I now keep it as a home-computer only, plugged in all the time, and while I occasionally reboot it, mostly I just put it to sleep. It has stayed at 14% for the past month or so. I learned the trick of removing the battery, unplugging the power and holding the power button for 5 seconds to reset it, and that worked-it allowed the machine to boot up once everything was plugged in, and the battery charged up to about 14% (with a ‘battery charging’ icon), then it stopped charging. One day, the machine refused to reboot and I dragged it around on a two-week vacation without using it. Battery level is very low, battery icon shows plugged in but NOT charging. Bought a replacement (again on Amazon) and it worked for a few weeks, then exhibited the same symptoms. Last year, the battery seemed to fail I would regularly run it up and down from fully charged down to 15 percent or less, and it would always recover, but then it only recovered to 50 percent, then 25, and finally it only went up to about 4 percent. Still, it seemed to work fine for a couple of years (even though I just discovered it’s only 45 watts). The original A/C adapter failed (I thought) so I bought a replacement on Amazon, which showed as having the illuminated ring, but sadly it doesn’t.

Software which places less demand on the processor can also reduce power consumption in some cases,along with programs which use a dark-colored background. If the software utilizes memory more effectively (rather than reading/writing to the disk or hard drive frequently),it may use less power. Software: Different software which accomplishes the same functions may cause your Apple PowerBook G4 15inch battery computer to use different amounts of power.
Avoid leaving such devices plugged in longer than they need to be. USB Devices: If your Apple PowerBook G4 15inch laptop computer has a USB port,keep in mind that some USB devices draw power from the computer's battery while they are plugged in to it.

In some cases,upgrading the amount of memory will reduce hard drive usage. Because these are mechanical mechanisms,they consume more power.
Hard Drive & Disk Drive: Avoid using the hard drive and disk drive excessively. Screensavers with graphics and sound effects will drain the power more quickly,whereas a blank screen will conserve power.
Screensaver: Change your laptop's screensaver to a blank (Black) screen,and set it to turn on within a few minutes of inactivity. Here are some tips for making them last longer between charges. Laptop computer batteries often run out of power sooner than would be desired.
