The Dell XPS 15 2-in-1 (9575) is one of our top convertible laptops in the 15-inch range right now as it brings a lot of punch with an excellent and fun design.

One of the challenges with it, however, is the dual Intel (CPU) and AMD (GPU) hybrid chipset aka the Intel Core i5-8305G or Core i7-8705G – it's never been done before. Any new chipset brings with it some growing pains and the Intel G-series is no different. One of those has been mediocre battery life and fans that can more frequently than expected.

Dell has already pushed out one firmware update for the 9575, and another one came out last week. BIOS version 1.1.5 is a step up from 1.1.1 and with it bring a few important fixes. In fact, Dell is labeling the update as "urgent" meaning you'll probably want to install it.

The main fix with 1.1.5 is fixing the fan noise when the 9575 is plugged in via AC. Indeed, the 9575 did have its fans whirring whenever you plugged in even if you set Dell's power-management software to "Quiet."

We've been using 1.1.5 over the weekend, and there is a massive difference now with the fans running when needed (which happens mostly during charging) and going completely silent when the laptop is fully charged. It's a night and day experience.

Owners of the XPS 15 2-in-1 (9575) can probably expect a few BIOS updates along with some driver refreshes for the video card over the coming months as the G-series chipset's software gets polished and optimized. Hopefully, that also means some battery optimization too.
