I guess that when it comes to buying refurbished products in general, the old adage of "You pays your money and you takes your chances" usually uttered in connection with county fair midway games applies here as well.First, the good news...Although somewhat dated, this is an excellent PC and actually serves my particular purposes beyond my expectations. It is quick to load, blazingly fast, and doesn't skip a beat...do doubt due to the relatively high clock speed of 3.2 GHz as well as the unusually large 32 GB of RAM. I use it mainly for emails, surfing the web, social media, managing work requirements with Microsoft Office programs, and watching streaming media and YouTube videos, and it works just fine for all those uses. That said, not being a gamer I can't comment on how well it would perform to those more exacting standards, so I'll leave it to others here to elaborate on that.Now for the bad news:Perhaps the vendor's definition of "refurbished" differs from mine, and although the PC arrived exhibiting a like-new exterior appearance, the minute I plugged it in and tried to turn it on I immediately realized that something was amiss. All I got was a flashing amber light emanating from the "on/off" button and it refused to boot up. I then did some fiddling around with it and by trial-and-error discovered that if I unplugged the PC completely, plugged it back in again and then pressed the "on/off" button, it would boot up the way it was supposed to.My initial thoughts were that this might be a software glitch preventing Windows 10 from operating properly to initiate the boot up process, but various software "repair" options that I tried did not do the trick. I then called upon my friends Google and YouTube to try to help me discover the root cause, hoping against hope that I could sort this problem out by myself rather than having to invoke the "nuclear option" of wiping the computer clean of all the programs that I had already installed on it by that point, and doing a factory reset before returning it to the vendor for a replacement unit.Turns out that a flashing amber "on/off" button light with certain Dell products can have numerous separate and distinct root causes, and I spent waaaay too much time going down various rabbit holes to try to track this down. Some of the suggested diagnostics and fixes were quite complex and involved, and not being a total computer geek I did not trust myself to pursuing any of these for fear of getting in over my head. Other suggested fixes were more basic, and a lot of them pointed to a dead CMOS "button battery" on the motherboard being the most obvious - and often initially overlooked - culprit.I decided to try that suggestion, opened up the case, found the battery, extracted it and tested the voltage, only to find that it was down to 0.1V instead of the normal 3V...i.e. it was essentially dead. That was my "Aha! moment...or so I thought, but it also led to two other troubling findings. Not only did I discover that this computer was actually built in 2015 (i.e. 7 years old at this point, and older than I expected), but the brand stamped on the button battery was "Mitsubishi". Clearly this was the factory original, as I have never seen this brand of battery sold here for consumer use. So much for "factory tested" and "fully refurbished to original factory specifications" and a purported claim of "80% battery capacity relative to new".Alas, my joy was short-lived, and this simple "fix" turned out to be too good to be true. Much to my dismay, the original problem persisted, and the only way to boot up this computer remained the equivalent of jump-starting a vehicle each time before driving it. Not a viable option...At that point I decided to throw in the towel and contacted Amazon to arrange a return of this PC. In all fairness to the associated third-party Amazon partner and vendor, this turned out to be far less of a hassle than I had anticipated. I obtained my refund as soon as they received my return - no questions asked - and a replacement unit with the exact same specifications arrived at my home two days later. And bonus - the price of the PC had actually dropped by $10 in the interim, so there's that as well. Best of all, this replacement PC had none of the flaws experienced with the first one and performs just as I expected...and as I said above, maybe even better.In summary, my overall rating here averaged out at a "3". A "5" rating for the outstanding performance of this PC (when it works), and also the responsiveness of the vendor in immediately making this right without any of the expected "run-around" that often accompanies a situation such as this. But as for the experience with the first PC, sadly I can't give that more than a "1". It should never have been allowed to leave the vendor's premises without having been thoroughly tested and as a result, arriving at my home in the state that it did. It caused me to waste far too much of my own time trying unsuccessfully to diagnose the built-in problem, when starting up this computer straight out of the box should really have been a slam-dunk.
