Wierd shuttle sn45 problem?

Cyrus · 10 Aug 2006 at 11:26

i built a pc around an sn45 shuttle 2 years ago for my bros girlfriend. In the past few weeks a funny thing has happened. If you push the power switch it wont turn on straight away, but if you leave it for 5 minutes it turns on and then boots up?

Wtf could that be, psu on the way out?

could be psu, could check with a normal psu to make sure, also try swapping out the cmos battery.

Check wiring, try a different PSU and then try changing the CMOS battery.

what would be symptoms of a dicky cmos battery lads?

seems to be the CMOS i think. try a new PSu and if it doesnt sort it then its the CMOS.

ill try cmos first, no spare psu, plus its cheaper

wheres the cmos on the sn45 anyone know, she lives miles away rather she did it herself!

Common sn45 problem - most likely the PSU is dying. The capacitors often start to fail after a couple of years (sometimes you can even see that they've leaked if you take the PSU apart (usual PSU disassembly warnings, etc). So when you power on, it sits there slowly charging its increasingly ineffective capacitors, and when they've got enough juice to actually start the system, it springs to life. I fixed mine simply by using another PSU - external in my case, as I didn't want to pay the extortionate fee for a crappy 250w thing..

Psu, has to be....

What motherboard revision was this shuttle (if you can remember)
the version 2's had the vdimm problem which could kill a shuttle stone dead
