Pwr Options
Dell Vostro; bios & chipset updated, Vista Business updated
No other hw connected, no background tasks running, printer switched off, sys runs 24/7 Ever since installing a usb connected HP photo printer (includes scanner) - firmware & drivers upto date - the pwr options have become eratic. ie sometimes screen saver & pwr off display functions, other times not. The screensaver can kick in then without any user going near the PC the desktop becomes active I've tried resetting & changing Pwr Options, ensured usb hubs have the option to allow to be turned off set - mysteriously on occasions this option has been reset. Screensaver set to 10 minutes but generally wont start for at least 45 minutes No events logged This is 'she who must be obeyed' PC the new printer was purchased because she wanted to do a lot of scanning / printing of photos and didnt like my HP business class printer that was connected via the wireless printer server. HP states its a Dell bios problem, Dell says nothing Any thought? T/Y |

Pwr Options
Wait for a more knowledgeable answer, but I'd like to mention this:
HP printers, even $70 little cheapies, come with sometimes half-Gigabyte worth of software. As you might guess, instead of good old approach where you install a driver and done, or it gives you an option to add add-ons (photo, graphics/etc utilities HP thinks you need, but you really don't); nowadays companies install a thick forest of BLOATWARE. In plain English your printer installed more than just drivers, but certain conflicting bloatware you need to uninsatll or at least disable in Services. Now goto Services console and find what appeared there new, start disabling naything that starts with "HP" but ONLY after Googling Web for each service meaning, so you won't disable an essential Windows process!! For example, my HP 6940 (?) besides drivrers attempted to install various photo and connectivity agents known to conflictwith Vista's power manegemnt. it's impossible to shutdown when this garbage runs on some computers. I was lucky I never had problems but still disabled HP Net12, HPmonitor, HP port resolver, etc I dont remmeber. When power management restored to normal, I started reenabling those services until I pinpointed the culprit which broke Power controls in Vista. It was some kind of HP software discovering netwroks, etc... I dont remember, 2 years ago. So see what services this printer added. Also be sure you insatlled HP drivers for Vista 32 bit if thats your case. Do NOY trust CD that came with your printer, or Vista's own driver. Goto HP website and search for you rprinter, see if an update exists, in my case 2 updates were posted resolving "severe instability" on some machines, if I trusted CDtha tcame with HP printer I'd be in trouble. This happened because WinXp drivers existed and were polished to perfection for years, while Vista was still new at that time. SO drivers were buggy....
