my friends laptop (which has intel graphic) got the 4 times blink at boot.
since there are so many pages in this thread, i dont wanna read all of them.
this laptop can still be save or not? i dont mind doing some surgery to it.

according to chart, it seems like graphic controller itself not functional.

an article about the graphic controller

yea, it's not worth it to fix. don't end up like mine, just change the display for RM600+, then 2 month later mobo dead.

try re-seat ram

what kind of CPU u are looking?

my laptop cq-40 126au also gave me problem few days ago, keep blinking 1 time. thought the cpu burn or something like that. i was so frustrated that i whacked it few times with my palm at the bottom part where the proc is being positioned and immediately it BOOTED!!!yes u heard me right it BOOTED!!!lolz! well maybe anyone who had this problem can have a try too coz there's nothing to loose but so much to gain right?

LOL. I wouldn't dare to try that, sonic.

Hi there. I got some issue with my CQ40 screen. The screen become like have shadow when i open up the laptop. can anyone help me what is the problem.

my cq40..very hott...u guys know where to service? i think need to re-thermal paste proc..buang habuk

damn it damn it.
And damn you HP/Compaq for the crap design of the CQ40.

I got my CQ40-115AU in Oct. 2008, it used to overheat since then, I did use for not so heavy gaming at the beginning but no longer.
It used to freeze a lot on Windows 7 especially when playing flash videos or pretty much anything that makes use of the GPU. It also froze yesterday while running Ubuntu 11.04 (sign of GPU dying). My BIOS was already updated to the most recent version.
The extreme temperatures it reached can be very dangerous especially if its running on battery.

So minutes ago, it froze and refused to boot up (4 times of LEDs blinking >>> faulty GPU).


Update: I removed my HDD in preparation for back-up, but with the hdd removed I did plug the battery and it ran !!
I did the same test with AC adapter only and it ran as well. I finally plugged the HDD back in and the system booted just fine.


Update 2: the boot into ubuntu was fine. Upon restarting to windows 7 the laptop froze n i got the LED blinks. Hence i conclude that the sysyem did boot up in the beginning as the GPU had cooled down.


Update 3: the laptop resumed working, but as it was unreliable, I decided to open it up.
The fan had some dust, but frankly,, it was not clogged by hair or anything, I did clean it up.
The GPU looked intact, the thermal paste used it a dark purple rubber like material.
The CPU thermal paste looked bad, when I touched it , it felt like molten toothpaste and unlike high quality thermal pastes I've seen. It was also distributed unevenly over the heat sick surface area, so I redistributed it with my finger.
Assembling the whole this up was annoying, I got it back together but there were some excess screws.
Right now,, its running just fine on power saver mode in Windows 7 (professional 32bit, SP1), I also set the GPU power consumption setting to "maximize battery life".
The current temp with web browsing alone (no flash) is 51-52 degrees.



p.s. be careful when placing a hot or even warm laptop on your lap, it can damage your $stuff$ irrespective of the clothing.

how much to replace cq40 lcd? my screen got like yellow color and like dead pixel because falling from my sofa..

Guys any recomend repair centre at penang im not sure wht problem it keep blinking caplk and numlk (infinite) tried removed ram and reset 15sec on the power button hence the same problem happen ....

repairing CQ40 is not cost effective.
since right now u can buy new laptop which cost around rm1k and more better and faster than CQ40

furthermore, the exhaust fan for CQ in located at the back near the LCD panel. it make ur LCD lifespan short

My cq40 cant boot too after hybernating twice from win 7.. Led blinking 1 time.. Any chance for repairing it for 100-200 bucks?

Otherwise i'll disassemble and sell all the parts off..
