X220 WEI of 6.3 [ Edited ]

[JNavas]

Just a clean Win7 OS install on my X220, and my WEI score is now 6.3:

(This is first try after boot on the 65W adapter with charged battery installed.)

What was it before?

6.1 (on 65W adapter with charged battery installed).

(6.4 on 90W adapter.)

Hmm. Mine has always been 6.3 on 65w adapter since one of the intel driver releases improved the performance.

Have new drivers come out?

I have a WEI 5.9 with the Hitachi 350GB 7200rpm.

I'm expecting that to improve to about 6.4 when I install the Samsung 830.

Same here. I'm running the factory Lenovo software (not a clean OS install).

The difference (for me at least) is that in the past, it would take more than one try at WEI to get 6.3

on the 65W adapter -- the first try after boot would usually be 6.1, whereas now I'm seeing 6.3 the

first try. (WEI has small side effects that persist from run to run.)
