New Zaurus Successor?

[Snappy]

I used to run linux in standby on teh thing till i had the drive resume problems, but do you guys get a ranbow effect show up on the screen for about 2 or 3 seconds on resume?

just wondering if the resume behavior between linux and windows is the same

btw suspend to disk works great still, its only suspend to ram. and unfortunattly i never got suspend to disk and ram working at the same time so taht if the battery does run out you can suspend from the drive

Which distro did u use? I might try ubuntu on it sometime ...

[Snappy]

If it does hibernation correctly, it should be as good as a shutdown, except that it stores an image of the system and sets a flag so that the startup sequence loads up the resume image to memory and move off from where it stopped instead of a fresh boot.

So everything should be turned off ... although some settings like "wakeup on lan" etc may and should drain power ...

I can see where it would use battery on standby, but not on hibernate, although mine seems like it might be doing that.
I'm running the original Windows XP on it.
I haven't had time to try Linux on it yet.

Also try this...
- Set the screen brightness at a setting lower than full brightness.
- Turn the unit off.
- Remove and replace the battery.
- Turn the unit back on.

What is the brightness setting now?
On mine, it always goes to full brightness.
This tells me the battery is used to maintain the brightness setting when turned off.
I wonder what else drains the battery that we're not aware of.

Left it in suspend mode after fully recharging it ... it dropped only 10% batt after five hours of suspend ... *grin*

Will have to try 12 hours suspend to see if it survive.

It should ... mine's gone 48 hours on suspend (though that was before I upgraded the RAM to 1 GB). The only time my SA1 gets turned off is disassembly and air travel

Fabulous! ... that is excellent news!

Just wondering out loud ...

1. Is it just my machine or setting, but is it that you can only have either the LCD or external monitor activated and not both together?

2. Any way to activate screen rotation without Portrait Pivot Pro?

3. Dial keys. Any way to install it to trial before buying them ... if it's possible at all?

i can see why the battery would drop on hibernate, most lose power over time.

the distro i am using is debian, give ubuntu a go if you want but i dont mind getting my hands a bit dirty (in fact i had ho to get suspend working, onec you know how its a one liner)

An interesting new entry coming up :
http://gizmodo.com/gadgets/breaking/oqo-ch...ller-265892.php

Very similar to the SA1 with some significant pluses :

- more powerful (VIA C7 1.2 Ghz) with similar autonomy (4.5 hrs)
- touch screen
- native Linux support
- price (600$ target)
- and above all, mainstream availability : distributed in Europe (by Packard Bell) and in the US. No more gray market and imports :-)

We'll see if and when this come true...

[gr8ful]

Interesting newcomer indeed.  I love the options that are starting to appear on the market.  In another few months I'm going to have a hard time choosing which platform will replace my C1000.

[fpp]

Yup. I'm all the happier to have my little SA1 (which I'm posting this on, connected through cell phone), to tide me over till next year :-)

Now that we are really spoilt for choices, does anyone know where a docking station can be found for the Kohjinsha?

[ZDevil]

Nice review of Kohjinsha II here!

[Da_Blitz]

for those not subscirbed to the kohjinsha mailing list here is some info i have come across, i may have also discovered a thing or two on the mobo anyway

Im currently running power tests on the device and very nicly asking the
battery for its power disipation (turns out acpi can be handy)

anyway attached are the power consumption figures including with the
wifi board removed (there is enough room for just about any usb wifi
card you can think of in there, im removing it and putting a Linux
friendly one in there)

Backlight Tests, Idle:
Backlight Min      480mW
Backlight 2        493mW
Backlight 3        509mW
Backlight 4        532mW
Backlight 5        561mW
Backlight 6        570mW
Backlight 7        586mW
Backlight Max      596mW

Full Load Tests:
* ls -laR / (hitting the drive)
Backlight Min 636mW
Backlight Min 766mW
* ls -laR /proc
Backlight Min 609mW


Idle Backlight Min:
Wifi On            482mW
Wifi Off           480mW
Wifi Removed       445mW

Bluetooth Off      440mW
Bluetooth On       460mW
Bluetooth Scanning 467mW

as you can see it appears the wifi card is in low power mode at all
times (i assumed as much, Linux noticed that its always present
regardless of the on/off state) but what is nice about it is the power
savings gained by removing it.

