Copying and pasting from another comment i made, hope this helps:
There's basically three things you need to do to survive.
1. (and most important) Keep an eye on the panel in front of the doll in the laboratory, in the room in front of you from the office, take a left and you'll see a panel glowing either green, yellow or red. Make sure to keep that panel from going red by just interacting with it.
2. When the circuit breaker flips, you have to run to the IT office to flip it back up. Implying you're coming from the showroom (Room in front of the office.) head out the back left door and then follow the hallway until you reach the room just after the locked love room. the switch will be in between all of the servers, and just across from where the MQ Blue startup computer is.
3. Speaking of the MQ, It's basically the same, however, when the MQ Startup begins, run to your office and grab one of the flashdrive that's to the right of your computer screens, Then, Run back to the IT office and insert the drive into the MQ screen that has the skull on it.
