    Hi there, I have a Dell Inspiron 6400 laptop and it is about 2 years old now. I have been taking the battery out when I can in the hope that it won't run out as quickly. However, I noticed the battery was only lasting about 1.5 hrs (depending on use) so I just left it in and now the icon in the taskbar says there is no battery detected, even when it is in. When I take the charger out, the battery continues to run but it still doesn't detect it and a continuous red light comes on the charging symbol. It lasts for a while and then just shuts down without warning when the battery runs out.

    So the battery is still working, I'm guessing it's still charging if it can still function but it says it's not detected by the computer? I'm confused on what is the problem is here - whether it's a dying battery or motherboard problem? If anyone could shed some light, it'd be appreciated!

    Thanks

    Does the computer indicate the state of charge in the battery in Control Panel> Power?

    When the battery is left on charge over night, how long does the laptop run on that charge?

    I'm on vista but the battery meter in the control panel doesn't show any battery charge, it's just greyed out

    The battery lasts for about an hour, maybe a bit less, after charging overnight

    Thanks
