You could probably configure an hp with intergrated graphics to meet those specs, although you should probably spend alittle more and get MS Word, at least, I'd get office 03 basic at a bare minimum. Here's a V6000T like the one I designed for my sister when she went to college:
Operating System Genuine Windows XP Home Edition
fairly standard
Processor Intel(R) Core(TM) 2 Duo T5200(1.60GHz/2MB L2Cache)
Core 2 Duo is the best line of processors in production at the moment, although for a school work PC (typing papers, web surfing, etc.) you could save a few bucks with an AMD based system and not notice the proformance difference
Display 15.4" WXGA BrightView Widescreen (1280x800)
The upgrade is free at the moment
Graphics Card Intel(R) Graphics Media Accelerator 950 w/Ports
forced by hp will burn some system memory
Personalization Imprint Finish + Microphone + QuickPlay
forced by hp
Memory 1024MB DDR2 System Memory (2 Dimm)
1gb
Hard Drive 80GB 5400RPM SATA Hard Drive
You could get away with less disk space, but it isn't that much more money
Primary CD/DVD Drive DVD/CD-RW Combo Drive
default
Networking 802.11b/g WLAN
default
Primary Battery 12 Cell Lithium Ion Battery
My sister only has to charge her battery every 3-4 days, although that will vary with usage, she has a Pentium M not a core 2 duo based system
Productivity Software Microsoft(R) Works/Money
default
