I have a Dell Inspiron 1000 running Windows XP. When I try to turn the laptop on with the battery in, it freezes at the Dell splash screen and will not respond to anything. However, when I take the battery out and turn it on using AC power, it works and boots perfectly normal. Windows shows the charging status as "Unknown Power Remaining". The charging light is green constantly. It nevers goes orange as it should when charging. Is it a problem with the battery or the computer? Again, the battery is what seems to make it freeze at the Dell screen. Once I take it out and try to boot it works fine.
