Allen, did u fill up the registration form and fax to 03-20940861 within 10 days of purchase? Said in newspaper, 3-yr warrant only valid upon registration.
I had a bad experience with Acer before.
Well, I am comparing this cq42 vs Asus K40 series vs Lenovo G460. Op System is optional. From pricing and warranty itself CQ42 wins.

So, will go for it tmrw.
How about gaming? Will it get extremely hot?

Well, I not bought this laptop for gaming.....as I dun gaming at all.

Bought it because of the pricing and warranty. Also the built quality, especially the keyboard

irontech, u did it yourself??

ya, cheap enough if compare to intel

ya, follow the disassemble service manual by HP

where to get the service manual? tq

@iRonTech : is it difficult to take apart the laptop? you use the paste on the gpu and cpu only? sorry for the questions.

here u go

http://h10032.www1.hp.com/ctg/Manual/c01531211.pdf

not difficult, just need patience as certain parts are tight. can't hard forced to avoid the cover plastic broken.

yes. cpu only can apply thermal paste, but the gpu original lousy glue replaced by 1 cent coin + thermal paste applied




now quite satisfied the temperature, it won't go high as previous, yet it cool down much faster (without any cool pad aid)


the heat shield for left palm rest place. it doesn't reduce much heat feel from top left palm rest place, but the HDD's temperature did go down faster than before also apply it beneath keyboard, I wanna make sure the fan flow go better & smooth.

material - aluminium foil

tqvm irontech.. thinking of doing what you did with my cq40-125ax.. warranty is over.. and the temperature is really-really hot

mine still under 2nd yr extended warranty period..really cannot stand the heat so mod em up. its much much more efficient than using those cool pad

guys... i have a new problem

my laptop screen seem to have horizontal Lines appearing...purple+white lines...it blinks...
the lines appear on the bottom of the screen.

is this gpu or screen problem?

@irontech: Thanks for the answers! 1 more question, the gpu paste. Did you apply it like this way --> paste, 1 cent coin, paste, gpu?

I'm gonna take it apart when holiday arrives! Can't stand the 100c temperature when both core are under load. even undervolting doesn't help much == perhaps now my tx2 can remedy that~

banks,

coin - thermal paste - GPU will do

u dun apply thermal paste on the the coin surface because u need the metal surface to become heat conductor, to radiate heat to the atmosphere. Apply a layer of thermal paste over there won't help.

ya, i applied both sides, different just gpu part less & coin to heat sink part more. its hd3200, so can't tell the actual temperature. if u guys using 3450, pls share the temperature b4 & after


By right should as what allenultra said, one side would do. but...haha... doesn't matter anymore one or both, as long solve the problem efficiency

story apply paste between GPU only & both sides coin:-

On the Pavilion TX1000 Nvidia blank screen issue, 5 weeks ago I applied paste just one side btw GPU & Coin, TX1000 awake from blank screen no response problem BUT only works out one week, went blank screen again. After heat up method the Nvidia GPU, applied both sides on the coin, the blank screen problem is working fine until now.

hi, i am from benq performance thread...saw this very interesting modding here, i might try it out sometime soon and share temperature drop

Added on April 20, 2010, 11:22 amjust wanna ask, did you do any lapping or cleaning on 1 cent?

This post has been edited by BBXiong: Apr 20 2010, 12:05 PM

no lapping as the gap size on cq40 doesn't allowed, you may do that if its allow, clean up yes

hmm..ok
i notice the thermal pad is the thinner type..dunno can fit a not..need to check out later on....

I have this problem before. Just sent it for warranty.

after sending for warranty does the problem reappear?
how long does it takes to fix this problem?

Hmm.....can't really say for sure. I've been using for around 5 months now after sending for warranty. So far there's no problem.

Around 2~3 days.

Result is 15 minutes of gaming in Guild Wars. Without TX-2 it will surely climb up to 90 degrees!
