W520 low WEI score, & poor performance

Recently I bought a used Thinkpad W520 model:4284cv4 from Ebay.
What the problem I am encountering is about the low performance this W520 laptop performs. I have also the X200 on hands, it looks like the performance is even better with SSD for both laptops.
I am disappointed because I suppose this is the best laptop in the world with the best keyboard.
You can see that the WEI score for processor is very very low, 4.9 only.
It's unbelievable anyway. It should be above 7 or more!!! Smiley Frustrated
I also check the ways to optimize the WEI score on this forum but it doesn't give a help for my laptop.

I found that the CPU loading is very easy to raise up to almost 100%.

Can anymore one here to do a favour for me in the last day of 2014????

Re: W520 low WEI score, & poor performance

I had the same experience with my W510. Please refer to the follow threads:

 

Lenovo Community

Microsoft Answers

 

There is somethign particular to the WEI analysis that it does not enable TurboBoost or SpeedStep technologies available to the processor; at least not in my case. I monitored the processor during the WEI analysis and the processor clock was supressed to it's minimum 930MHz core speed (native 1.6GHz, and 2.8GHz TurboBoost) on all four cores for all tests.

 

My solution was to clear all the prior analysis (see the Microsoft link), and to then install and run Throttlestop before starting a fresh WEI analysis. This prevents WEI from throttleing back the processor. I went from a processor index score of 4.8 to 6.9.

 

Once I was done the analysis, I uninstalled Throttlestop -- or simply quit using it. I had run other analysis to demonstrate in day to day use, the system and applications were accessing the processor technologies, and everything was working as it was supposed too.

I have the same CPU (2720QM) and I get a 7.5 WEI processor score without using having to use throttlestop. Make sure all your power settings are set to maximum and that your laptop is plugged in when running WEI.

Double-check your power profile settings; they might be misconfigured.

I'm also getting 7.5 CPU WEI on the 2720QM.

Unfortunately, I did what you mentioned, it doesn't work anway. The score is same exactly even I had deleted the provious record.

Do you mean the "system cooling policy"? It's active for my setting. Every setting is at the maximum performance. What's your setting at the BIOS? I want to have a comparison.

Re: W520 low WEI score, & poor performance

I have it set to Maximize Performance on AC power in BIOS (I assume you're running the WEI on AC power?)
Also, do you have a battery installed in the system?

Furthermore, the power profile itself can sometimes bug out, which effectively disables turbo until you do the following:
1. Go into Lenovo Power Manager, Advanced mode.
2. Choose your power profile.
3. Under CPU speed on AC power, set this to Balanced.
4. Hit Apply.
5. Set it to Maximum Turbo, hit Apply.
6. (Optional) Set it back to Balanced, so the CPU can clock down when idle.
