Battery Life Sure i Wish Had A Battery Life About Between 6-8 Hours Battery Life is Sure important Especially When On A Long international Flight And Would Like To Watch A Few DVD's

Lowering the screen brightness is the best path to better battery life. I've got the six-cell and I'm getting six plus hours of battery life with teh screen at 10/15.

Screen at 10/15 (2/3 brightness) is plenty bright, atleast for me.

4.6-5.2W idle, 10:53 (historic - web surfing) with a 97Whr 9-cell accomplished with a 12.5" HP 2560P. Uses the same QM67 chipset as a X220 with a i5-2540M, SF1222-based SSD and TN LCD set to 3 bars brightness. What software settings are required?

After doing a fresh Win7/64 install I set all devices set to maximum battery and loaded the Intel RST AHCI SATA driver. Then applied the power management reg hacks here under section 1. enable hidden settings “power options”.

The important ones being the reg hack to make visible the Harddisk AHCI Link Power Management. I set these options to HIPM+HIDM and 100ms respectively as shown below:



Then I altered the CPU management where can enable core parking, which I did for cores (3 HT get parked when on DC). I later found this was unnecessary as cores are set by default to park when not in use.

The important part is to set the maximum CPU % to 5% so it runs at the lowest VID. Then also install flashblock in Firefox so flash pages don't kick up cpu/iGPU utilization.

Very impressed by Intel's latest tech. I get the same or better battery life that my miserly L9xxx 2530P got. 22nm Ivy Bridge (IB) will improve things yet again. Appears socketed systems like a 2560P will be able to be upgraded to IB.

Cons - Buttonless touchpad may bother some users

How does this work without buttons?

If I wanted to right click and save as...how would that be done without buttons?

[vertigo_2_20]

There are 3 buttons (left and right click and a scroll button, which you press then move the TrackPoint around to scroll) directly above the touchpad. I still don't know why it's called buttonless. I personally don't even use the touchpad, in fact, I have it disabled. I just use the TrackPoint and the buttons.

OK...I'm used to using a mouse on my desktop and on my Dell Laptop I use a mouse...but I suppose I need to quit using a mouse on my laptop so I can get used to going mouse-less.

Been doing alot of reading on the ThinkPad X220 and I think this is the one I'm going to get as it's small, pretty fast, and it has a CD-Rom drive

How hard it it to add 4 more gigs of RAM?

A 12.5" X220 has no internal optical drive. A 12.5" HP 2560P does.
