• Around the front edge where the aluminium bottom and the carbon fibre effect join there is a slight misalignment and it running your finger down the side it catches the aluminium slighty.
• Slight light bleed where the trackpad light is on the side where the glue holding the 2 parts together is coming away.
• The delete key is also stuck down so doesn't press in properly.
• Gap between the panel and the bezel, making the backlight bleed. Sometimes it seems not properly sealed.
• Crackle/popping sound from the internal speakers.
• CPU throttling.
Unidentified issues:


• Coil Whine while on AC power. This squeaking noise is most pronounced while cold booting the computer, and is less audible on battery power.
• Fan while charging: While charging the battery and until it reaches around 90%, the fans run at high speed that is very audible. I do not have express charge enabled in BIOS or Dell Power Command, and have optimal as the fan setting. This has been reported by other, but not all, XPS 15 owners
• USB-C Powershare: it does not charge when the laptop is off as when using the type-A USB ports. Powershare is enabled in the BIOS, and the phone does charges after logging into Windows. The latest Dell Thunderbolt 3 firmware was installed with no resolution.


General recommendations:

• Install latest BIOS update from the DELL site.
• If you don't use 32GB SSD cache drive or RAID, switch drive mode from RAID to AHCI in BIOS. [This will fix the issue number 5]
• If you don't use 32GB SSD cache drive or RAID, remove the Intel Rapid Storage Technology in Control Panel andinstall only AHCI drivers: 1) download latest Intel Rapid Storage Technology in a "f6flpy-x64.zip" variant 2) Extract the .zip package 3) Using system Device Manager manually update AHCI drivers only (iaAHCIC.inf and iaahcic.cat) under IDE ATA/ATAPI Controllers in the Device Manager. [This will fix the issue number 6 and 7]
• Don't install any DELL applications.
• Look for the latest drivers on each manufacturer site (nVidia, Realtek, Intel, etc) instead of the DELL site.
• Perform a clean Windows installation, don't use pre-installed DELL recovery systems as it contains old drivers and all sort of DELL bloatware.
• Keep your OS up to date with the latest system updates.
