Yeah not even done tweaking and I have no special programs or voltage altering. I was web surfing with 2 SSH sessions running and the calculator. Seems I average between 7.6 and 8.6. Loving this x200s more and more!

No need to show off I'm getting about 16 watts average.
-
Have you tried tweaking the power manager settings to see if you can get lower usage? I would assume the i series t series could get a lower wattage drain then that. But then again I have been wrong.
-
wow!
@sphinx - a slightly OT question. Please feel free to answer here or via PM.
I'm thinking of switching over to linux as my mainstream desktop. How easy (or difficult) is it to migrate from a version of linux to the next? Are the user preferences and data taken care of? Any pointers would be of great help! -
Wow, I have 14-25 wats on my T410 all the time.
Lucky you ! -
The same x200s with Vista 32 & 4GB & SSD & Brightness 6:
- 9W when browsing via ethernet
- 13W when streaming a flash video in the active tab (10-11W if in the background)
-
As far as migrating over you'll have to start from scratch with settings. But that is the fun of it as linux has such applications as compiz where you can creat a desktop cube. Data you can copy over as long as you have applications that can use it and it works on the file system.
Again easy and fun switch, just depends on your needs.

Your reincarnation into an Thinkpad enthusiast is complete, welcome to the Thinkpadder club...
So are you going to get a DIY Vidock or something? -
I was thinking about X200s myself, but realised that with WXGA+ its out of my price-performance range, SL CPU series arent powerful enough for what I need my laptop.
Then I was considering X201s somewhere in the nearest future, but again, way too pricey for WXGA+, also WXGA+ is very rare and probably wont be available brand new when I could afford it. Otherwise i7 LM CPU in X201s seems like good CPU for such ultraportable with great battey life.
I do hope that Sandy Bridge will turn out to be great performer with excellent battery life and cool running temp's, unline overhyped Arrandale -
I can get down to 8 with wifi on and brightness 5 on the T510, and it averages 12-13 say with light webbrowsing. Arrandale likes to jump up to high teens for wattage, which penryn does not do, but still, I think getting something like 14-25 watts on a T410 is high.
-
7.5 W with the X200s is... well... you can do better.
5.7 W is the lowest I've seen. -
The i series is great on performance, but I wasnt a fan of the heat an power efficiency when I switched to my XPS. Sure I could power through anything, but my wrists were warm when using the XPS at its limit and I couldnt get much battery life out of it. But then again it was a workstation. 3.5-4.5 hours out of a discrete gpu + quad core cpu and all the other options isnt bad, but its far from what I wanted and needed. I really hope 2012 brings the i series past the c2d series on battery life and they run as cool or cooler. ::crosses fingers::
-
Wow, 7-9 watt is a really nice low watt number for internet surfing.
My x120e which is a zacate platform uses 7 - 8 watt on idle. 10 - 15 watt when surfing internet.
How about watching a mp4 movie? 640*480 resolution movie uses 12.24 watt. With a 32 wh battery, I only get about 2.5 hours movie time. -
-
-
Slightly OT:
* what's the fan activity on those things when they are <10W?
* are there any Thinpads (X-series I guess) without a fan? -
Both of my thinkpads are dead silent. I'm assuming low or off, but then again I wouldn't even know if my fan failed they run so quiet.
-
-
You got me curious, so I tested my X201 in Ubuntu. With screen brightness turned to the lowest, WLAN radios off, I average 12.5, with an occasional dip to 11.9 watts. Running the way I normally use it, 3/4ths brightness, wlan on, multiple programs running, I'm seeing about 13-15 watts. That's still enough for close to 7 hours of battery life on the 9 cell, so I can't complain much.
-
Well I found out my battery is at 66% and Im still getting 7-8 hours or more. Little upset, but thats what you get with used computers. Adding 9 cell to my list of todo's for this machine.

I don't know if it matters or not, but what is the res on this? Is it the stock 1280 x 800 or the 1440 x 900?
-
Res is 1440x900 based on the screenshot.
What wireless cards are you guys using? My Intel 5100 lights itself on fire when I used Ubuntu 10.04 and 10.10 on my x200s. Powertop did not fix the problem. Any advice? -
Jayayess1190 Waiting on Intel Cannonlake
-
My x200s has a 1280x800 screen (and webcam)
-
-
You might want to double check that power saving is on for your card though -- powertop won't suggest it for the newer cards IIRC, so you'd have to do it yourself. -
Thanks guys for the confirmation.
Sphinx, you say it made your transition FROM t400 very easy..... Did you not find the 1440 x 900 to be too small on the 12.1 from the 14.1 1400 x 900 on the t400?
Boy that's a mouthful
Thanks! -
-
Boy, I wish. Though they seem to be going the wrong way.. The x220 they are coming out with is only 1366 x 768! Someone over at Lenovo needs to be slapped!
Seems if you want a higher res, you have to keep going back to the older models. It's a shame.
Since you seem to be a higher res guy. Would you say you prefer 1400 x 1050 4:3 12.1 screen or the 1440x900 16:10 12.1 screen?
I guess it may also depend on what kind of work you do....... I prefer the former because I"m a web developer / programmer, and like the higher vertical res.
But I'm curious which one do you find more comfortable to work with? This is provided you have used a 1400 x 1050 screen in the past.
Thanks! -
The reason I said it would matter on the keyboard is that 4:3 12in laptops have a squished or compact keyboard when compared to 16:10 laptops. While 4:3 resolutions were higher, getting an x series meant dealing with a smaller then normal keyboard which is tied for the most important feature for computing professionals. The keyboard in my x200s is the exact same as my t400 and thus perfect for all day computing without adjustment to and from a larger thinkpad. But again if all else stayed the same yes I would take as much top to bottom pixels I can get. Hence why I went from a 2010 XPS to a 2008 x200s. Much much smaller computer but pretty close to the vertical resolution I had in the XPS. -
Oh and BTW I was writing a very basic process script and surfing and got down to 7.3w without adjustments. For some reason I had to edit this one in gimp to upload. Sorry if its too small.

