Eliminating Battery Alert Message on HP Pavilion dv9770ew Laptop - Procedures?

Hello! When starting the HP Pavilion dv9770ew laptop, I get a message:
"HP Battery Alert
The system has detected that the capacity of the battery listed below is very low.
For optimal performance, replace the battery.
Primary (internal) battery (601)
ENTER - Continue system booting
For more information, please visit: www.hp.com \ go \ techcenter \ startup "

According to the description link performs a battery test but I do not know how to calibrate so that the message disappears.

Defective battery. If from bios, replace it and when it comes to the battery, buy a new one or use it on the power supply itself.

The solution on the HP website will bring a positive effect only if the battery is functional and has adequate capacity.
If not, it remains to replace the battery, remove and use only the power supply, you will get used to the message.
Batterymon can provide detailed information on the condition of the battery.
