    This laptop goes to sleep fine when the lid is closed. If the mouse is moved (usually accidentally) while the lid is closed it wakes up-that's OK too. The problem is that it never goes back to sleep until you open & re-close the lid. That's wrong. Is it a setting thing or is it just something they screwed up in the power control software?

    It's also got an overheating problem that I'll look into after I finish configuring our spare to take over the work. I can't really see why that would affect the sleep function although I can certainly see why the failure to go back to sleep might affect the overheating.

    Thanks.

    I'm not sure about the lid issue, other than some obscure setting in those Power Options.
    I had a relative who their laptop they were used to close the lid and it would go to sleep. It started to stay on at one point and the fan running full blast and the fan area hot like a red hot potato. It had sat unused all day with lid shut.
    We went in to task manager and found in the Performance tab that the processor was being used almost full all the time when idle, and then in Processes tab we looked to see what it was that had a very high percentage of use, running constantly. I can't recall what it was, I do believe it was some HP bloatware. Sorry I can't say for sure. But worth a look when its overheating to see if somethings hogging the processor.

    Of course overheating could be age, and or dust clogging the fan too.

    Another thing I see a lot of people do is put their laptops on top of cushions, pillows or right on top of the bed, completely blocking airflow. All the HP laptops I and my family have owned have the fan intake right underneath under the actual fan. We also have a Toshiba that has air inlet in the back or sides and outlets in the side which is slightly better.
    I am always telling people to use a hard surface, then next time I see them its on the carpet blocking the fan.

    It's always used on an elevated mesh stand so I'm certain the airflow isn't blocked-externally, at least. If something's working the processor it seems to stop as soon as I open the lid because I've never spotted it. (I've checked-the closest I've come was one time I found 24 IE windows open-but then I found that they were all WWF games my other had been playing. But it overheats at other times when there aren't a bunch of windows open.)
