I was prompted to install a new bios update a few days ago, I let it go through and ever since then, if I shut the lid and put the laptop in sleep mode, opening the lid results in the screen flashing full of ascii boxes repeatedly, then it just goes blank. If I push the enter key it'll just flash again with each press. I end up having to hard reset the laptop before it will restart normally. I'm really upset because this is 8 days out of warranty now. Did Dell sabotage me?
I got it working again. Even though everything is set to automatically check for and install updates, it did NOT install a video driver update. I manually checked for updates using Dell's update utility and it was showing updates for my video and storage drivers. Installed both and now it's resuming from sleep normally.
Could have saved some frustration if automatic updates actually automatically updated!
