Dell guides

Guides for Dell Latitude laptops and OptiPlex desktops, from Windows 11 checks to spec sheets.

Windows 10 & 11

  • Can my PC run Windows 11?

    Run Microsoft's free PC Health Check. PCs from 2018 on usually pass, and a TPM or Secure Boot failure can often be fixed in the BIOS.

    How-to · Updated
  • Can a 7th-gen Intel PC run Windows 11?

    Not officially, and no setting or processor swap changes that. Your options are ESU for now, Linux, a workaround, or replacing it.

Speed up & upgrade

  • Does my laptop have an M.2 slot?

    If Windows shows an NVMe drive, yes. Otherwise check the maker's spec sheet for your exact model, or open the cover.

    Quick answer · Published

Buy used

  • Are refurbished computers worth buying?

    Yes, if it's an off-lease business model from 2018 or later with an SSD, 8 to 16 GB of memory, and a warranty.

    Decision guide · Updated
  • How old is my computer?

    Check the processor in Settings, System, About. For the exact date, look up the serial number on the maker's site.
