Hi Jason, Sorry, no solution, bit to avoid in the future suggest you invest in a UPS (Uninterruptible Power Supply). Also, do you have a surge protected on your mains supply.
Personally I use APC units, these can serve both functions above and can also filter the Ethernet/phone line for lightening strikes. https://www.apc.com/uk/en/ <https://www.apc.com/uk/en/> Perhaps your Uni would buy it for you. I’m not really paranoid. Good luck.
