My husbands laptop randomly decided to go into "sleep" mode. He had selected sleep, shut the top, walked away and went to bed. Next morning he opens it and it does its wonderful mind-boggling complication of not wanting to have anything but a black screen, not a powered on black screen, just nothing... Yet, the system was trying to run anyway. ~confuzzled~
So, I do a google search and this is the first place I come across. Nanor, your advice is fantastic. I have no idea how you managed to figure out the hokey-pokey-dance to get this trick, but thank you for the time invested in doing so.
I tried the original: Remove battery, hold power button, plug in power cord, reboot,... still had the black screen", so I scrolled down and read a few more posts. So I redid the song and dance back up to the reinsert the power cord and turn it on, but instead of opening the lid all the way, I opened it just far enough to reach the power button, this did the trick; the screen lit up! and the boot process was clearly visual again! ..."continued to do a proper "shut down", reinsert battery, etc etc. powered up again and everything was just peachy!
