解决了问题 由此突发奇想 修改了我的SSDT 由于我的是IF语句 都同样起到循环的效果
第一步
Method (_OFF, 0, Serialized) // _OFF: Power Off
{
If (LEqual (CTXT, Zero))
{
\_SB.PCI0.LPCB.EC0.SPIN (0x96, Zero)
If (LNotEqual (GPRF, One))
{
Store (VGAR, VGAB) /* \_SB_.PCI0.PEG0.PEGP.VGAB */
}
Store (One, CTXT) /* \_SB_.PCI0.PEG0.PEGP.CTXT */
}
SGOF ()
}
删掉了红色部分的IF判断语句 直接运行结果 改为如下
Method (_OFF, 0, Serialized) // _OFF: Power Off
{
\_SB.PCI0.LPCB.EC0.SPIN (0x96, Zero)
Store (VGAR, VGAB) /* \_SB_.PCI0.PEG0.PEGP.VGAB */
Store (One, CTXT) /* \_SB_.PCI0.PEG0.PEGP.CTXT */
SGOF ()
}
第二步
然后修改_PS3函数 如图同样的方法不进行判断 直接运行
未修改
Method (_PS3, 0, NotSerialized)
{
If (LEqual (OPCE, 0x03))
{
If (LEqual (DGPS, Zero))
{
Store (One, DGPS)
}
Store (0x02, OPCE)
}
Store (0x03, _PSC)
}
修改为这样 再所有语句之前加入_OFF() 如果有的话就不用加 自己判断 大同小异
修改后
Method (_PS3, 0, NotSerialized)
{
_OFF ()
Store (One, DGPS)
Store (0x02, OPCE)
Store (0x03, _PSC)
}
