I work as head of IT in a medium sized industrial facility with about 300 PC’s and an equal number of other devices. I don’t typically do hardware support myself because we have part-time techs for that but I have to keep a very large cabinet of replacement parts including power supplies for every model of computer in the building as well as monitors, keyboards, mice and lots of other misc parts.
If you ask, does X fail, the answer is always yes because they all can and do. I have seen every type of failure imaginable. The most common things people ask when that happens is “What did I do to cause it?” and “Will I get in trouble for it?”. The answer to those questions is “Probably nothing because electronics just break often for no apparent reason” and “You won’t be in trouble because I don’t report routine failures to anyone let alone your boss unless you tried to clean it in the dishwasher or something.”
Individual computers and their parts are usually fairly reliable for a few years but there is a big spike in failures for new ones followed by a generally stable curve that starts to rise slowly as time goes by but any component can fail at any time with no obvious cause. I am glad you got yours straightened out. It will probably happen again several times in your lifetime.
On the other hand, I have rescued electronics by cleaning it in the dishwasher.
A friend’s girlfriend managed to spill a large cup of Starbucks coffee on her Macintosh laptop. This was before Steve Jobs went completely insane, and Apple devices still had removable batteries, so she had the presence of mind to pull the battery to minimize the damage.
I took the whole thing apart and washed all the case components and the motherboard in a dishwasher. I did not wash the display or hard drive. After that, I made sure all the components on the motherboard were fully dry with compressed air and a heat gun.
After that, I re-assembled it, and it worked perfectly for many years after.
Printed circuit boards are routinely washed in industrial dishwashers after wave soldering to remove rosin. We used to use trichloroethane, a liquid that has since been banned.
Not sure if this is the same thing, but I have a Lenovo ThinkPad that will neither accept a charge, or a battery from another unit. I think it just went toes up.
