Hi. My zt3000 doesn't completely wake up from standby mode anymore. The screen is black, and I have to turn the machine off and on again. Has anyone else experienced the same? This happens both when the lid is closed and reopened, and when the pc automatically enter standby mode...
I haven't seen that specific issue, but I have noticed more problems coming out of standby lately. I'm not the full-time user of the machine anymore, but my dad uses it daily and always puts it to sleep. The few times I've tried to use it, at least once or twice it's failed to come out of standby. I don't remember whether the screen stayed black or not though.
Which version of graphic driver are you using? I had the same problem as you have and solved the problem by downgrading graphic driver ( found in HP website). Don't use the latest one on driver download website from HP. Use older one.
I hope this is helpful.
