Problems with CPU throttling on HP 15-n066us laptop
Hello, I purchased a new laptop for FreeBSD and am having some problems with CPU throttling. This laptop has an aMD a10-5745m processor. I cannot start powerd and the frequency levels in dev.cpu are absent. I tried with 11 and when that didn't work, I upgraded to Current. The laptop is running very hot and the fans are often running at a high speed so I think the cpu is running near full speed. This is the only issue I am having in general use of the laptop. I will include the url for my asl below as well as the output of dmesg after boot -v and sysctl hw.acpi. I noticed messages like "acpi_ec0: EcCommand: no response to 0x84" near the bottom of the dmesg but honestly don't know enough about acpi to say whether this could be causing the problem. I tried Googling the error and found people who seemed to be having trouble with temperature readings and battery status. For me, the battery status is working fine when I check it via acpiconf although I did notice some unusual temperature readings in the dmesg output. There are some other temperature readings that appear in sysctl but I would have to study them more during a work session to see if they remain reasonable. Thanks in advance for any help. asl url: http://pasted.co/5770b687 boot-v output: http://pasted.co/c8e9fb89 hw.acpi output: http://pasted.co/cc611266 ___ freebsd-acpi@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-acpi To unsubscribe, send any mail to "freebsd-acpi-unsubscr...@freebsd.org"
