How to patch DSDT for working battery status

Great guide RehabMan! My problem is: SMD0, 264, //Offset (??)
OperationRegion (ERAM, EmbeddedControl, Zero, 0xFF)
Field (ERAM, ByteAcc, NoLock, Preserve)
{
Offset (0x18),
SMPR, 8, //18
SMST, 8,
SMAD, 8,
SMCM, 8,
SMD0, 264, //??
SMAA, 8,

I read “ The offset of any given item is the offset of the prior item + prior item size in bytes, unless an Offset directive is used to change the effective offset” but i don’t understand because my english not good. Can you help me? Thank you very much!

Simple math...

Field (ERAM, ByteAcc, NoLock, Preserve)
{
Offset (0x18),
SMPR, 8, //18
SMST, 8, //19
SMAD, 8, //1a
SMCM, 8, //1b
SMD0, 264, //1c
SMAA, 8,

It would probably make more sense to rename LPC -> LPCB (Macs use LPCB).

Post your DSDT if you want me to look at the possibility of doing that in the patch repo.

I'll put it in the thread of the dv5-1030el, along with all the other changes I made

Thanks. It’s working, but Sometimes battery icon not showing in the menubar? Please help me!

Even though there seems to be already a patch in the repo for your laptop, the one you wrote looks ok.

Use the debug version of ACPIBatteryManager.kext to determine if anything is going wrong in your battery methods.

Patch battery_ASUS-N55SL.txt working with ASUS X401A-WX108.
My question:
I think SMAD, SMCM, SMD0 is //20, //21, //22.
Why it's //1a, //1b, //1c.

Which patch? There are many.

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

System: manufacturer/model
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

System: ASUS PRO PU401LA
CPU: i5-4200u/PU401LAC
Graphics: HD4400, 1366x768

That was my mistake, I applied someone's patches on Dell Latitude forums with the same specs with me, maybe that causes some errors like that.

Here is my DSDT dumped from Ubuntu

Thanks for your interest.

Looks like the "ASUS G75VW" is applicable.

Has anyone made a patch for a Lenovo ThinkPad T61 and would share it?
