Hasee A500C,could not detected battery in all linux platforms,but win7 can detect it.
The errors in dmesg are as below:

It says that the methord _BST has something wrong.So I dump DSDT from my system and disassemble it by iasl.The _BST method is as below:

Method (_BST, 0, NotSerialized) // _BST: Battery Status
{
Name (PKG1, Package (0x04)
{
0xFFFFFFFF,
0xFFFFFFFF,
0xFFFFFFFF,
0xFFFFFFFF
})
Store (And (ECRD (RefOf (B1ST)), 0x07), Index (PKG1, Zero
))
Store (B1CC, Index (PKG1, 0x02))
Return (PKG1)
}

How can I solve it?

Try telling ACPI that the OS type is windows? Sometimes they give different tables/code to linux...
