Okay so I received this dead I-O awhile back and I just wanted a more condensed version of the troubleshooting tips.
Lets see here,
First off, the keyboard connector has 2 traces pulled up (looks like it was banged on the Keyboard connector)
Secondly, I already replaced the Bios chip with the original Bios from my orig. I-o.
Now Im not sure about CPU, ram, I'll wait for my old I-O to get back home so I can try swapping those. But as far as The Power supply goes, Can I get a refresher?
I know I have to test q16, q30, q34, q35, possibly q27, and q33, q25? I'll search for the values but can someone remind me?
Also, I tried the VGA-out connector as described in the tech ref. No image...so this may just be confined to the MB.(though, I'll test on good I-O) In fact Im sure of it since when I power up, all I get is a green light, then hold down to shut off (no backlight, display, etc.)
Suggestions, Helpful hints, Horror stories, all appreciated.
