They clearly show wear.
I am not sure if they were replaced from another older device, or the entire cover is from L390, but that one would have a plastic cover for where this one has a stylus. It doesn't seem like anything was snapped out of there.

I couldn't find replacement ones online, and I am not sure if contacting the shop is a good idea. See, the L390 Yoga has a touchscreen with better colors and seems to be a bit more expensive (but not much).
However, I bought this as "L390". I noticed the description said "Touchscreen: yes", which I realized meant they likely mistook the Yoga version for the base version. Indeed, that is the case.
Currently they have one L390 Yoga in similar condition and same configuration, but the screen has some white spots (this one is flawless), ...and it's €46 more expensive.

If you're curious, i5 8365U, 16GB RAM (single-channel), used 256GB Samsung SSD (I don't remember if SATA or NVME), €180 and 2 year warranty.

Also, if you're wondering what that port with network symbol is, it appears to be a proprietary connector used on ThinkPads requiring an "Ethernet Extension" adapter to be usable.

Probably dust particles and slight rotation while in the backpack.

Just from "a quick query" by the admin.

there'll be a better one later, this is just a quick query

So, last Sunday I suddenly got high-pitched tinnitus, mostly in my left ear. I thought it would be gone when I wake up next day, but it was still there. Then on Tuesday and Wednesday I had some pain and pressure in both ears. Unfortunately, I'd need to get referred to ENT by my GP, and she was on vacation. The substitute was there for "acute cases only".

So far this was just... quite annoying. I tested for possible changes I haven't noticed with frequency generator on my phone. With medium volume, both ears went to 19.5kHz just fine.

Thursday it improved. Or so I thought. The tinnitus got quieter. Later during the day I went to check again. I started with 16kHz at lowest volume. Suddenly, I could only hear it on my right ear, so I started panicking.
Left ear fell from 19.5kHz to 15.5kHz in just 1 day. This was a fairly sudden change, and I am not exactly emotionally strong. I panicked and was crying and hyperventilating for about an hour.

So I decided I'll go to the substitute doctor next day to get referred to ENT. I set up alarm for the morning, but I didn't need it. I was too anxious too sleep much anyway.

So I got to the ENT right that day.

She visually inspected my ears and throat finding no signs of inflammation. Tympanometry OK. Audiogram just confirmed my feeling of right ear being muffled with slight low frequency hearing loss, but nothing for my left ear, primary source of my concern.
I explained the loss occurred in higher frequencies than I heard during the test. I asked what frequency they tested up to as it sounded fairly low. "6kHz." Apparently, even 8kHz (worldwide standard) is considered "experimental" in my country... I hoped for possibility of EHF audiometry (9 - 20kHz).

Back to talking with ENT, I said that I could hear up to 19.5kHz on both ears ereyesterday, yet yesterday I couldn't even hear 16kHz on my left ear. She re-assured me that we normally loose ability to hear these frequencies with age (I am 18).
I further explained that my concern is rather the sudden unilateral loss as opposed to gradual bilateral loss over longer timespan as it could continue worsening further.

She replied with "Hearing above 6kHz is not important to humans." I wanted to tell her to resample all her music to 12kHz, then tell me how useless it was, but I didn't want to be rude.
At last, I asked "What about the tinnitus?" with response being "Nothing."

So, she just prescribed me vitamins B1, B12 and some Ginko extract pills for increasing blood flow to ears for 1 month which I still had to pay €30 for even with insurance.

Welp, I just apologized for bothering them (non-sarcastically) as they had more patients and left no less concerned.

I am pretty worried about this. I've been careful with my ears. I don't listen to music loudly, I don't go to concerts, hell, I didn't even have to go to theatre with school the last time as my current class teacher noticed I wasn't exactly OK with being in a room with lots of people, especially with loud noise.

I can only suspect some issue with inner ear, perhaps inflammation. That wouldn't even be noticeable with just visual examination. However, I suppose that would also be accompanied by dizziness and vertigo.
So I have no idea what's going on.

At least I distracted myself while typing this.

"at least"

Image on left is from 4 days ago, but the pimple was slowly forming over around 2 weeks.

The goop was sticky, not oily. Earphones are Panasonic RP-TCM130.

I was not able to find an explanation.
Something to increase cable lifespan, lubrication, rubber disintegrating, sweat and earwax that somehow got into the cable, dielectric grease, SCP-1407, no clear answer.

At first I thought the wires just somehow twisted. Nope.

I used to think that age equated to percentage of life lived, thus I thought that most people live to close around 100.
But it also made me think that people only get old when they're like 80.

I mean like actually "old". The "old" adults were referring to. At that age I considered those 14/15 year old 9th graders old, just a bit different "old".

For some reason this happens to me, but only with Orbit. At least the watermelon ones (I prefer chewing gums that leave minimum taste), I don't know about others. It just turns into a disgusting paste.

Laying on his back, if the perspective seems confusing.

OK, I hope my question doesn't get misunderstood, I can see how that could happen.
Just a product of overthinking.

Idea is that we can live fairly easily even with some diseases/disorders which could be-life threatening. Many of these are hereditary.
Since modern medicine increases our survival capabilities, the "weaker" individuals can also survive and have offsprings that could potentially inherit these weaknesses, and as this continues it could perhaps leave nearly all people suffering from such conditions further into future.

Does that sound like a realistic scenario? (Assuming we don't destroy ourselves along with the environment first...)

This battery lasts the life of the router under the operating environmental conditions specified for the router, and is not field-replaceable.

But who determines its lifespan?

Knowing there is a battery set to fail and I can't simply replace it makes me physically uncomfortable. Enough so that I'd rather it not have RTC.

Thanks Cisco.

Sorry for the lazy meme, I don't know what else to make this branch diagram in.
