    PS4 loses date/time settings every time

    Good day folks. Pretty difficult problem here and I was hoping those more knowledgeable with consoles can provide some input, since the internet was of no help and I couldn't find this issue anywhere else, plus I haven't exactly messed around with PSs before: I've got this PS4 (slim?) here which can't hold on to its date and time settings. It loses them as soon as you remove mains power, like a cheap digital clock when it's unplugged. If you leave it plugged in, everything's fine. Checked and replaced the CMOS battery inside - no luck. Measured the resistor+diode assembly that follows directly in series with the battery, but that was as far as my knowledge got me there. It all looks good - battery voltage makes it into the board. The board says SAE-004 on it.

    I took some pics as well, but haven't got a cable to upload them right now A colleague of mine also suggested the SPI chip might be bad. We managed to identify it, it's a 25Q256, but it's a flat SMD package and we don't quite have what it's needed to read/write it....plus I'm not sure we'd have something TO write to it in the first place, unless we could get away with copy/pasting the contents of the existing chip onto the new one in hopes the current one has got bad blocks. I think what's happening is the date/time is stored in some sort of flash memory when power is available and when mains power is removed, it's supposed to get stored somewhere, but this is not happening for some reason. Interestingly, the time ZONE settings remains intact to what you set it to - presumably it's stored in some other place and it's only the RTC part that's busted in some way. Any ideas ? Thank you.

    did you check that the power from the battery reached the chip?

      No, must admit I haven't done that. I didn't quite get to mess around with it at my own pace - my colleague did most of the work, but now that I think about it, what you suggested makes perfect sense. I'm guessing I should see battery voltage at the VCC pin of the Flash SPI.

        um, no.
        why would you have battery power at the flash?
        the clock is in the main chipset.
        it will go to a big bga chip - a givaway is it usually has a 32.768Khz crystal.

          My bad...
          This might mean the bug lies in a much "bigger" component after all...

            the timezone etc is stored in the o.s.
            the callender, clock and some extra cmos ram are integrated into the chipset itself.
            i'v seen this with a few industrial motherboards that are used in contaminated enviroments and it's always been a corroded track, via or small part like a resistor or capacitor.
            just follow the track from the battery till it reaches the chip with your meter set to ohms/buzzer

            btw, if you set the time, and when you power up again, it's not reset but shows the time you put in then suspect the crystal or it's capacitors.

              Yes, if I leave it plugged in and reboot, the time is still corect.

              There's also some other issues with this console: one of the USB ports is not working and it's also got some issues connecting to PSN - some error code shows up every time despite setting the correct date/time.

                then check the usb port tracks too - there maybe be damage in a common spot.

                  Re: PS4 loses date/time settings every time

                  G, my much older colleague who's been in the Sony business for years now, already looked into the USB issue some time before while I was there. He thought he found an open inductor in series with two of the data lines for that port (the tracks were clearly visible), but even after replacing it with jumper wires, the port still didn't work, so the problem is in the controller chip and possibly also related to the date/time issue and PSN error as well. I think I'll volunteer to have a look at it myself on my own. Trouble is I need to make sure I don't make it worse

                    Re: PS4 loses date/time settings every time

                    does it use a standard chipset?
                    i'v not looked at one.
                    just thinking on datasheet availability.

                      Re: PS4 loses date/time settings every time

                      I don't have it in front of me right now, so I don't know what the chip was (the one to which the traces for that dead USB run). I couldn't find any high-res pics of a SAE004, so this was the best I could do (the part circled in red). THIS video show a similar problem, but for a different board, so the chip here is a GL3520.

                      Trouble is not even Sony provides any sort of info on its assist platform for ANY, repeat, ANY ! of the PSs currently on the market, so we're pretty much stuck and at the mercy of the internet and other folks who might know more about these things. I'm not sure how they expect service centers to work on these things if they don't provide even the most basic of info on them.....

                        the GL chips are shity usb hub chips,
                        you see them in £-land / $-store hubs!!

                          They don't provide it but there are service manuals for the, PSP, PS1, PS2 and PS3, so there's probably one for the PS4 somewhere.
                          Sony don't make any money if their stuff is fixed by a third party so there is no incentive to release anything.

                            That's just it: we ARE an "authorized" Sony center, hence why we have access to the support platform and hence why there should be material available to work with for us techies I can fully understand not making anything publicly available....actually no schematics or resources are SUPPOSED to be publicly available anyway, but they eventually "leak" onto the internet.

                                Support platform ? And authorised to do what, I very much doubt they want anything other than boards/whole assemblies swapped when under warranty and out of warranty they get no money and possibly their name damaged by poor quality repairs, hence no schematics are supplied.

