n 183 N Troubleshooting Battery How do I find the battery charging status? See Charging the Battery Pack (page 31). When is my computer using AC power? When your computer is directly connected to the AC adapter, it uses AC power, even if the battery pack is installed. When should I recharge the battery pack? ❑ When the battery level falls below 10 percent. ❑ When both the battery and power indicators blink. ❑ When you have not used the battery pack for a long period of time. When should I replace the battery pack? If the battery power is still low after charging it, the battery pack may be reaching the end of its life and should be replaced. Should I be concerned that the installed battery pack is warm? No, it is normal for the battery pack to be warm when it is powering your computer.
