battery volume can't be showed

[xuyinxiong]

I put the .aml files in the ACPI/Patch, but the battery can't be recognized. Is there other patch for T490 battery?

hmm weird, are you using my EFI as-is or just the battery patch? What model is your T490? Mine is 20N3 for example.
And no, I don't think there's another patch for the T490 battery specifically, the one included in this repo is the only one I know of and I made it myself.

thanks for your quick response. Yes, I used your EFI and my model is same as yours 20N3. Now the battery volume is 0% and the trackpad isn't drived.

Someone else had a similar issue #6 and we weren't able to fix it I'm afraid. Are you on the latest BIOS?

[xuyinxiong]

yes,I think I got the same issue

hi Yusifsalam
I replaced ssdt-plug.aml with SSDT-PLUG-_SB.PR00.aml which I downloaded from OC-little. Now battery indicator and touchpad worked.
thanks

Glad to hear that and thanks for reporting your solution
