E5520 Clover boot menu does not recognize keyboard and touchpad

Recommended Posts

Hi all, I ran into something very weird. I have been using the Clover guide (see link below) to install OSX Sierra on my Dell e5520. I went through all the steps and ended up with a bootable USB. However, when booting Clover from the USB stick, I end up in the boot menu and the computer does not respond to keystrokes and mouse movements. I have tried different things, including putting the laptop in the docking. And to my surprise I can now use the mouse and keyboard connected to the docking to operate the boot menu, but the keyboard and mousepad of the laptop are still not responding.

 

Using the docked keyboard and mouse I was able to finalize the Sierra installation and it works like a breeze, but when undocked I cannot use the laptop as I need to press [Enter] in the Clover boot menu to boot OSX from the SSD. So the Clover boot on my SSD shows the same behavior as the one on the USB stick (which makes sense, essentially being the same version).

 

What is really strange: if I prepare a bootable USB using unifail, I CAN operate the Clover boot menu with both keyboard and mouse (but then I run into a boot issue, which is why I am keen to use the osxlatitude method).

 

My questions:

- Has any of you ran into this issue and fixed it? If so, please share the solution with me. :-)

- As an alternative solution skipping the Clover boot menu and automatically booting OSX from the SSD would be a solution as well, but I cannot find how to configure this in Clover (tried several options in Clover Configurator like setting the boot delay to zero, but that did not resolve my issue.

 

Thanks for your input to this!

In Config file, under boot, set the Default Boot Volume with the name of your SSD. (Case sensitive), Set Timeout to 1 or 2 seconds.

Done! And it works. Thank you!

 

Great! I have some questions for you. if you know .... Do you have any hi pitch noise? What sound card driver do you use? Is the brightness control work and shows brightness change with a message on the screen or only change brightness? The delete key in your keyboard is working?

No hi pitch noise. Perfectly quiet. Brightness control works without icon on screen. Sound control works and shows icon on screen. Both brightness and sound control do not always remember the last value, so need to set again after reboot. The delete key works perfectly.

 

As written in the initial post, I have used the guide from OSX Latitude for the E5520 and it works flawlessly now.

 

However, there is one thing with power management I am still working on: booting from battery results in a kernel panic and removing the power plug when the system is running hangs it after 2 seconds. So I think power management (ACPI) is not yet configured correctly.

hmm that is opposite to what happened on my E5420. i can boot and run fine on battery but once i connect the charger the machine goes crazy. even the backlight starts to strobe on and off rapidly.

That is really weird. I am troubleshooting my issue. When (if) I found a solution, I will post it here.

Also in my setup both brightness and sound control do not always remember the last value, so need to set again after reboot as well! I use Sierra .4 version and I have this high pitch noise especially when i run on battery, but no kernel panic at the moment. Just this high pitch when i run on battery it is not so hard i can afford it, but i am afraid for any damage in hardware level. I can make more tests if it is required and post back here. I use the configuration from the tutorial here in osx latitude and i update only the sound driver from the files below the tutorial, but it does not fix the hi pitch. I will try this laptop with Linux to test if makes this sound and i will post back.

The guide is working in my e5520. I have high pitch noise that might come from voltage regulators (update: this is not completely true , the sound is more commonly  to come from speakers). I plan to fix the problem and post back!
