I have a Dell laptop running Windows 7. When running on battery power, an alert pops up when the battery goes below 7% remaining battery life. Within 5 minutes of hitting 7% it goes into sleep mode. I understand my battery is having a problem and it does not last for even 1 minute after reaching 7% remaining battery life.
I want Windows to show an alert when it reaches 20% remaining battery life so that I will have enough time to plugin my laptop to AC power.
Can any body please tell me if it is possible to have Windows show a warning when battery reaches 20% battery life remaining?
