X60s Power Manager Settings for MAX Battery Time

What wonderful infomation exchange place!
This Thursday, I am outbound to Australia with my X60s (4-cell and 8-cell batteries, 2-GB Ram, 100MB HDD, 2-GB Compact Flash, 1-GB SD) on an a 747 without seat power available. I would like to operate for the maximum amount of time doing both MS Word work and C/C++ compilations and debug. I have a "headlight" that I wear to illuminate the keyboard and other stuff I may need so I won't need the built-in "light". I have seen a report where someone reported reducing everything to achieve 20w battery drain. The best I have done has been 28+ watts with 0.48 A drain.

Further it seems I only get the 0.52-0.48 drain if I launch the battery manager and switch to "Optimize for power source.." - as hard as I try, I am unable to tweak things to get below 0.70A in any other way. I switch the radios off and run at a fairly low screen brightness.

In the "old days" the thinking was to install the MAX amount of RAM and to use "RAM Drives" so the HDD only spun up when saving through the cache.
When I look at the RAM being used, I still have 1.3 GB available.

Thanks in advance ... best .. Abe

 

You seem to have a good understanding of a notebook's power consumption. The Power Manager has a setting called "Maximum Battery Life". I cannot offer any advice besides selecting that setting and turning off all unneded devices.
