My multiport converter is shutting down my laptop

by berful / November 25, 2008 3:05 AM PST

I have a Dell Latitude D430 running xp pro and recently purchased a Coolmax multiport converter to transfer some data from another drive. When I connect the USB cables to the laptop it just powers off the laptop. I know the converter works as I have tested it on another machine. Any ideas why it would take down the machine every time it is connected?

No idea why, but I have one WAG you can try. Try a powered USB Hub. Plug the hub into your laptop, then plug your gizmo into the hub.

Maybe it works maybe it just powers down your laptop. What's changing is that the powered hub should draw less power from your laptop than your gizmo directly. If that's whats causing the shut down, then maybe this will work around it.

Sorry but I think its proper as its trying to use the USB as a hard disk power source. There are limits on some but not all machines so I don't expect anything but a proper supply to fix it.

Thanks I will give it a go and see what happens. The converter has it's own power supply by the way.

The unit I found by that name didn't have a power supply. There are other causes such as a re-loaded OS and some one forgetting motherboard drivers.

Ok, This is a 4 month old laptop and a month ago the hardrive failed. Dell sent me out a factory preloaded replacement that I installed. I have downloaded all win patches and updates but I have not checked into any driver omissions. Everything else works great but I will look into that.

Thanks again for all the help.

Happy Thanksgiving!

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
