My Spectre has developed a video problem. This morning I came into the office and the display was "smeared." I have an external display so I started my day working on that, and after an hour or so the laptop display magically fixed itself. 6-7 hours later, the smearing started again, and stopped again after a few hours. All without being touched.
So it starts and stops without any physical touch at all. I tried poking, prodding, tapping, etc and I can't find any loose contacts or similar. Rebooting had no effect; the smearing continued on the boot/splash screens.
I don't believe it can be a graphics-driver problem, since I observed the smeary video persisting all through a reboot -- from OS, to BIOS splash, to OS splash, back into OS. Graphics drivers aren't even loaded during the initial boot process.
BIOS seems unlikely but possible. HP just released a new BIOS 6 weeks ago. I will install it and see if anything changes. The behavior is extremely intermittent - it hasn't done it since I posted 4 days ago -- so it will take a while to see if it has been fixed.
