Non Booting Mac Troubleshooting Checklist

[Innes]

Hi guys

I've got a 630 that won't turn on. It sits on my desk in the warm and was last running quite happily maybe a month ago, playing some Diskworld.

So i'm just wondering what the things are to check, i'll open it up and have a look for any damage/bad caps and disconnect the clock battery, are there any other little things I can try that might help? Already tried a second keyboard, unfortunately it wasn't that

Cheers!

See if the 5V standby power are there.

I have seen failing power supplies in a few 630s now already.

Well i'v taken the pram out, inspected the logic board and pressed it's wee red button (all seems fine) and tried a different kettle lead to no avail, so i'm thinking it probably is the power supply. Bit of a shame, it gave no indications that it was on the blink
