If...Silly recommending the user to have to unplug. If this is a requirement of the battery than the battery software should cause a drain.<br /><br />Li-ion batteries will last longer if they are not charged a 100% and not drained to zero. For example keeping them between 80% and 20% charge. The software should have an option to prolong battery life and making the max charge 80% and max discharge 20%.<br />This will double the life of the batteries.Danielhttps://www.blogger.com/profile/03188833509564648560noreply@blogger.comtag:blogger.com,1999:blog-13386945.post-77914561623201629572010-12-16T08:04:22.582+02:002010-12-16T08:04:22.582+02:00Check my link on fsync, that will fix your problem...Check my <a href="http://linux-tipps.blogspot.com/2010/10/disabling-fsync-in-laptopmode.html" rel="nofollow">link on fsync</a>, that will fix your problem for all programs.D.https://www.blogger.com/profile/03544666801731533511noreply@blogger.comtag:blogger.com,1999:blog-13386945.post-92028521007376739172010-12-16T08:03:29.981+02:002010-12-16T08:03:29.981+02:00This comment has been removed by the author.D.https://www.blogger.com/profile/03544666801731533511noreply@blogger.comtag:blogger.com,1999:blog-13386945.post-12097445248468833202010-12-15T16:34:55.907+02:002010-12-15T16:34:55.907+02:00Why everybody forgets about HDD??
I have used an ...Why everybody forgets about HDD??<br /><br />I have used an Apple laptop for two week under Ubuntu 09.04 and the two most striking findings were: HDD runs hot, battery life is (bit less than) 2 hours instead of (bit more than) 4 hours.<br /><br />After manually removing the <i>redundant</i> pieces of software I was managing to get HDD to sleep sometimes and was able to squeeze about 3 hours out of the single battery charge.<br /><br />All over the net, people seem mistakenly forget and underrate that under Linux one of the major battery hogs is actually HDD. Under Mac OS X it remains cool and barely every spinning - while under Linux it runs hot and never sleeps: something always writes something to disk.<br /><br />P.S. I were using "pidstat -d" to analyze the issue.Ihar Filipauhttps://www.blogger.com/profile/05086565400407007423noreply@blogger.comtag:blogger.com,1999:blog-13386945.post-86548902905481482812010-12-13T06:58:30.573+02:002010-12-13T06:58:30.573+02:00> The most common problems related to suspend s...> The most common problems related to suspend seen in Ubuntu are related to the backlight or LCD staying on or the graphics chip getting wedged.<br /><br />There is more noticeable problem: then notebook can't resume after suspend.<br />For example, in 2.6.35 kernel branch and later branches detected regression with many notebooks, primary Samsung Nxxx series: https://bugzilla.kernel.org/show_bug.cgi?id=21952Юрий Чудновскийhttps://www.blogger.com/profile/13993625843248826527noreply@blogger.comtag:blogger.com,1999:blog-13386945.post-65517302912557913262010-12-13T04:44:48.037+02:002010-12-13T04:44:48.037+02:00To make things complicated, Li ion batteries last ...To make things complicated, Li ion batteries last much longer if they are kept partially charged rather than fully.
