I have a laptop which, last night I repaired the Power Jack and now it works. I installed ubuntu last night and it was working fine, this morning I unplugged it and turned it on and it would not boot linux, the startup music / noise would happen but the screen would lock up
I'm going to take pictures of the many different unresponsive screens but the most memorable is a black background with 4 or 5 white boxes (like qrcodes) on the screen.
When I plugged the laptop back in I saw this screen again for a fraction of a second then it booted. Any Idea on how to fix this? The laptop is a an Acer Extensa 4420 if that matters.
I just unplugged it after I wrote this initial post and it completely froze and was unresponsive on the desktop.
