I’ve got a black Samsung NP-NC10-KAP1PL. It’s a version with integrated GSM modem from polish network Plus.
Recently I’ve upgraded BIOS from 00CD to 03CD. Two BIOSes look exactly the same, same options, however I think the power consumption is slightly liwer.
Configuration: Samsung NP-NC10-KAP1PL with 2GB RAM.
Running software: Windows XP SP3 home, standard Samsung programs, net limiter, Kaspersky Internet Security 2009, Battery status 0.98 (taskbar mode, sample rate/method= 5/smoothed)00CD [03CD]

[14.0]Of course the tests are far from being accurate, but I was trying to replicate the same conditions for both BIOSes (same movie files, same software, same sequence of tests starting from 100% battery).
Nice test! I was wondering what changes where made and should I apply the update. Now I know 🙂
I also noticed that the fan turns on less often then before.
Anyway it would be cool if such tests where published after each bios upgrade… I know it takes a lot of doing but due to lack of any official change logs we would at least know that the new bios doesn’t make things worse….If there will be new BIOS for my model, I’ll do the test again.
It really doesn’t take so much time – much less then “the rigt way” of doing it ie. with some battery test program, run few times on different settings 🙂
