Hello all, its been so long since my last thread. now im back here again to ask one common question: How do I calibrate my battery precisely? so here's the case, before this, my laptop specs are in my profile. hence i just jump to the battery specs to be more specific. the battery is SANYO ZL-01 Lithium Ion Battery, 4400mAhr, rated at 14.8V. i do know the real-time info from the software called Notebook Hardware Control. its very useful for viewing battery capacity info. enough for the intro i guess, so the battery full capacity it 65120mwh when it's new. but now its less than 30000mwh. it was 26000 just now, until i managed to make it 29540 after using it until 1% then shutdown. (almost 0%). the annoying thing here is: when my laptop battery full capacity stays at 26000, i used my laptop until 5% (about 1420mwh) surprisingly, it stays there until about 10minutes and start degrade to 4%. at 4% too, another 5minutes are spent on the 1020mwh capacity.freeze there. of course, when it reaches 3%, the battery capacity degrade steadily until 1%. the point here is, i know that the battery indicator should be inaccurate, that i can have 10mins at 5%, therefore i wish to ask people here whether they have any clue or solution to my problem.... i've read that some laptop such as IBM let users calibrate their battery via BIOS. i wish to do that too, since i found that my battery full capacity degrade rapidly unless i did the calibration myself again.... sorry for the bad english, and of course another common question being asked. i really thank you for reading my post and hopefully someone can share their opinion. once again. Thank You.
