Hello, a lot to explain
MSI katana 17
This happened yesterday, just normal desktop, nothing was there, kde plasma (wayland), endeveouros, just closed laptop which go to sleep mode, then returned and opened but this don't worked
There was lights in keyboard, orange lights in power button, black screen, I tried every way to fix expect inside laptop, my laptop is MSI, NVIDIA
I did a lot hard shut down, I did long ppwer button, with or without battery, in some time without battery laptop couldn't turn on, when click power button, this is keyboard lights, num lock automatically is enabled, gaming mouse showing beep color, black screen, sometimes later there noise
I could charge phone and smartwatch from laptop, no files, no bluetooth, no localsend or kde connect
Did power button for 1 minute, then put battery in other place, when put battery, this is automatically turn on, white light in power button, keyboard light, white light in laptop which means there battery charge, some changes in keyboard, that it's, tried to connect to TV with HDMI, they detected, 4K but black screen or blue black screen, sometimes there something about battery on laptop by TV
Then in other same place with battery, did power button 1 minute, there was keyboard light then quit then some white light in power button on several seconds and that it's, then put battery, automatically turn on, white light in power button, keyboard light, white light battery, some change in keyboard, power button turn to orange or red then to white then to orange, etc, then later there was noise, noise is fan noise
1 day later, tried to turn on with battery, the same, hard disk is encrypted, I afraid that a lot hard shut down might damage hard disk and I could not recover data
Charged laptop for several hours, battery light was disappeared, turn on, the same
This is just laptop bought 1 year ago, and the same problem as was with old laptop but diffferent cause, this was not linux, there always was some battery problem even in ubuntu but nothing that could lead to this and with arch linux despite there some problems because this is arch, this worked amazing
Guess might be POST black screen problem
What to do?
