Note: npapas means the 5th version that I sent him, not the one which I placed in my previous messages :smileyhappy:.

Here is the link to the latest version of my patch: Download.

 

UPDATE: I added CTRL-FN swap and disabled whitelist of wireless adapters. You can find this BIOS version here.

There are 7 temperature thresholds tables. I don't know which one is used in your laptop. Maybe each processor model has its own temperature table. So I leave temperature thresholds tables alone.

 

I edited fan speed tables. There are 6 speeds for the fan. We can change each speed the way we want. I lowered the first two speeds and now I need your feedback. Is it enough or I should lower the speeds once again.


 

Hi Middleton,

 

could you post the changes you applied to the fan speed tables? As I understand from your above post, you don't know about the threshold tables? So I assume you don't know exactly at which temperatures the fan speed changes?

 

Anyone else expirience with the modded BIOS?

 

greets and thanks to middleton for the effort!

I found the temperature thresholds tables, as I said above there are 7 tables. Which one of them is used depends on CPU model. How do you think what would be easier to modify: 2 fan speed tables or 7 thresholds tables?

 

As for fan speeds changes: compare the original BIOS and my mod. You'll see 10 differences. The first 5 are changes in the first fan speed table, the last 5 are changes in the second fan speed table.

Ok, but how do I compare? Which program to open? I'm not much of a programer and also don't know a lot about bios so excuse my asking...

This mod is beautiful; works like a charm.

 

And screw you, Lenovo, for leaving us hanging.

This is really good news. I will try the modded BIOS later this evening. Just have to put the fan back in first. :p
