Lenovo Thinkpad t480s, Mojave

[thinkbook]

Hi, I installed Olarila ISO image for Mojave unsing Clover Vanilla Guide. Afterwards I used this EFI

--NOTEBOOKS CHIPSET SERIES SKYLAKE+ (SKYLAKE / KABYLAKE / COFFEELAKE / WHISKEYLAKE / COMETLAKE)

and the video patch for "-HD620 and 630 8th"

Hope, this selection was correct?!

I use a Lenovo Thinkpad T480s with

• Processor: Intel Core i5-8250U 4 x 1.6 - 3.4 GHz, Kaby Lake Refresh
• Graphics adapter: Intel UHD Graphics 620, Core: 1100 MHz
• Memory: 8 GB + 16 GB , DDR4-2400
• Display: 14 inch 16:9, 2560 x 1440 pixel 210 PPI, LP140QH2-SPB1, IPS, glossy: no
• Mainboard: Intel Kaby Lake-U iHDCP 2.2 Premium PCH
• HDD: Samsung 970 EVO NVMe M.2, 500 GB
• Wifi/Bluetooth replacement: Broadcom BCM94352Z DW1560

I hope, regarding this spec, my choice regarding EFI-folder and video patch was correct?

Attached I add my RunMe output.

The following problems I can see:

1. video flickering during boot process
2. Bluetooth not working
3. LAN-adapter not working
4. Battery indicator not showing up
5. USB-ports seem to be extremly slow (data transfer)
6. No sound device showing up.

I would be very happy about your support and thank you in advance

[thinkbook]

Using first EFI FULL:

• Battery is showing up - but tells me that the time to fully charge is about 20 hours - but I can it loading (72%, 73%)
• Brightness keys working
• External monitor is still pink
• Audio interface is still missing
• Bluetooth is still missing
• LAN adapter still not found

• Brightness keys work
• Battery is fully charged and no remaining loading time is showing up

I will check out the links regarding pink HDMI and audio later today

Thanx for now

[MaLd0n]

Enjoy!

audio just change alcid=3 to other number, like alcid=13

just check all options for ur audio codec

[thinkbook]

Perfect Audio is also working. For alc257 the following layout-ids are available:

• 11
• 18
• 86
• 99
• 100

I set alcid=11 for now

Hi MaLdOn, I think there is still somethin wrong with the battery. In the system activity tool I can see that the remaining power is always showing 20 hours. And, the machine seems not to detect, when power is empty - as the machine turn off hard having a sudden power loss.

Anything you can fix?

Kind regards

When using the suspend function - sometimes I can't wake up the laptop anymore. The power button and the red cover led are blinking as expected - but pressing the power button or any other button do not wake up the laptop always. Also, closing the lid and reopening does not power it on again. I am not 100% sure - but it can be that this happens only when I suspend the laptop with power cord plugged in, remove the power cord and then try to power on.
