<p>Q: I purchased an HP laptop with Windows 8, and an HP 5520 printer. When the printer was installed as a wireless printer, it seemed to affect how the laptop acted when in a sleep mode.</p><p>I am guessing that it's the sleep mode that is affected when the wireless printer is on. When the printer is off, the laptop goes into a sleep mode that can be reawakened easily to the lock screen.</p><p>When the printer is on, the laptop screen goes dark as if it is in a sleep mode, but the laptop can't be reawakened unless I power down and restart the laptop.</p><p>This situation occurs regardless of whether I start with the printer off, but the printer is turned on during the session to print a document, and subsequently turned off before the printer goes into the sleep mode. It seems that the printer is sending a message to the laptop not to wake up.</p><p><a href="http://seattletimes.com/html/businesstechnology/2021053040_ptechqa25xml.html">Keep reading...</a></p>
