Hi all, I was seeing ~9W power consumption when idle. It’s too much, I’d expect around 3W or so. With lid closed, laptop enters sleep mode (I believe), but stays warm and it has depleted full charge in about 6 hours.
OS: Debian Sid
In dmesg there are those lines:
i915 0000:00:02.0: firmware: failed to load i915/adlp_dmc_ver2_14.bin (-2)i915 0000:00:02.0: [drm] Failed to load DMC firmware i915/adlp_dmc_ver2_14.bin. Disabling runtime power management. ... i915 0000:00:02.0: firmware: failed to load i915/adlp_guc_69.0.3.bin (-2)
Which means that GPU’s firmware that does power management isn’t loaded. I’ve downloaded those files from here i915 - kernel/git/firmware/linux-firmware.git - Repository of firmware blobs for use with the Linux kernel and put them in
/lib/firmware/i915, and run
Now with those firmware blobs loaded power consumption is ~3.5W idle which is about right. But both Firefox and Chrome are unbearably laggy, and when browsing and scrolling pages around, CPU fan spins up to the max.
I’ve also tried booting Ubuntu 22.04 from a flash drive, and while I wasn’t measuring battery drain, it showed time on battery to be ~3h with about 40% of charge which indicates the same problem.
There are similar reports for Windows – Chrome being super laggy, and the proposed solution is to install latest intel drivers.
Any ideas or hints?
