Why does my Aspire ES1-531 take a long time to power on when using battery power?
Some Acer Aspire ES1-531 systems may take longer than expected to start when using battery power. Installing the latest BIOS update can improve the boot time for ES1-531 models that have 500GB or 1TB hard drives.
Note: Systems with 32GB and 64GB SSD drives should not experience slower boot times.
