Lily is a Dell Inspiron 15-3543.

Purchased in 2015, used as a workstation throughout high school and university, now a faithful companion and a daily driver. Its trackpad is clunky, keyboard sometimes gets stuck, battery is basically dead and has to be constantly connected to AC. The CD/DVD drive and the dead HDD have been replaced with SSDs. It currently dual boots 9front and Windows.

Specs for future reference:

Intel Core i7-5500U,
NVIDIA GeForce 840M,
1x8 GB DDR3L,
two 256 GB Samsung EVO 2.5″ SATA SSDs (850 and 870),
Intel Wireless-AC 7260 (previously Broadcom BCM43142) via mPCIe,
40 Wh Li-ion battery @ 14.8 V (type XCMRD),
PA-12 family 65 W AC adapter, 7.4 x 5.0 mm barrel, 19.5 V ⎓ 3.34 A.

1.1. Configuration

1.2. Wi-Fi

cp iwm-7260-17 /lib/firmware

After placing the file there, you need to rebuild and reinstall the kernel. This puts the firmware in the paqfs, allowing the kernel to see it before a root filesystem is mounted.

The driver works great, although it spams timeout errors on the console. It's best to set up some kind of /dev/kprint redirection.

1.3. Monitor settings (work in progress)

inspiron15=1366x768
	clock=76.32
	shb=1414 ehb=1446 ht=1610
	vrs=771 vre=776 vt=790

Data collected with xvidtune on OpenBSD.

echo actualsize 1366x768 > /dev/vgactl

1.4. Screen brightness

Control the brightness of the screen's backlight with Fn+F11 and Fn+F12.

1.5. Unresolved

/dev/battery returns all zeros. I managed to trace it to _BST returning garbage data. It works on Windows though? No idea what the problem might be.
