computer.
  • 2.Disconnect the MagSafe power adapter from the computer, if itís connected.
  • 3.Remove the battery.
  • 4.Press and hold the power button for 5 seconds.
  • 5.Release the power button.
  • 6.Reconnect the battery and MagSafe power adapter.
  • 7.Press the power button to turn on the computer.
  • If you canít remove the battery:
  • 1.Shut down the computer.
  • 2.Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
  • 3.On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
  • 4.Release all the keys and the power button at the same time.
  • 5.Press the power button to turn on the computer.
  • Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.


    I have an older model Toshiba Satellite. The left mouse button has been loose for a while now, but yesterday it sunk deeper down into the laptop and thatís when it shutdown.
    I tried powering it back up but nothing happens. No lights no sounds nothing. I take my time and pull the mouse button back into position thinking that would fix it but no, the laptop will still not power on.
    All around the net Iíve seen a method of taking the TOSHIBA SATELLITE 6000 battery out and unplugging the power cord then holding power before inserting the battery again.
    I want to try this to see if I can get power long enough to backup my files.
    Iím concerned though that when I remove the battery it might affect the hard drive Can I take out the battery and try the fix without risking my hard drive ?


    as long as the laptop is turn off, there should not be a problem with you removing the battery. Is this what you have seen online?

  • turn laptop off
  • unplug cable from laptop
  • remove battery
  • press power button off (dries energy and resets system)
  • insert battery
  • plug power cord back on
  • This helps when trying to reset your computer and it also helps when you are trying to restore battery a little bit. I do not think, it would help you with touchpad buttons though. What you could try is taking laptop apart and resetting the actual touchpad button. From what you are saying, it is only stuck. You would have to take front cover of laptop to reset it. If you are not comfortable doing it, take it to a repair shop. Mostly this keys have some sort of plastic springs. When time passes this springs loose their springness and they get stuck. It is not that hard to try to fix. If you give me the model, I could probably find disassembly instructions for it.


    Acer Aspire 4810T battery wonít charge. Have bought a new battery, but it wonít charge either.


    Hello, did you buy an original battery from manufacturer or the cheap replacement ones? This can happen when a cheap replacement is used/bought. One of the ways of finding out if this is your case is to get a battery from original manufacturerís and see if it charges. Most times and if possible for you, return the battery and get a good quality one.
    Is the old/original battery dead? You could try finding somebody that has same brand and model laptop and try both your batteries there. Another possibility is for you to take the battery to a technician so that it can be tested with a multimeter and other tools to see if it has any charge.
    Does the laptop work when it is connected? If the laptop does not work even when plug in, I could say there is something wrong with the power supply.
    Cables and chargers can have something to do with it, especially if they are all chew up or there is insulation missing and/or cables are damaged. You could try using a different charger for it. That way you can see if it is the charger itself causing this. You could try resetting the laptop as follows:

  • unplug laptop from outlet
  • take battery off
  • press the power button for at least 30 seconds
  • insert battery
  • plug laptop to outlet
  • check the charging light or
  • start computer
  • check if icons in taskbar shows as charging
  • try doing this a couple of times
