Why does my external hard drive turn off when I connect it to my laptop but works fine on my desktop?

Q: Hey, I have a problem with my external Hard Drive. It turns off when I connect to my laptop. This does not happen when I connect it to another PC so I wonder if anyone of you guys know the problem? :)

    Is the drive USB powered? If so you might have powered ports on your desktop but not on your laptop.

    Do you have any other USB devices to test on the laptop and verify they are working?

    No, the hard drive has it’s own power supply and work on all other pc’s than mine (all have Windows 7, same as mine). Other USB devices also work on my laptop. What’s strange is that my HD shuts down after 20-30 seconds and between this I can use the programs on it..
