9-hour battery settings

It wasn’t as complicated as I thought. Here are the settings my friend uses to get 9-hours of battery power.

The trick, my friend says, is to set the CPU speed to the lowest.

Here’s how it’s done on my IBM T43:

a.) Left click the green battery meter beside the task bar
b.) From the menu, select “Launch Power Manager”
c.) In “Scheme Name”, click the “New” button.
d.) Key in a Scheme Name, e.g. “Maximize battery life”
e.) Under Battery settings, System settings:

Maximum CPU speed: Low
Optimize fan control to: Balance all parameters
Display brightness: Level 0 (Lowest)
Click Next

f.) Under Idle timers, Battery settings:

Lower display brightness: Never
Lower display refresh rate: Never
Turn off display: Never
Stop hard disk rotation: Never
Enter system standby: Never
Enter system hibernation: Never

The settings in step f are personal preferences. I think the real key is the CPU speed and the display brightness in step e.

I tried out the settings. It gave me 5 hours and 40 mins. Not as good as my friend’s 9 hours, but better than my normal 4 hours and 20 mins.

Let me try a full cycle of battery discharge and charge, let’s see if I reach the 9 hour mark.
