You may find that it goes from 40% to 1% in a matter of minutes as my Thinkpads do when their battery's are over a year old. To get accurate battery estimates you need to monitor the life of the battery as it fully discharges. I think that the software on some handheld devices does this, but APM on Linux doesn't. > I was using a PC card modem, network card and made use of the cdrom.

CD-ROM and CPU usage take a lot of power. I can reduce the usable time of my laptop by a factor of 50 by having a CPU intensive process running! -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page