looking at a typical battery (and i assume thats what i have) we have a
capacity of 2530mWH, for an idle load with low backlight thats 5.27H (5
hours 16 Minutes). a 10mW saving represents 6 minutes battery life
approx. so by dropping the wifi module i have gained 24minutes battery life

thats fine for the moment as i am using Linux and at teh moment the wifi
card dosent work for me. this will soon change and i will have to redo
the tests, however its interesting to look at teh running time for the
backlight

Max: 5.27H
Min: 4.24H

so for an idle load i lose about an hour for maxing the backlight, under
load however things get worse

Max: 3.3h (766mW + 100mW (backlight, based of idle load))
Min: 2.9h (766mW + 100mW (backlight, based of idle load))

so a Hitting the drive while pegged at 100% with the backlight maxed out
vs low backlight, sitting idle not wirting to disk gives you an extra 2.37H

it seems that having bluetooth on reduces running time by about 12
Minutes, i have offset this with the wifi so i might just leave it on
all the time and set it up to connect using bluetooth to my phone for 3G
net access

don't worry this is drawing to a close

My next test will be posted in the next few days, it consists of several
parts.
* The effects of replacing the Hard drive with a CF card, both under
idle and full load (sustained read and write)
* The new tickless kernel
* If possible shutting down the external monitor out. after seeing a
talk on x.org and randr i have found out that some motherboards waste
alot of power on those sockets when its not even plugged in
* New handhelds.org power related stuff for shutting down the sound
CODEC when not in use
* Power usage when ethernet is disabled

have fun with those numbers, the only one i cant do is wifi related
power usage when wifi is active (and optionally transferring data)
because  i have not set up the driver

So are you saying you're dumping Kohjinsha and falling back on Zaurus?

I never gave up the Zaurus, I still have my C1000 and use it all the time.

very interesting. I will have to try some similar power saving techniques on my Sony TX2; interestingly, the physical switch DOES appear to disconnect the bluetooth adaptor.

BTW, I found that putting a bluetooth version 2 adaptor onto my linux firewall gave me MUCH faster internet browsing speed from my laptop than when using the older bt v1 adaptor... up from 256 kbps to 700+ kbps, and of course much lower power than wifi.

on the Z, using bluetooth to surf the net seemed only barely slower because the bottleneck is the Z's ability to render pages; that said, Angstrom and Minimo is quite snappy over wifi and I haven't got bluetooth working to compare it with

Surprised to hear your choice.
Not doubting you, but just wondering if you were referring to the screen in native 800x480 or 800x600 or the 1024x600 mode?

800x480 is crystal clear and definitely has larger fonts than c1000.

Granted I got the touch-screen version ...

*** I'm Selling My Kohjinsha ***

After much soul-searching I've decided to sell my Kohjinsha.
It's the black 40GB model and it's in mint condition.
It does NOT have a touch-screen.
I purchased it from Conics in March, so there's lots of warranty left on it.
I checked with Brett and he said the warranty would be transferrable to a new owner.

This is the email reply I received from Brett:

Hi Doug,

sure, no problem.

the warranty is on the hardware, not the owner.
(as long as the new owner mentions you if requesting warranty service)

regards,
-Brett

I have everything that came with it:
- AC Power supply for the USA.
- Battery
- The original box
- All the original books
- DVD with restoration archive and drivers
- Protective cover
- Warranty papers

Reasons for selling:
- The screen is really awesome, but the small fonts are hard for me to see.
- I hate the keyboard layout and feel.
- It's nowhere near as convenient to carry around as my Zaurus

I'm asking $750.00 which includes fully insured shipping by UPS to anywhere in the USA.
The only method of payment I am able to take is cashiers check or money order from a US bank or post office.

yeah the real killer is bluetooth 1.0 speed, my phone only has 1.0 and when i use it as a modem for teh kohjinsha i dont get the full speed (usb requires a kernel module from outside mainline)

what did you mean about the physical switch disconnecting bluetooth? i assume you ment that the button combo turns off the bluetooth modiule so it dosent draw power.

the one i am intrested in is if under windows the buttons turn off the wifi module and put it into low power mode, if it does then it may just be a firmware issue under linux preventing it from tuning off compleattly
