The battery will run the computer but the ‘fuel gauge’ does not register or recognize anything. What is wrong?

Check if your battery is a ‘SMART’ battery, which will interface with the computer's software. Not all batteries have a 'SMART' option. If it has a fuel gauge, then it is probably a ‘SMART’ battery. Most new notebook computer batteries are ‘SMART’ which means that they have internal microprocessors that will allow the battery and the computer to communicate. If you establish that your battery is a ‘SMART’ battery and the fuel gauge does not work properly, then the battery may be faulty.
