Laptop Battery drains insanely Fast!

Thu Feb 12 15:36:45 UTC 2015

Ok. I will try to write them more clear [?]

My $ *sudo kldstat -v | grep ibm*

 2    1 0xffffffff81956000 7808     acpi_ibm.ko (/boot/kernel/acpi_ibm.ko)
         1 acpi/acpi_ibm

PS: My battery still dropping too fast. The last five minutes dropped from
37% to 33% and is just open doing nothing!
