input voltage switch?

[Corny11]

We have moved from USA (120v) to England (250v).    We just blew up the power supply on our Dell computer because we were not aware of the input voltage switchover switch.  Next, our HPw2007 monitor says 120v-240v.  But is there a switch somewhere or other adjustment we must make before plugging it in?

Thanks to anyone who has faced this.

@Corny11 -- our HPw2007 monitor says 120v-240v.  But is there a switch somewhere or other adjustment we must make before plugging it in?

If you carefully inspect your monitor, and you do not see such a switch, you can safely assume that there is no such switch, especially because the label states "120V-240V" compatibility.

Hi

"We just blew up the power supply on our Dell computer because we were not aware of the input voltage switchover switch. "

sorry for that, see with your insurer if not already done
We don't always know it, sometimes we are covered for accidents of this type

check and read the documents well, but normally no such button

If this one
