I got up this morning to see my hp touch 816 not responding.   In the last week it seems that it shuts down each night. I did not think I set it to power off?Anyhow I always had problems with ? USB ports. it is like there is not enough power to run all 5 USB ports Some times my printer does not fire.I do an additional USB extender with its own power supply.So after a frightful 30 min’s of trying to power off letting it sit and repowering up to no avail, I then removed all accessories.. namely all the USB plug in’s and it fired . go figure. Hoping this never happens again but am backing up data as we speak.Has anyone else ever experience this??

Hi Bill

Did you ever have a USB device that seemed a bit more difficult to plug in? If so, it may have been plugged in backwards and bent the pins inside the usb port. I've seen it happen before and it can cause a whole bunch of problems from a burned out motherboard to the USB ports working intermittently. Use a flashlight to look at the ports and see if you can see any bent pins. If you can, then there is one of your problems.
On the other hand, I have a similar problem with my TX2500 tablet. I have one USB port that whatever I plug into it causes my tablet to freeze. It happens both in Win7 and Vista so I know its a hardware porblem. I looked at my port though and everyting looks fine.
Since you were able to identify which port causes the problem then I would avoid that one and continut to use the powered hub for your devices. I do the same with my touchsmart and its much more convenient.

thanks but no i don't think that ever happened
but does seem like these 4 USB ports are under powered and intermitantly work
I currently use a USB expansion card plugged in with it's own power supply and that seems to work ok.

BTW I can never disable the built in microphone to use and inline microphone ( eg head set)
these ports are acting werid
