OK . I've been doing a bit more digging . You need to remove the leg (not led) off that IC . Think it might be pin 10 . In the video I saw the guy used a couple of SMD diodes . I'll need to look at it once I eventually get round to doing the job to see how much space there is . The video I saw was in German . There's probably other ones out there that I haven't seen yet .

Thanks Chris . I saw another guy in a video (different PSU model) just remove the pin , without adding the diodes . Anyway . I'll use the diodes . I won't be able to start the work until the end of the year , but I'll post back once I have .

If you lift pin and leave not connected, OVP will be disabled. That's bad.

OK . Thanks . I'm assuming then that the 3 diodes in series will increase the cut off threshold by +2.1V ?

HP really didn't want people opening these things up , did they ? :lol:

Took me about 45 min just to get this far. Anyway. Now I need to get my x-ray specs on and mod the thing :thumbup:
