Okay this was rather ridiculous but I was told by a staff from one of the local retailers (won't be disclosed) that it doesn't support up to 24".

Anyway on with the more specific details:

It's a 24" BenQ LCD monitor which I'm connecting through Mini Display Port to DVI adaptor.. I'm connecting through a single-link Dvi-D. I've tested the LCD on other machines and it works fine (tried connecting with both DVI and VGA). My macbook is the Macbook Aluminium. The issue I'm currently facing is that the LCD is indicating that it is not receiving any signals and my macbook is not able to detect the display. I'm guessing its an issue with my macbook or the display adaptor.

I suggest you try with another screen with the same cable and adaptor. Have you tried that before? Your LCD might not compatible due to some reason. Mini Display port is still new for me. Yet to have much experimental with it, but so far VGA out to projectors seems working fine. Will check with some of my contacts that using one and see any issues.

biggrin.gif May I suggest you bring to the retail you bought it (if it's local). And test their ACD. Apple says MacBook unibody support up to 30" ACD.

If you're in Sg Buloh area, I can meet up with you to test as well.

Heh thanks, but I live in Subang and I bought the laptop from pavillion, hence the dilemma. Pretty tight on schedule lately, but I'll see what I can do. would maybe go on the weekend, or I'll pm you if I can make it to Sg Buloh.

I'm no Dr.

Can you tell us what type of HDD are they? Brand? Connection you using?
Is your MBP powered by adapter or battery when that happened?

Prompt you to shutdown meaning the gray color screen and everything freeze?

That's Kernel Panic. Run Disk Utility and check if the disk is fine. See if the external drive manufacturer provide softwares to boost cache speed. Manufacturer like WD provide such apps.

About my external display, took my laptop to a friend's house to test on his samsung t240... same problem. My sis is getting 2 adaptors for me to test from her work place (dvi and vga)... i just hope its the adaptor and not my laptop.

Any worse scenario you still have warranty. Now you know why its important to buy AppleCare.

MacBook Black cannot start up, only white light on and no respond (Help)

At 1st the flashing sleeping light, so i changed 2 brand new 1GB RAM and now no more flashing light but it just does not start. Might it be logic board failure?

So you got the original RAM with you

I want you to do a verbose startup. I assume that you still hear the chime. To do this , press Command + V

So its completely out ?

Tried resetting PMU and those stuff as per in apple site ?. Did you make sure that your rams are attached properly ?

If you have tried all the basic troubleshooting and still can't get it to boot up. Chances are you have messed up something !

Yup. I can only hear the superdrive's sound and white light.
Pretty sure the RAM is ok because the light flashing before I switch to another pair of RAM. And now the light is not flashing anymore.
Tried every possible way and stil can't boot it up.
