Do we know the screen brightness level in nits. I cannot find more info on screem beyond 1080p.
Genuine question, what do everyone do a year ago before arbitrary "nits" ratings became a buzzword? Reminds me of contrasts radios, something that ever single company rated different and rarely made a difference in blind testing.
Not to mention who runs their laptop screen in full brightness.

Nits as a term have been around far longer than a year. I cannot speak on where you first heard it but it has been used to help gauge screen quality for tvs,monitors, and other display applications for years as the resolution quality stopped massively increasing and a wide range of high and low quality displays entered the market. Generally 250 is considered somewhat low for a modern display with 300 being normal and 400+being on the upper end.

I realize the term is much older than that. People complaining about it on SD like they could tell the difference on a 'blind taste test,' not so much.

Like contrast ratios? Yes, they started out a great idea until every manufacturer invented their own test. Somehow TV's went from 5,000:1 contrasts ratios to 5,000,000:1 in only a few years. 'nits' hasn't devolved that much but is on the way.

Considered by whom and by what objective test? That is really my point. Unless the ratings are standardized and performed under identical conditions the number is beyond meaningless. Even if some independent 3rd party was certifying monitors the maximum brightness is not very important unless you will be running the screen at max illumination. Especially considering you will not be running the screen at full brightness unless you are typing away under the noon sun. Not to mention just because it can achieve a certain brightness...doesn't mean it will look decent at that brightness. Again, something that arbitrary "nits" number does not take into consideration.

So yes, the number is meaningless.
There are a number of circumstances under which I run my laptop on full brightness. A lot of this DOES have to do with working outside so this would be a relevant spec to be aware of. Not sure it's fair to say the number is meaningless.

Lets pretend you do run the laptop on full brightness...we'll stop talking about that.
The number is still meaningless because: -There is no standard of testing between laptops or manufacturers. HP and Dell could test each others laptops and come up with WILDLY different results because their testing methodologies are completely different. So the # is meaningless unless you are comparing two laptops from the same manufacturer that were tested (in theory) using the same testing procedure.
-Brightness can effect screen quality: just because a screen can achieve a certain brightness does not mean it is as usable as another monitor's "less nits" brightness. We've all had phones or laptops that were basically unreadable in the sun. "Brightness" is rarely the reason. Look at any e-reader's screen, brightness is never a factor in useability..especially in sunlight. Crazy right?
Imagine if car two car manufacturers rated their average miles per gallon with different conditions:
Car manufacturer A: tests car with just the driver and 1/3 of a tank of gas and no cargo (less weight)
Car manufacturer B: tests car with a full load of passengers, full tank of gas, and 1000lbs of cargo.
Would those numbers be comparable? of course not. That is now this silly "nits" rating works. Could be useful if done correctly...but isn't useful because it is not correctly and evenly tested.
So without standardized testing and context the number is a meaningless as a flat screen's TV's 5,000,000-to-1 contrast ratio.

Looks like a pretty good deal. Anyone here know how well this compares (in terms of build quality and reliability) to similarly priced Dells, Lenovos and HPs?
I've scoured the internet for a product manual, or *any* information on if the RAM on this is upgradeable. I've come up with nothing.
It seems the 16GB may be soldered - which is OK with me, but is there an expansion slot available?
Also, did anyone answer the brightness question on this?

Re: RAM. That's my understanding with the expandable slot. My BIL upgraded his model from 8GB to 16GB without issue.
So, do you know what the meaningless nits rating is?
The nits police haven't told us yet. Perhaps they have moved on to a new useless spec that has very little real world application and is measured differently by every single manufacturer and even their ratings change by the day. Years ago it was processer speed, ram speed, monitor refresh rate, DPI, perhaps next week it will be color temperature or maybe even specific gravity
Re: RAM. That's my understanding with the expandable slot. My BIL upgraded his model from 8GB to 16GB without issue.
What exact model did they have? The one on sale that this thread is discussing, A515-58MT-52RG, or some other similar Acer model?
Like the other poster indicated there is practically no detailed information to indicate if the RAM is soldered or slots. If slots or a hybrid of soldered and single slot, the question is what is the max upgrade the A515-58MT-52RG is capable of supporting? 16? 20? 32? The Acer website product page[acer.com] only states: "Total Installed System Memory 16 GB". That can be interpreted a couple of ways.

This video seems to confirm you can upgrade the RAM no? I think the page says 32GB total and it shows open slot at 4:55?

If there was standardization of testing AND took into account how washed out a screen became at full brightness it could be a very useful number.
It seems the 16GB may be soldered - which is OK with me, but is there an expansion slot available?
Also, did anyone answer the brightness question on this?

Edit: some comments say RAM is now soldered so the plot thickens…
Edit 2: this video review claims it's RAM upgradable up to 32GB.
