Misc :

11524 method          Test 61 of 92: Check _WAK (System Wake).
11525 method          Test _WAK(1) System Wake, State S1.
11526 method            Package has 2 elements:
11527 method              00: INTEGER: 0x00000000
11528 method              01: INTEGER: 0x00000000
11529 method          WARNING: Test 61, _WAK: expecting power supply S-state (element 1) of packages
11530 method          to be 0x00000001, got 0x00000000.
11531 method          
11532 method          ADVICE: _WAK should return 0 if the wake failed and was unsuccessful (i.e.
11533 method          element[0] is non-zero) OR should return the S-state. This can confuse the
11534 method          operating system as this _WAK return indicates that the S-state was not
11535 method          entered because of too much current being drawn from the power supply, however
11536 method          , the BIOS may have actually entered this state and the _WAK method is
11537 method          misinforming the operating system. Currently Linux does not check for the
11538 method          return type from _WAK, so it should theoretically not affect the operation of
11539 method          suspend/resume.
11540 method          
11541 method          PASSED: Test 61, \_WAK correctly acquired and released locks 8 times.

Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.
S1 Sleep Supported	false
S2 Sleep Supported	false
S3 Sleep Supported	true
S4 Sleep Supported	true
Platform Power Management Capabilities:Adaptive Display Brightness is supported.
This computer enables Windows to automatically control the brightness of the integrated display.
