Best Buy support prices are ridiculous. Also if it’s his work computer, and we don’t know where op works, it might not be a good idea to go digging around. Op risks losing the data and we don’t know if its op’s computer that’s being referred to as a work computer or if it’s actual company property. If op can look at the connections on the side it’s possible they can purchase a monitor and connect it externally they’re going for about $110 at Best Buy

I know a lot of laptops have problems when it gets cold. I would suggest holding down the power button for about 10-30 seconds to discharge static build up.
