Battery “Last full charge” value decreasing in Thinkpad T42p

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.

Hummus is life

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

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

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!

Checkout Grooveshark

So I’m in Tel Aviv, working at MyHeritage HQ, and Nils puts on some tunes from a site called Grooveshark. So I asked why he wasn’t using Spotify (he’s a Swede you see) and he says it’s something about tracking IP addresses for ad revenue (which I can understand, but people move their computers, right?), so he’s trying Grooveshark out and it’s workig pretty well…
_ Grooveshark — About

Music compels all of us–individually, in our own way. It fills our moments, our cars, our movies, and our thoughts. Grooveshark started with one question: how could we be enriched by changing the way we find and listen to music?

Our goals: To improve the connection between people and music. To change the music industry in ways they seem so unwilling to consider. To have fun.

We have a team of 40 passionate employees who wake up daily to live and work for the music, but what we’re really about is simple: you. We want you to help us grow, get better, and help us help the music. It’s the one thing we can all agree on.

Why I’m blogging it? Well, it’s a good looking site, with a clear purpose and vision, and easy to use, and it fills me with joy… along with Last.fm.

On a side note, apparently there’s this thing called the internet, where people talk to each other from all over the world… go figure Mr Music Label Executive…

Oh, and one other thing which I found funny from their site (see if you can find it):

Skype sound / audio problems on Ubuntu 8.10, with Thinkpad T42p

So recently I upgraded to Ubuntu Intrepid Ibex, which I’ve found to be a real improvement (but that’s another story), and then I installed the newer version of Skype which supports video.

Chat works fine, but I ran into a few problems with voice initially, so left it awhile, but today needed video, so decided to sort it out once and for all.

This is the forum post that helped me, although it wasn’t the exact solution so much as fiddling with things through trial and error that helped:
Sound Problems with Ubuntu 8.04 - Skype Community.

So my solution was:

  1. fiddle with the Ubuntu sound recorder, using the volume control utility open to get the sound mixing right - use an mp3 format to get output right in the sound recorder - to make sure you can record something.
  2. once you have that working, go to Options > Sound devices in Skype, to select the correct sound device to use. I had to trial and error each of the sound devices for Sound In to get it to work (was not the default driver - look for Intel 82801 DB-ICH4 (hw:182801 DBICH4,0) ); set Sound Out and Ringing as pulse which worked fine.
  3. click “apply”
  4. try a call and see what happens; if not, rinse and repeat

et voila, it worked for me….

Hope that helps ;-)

Read: The King of Green Investing

As a biologist, zoologist, entrepreneur and techie, this article makes me think we have a fighting chance… incremental changes increase productivity or output, but they don’t make quantum leaps of progress needed to solve some of the real problems of our time, IMHO. Hopefully Vinod and the work he’s doing will affect some of that…

Making cement without also making carbon dioxide seems impossible; the basic chemistry of the process releases the gas. But maybe that’s not really true, Stanford University scientist Brent Contstantz began thinking last year. Of course, it was only a theory, he told himself, but the market for cement is so large — about $13 billion annually in the United States alone — and the pressure to reduce its effect on the environment so strong that he sent a 12- line email to venture capitalist Vinod Khosla.

“I have an idea for a new sustainable cement,” Contstantz wrote. “I’m sure you are already aware that for every ton of [standard] Portland cement produced, approximately one ton of carbon dioxide is released into the atmosphere. My cement wouldn’t do that; in fact, it would remove a ton of carbon dioxide from the environment for every ton of cement produced.”

Khosla, who knew Contstantz only casually — the two hadn’t been in touch for 20 years — was on vacation. But after a discussion that lasted only an hour, he told the scientist, “I don’t care about the rest of the business plan. You don’t need to estimate costs. You don’t need to do a cash flow. You don’t need to do a presentation. Just hire five people, set up a lab, and go.”

Contstantz was astonished. “What we’re up to,” he warned, “takes balls.”

“Well, you’ve got the money now,” was the response. “Get busy.”