Point about the keyboard is well taken! You are absolutely right. With the 4:3 layout, you don't get the full keyboard. That's a nice to have.
I'm glad you agree that 4:3 layout makes more sense. And yes, it's a frekin' laptop not a dvd player... For the love of thinkpads!!!
This really helps though Sphinx. I'll be scouring ebay for an x200s with 1440x900. Or an x61 with 1400 x 1050. I think I'll be happy with either.
Am going to hold off on the x220. Maybe they'll get IPS screens for the t series and come out with a nice 14 inch 1440 x 900 or 1600 x 900 for a t4xx <insert drooling image here!>

7.3!! Jeez!
Talk about sipping!! So, that batt must last you like 8+ hours? Essentially you are going a full day on one charge? -

Comparative: Win7 maximized battery life on SL9400-1.86 2530P per sig
My DC profile is as follows:
1. brightness set to 3 bars
2. wifi 'power transmit' set to 5. Highest. Ad-Hoc 5100AGN power management set to "maximum savings"
3. Run [email protected] undervolted with Throttlestop by use "DCExitTime/ExitTime" so TS exists once it's set this up to reduce monitoring load.
4. Set 4500MHD graphics to "maximum power savings"
5. BIOS has LAN disabled
6. Intel RST drivers for Win7 - uses AHCI Link Power State Management to improve battery life.
With this DC profile my system idles at 5.0W (!!) wifi on three bars but idle. This is very impressive. My 52Whr 6-cell is lasting 7:43hrs as confirmed by batterybar. If I had a 93Whr 9-cell battery then I'd be getting 13:50 of real battery life.
I find Ubuntu doesn't idle as low as WIn7 though I've seen it in the mid 6W without doing any optimizations. -
Wow, thanks for sharing!
Didnt know that such impressive results can be achieved with more tweaking!
You dont find such threads with info how to extend battery life here except for Power Manager settings and BIOS port and feature tweaks.
BTW, that driver link doesnt work - 404. -

Also what is the minimum you guys are getting on Ubuntu with the x200s then.
We should be doing 0 brightness, 0 activity, wi-fi on but idle to really be able to compare across OS's shouldn't we -
So I was using my T510, reading a PDF document on google chrome (a really light workload), and saw a minimum wattage of 7.8 or so. This was at brightness 5. So it should be possible to reach even lower with a T410 or with a low voltage x201 series.
Webbrowsing can really eat up your battery life; flash websites are killer. Once I go onto more flash heavy sites, the battery life remaining drops dramatically. -
-
-
Although I do remember the lowest I could get my x200s under Ubuntu was around 8W and that was dead idle. Right now in W7, with a single browser tab and Word open, 9/15 brightness, I'm at 6W. -

A small update to my previous post. I originally found the Intel Rapid Storage Drivers lowered my Win7 idle power by 0.6-0.8W. However, this was accompanied by startup BSOD 0x7B so was not a solution.
After some trial-and-error I found I could get the same power savings with the standard Microsoft driver by setting "Attribute=1" in the following Balanced Power registry keys. This then revealed AHCI Link Power Management in Power-> [Plan]->Advanced->Harddisks. I set these options to HIPM+HIDM and 100ms respectively.
Code:HKEY_LOCAL_MACHINE\SYSTEM\ControlSet\Control\Power\PowerSettings\0012ee47-9041-4b5d-9b77-535fba8b1442\0b2d69d7-a2a1-449c-9680-f91c70521c60 HKEY_LOCAL_MACHINE\SYSTEM\ControlSet\Control\Power\PowerSettings\0012ee47-9041-4b5d-9b77-535fba8b1442\dab60367-53fe-4fbc-825e-521d069d2456

That seems interesting!
Could you tell me if both of your X200s are dead silent in light web browsing (no Flash) scenario? And are they getting noisy once playing a Flash movie?
Or when playing a HD 1080p vid?
I've read that fan management didn't used to work very well under Linux with these Laptops resulting in a noisy fan spinning constantly, so I want to know if it's still the case with actual GNU/Linux distros!
