Can not switch on my Macbook Pro
at first when this happen, i would press and hold the power button and force shut down the computer then when i press the power button again my MBP will turn on normally. But this kept getting worse, now the aforementioned will happen for more than 30 times before i can eventually turn on the computer. i've tried the resetting PRAM thing and read the display article but none of them mentioned the sleep indicator flashing three times. i don't know what might have triggered this.
Recently I've installed 4GB memory to my MBP, (replacing the 2 1GB memory). But i have checked the specification and the speed of the Ram and all that stuff are suitable for MBP. Have anyone experienced this before please let me know what's your opinion on this.
Macbook Pro 15" the middle class one., Mac OS X (10.5.3)
