coreboot

Is there any documentation on the issue and Windows' behavior?

Since the ToString() calls are in the _BIF and _BIX methods, those ACPI methods fail when called under Windows. Windows then says "No Battery Installed" even though there really is a battery, since the ACPI calls fail.

Seems like ToInteger() also causes issues. This issue was noticed when importing lulu mainboard ACPI code from the chromium coreboot tree. The I2C HID _DSM method was failing in Windows due to the use of ToInteger() and switch() statements. Changing the code to using If statements and not using ToInteger fixed the issue.
