Shuttle SN41G2

[jp7]

Hello everyone. I have an (old) Shuttle SN41G2 that works just fine once On. Lately, the machine has been taking longer and longer to turn itself On once I press the Power Switch. At this stage, it does not even turn itself On after any reasonable amount of time.

Does anyone know which electrical part may need fixing/replacing?

I have an SN45G (oldskool V1 ) and it's having boot troubles as well. My problem I think is the little battery on the motherboard is dead, so it doesn't hold the bios settings. Its meant to be a media pc and is switched off at the socket along with the tv and amp so the old battery can't cope with being used for 12+ hours at a time. It isn't at all happy with the default setting either as it's an Athlon XP-M hence doesn't detect normally, and there's no keyboard in so helpfully says something along the lines of:

"Error - no keboard present, press F1 to continue"...
(end of sidestory)

So it could be the battery if you bios settings are causing trouble and it's having to detect the hardware by default. The only other thing electrical thing I can think of is is the power supply getting past it's best? If it's having trouble running everything then it may take a while (or just not get there). Give it a try with the case open and a different PSU hooked up?

Oh unless the VGA is a bit off? Graphics cards post first I believe (not sure about onboard?) so if there's a problem with that it could be holding it up.

At what stage is it slow? Right at the start with no fans spinning or everything looking powered up and hanging at some point? Might help in tracking down the problem...

jimbouk - It used to be that once I pressed the Power Switch ON, it would take a while (a few seconds and then progressively a few minutes) before actually getting electrical current through - lights on, fans on and the operating system starting. Once it got started, I had not problems at all. Now, no power at all seems to get through. It's as if some capacitor in/next to the power unit was fried. Before I started taking that apart, I thought I would ask if anyone had had a similar problem. The machine runs just fine if the electrical current makes it through....

my bro has exactly the same problem, there's power getting to the m/b (very faint LED) but he now presses the 'on' button and goes off to make a cup of tea or something while he waits 30mins+ for it to fire into life...once it starts it's fine...

I suggested trying a new PSU due to the faint LED on the m/b but am not magnificently hopeful.

I have the same problem with a Shuttle SN41G2: when plugged to power, it takes 10 to 1 minute to fire up.

ok

But when it is unplugged form electricity power for a while (few hours), it takes ages to start (up to 20 minutes), and it seems to take longer an longer...

Can anyone confirme a motherboard battery replacement ?

thanks,

I've got one of these too and have/had the same problem till i found a work around. Putting the power on then pressing the reset button caused it to instantly kick in rather than needing to wait.

Try that?

These days you can get the right motherboard battery (normally a cr2032) from Asda/Tesco. I bought a box from batteryforce.co.uk as I tend to use a lot of them.

Google for the problem, I am sure I have seem people report this and I *think* the fix was a new PSU (or remove some power hungry card from the system).

I'm so glad I am not alone with this problem. My SN41G2 also started to boot very slowly. At first it was a few seconds, then it was minutes, and now it is hours ( if at all ) before showing signs of life.

The machine shows no signs of life, and then boots normally and works fine. The other morning it came to life at 4:30 to the annoyance of my wife.

If you remove the power and plug it back in, the fan spins momentarily, then goes back to sleep. I have tried resetting the CMOS by jumpering.

I will now try changing th CMOS battery, and will let you know how I get on.

Hello,

I bought a new PSU, the PC40 SilentX.
It solves the issue. My Shuttle box starts up instantly !

I knew replacing the CMOS was too good to be true. Needless to say it didn't work.

Will have to try the new PSU.

I got my bro to replace the PSU and HARRAH!

It is booting as normal again

slow boot indicates a failing psu , i have original 220w sn41/45 psu for sale at 25 delivered within uk

I had exactly the same problem with my SK41G, with the original 220W PSU. I confirmed my suspicions by temporarily hooking up a standard ATX PSU & the machine booted just fine. I took the cover off the faulty PSU & found 2 capacitors that had overheated & leaked - which easily explains why there was a long pause before they charged up & activated the PSU. It was too tricky to replace the caps, as they were covered in insulating glue, so I just bought a new PSU which has run fine since.

I had that same problem on a Shuttle SN45. I started this thread about it

Earlyer this year NightshadowUK had a similar problem with a normal ATX system, and started this thread about it.

I strongly suspect the PSU is at fault, and my first try would be to replace the PSU, or to try hooking up a spare ATX PSU to the system to see if it cures the problem.

[Fergie]

Yep, got this one covered now. PC50 300 watt fitted, and all is well in the shuttle box

So it looks like a new PSU is doing the trick for everyone on this thread who's had the boot problem. The existing PSU in my Shuttle SN41G2 is a 200W unit, 15 cm long. The replacement SilentX PC40 or PC50 is 19 cm long. Space looks very tight even if specs say it should fit. Has anyone fitted a PC40/50 in an SN41G2 unit?
