usb-powered scanner on hp laptop?

I want to buy a cheap second scanner for my wife to use with her laptop. I'm
leaning towards the Canon lide50 scanner which is under $100 and includes
photoshop elements 2.0. It happens to be powered through the usb cable (no
AC adapter) and I wanted to make sure it will work off a laptop. My concern
is that it might be too hard on the laptop's power supply. I realize the
laptop's ports are powered, but are they powered just enough for mice? She
always plugs in the laptop; it won't be trying to go on battery. The laptop
is a HP ze5170 (p4 2.0) with usb 1 ports. Other things connected to the
laptop are a mouse (usb) and a wireless card in the slot. I realize the
scanner will be slow but that's fine. I have a fast hp scanner for MY stuff,
but it's not portable enough for what she needs it for. And I was going to
buy photoshop elements 2.0 anyway, so this would be a great buy for me if it
will work. But I sure don't wanna fry the laptop, or find out the scanner
won't work without going out and buying a powered hub (not an option as she
wants as few doodads to worry about as possible). Anyone have any experience
with that? Thanks in advance.

Hi John -

I can run my Canon N1240U scanner, which gets it's power from the port,
using the USB port on my Sony R505EL laptop without any trouble. The
scanner draws 500ma of power, exactly the specification for what the port
supplies.

Hello John,

I'm using an HP Scanjet 4570c on a Dell Inspiron 1100, P4 2.0ghz with
384megs of memory. It works great.

You can find the power limit on your usb port in Device
Manager/usb/roothuv/power. Compare that to the power needed by the
scanner.....
