How can I enable system apps when the option to enable is greyed out?

My battery died and by the time I put it on, half my apps including system apps were gone. I was able to enable the apps which were downloaded from play store but the option to enable system apps is greyed-out. Please how can I enable it?

Welcome.

Unless Disabled by you, system apps ought not to need Enabling.

Charge fully, wipe the Cache Partition, and tell us what happens.

Note that routinely allowing the battery to discharge fully is generally regarded as bad practice.

Welcome to Android Central! Which phone? Which system apps are you referring to?

Did you install some apps on a SD card?
