From d8f444f8caf1f0c980b61dd3f39d420780d73ab7 Mon Sep 17 00:00:00 2001 From: John Chau Date: Mon, 5 May 2025 01:55:13 +0900 Subject: [PATCH] platform/x86: thinkpad_acpi: Support also NEC Lavie X1475JAS MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit [ Upstream commit a032f29a15412fab9f4352e0032836d51420a338 ] Change get_thinkpad_model_data() to check for additional vendor name "NEC" in order to support NEC Lavie X1475JAS notebook (and perhaps more). The reason of this works with minimal changes is because NEC Lavie X1475JAS is a Thinkpad inside. ACPI dumps reveals its OEM ID to be "LENOVO", BIOS version "R2PET30W" matches typical Lenovo BIOS version, the existence of HKEY of LEN0268, with DMI fw string is "R2PHT24W". I compiled and tested with my own machine, attached the dmesg below as proof of work: [ 6.288932] thinkpad_acpi: ThinkPad ACPI Extras v0.26 [ 6.288937] thinkpad_acpi: http://ibm-acpi.sf.net/ [ 6.288938] thinkpad_acpi: ThinkPad BIOS R2PET30W (1.11 ), EC R2PHT24W [ 6.307000] thinkpad_acpi: radio switch found; radios are enabled [ 6.307030] thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver [ 6.307033] thinkpad_acpi: Disabling thinkpad-acpi brightness events by default...
