Problem

Everytime my system reboots / starts after shutdown / sleep, it does not boot at all. I suppose it fails to init (POST) after shutdown. CPU and DRAM Error POST Error LED are lit up on start. CMOS Reset by removing the coin battery (or at least unplugging the AC power cord and waiting 10 ~ 20 seconds) work. Some say it is RTC problem, so I tried to enable DisableRtcChecksum, but it didn't work. Tried RTCMemoryFixup too, but it didn't work. Please help.

Additional information request are welcome. Thanks for reading long post.

inject rtc with these properties and check if work

Current RTC0 Device checked with MaciASL is defined as below.
 

Device (RTC0)
{
    Name (_HID, EisaId ("PNP0B00") /* AT Real-Time Clock */)  // _HID: Hardware ID
    Name (BUF0, ResourceTemplate ()
    {
        IO (Decode16,
            0x0070,             // Range Minimum
            0x0070,             // Range Maximum
            0x00,               // Alignment
            0x02,               // Length
        )
    })
    Name (BUF1, ResourceTemplate ()
    {
        IO (Decode16,
            0x0070,             // Range Minimum
            0x0070,             // Range Maximum
            0x00,               // Alignment
            0x02,               // Length
        )
        IRQNoFlags ()
            {8}
    })
    Method (_CRS, 0, Serialized)  // _CRS: Current Resource Settings
    {
        If ((HPEN == One))
        {
            Return (BUF0) /* \_SB_.PCI0.SBRG.RTC0.BUF0 */
        }
        Return (BUF1) /* \_SB_.PCI0.SBRG.RTC0.BUF1 */
    }
}

How should I apply it? Remove the BUF1?

For anyone using this board - the internal USB LED Controller is the culprit, so disable it with USBMap.
