===== Notes =====

Rather cheap-looking, inexpensive laptop with mediocre screen and craftsmanship.  It got my interest solely because of AMD APU (unfortunately, Intel rules these days, and almost no vendors except HP and Lenovo produce AMD-based laptops).

Comes with Windows 10 preinstalled.  Getting into UEFI BIOS is possible by pressing F9 (as I vaguely recall) early in the boot process.  Disabling [[/SecureBoot|SecureBoot]] allowed to boot off USB memstick, flashed with 11.0-CURRENT-[[http://svnweb.freebsd.org/base?view=revision&revision=295683|r295683]]; ''%%vt(4)%%'' is required if you want to see anything on the console.  KMS appears to work with ''%%radeonkms.ko%%''.  X11 was not tested.

==== ACPI issues ====

Suspend/resume does not work, in somewhat special way: looks like laptop fails to suspend (tried with ''%%zzz(8)%%''), and after some ''%%dmesg(8)%%'' message storm you'll find yourself back at the command prompt (keyboard also remains working).  ACPI-related errors in the logs:

<code>
ACPI Error: No handler for Region [RCM0] (0xfffff80003dac080) [SystemCMOS] (20150818/evregion-176)
ACPI Error: Region SystemCMOS (ID=5) has no handler (20150818/exfldio-317)
ACPI Error: Method parse/execution failed [\134_SB.WMID.ESDT] (Node 0xfffff80003dc0a00), AE_NOT_EXIST (20150818/psparse-558)
ACPI Error: Method parse/execution failed [\134_SB.PCI0.LPC0.EC0._Q42] (Node 0xfffff80003dc1e00), AE_NOT_EXIST (20150818/psparse-558)
acpi_ec0: evaluation of query method _Q42 failed: AE_NOT_EXIST
</code>

==== Possible remedy for immediate resume due to SystemCMOS ====

:!: Apparently, this is a common problem with many contemporary HP laptops, and happens due to %%FreeBSD%%'s lack of an ACPI CMOS RTC handler.  See [[Laptops/HP_Envy_6Z-1100]] page (there is a patch).