                                  I don't know how you'd call it exactly : it's a sub-domain of Sony where partners like us receive a username and password to log in and get access to schematics, diagrams and what they call "technical bulletins", which are quick solutions to specific known issues with certain products, such as "No power = replace this part" to speed up the repair process. Not all models have schematics though - some have no resources at all, or they're very brief and useless, mostly listing part numbers.

                                  True, a more appropriate description would be a Sony "warranty center", where all products under warranty end up. Unless Sony posts a technical bulletin for a specific issue and instruct you to replace a specific component, the only solution is to replace the whole board, as you pointed out. No need to waste time trying to fix it at component level, plus they would no longer accept it back if you've done anything to it and you end up having to pay for it yourself ! That's not to say you can't hop on that assist website for schematics and other stuff for out of warranty products as well, but like I said: they're not THAT helpful sometimes....just a bunch of part numbers most of the times, though other times I WAS able to find stuff which wasn't available anywhere else, or at least not for free. Trouble is I get a watermark with our username all over the PDFs, so if anyone needs anything, I'd have to send them privately which I did a couple of times so far.

                                    Ahh, Partner Portal (their speak), I knew what you were referring to, I was interested in what they supplied apart from service bulletins.
                                    Some but not too much in case they give away any secret sauce.

                                    I don't suppose there's anything on their SRS-X55 speaker, in particular I need to identify the 8 pin IC that takes input from the DC jack. I have one and it's burnt up. A long shot, but worth an ask.

                                      Unfortunately no - nothing of use there. Just two pages with part numbers for the adapter and junk. Same goes for any PSs: NO resources AT ALL - not even an exploded view or something. I have no idea why this is. Naturally, when people see a big SONY logo on your building AND learn you're an "authorised" repair center (I keep putting that in quotes because I find it sounds stupid ), they'll bring in their out of warranty Sony products like PSs and Vaio's and expect them to be fixed without a question....which half the time is not possible due to the lack of resources. This often leads to harsh reviews and criticism from customers because they believe we ARE Sony, yet were unable to fix their problems - "how is this possible ?!" By contrast, an independent shop like the one I used to work in, which was not related to any brand (though we were planning on making a move on Samsung at one point, which never happened) can get away with simply saying that they could not fix something and that is that - end of story.

                                        Thanks for looking, I guess the upside of having a big Sony sign is it gives some credibility to the business and it brings in other work.

                                          Asus BIOS How To Reset To Default Settings?
                                          by YG007
                                          Hello... Where do I start. I have 2 questions/scenarios that might bring this laptop back to life, so here it goes!

                                          I have this laptop (Asus UX52VS) where I was flashing the BIOS to it and it froze during the process. I didn't have a reliable BIOS chip programmer at the time (It was a CH341A USB Programmer from Amazon where it took hours just to get the clamp on the chip and then every time I read, it gave me different results/corruption, and never would pass the verify test as no 2 reads were the same data), so I brought it to a shop. They had it for almost 2 months, but during...

                                          Gaming Laptop Zephyrus S17 TFT not detected every time !

                                          Hi guys,
                                          I post my problem here because I think it could be a capacitor related issue (Asus support on this particular subject is non-existing).
                                          So the computer is a Zephyrus-S17-GX735LXS-26T and the strange behavior is seen.
                                          On cold start most of the time the internal screen is detected and a picture it works fine until shutdown, sleep or deep sleep.
                                          Then the screen won't work for a long period of time.
                                          If I wait 1 or 2 hours it work again most of the time.
                                          When it doesn't work the batterie indicator blink 3 times white stop and the same schematic is repeated...

                                          Elitebook 820 G3 engineering example: CMOS settings lost despite new cell
                                          by i440bx
                                          Hey there,

                                          I got a HP Elitebook 820 G3 Engineering Sample Laptop and I want to use it. Besides the difficult things at the ES-BIOS I have a big problem by saving the main BIOS settings.

                                          The laptop does not have a big battery because it was dead, but I already plugged in a new CMOS battery.

                                          It takes about 5min without power and the BIOS settings are lost. Unfortunatly I dont understand why the BIOS settings are only saved with power connected and this is the reason why I registered here.

                                          As written above, I plugged in a new CMOS cell and checked...

                                          Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.

                                          I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For...

                                          Adding a clock battery to action camera to retain date&time when changing batteries Campark X25
                                          by flat-earther
                                          I have a cheap action camera with an annoying trait, every time I change batteries the date & time gets reset and I have to set it again.

                                          To solve this problem I want to add a small internal battery inside it which will keep supplying power to the camera for a while while I change batteries so the date & time is retained.

                                          I have opened the camera and I think there is enough room to add something inside to accomplish this:

                                          The camera is powered by a 3.7V nominal single cell lithium ion battery.
                                          So I need to connect another battery in...
