My MacBook starts up with disk utility like there is no system
I upgraded this MacBook 5,1 with a Samsung SSD drive. I don’t use a lot, but recently when I turn it on, disk utility runs like there was no system. I quit the app, then choose Restart and it starts up normally. Old Mac computers used to have a small lithium battery. Some say it is a capacitor. Might this the problem?
specs
8GB ram
256 SSD Samsung drive
MacOs 10.11.6 El Capitan
Is this a good question?
