Something else you may want to try. I had an issue where I'd press the power button on my Inspiron N5010, the light would come on, then immediately go off. No POST, no Dell slash screen. I replaced the I/O board and same symptoms. Next I replaced the motherboard and the same symptoms occurred. I had already removed ram, CD, HDD, etc., and nothing. As a last ditch effort I removed the keyboard and plugged in a usb keyboard. And that my friends solved the issue in my case. Ordered a new keyboard, installed it, and everything appears to be working fine now. I wanted to post this just in case someone else has had the same issue and hadn't tried testing the keyboard.
