Method (_BST, 0, NotSerialized)
{
Store ("==Main Battery Status _BST==", Debug)
If (LGreater (ECDY, 0x00))
{
Decrement (ECDY)
Notify (\_SB.PCI0.LPC0.BAT1, 0x81)
}
IMO, the value of ECDY is really meaningless in this BIOS, and we can reset it
to 0 freely.
But I'm afraid it's hard to get it fixed in the upstream kernel as
1. it's a BIOS issue.
2. a possible workaround is to evaluate _BST method for 3 times when Linux
tries to get the AC state for the first time. but unfortunately mixing up two
drivers won't be accepted by upstream kernel. :(
so please make sure if you're using the latest BIOS release.
If yes, either you can use the customized DSDT or Yakui can generate a patch
for you to workaround this issue, which will not be upstream.
