Dont know, but I rather have the fan died first rather than any part of my lappy, especially the GPU and CPU

Newsflash! I bought a few resistor at Jalan Pasar today after Friday prayer to lower the fan voltage, lower voltage = lower speed if you dont know.

I found 10 ohm is enough to make it quiet, but its still a bit slower than I wanted so I parallel 10 ohm with 20 ohm resistor to get 6.67 ohm and now the voltage is 3.89V instead of 5.09V (the onboard fan connector is somewhere at 1.XXV region if I remember correctly). Even with single 10 ohm is a lot faster than onboard fan voltage

Picture of the paralled resistor on the lappy, a bit messy since I dont cut the extra legs, but its ok as long as its not shorted somehwere, I use cello tape

No, you should read where I 'from'
<----
I have little background in electronics, but I like to discover things and from year 2007 I 'discovered' audiophilia and learn electronics from there, from not knowing what are opamp, now I can create my own circuits for analog out of my soundcard

This is basic electronics, just a resistor to limit the voltage and apply Ohm's Law but the fan dont have any sticker about how much amps it uses I just guess the value, resistor at Jalan Pasar for 1/4W is 10cent each . Everyone at least knows this, its just a matter to do or not to do

I use multimeter to measure the voltage. I dont do the math, I just bought the resistor by instinct Its not pasar malam, its jalan pasar Everything is my experiment, I learn stuff by practice, you should see what have I done to my soundcard, graphics card and headphones

Some of my stuff, my headphones, and my old 9600XT graphics card

You can bought at any shop, I bought at Darson

EDIT: My final fan mod, its unbelivably tidy, I put the resistor on top of the wireless card but I put some tapes to prevent it make a contact and put a piece of paper to prevent it from shorting with the backpanel aluminium foil

That thing uses Athlon Neo, for extended battery life but of course lower performance, k40AB is way better. Weird, if they wanted to use low voltage CPU for more battery life why use HD4570 GPU? What is this laptop for when k40AB is here?

What kind of effect? What can it do to the chipset? I never put the sidepanel on my desktop, it works well for few years now, so why not on a laptop?

Dust? I clean it regularly, my desktop once each month, my laptop hasnt clog up with much dust yet surprisingly even I open it up almost all the time, but I just use cotton bud to clean the heatsink and the fan. Other thing is, clean your room regularly and the dust wont be a problem

Guys please keep this thread clean, dont post anything not related to k40AB/k50AB. If you want laptop recommendation, go to recommendation thread, discuss there

EDIT: Another of my mod of the day, I open the HSF. Its easier than I thought but it voids the warranty, but I rather have the warranty be voided than overheated laptop. I found a bit of dust bunnies inside the fins, temperature drop further about 2C in load.

And an interesting I found is, there are actually TWO set of heatsinks on it, the one is the heatpipe to the back heatsink fins, that cools the CPU while the other one is just one big flat piece of aluminium without any fins whatsoever and its just connected to the main heatpipe via small patch of thermal paste, and this cools the HD 4570 GPU and the main chipset! No wonder the idle temperature is so high! I plan to buy the small RAM copper heatsink to increase surface area and further cools the GPU

Well, I'm not putting it on fire, why should it burn in the first place?

I rather have the battery to be unplugged when fully charged, because I notice if I kept the battery in and playing games it got slightly hotter than without. Yes it didnt charge the battery but the circuit is still on and it will monitor the battery status ready for charging

You should rephrase that question, how can you charge if its not connected?

This is my own way to maintain and use battery:

1) If you use it at home and not move regularly, remove the battery after full charging even though its not charging, the battery DO get hot even if its not charging (this is from my own test)
2) If you want your battery to have a longer lifespan, use it at least half its capacity at least one a months. Lithium ion battery dont need full drain
3) If you plan to not use the battery at all (for some unknown reason, maybe a backup battery) charge the battery till around 40-50%, remove it and keep it at the cool place

No problem And thanks for telling the update of the new driver on ASUS site.

For anyone who want a louder onboard speaker, you dont need to use SRS anymore. I just use VIA HD Audio Deck equalizer to make it louder, lower the 60Hz and 170Hz a few notches around 10-15 and other frequencies higher to about 23-25, it will make it louder without clipping (dont enable Loudness Equalization)

The driver is just that, a driver to drive hardware. What's the use of new driver? Adding optimisation for new games, to increase perfromance, bugfixes etc

Please dont ask this kind of question again

I have that kind of weird problem too, but what I did is open up task manager, end the program processes and then run it again, and it works. No idea why, but I'll need to change to 7 x64 when I got another 1GB RAM

Dont be lazy again, read the first post

Yup me too, it didnt install the HD4570 driver, just HD3200. And when I manually install HD4570 driver after next reboot it gone and only HD3200 is displayed

After this I run dGPU again to gain extra RAM for GTAIV

Windows XP dont support PowerXpress. Change to Vista or 7 if you want to use it

Never use V3000 Compaq but this laptop is definitely cool to touch no matter what you do, what you play, even when overclocked. Worth it? Of course, especially for gaming

I just patched GTAIV, it works very well indeed, way smoother than before but the resolution is 1024x600

No. The resolution is of course in game, the desktop is 1366x768
