Interesting idea! I'm pretty sure it's impossible. The 750C doesn't
have an LCD display to fall back to. There are three transistors per
pixel on active matrix displays, and, as the saying goes, "The wolves
have to be fed!" Short of going into standby or suspend mode, if the display
is on, whether the pixel is on or off, some amount of power is bleeding
thru each transistor, and running the battery down.
The most practical way to get 7 hours of power
is to buy a second battery pack and use
the power saving features. Also, planning your work to reduce disk
accesses. This may include avoiding programs that go to the disk every
20 seconds to get an overlay or dynamically
linked programs (like windows does), setting
up a RAM drive, and running the processor slow.
Off-the-point, last piece of advice: if your main need is word/text processing
and multiple file access, and perhaps some lite communication, spreadsheet,
and mail, consider getting a palmtop. I'm using one now. It runs
about 2 weeks on 2 AA batteries, has a PCMCIA slot, mail, lotus 123,
runs Freemacs (or any DOS based wp, fits in my shirt or pants pocket
easily, and now sells for ~$500.
