Hi all, I want to request an unlocked bios and my second question is I have an urgent problem with my laptop under heavy load. I have looked all over the internet and I have cleaned my fan from dust and applied new thermal compound and I have a laptop cooler but when it is under load it quickly turns off because of some temperature optimization function in the bios. Is it possible to turn off this switch? My CPU is idle at 85°C and under load it is quickly at 95°C and higher. I believe 95°C is the critical temperature when the bios performs a thermal shutdown.
I would die for a unlocked bios! In case someone might find it helpful, I've wrote a Linux kernel module to control the fan speed, in fact the fan on this model is only capable of 2 speed on and off. Here is the file.
85c at idle is very high and dangerous temp ........... and its normal for this temp tp get to 95c easily .
controlling the fan will not lead to any thing useful as you should use a very good thermal compound and a new fan .
controlling the fan will be useful if something like 60c when idle but reach 90c easily ................... but 85c idle temp is very high and its a hardware problem .

You didn't understand me. I don't want to control the fan. I can do this already, and it's working. What I want to ask is it possible to raise the shutdown temperature a bit higher? I know this board has a big problem with heat. It's just a bad (and cheap) laptop. And about the temperature it's not exactly 85°C at idle it's about 75°C at idle and with some load it's quickly at 85°C. This is the range my kernel module can work for me, or when it's complete idle (means I'm not working with the laptop). But when I apply constantly load on the cpu, for example gaming, or pi calculations it get's hotter then 85°C and then it's shutdown. Don't tell me I have to use better compound or clean the dust. I already did it and I wrote it in my question.

Not all thermal compound suitable for laptop. Some thermal compound need under pressure to perform best. Heatsink on notebook doesn't put much pressure on the CPU. What is the brand of thermal compound you use? I already go through what you're experiencing right now. I also have re-applied thermal compound multiple time but it doesn't do any good until I found the suitable thermal compound for notebook.
It is possible to raise the shutdown/critical temperature but I don't think it will do any good. OK, right now max temp is 95C before system shutdown. Let say if we raise to 105C. I bet the temperature will continue to raise up to 105C & system will shutdown. Anyway >105C already dangerous & it will damage the CPU.
If you use my modified BIOS image & you like it, please consider making a donation. Thank you very much. Donate Here

Hi, I know it's possible, and I read this article about NVRAM and thermal reboot. I got some shutdown yesterday and it say critical temperature is 99°C when I reboot in Linux. Currently I'm using Arctic Cooler MX-3. I changed it a month ago. Maybe that's the problem? Before I was using Liquid Metal Pro and it gaves me very good result, but it's expensive and I wanted to try another compound. Arctic Cooler MX-3 is expensive, too, and I thought if I changed the compound and clean the dust on a monthly basis I can use a "less" good compound like Arctic Cooler MX-3? Currently I'm also limiting my max cpu freq to 80% say about 1900 Mhz from 2200 Mhz. This helps a lot but I think 95°C-99°C shutdown temperature is too low (for this notebook). I can need 5°C or even 10°C extra. What I like to raise is also the throtteling temperature of the cpu this seems to be exactly 95°C and this should be something like 105°C. Note that this temperature is for the BIOS only. I can switch the cpu to 115°C critical temperature withtout any problems, because normally thermal control is disabled.
Quote:HTC features enabled flag: true. Hardware Thermal Control is enabled.
HTC features currently active (means overheating): false
HTC features has been active (means overheated in past): false
HTC parameters are locked: false
HTC Slew control: by Tctl without Slew register
HTC Limit temperature (equal or above means overheating): 115
HTC Hysteresis temperature (equal or below means no more overheating) : 110
But this doesn't changed anything (or maybe I'm too dumb). I tried to undervolt my cpu, too. But it gives me instabality. Currently I'm using this config for gaming and Windows for both cores:
This is without undervolt but underclock and makes it possible to play some decent (graphic intense) games without a shutdown at lowest quality possible.
But it's the original not a better one. How can I replace this fan with another? I'm looking the internet, but this seems to be very risky a mod but less risky then the bios mod. What compound do you use? Can you give me an advise? Finally, I've also asked the vendor about this issue to no joy. I know I'm arrogant and I should get rid of this laptop because this is clearly a hardware error but thank you for your time anyway! The laptop has some good feature (AMD cpu, Raid, 17", Made in Germany).

I already tried MX-3 successor, Arctic MX-4. In review MX-4 is better than MX-3. However, what ever method I tried (pea, dot, single-line, X, etc) CPU will always idling at high 60s Celsius to 70s Celsius. I already lost count how many time I disassembled my notebook.
There are three thermal compounds recommended for notebook; IC Diamond 7 (ICD7), Arctic Silver 5 (AS5) & Shin-Etsu. Any Shin-Etsu are good. I use Shin-Etsu G751 & it works great. My CPU (with MX-4) usually idling at highest 60s Celsius to 70s Celsius & when gaming max temp up to 100C (sometime system shutdown too). After changing to Shin-Estu G751, it idling at 40s Celsius & when gaming max temp only up to 70C to 74C, no more. See, huge difference. I'd suggest try Shin-Etsu thermal compound first before trying modified BIOS. Shin-Etsu thermal compound not expensive. (Of course I have different CPU but my CPU is quad core. Quad core CPU does produced a lot of heat.)
To change the FAN, you'll need to disassembled the heatsink. The FAN is detachable by removing the screws. Not risky though.

This is the output of my kernel module when I just use the browser a bit. Right after Linux is booted the temperature is already 65°C and then it idle's about 75°C. This is when my kernel module control the fan and monitors the temperature. My main goal was to code a kernel module and to have a silent laptop when it's idle. This is done. The other problem is thermal shutdown and throtteling under high load. I would be glad if someone can raise the thermal shutdown and the thermal throttleing and unlock the bios for me. 65°C when just booted seems very high for me, too. Maybe I want to try this better compound (Shin-Etsu).

I'm new to thermal compound method and I found some Coollaboratory Liquid Metal Pad left so I dediced to experiment a bit. I re-applied a thin layer of Artic MX-3 and add a some metal pad on it. I hope this helps a bit, see my screenshot.
Here is a 80-Way Thermal Paste Benchmark. Shin-Etsu performs better then CoolLaboratory and MX-2!!!!

Can you tell me how to raise the temperature? I don't believe you.
