I have never noticed it on any of my laptops, but if it is fine, I am happy 
with it, just I thought my aftermarket battery might be bad. Also as I pasted 
on of my /proc/ files

present:                 yes
design capacity:         18850 mWh
last full capacity:      18850 mWh
battery technology:      non-rechargeable

, it says this battery is not-rechargable. What is that mean? Is that a bug in 
ACPI or my battery is malfunctioning?
