Dear all sifus, Im having a A42J for almost 2 years already.. sent in for warranty last year, fan problem ...causing the laptop to overheat and restart...

Now i notice that it starts to get hotter like those days already, afraid the same fan problem. My question is:

1) whether we can manually detect the fan, see if it is working or not? any software to do so?

2) if no, can we just open the back casing and check the fan? well.. i nvr open a laptop casing before.. any guide to do so?

3) btw, is there any recommended temp. control or monitor software to help monitor the laptop temperature? what is the healthy temp. we need to maintain?

thanks a lot...

thanks for ur reply..

erm, the healthy temp u mentioned is referring to the processor temp,graphic card temp or hard disk temp?

i just used open hardware monitor and below are my readings:

Processor temp: 84C
Graphic Card temp: 73C
Hard Disk temp: 51C

im using for normal browsing... i guess it is overheated already.. what might be the cause?i think i can hear the fan sound, not really sure how to differentiate it with processor running sound... but got hot air coming out from the side vent...

thanks.. btw, what is the thermal paste? tml might try to open the casing following ur guide just now...

how to determine the thermal paste dry or not, need to replace new one?

hi sifu lee...

thanks for ur reply, now im facing another weird issue.. i have created a new post asking for help at Mobile Computing.. well, this is the case..


Whenever I restart my Asus A42JC laptop, it will automatically shutdown at approximately 15 seconds after the ASUS logo appearing. Then I try to switch on the laptop again, same thing happen, it just auto shutdown at the same timing---roughly 15 secs. I have tried to hit F8 and go to safe mode or last known good configuration... same thing happen, roughly 15 secs, no matter im on my way to Safe mode, or Last known good configuration, it shuts down..

Well, i need to wait around after 10 minutes, switch On the laptop again... then only it will go to windows 7 successfully.

VERY VERY weird... 1st time i encountered this problem. Other than that, it is working perfectly fine... ive been using it for roughly 7 hours already. Everything is ok, gaming...browsing...downloading...

Now I try to RESTART again... it went back to the 'auto shutdown' routine!!! LOL... meaning i cant restart my laptop~~~


Hope I didnt confuse u..

yeah... i tried this also... ON laptop, hit F2, go into BIOS, roughly same timing, shut down~~ ( I was randomly browsing some options inside BIOS) Any idea??

i checked at the website..bios version 216..updated 2011.06.28.. Yeah.. checked already, I am with the latest version

So what are u suspecting? Some people at LYN think is overheating, this came to my mind at 1st.. but not making sense as it only will shut down when i do a restart

yeah yeah... checked already my bios version.. the latest one..

yap, i tried also.. unplug everything... with only power cord (no battery), and with battery only... all scenarios also shut down..

yeah... following ur steps... discharged everything, then using power cord... auto shutdown... waited for 10 minutes, now only i can reply u

however, i tried checked my temp. now... CPU is 80C !!! but how come i din feel anything, not feeling any hotness... the fan is running at high fan perfectly.. bottom of my laptop oso cool.. how come processor temp. so high!?

is this the cause? any cure?

lee_what2004... problem solved, yeah.. i think is overheat issue.. i apply thermal paste dy.. no more auto shutdown... voila~~ thanks yeah..

Btw.. my asus came in Altec lansing speakers... but the volumn is damn low... i switched to maximum already.. sound still very low..

anyway i can tweak it? or configuration to boost up the volumn?
