General Technology & Troubleshooting Topics

Hi to all, first time user of this forum.

I recently bought a Satellite P505D-S8930 notebook and it works great, however, I needed more USB2 ports so I bought an externally powered 4 port hub. The hub works great but when I close the lid on my notebook the whole system shuts down rather than the notebook going into sleep mode.  I open the lid again and the notebook is dead!! Pressing the ON button doesn't even wake the notebook up. I actually have to unplug the external hub, take the battery out and then put it back in, and then wait approx. 5 minutes before the notebook will power back up again.  I decided not to use the external hub and see if there were any problems and the notebook works like new. I also noticed the battery had drained whilst the external hub was plugged in and the notebook was in sleep mode.  Anyone got any ideas why this is happening?? And is there an external multiport USB2 hub that is specifically good for our Toshiba notebooks???  Very eager to find out if anyone else has had this sort of problem.  Any assistance offered would be appreciated.  Thanks in advance......BAZ

Try this. Open Device Manager (devmgmt.msc), expand Universal Serial Bus controllers, right-click on a USB Root Hub, click Properties, and look on the Power Management tab.

If there's a setting like this, uncheck it.

   Allow the computer to turn off this device to save power.

You may need to play around with these a bit.

Hi Jerry,

thanks for your response.

Sorry for the delay but I had to try a couple of experiments, including yours, to see if the power management feature would work. Unfortunately, the laptop shut down and I had to go through the whole procedure of booting it back up like previously mentioned.  Sincere thanks for your help anyway.  Any other ideas??  Regards BAZ

Mystery to me. What happens with a different hub?

Hi Jerry,

I used the same 4 port hub but without the power supply connected to it and all worked well, with the exception that it works much slower (which is not good for me). I haven't managed to get hold of another powered hub as yet. A mystery to me nevertheless. Maybe I might have to get in touch with Toshiba and see if they have a solution to this problem.  BAZ

Thanks for that update, Baz.

I use power hubs here (with different laptops) and have never had that sort of trouble.
