Earlier Warnings of Low Batteries
Question : Is there a way to make my ThinkPad laptop alert me earlier that it's
running out of battery power before it turns off completely?
Answer : If you don't have enough time to dig up your power cord
before the screen goes black in the middle of your work, Windows XP gives you
the option to adjust the amount of time you get between that first warning of
low battery power and when it shuts down because of lack of power.
Go to the Start menu to the Control Panel area. Click the "Performance and
Maintenance" link (if you have the PC set to Category view) and double-click
on the Power Options icon. Click on the Alarms tab in the box. Make sure the
boxes are checked to activate alarms in both the "Low battery alarm" and
"Critical battery alarm" areas.
Nudge the on-screen sliders in both boxes to the right to increase the
amount of battery power you still have when the alert box pops up. For
example, you can have the "Low battery" message pop on when you still have 15
percent of your power cell left, and set the second, more serious "Critical
battery" alert to come on when you have 5 percent of your power left. Clicking
the "Alarm Action" button for each warning lets you add additional
instructions, like have the computer warn you with an audio alert.
