Battery “Last full charge” value decreasing in Thinkpad T42p

Standard

Posted on Ubuntu forums, getting desperate ;-)

Hey All,

Wonder if anyone could shed some light on this?

Since switching to Ubuntu, I’ve been through two standard batteries, and am onto another 9 cell extended battery, which is starting to show the same signs as the other two… after no more than 6 weeks of use. So I’m quite keen to get it sorted before it deteriorates too far, so that I can be as mobile as I’d like to be.

“Last full charge” decreasing aside, I should be getting 4+ hours with the extended battery, but if I’m lucky I get 3 to 3.5 hours – which is what I was getting on the 6 cell when my machine was still windoze.

Basically, the “Last full charge” just keeps decreasing, despite my attempts to keep it from doing so (including discharging fully, charging, discharging fully again), or keeping the battery withinn a charged zone…

Are there specific steps to take?
Are there specific settings that are advised, that are not standard?
Is this normal?
Is there anything I’m missing?

After much reading, these are the best resources I can find:

At the moment, this is what I’ve got setup:
installed cpufrequtils
installed laptop-mode-tools
installed pm-utils
installed hdparm

running cat /proc/sys/vm/laptop_mode shows a 2

laptop-mode.conf values are:
ENABLE_LAPTOP_MODE_ON_BATTERY=1
ENABLE_LAPTOP_MODE_ON_AC=0
ENABLE_LAPTOP_MODE_WHEN_LID_CLOSED=0

Anything else?

I’m pretty sure most folks get this, I’ve just got into the habit of checking my battery status ‘cos it’s decreasing so quickly, so I’m hoping that either someone knows what’s up, or there’s a few steps to take to stop this! Stop the insanity! ;-)

Anyways – thanks in advance ;-)

Nice way for Herman Miller to engage people with their brand…. posting it ‘cos I like the question of today – “how can we become better consumers?” – and kinda hoping they stick along those lines, and not sink to “how can we make better chairs?”…

Enjoy, some interesting (and brief which is good) reading… and immersive.

* caveat: 2.5 years ago I bought a Herman Miller Mirra chair (after seeing it used at my brothers BP office in Canary Wharf), and it has been one of my best investments ever…

Hummus is life

Standard

Since coming to Israel, I’ve eaten a fair bit of hummus, and I have to say it’s much better than the stuff we get in Londres… and Tahini is even better IMO. I’m really starting to enjoy it ;-)

Here’s some background for your reading pleasure:
_ Hummus – Wikipedia, the free encyclopedia
History of the ingredients

Chickpeas and sesame, the crops from which hummus’s main ingredients are taken, were known and cultivated in the ancient Mediterranean and Middle Eastern worlds. Chickpeas are hummus’s principal ingredient, and have been a human food item for over 10,000 years.[15] The chickpea was used as a food item in Palestine before 4000 BC, was one of the earliest crops cultivated in Mesopotamia and was a common street dish in ancient Rome;[12] indeed the famous Roman orator, Cicero, was named for an ancestor who had a wart on his nose shaped like a chickpea. Archeological evidence identifies chickpeas in the Sumerian diet before 2500 BC.[16] They are noted in a 13th century work by Muhammad ibn al-Hasan ibn Muhammad ibn al-Karim al Katab al Baghdadi of Persia for a “simple dish” of meat, pulses and spices.[17] It is unknown whether chickpeas were commonly mashed in any of these cultures. Tahini (sesame paste) likewise lacks any clear historical context. Sesame was grown as a crop in ancient Assyrian and Babylonian gardens and is mentioned by Columella.[18] It was common in Roman and Persian kitchens in the form of sesame oil but not as the tahini paste of hummus-bi-tahini.[19]

Other ingredients are used in sundry recipes of hummus-bi-tahini. The olive originated in Syria and Palestine, where it was being cultivated by the fourth millennium BC. A variety may have been indigenous to Crete, where olives were being cultivated by 2500 BC. The Bible mentions olive oil many times and it was exported from Palestine to places such as Egypt. Several Roman writers indicate that salt was used in extracting the oil.[20] Garlic was grown in the gardens of King Merodach-Baladan II of Babylon and probably was in Greece by the early Bronze Age.[21] The lemon was last to arrive in the Middle East and Mediterranean world, originating in India. However, depictions of lemons have been found at Pompeii and Tusculum, so this fruit must have reached the Roman world, at least as a luxury import, by the first century.[22]

Thanks Shmulik, Nimrod and Nils!

ubuntu /dev/sda1 full in system monitor; machine grinds to halt; basic properties say different

Standard

Just posted a thread in the Ubuntu forums:
http://ubuntuforums.org/showthread.php?p=6354500#post6354500

OK so last night I was doing an rsync backup, as you do on a Thursday evening, and rsync stalled saying something about not enough memory…

So I had a look at my filesystems (/ partition for OS; and /home partition for my stuff) and it says that /dev/sda1 is 100% full.

result is machine is grinding to a halt, and apps are shutting down…

df command in terminal says the same thing.

however, when i use “Properties” (right click on directory names) it shows the whole of / as only 5.2GB, on a 14.4 partition…

touch /forcefsk => doesn’t seem to have done anything:

http://ubuntuforums.org/archive/index.php/t-775653.html

i don’t seem to have any masive log files:

http://ubuntuforums.org/showthread.php?t=866445

googling for “/dev/sda1 full” doesn’t seem to yield much

so something is fishy methinks… and I’m wondering if any of the fine people here could help?

Anyone? ;-)

Good Sleeptracker experience

Standard

So I was at SxSW in Austin, Texas, earlier this year, where I heard Jason Fried talk well of the Sleeptracker watch… so I decided to get one since good sleep is something I’ve always battled to get more of, as well as waking up! ;-)

Anyways, point of the blog post is that last night it reported that I had an average of 30 mins between my almost awake moment, which is the most I’ve had so far…. and yes, I do feel like I’ve had a good sleep!
