From your ref: "[...]and if it does so in time [...]"
...Which it won't... I fix em for a living, and live in a place where brown power and surges are plentiful - Simply attaching a UPS will extend the life of a machine by a lot here - especially out of town, and very especially off-grid... And I get them all the time across my bench and into the scrap pile when they ain't (att'd/UPS).
Laptops do better, because the in-built battery does the same thing a UPS does - It's a slush-bucket that absorbs browns and surges - At least to a degree.
I’m on a laptop. Have been for years.
My power is very flakey.
No problems (yet!)
