I recently bought a new laptop (an hp probook 450 G5), and installed ubuntu 18.04 on it.
But i have a big issue, when i close my laptop or press the power button to suspend, it won't resume when i want to come back. I just have a black screen.
I updated the kernel, intel-microcode is uninstalled, and this issue is still here and haven't found any solution on internet.
So please, can someone help me?
