well before i undervolted the cpu battery life for me was 2 hours and 10 minutes. After undervolting i managed to squeeze another 25 minutes out of it, which is good! (credits to Najmods) and the heat went down too by around 8 to 10 degrees. when under load the voice emission is not noticeable, fan speed is pretty low so yeah, its perfect for classrooms and quiet ebviroments. hope that helps!

Great, thanks for your information
The heat doesn't really concern too much to me compare to loud fan noise, as I hv been use to it already on my rig



Out of topic:
Anybody here can clarify whether what this guy say is true or just bull? According to him, it's ok to run your processor at 100'C as long as it's within the thermal specification of the cpu.

The fan is very quiet when running normally, and it only spin up if it reaches 80C and up IIRC

Regarding the thermals, that guy got a point. CPU are made with different process, different amount of transistor and there is A LOT of variable that we don't know, so it varies between CPU. I'll read more regarding the topic and will post what I found here.

EDIT: From this page the maximum operating temperature is 100C

No problem I'll put that info on the first page for future reference. I never use the battery for more than few minutes because I don't like to use them

ive tried to find this laptop but kinda rare and only a few people selling it at lyn. care to share where did u get this awhsum lappy?

Hey TS, is there an ASUS programme to manually set fan speed? and can give WEI score, GPU/CPU temperature screenie.... sorry ah, i ask so much XPP thanks thanks...

Lowyat Plaza of course, hunt around, you'll find it, ask the exact model, if they look puzzled, leave immediately, they don't know it

There are no program to set its fan speed, I'll check again if its in the driver CD, WEI score and temperature on the first post, read it carefully. Maybe others can do the screenies on temperature, I never run the laptop with back cover unless it is really necessary

Hello guys,

I just bought this laptop (ASUS K40AB). Yes the sticker does display ATI RADEON HD 4570.
I've updated with the latest driver.
I checked using GPU-Z, Windows Properties, ATI Catalyst, it says HD 3200.
I've checked using a lot of things but it says my graphics is HD 3200.
What is the problem? Or am I being cheated?

Thanks.

Maybe it's Advancd PowerPlay come into play, try check your CCC and see if you can change to using the discrete card.








#Najmod, can you do me a favour and check how are the 4570 temps in your lappies? does it get as high as the cpu? Sorry for the trouble

I just got my K40ab from PC City in Kuching last week. Selling price at RM1999 and I add on another 2gb of ram which cost another RM85.

The laptop itself comes with a beg and a mouse other then the laptop and the power cable. PC City was kind enough to throw in a bunch of free gift - notebook cooler, another mouse, lcd protector, lcd cleaner, usb 4-ports hub and keyboard protector. The LCD protector given to me was a 14.4" but can't fit the K40ab cause K40ab screen ratio is 16:9...HD size I suppose. So if you are buying LCD screen protector, do take note of that.




I have a hard time get the HD4570 to show up also, tried a few drivers and it still don't work. CCC 4.5 will make it show up but it some how become extended monitor and I can in no way make it right. But at last I installed driver from ASUS international website and it is working fine. You can switch it with the power express thingy!
ASUS K40ab VGA DRIVER

Hope this little bit does give you some help!

So finally you decide to get this k40ab Congrats on your new lappies!!!
How are the operating temps for you? If you feel it's too hot, you could try to downvolt it, and remebr to enable CnQ as well.
Cheers

Haha, yeah been doing my research on laptop quite long and this is my final decision! haha, what is CnQ? really wanted to downvolt it, but a little scared...grrr...

hey thanks a lot. I'm downloading it now. I'll reply the results later

You welcome! sharing is caring!

CnQ=Cool n Quite, it would downclock your cpu when it's idle, hence use less power and less heat also. Use CPUz and check if your clock speed keep throttling or not.
About the undervolt, a lot of people been doing it and no problem, it's working great for my brisbane too, just be careful and you would be fine.

Haha, I am very lost now. So how should I enable the CnQ? Guide me if you don't mind?

Btw, I just call PC-City recently, and they tell me that k50ab would prolly release after 1-2 weeks or around the PC fair, I"m eagerly waiting for it
Since they give you so many freebies, I would sure *ugut* from them too

Haha, you should, you should! you from Kuching?

Go to your power setting or something like that, tick the Balanced Power plan, check your cpuz and see if your clock-speed went up and down. If it does, then it's on, then you could tweak the voltage with K10stat or RMclock.

There are no thermal sensor on the GPU

HAha, I'm from KK, can count neighbour also la Borneo
I check and find-out only PC-City is selling ASUS laptop in Sabah, maybe it's branch of the Kuching company gua
