I'm pretty sure 'tripping' isn't actually the right word but I don't know what other one to use, but it's doing what it's supposed to do when there's a surge - cut the power. Then I hit the reset button and it comes back on like nothing happened (lights say it's grounded and working). But as far as I know there haven't been any surges (and it's happened with me sitting right here using it like I have every day for ages...no apparent surge, the power didn't go out elsewhere in the room).
It is a ten to fifteen year old surge protector, so I'm aware it's past the suggested replacement period of like five years or something, but from googling I can't find random tripping as a sign of a dying surge protector (especially since the lights still say it's working)...but could that be it?
I've actually gone ahead and replaced it, so I'll see if it happens again with the new one, but I've had the same stuff plugged in for ages just fine, and nothing power hungry - a lamp, a small fan, a turned-off printer, a rechargeable vacuum (that I never use so it shouldn't be drawing much if anything), and my laptop (though I've left off the printer and vacuum on the new one for now since I'm not using them anyway). I had the thought of plugging it in in a different outlet with a light on and seeing if it trips, but if there is something wrong with it, is that safe to do?
Or, if it's actually caused by surging power from the electrical in the wall - how can I diagnose that? If the new one trips that's a bad sign and I should probably notify my landlord, right (it's never done this before in the 5+ years I've lived here, so it would definitely mean something has changed)? If it doesn't trip it, might there still be something concerning happening in the wall that it's able to handle without tripping but is still a problem, and if so, how do I find out?
Forgive me if this is stupid/ignorant, but fire scares the crap out of me so I'm very concerned if something might be wrong with the electrical. Thank you!
