elBuey Posted August 27, 2021 Share Posted August 27, 2021 Hello guys, I've successfully installed Big Sur 11.5.2 on a Bangho BES 1308 laptop. Its specs are the following: Processor: Intel i5 3320M (Ivy Bridge) Chipset: C216 WiFi: Intel Centrino Advanced-N 6235 Sound: 7 Series(C216 Chipset Family High Definition Audio Ethernet: Intel (R) 82579M Display: Intel HD Graphics 4000 There are 3 issues that still bother me a bit: 1- Battery reading is not working, not shown at all. In fact, "Battery" is not even shown in System Preferences. 2- The touchpad is not working 3- The webcam is not working I am attaching the EFI folder I am using, inside which you can also find the DSDT dump. Any suggestions will be much appreciated. Thanks in advance. EFI.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted August 27, 2021 Moderators Share Posted August 27, 2021 1) you'll need to patch your Battery - or try ECEnabler.kext 2) you'll need to know your hardware, what touchpad is it? synaptics, Alps, Elantech ...other unknown 3) you'll need to patch for USB, try enabling XhciPortLimit since you have USBInjectAll.kext installed Link to comment Share on other sites More sharing options...
elBuey Posted August 27, 2021 Author Share Posted August 27, 2021 Thank you very much, Jake! 1- I've tried ECEnabler, and it hasn't made any difference. I've never heard about patching battery, is there an instructive I could follow you can share with me? 2- Is there any software you can suggest for getting the full specs of the hardware? 3- I'll try and let you know.

Moderators Jake Lo Posted August 27, 2021 Moderators Share Posted August 27, 2021 1) See legacy https://dortania.github.io/OpenCore-Post-Install/laptop-specific/battery.html#dual-battery 2) Check website for windows drivers, it might give details of what touchpad it is. Check device manager in Windows Link to comment Share on other sites More sharing options...
elBuey Posted August 27, 2021 Author Share Posted August 27, 2021 I have solved the touchpad with a kext for older laptops. Tried enabling XhciPortLimit but the webcam is still not recognized. Using USBMap I identified the port to which the fingerprint sensor is attached, and the one to which the Bluetooth is connected, but found none saying anything related to the webcam. Any other ideas to explore? Regarding the battery parching process, I went through Rehabman's guide but didn't really understand the process much. I guess I'll have to accept I won't be able to know how much battery is left. Thank you very much for all the help. I tried disabling the webcam with the keyboard shortcut and enabling it back, and after I enabled it back, a notification showed on the top right corner of the screen. You can see it attached. Does this trigger any ideas? Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted August 31, 2021 Moderators Share Posted August 31, 2021 Give this a try, add DSDT to /EFI/OC/ACPI and replace the Config file File edited from your 1st post. If you have made changes since then, post the updated file FixBat&USB.zip Link to comment Share on other sites More sharing options...
elBuey Posted August 31, 2021 Author Share Posted August 31, 2021 Thank you very much Jake! Is there any other change besides replacing the three SSDTs I had with the DSDT.aml file? If only that, I can change the ACPI - Add part of the config.plist file for making it work. Otherwise, I'll post my current EFI (with trackpad working) for you to help me. Thanks, elBuey.
