Mine is getting older and slower, it won't run most newer programs, it crashes at least once a week, the battery is down to only lasting about an hour, the charging port has enough wiggle that it's probably going to start giving me trouble relatively soon, the hard drive is tiny, the RAM is over half in use even before I open any programs after restarting it, it regularly freezes up when doing such "difficult" tasks as opening Chrome or loading Facebook Marketplace listings, it doesn't have a number pad on the keyboard... I'm no stranger to using old computer hardware well beyond when most people would replace it, but there comes a time. I replaced my bottom of the barrel 2018 LG phone with a midrange 2021 Motorola a couple of years ago, my first computers were a Windows 98-era Dell running Windows XP and a Windows 3.1/MS-DOS IBM, and I still have a fleet of old computers.
Mine takes DDR3 RAM, which didn't go up as much because it's so old, but I'm not sure about spending that much on this one. It would probably be $40 to bump this one's RAM up to 16 GB. A bigger hard drive would probably run me another $20 or $30 because it's SATA, those aren't as desirable now, and I don't care about the extra speed of an SSD compared to an HDD. A new battery would probably be another $20, for an unbranded one that probably starts at 70% or 80% of its rated capacity. And then $80+ later I'm still stuck with a low end processor that was released in September of 2015 in a fairly low end laptop screen and body from 2016. According to the all-knowing AI that tried to convince me that memory prices have been declining the processor in that Marketplace laptop should be functionally four times faster than mine. Parts of mine's body plastics are also starting to fall apart. Half of the grille over the fan output has broken out and the plastic thing in the keyboard under the keys is coming apart. And that Marketplace one is supposed to have a backlit keyboard. I'm a night owl, so that would definitely be handy.
It should run it since he claims it has it installed, but other than for program compatibility I don't care about Windows 11. I'm still running a 2021 update version of Windows 10 Pro on my laptop and a 2021 or 2022 version of Android that apps are about to stop supporting on my phone.
The hard drive is a little small, but that's easy to rectify once the prices come down and other than that it seems like I wouldn't have much trouble getting another 5 or 10 years out of it given what I've gotten out of mine.
