Blank Screen when portable hard drive plugged in to USB
Deputy head's fairly new laptop has started playing up:
HP 625 running Windows 7, standalone (not on domain). When he plugs in his Verbatim portable hard drive (model 47628, 250Gb), more often than not the screen is going blank instantly on the laptop. This laptop doesn't have power LEDs for the internal hard drive so tricky to tell if there is any activity going on, but the normal power on light is still lit. Can't get the display back. Did look to see if it had somehow toggled to an external display, but can't find any function key that looks like it will toggle the display between laptop and external. Am new to Windows 7 so don't know if this function has been dispensed with.
Anyway, we have tried two of the three USB ports, with the same effect. I've tried a memory stick and that works fine. He tells me that the hard drive has been fine over the summer with this laptop. And we did get it to plug in fine on one occasion. I've tried the drive in this desktop twice and no issues at all. Dodgy USB cable???? I am having difficulty diagnosing this, as I don't like to keep trying the drive in the laptop and of course can't see anything once the screen goes blank. The only way to get the laptop display back seems to be to force power down, which I'm not amazingly happy about doing too many times.
