I just ran into this issue. It is in fact maybe a motherboard issue. Note if your out of warranty they your best bet is to do it yourself if your tech savvy.First I recommend to replace the CMOS battery which you can get one from a rite aid etc. Now bare in mind that once you replace the battery and you go through all the steps below this paragraph, then later the information is lost a again meaning you get that serial error then you can determined that the motherboard is really bad.Second copy down the:S/N: maybe on sticker at bottomP/N: maybe on sticker at bottomModel# maybe on sticker at bottomPCID which is located under the battery via white stickerNext what you want to do is to re-write these to the bios. Go to the page below and download the Rufus software to create a bootable USB drive. Also you will need to download the file 'HP DMI'All the links to these files can be found here: and there is a readable instructions on what to do but I recommend using the you tube video link once you have prepared the USB.Once you have prepared the USB, go to the you tube link belowand follow this step by step via the YouTube video link below.
