MCE errors on processor cores on boot. New Laptop

Hello,

I am getting mce check errors on boot four all four processor cores on my new dell inspiron 15 7000 gaming laptop. I don't have the exact content of the errors as I don't know where the log file is. Also an acpi error that occurs later. My best lead so far was to update with the intel-ucode package which I believe I did successfully, but I still get the errors. Any ideas on where to start?

Edit: Sorry I was trying journalctl -b which did not show the errors, but I've found them with a regular journalctl:

Feb 04 10:37:45 laptop kernel: ACPI Error: [\_SB_.PCI0.XHC_.RHUB.HS11] Namespace lookup failure, AE_NOT_FOUND (20170728/dswload-210)
Feb 04 10:37:45 laptop kernel: ACPI Exception: AE_NOT_FOUND, During name lookup/catalog (20170728/psobject-252)
Feb 04 10:37:45 laptop kernel: ACPI Exception: AE_NOT_FOUND, (SSDT:xh_OEMBD) while loading table (20170728/tbxfload-228)
Feb 04 10:37:45 laptop kernel: ACPI Error: 1 table load failures, 10 successful (20170728/tbxfload-246)

and,

Re: MCE errors on processor cores on boot. New Laptop

The ACPI errors are normal, the other errors might indeed be due to incorrect microcode, however, why do you "believe" it to have been done correctly? The wiki provides a way to check. If you are still unsure, post an entire untruncated dmesg/journalctl.

Edit: If a journalctl -b didn't show them anymore, that would also be an indication that whatever resulted in these errors, doesn't result in them anymore. If you run "regular" journalctl you will see the complete history of all the logs, which will include past ones that might've shown an error (due to lack of microcode) that aren't an issue anymore.

It still displays the errors on every boot. That is why I think it's persisting. I said I believe it was done correctly because I did it a while ago and don't remember the specifics. I will further consult the wiki and make sure.
