Re: Lots of capacitors with leaking electrolyte

Hi STJ... I did know that there are similar electrolytics in the power supply but I hadn't considered that they might be causing issues. I do note, however, that this is the second power supply in this computer... The original supply just quit one day (maybe due to cap failures??) about two years ago and I took another supply out of a similar computer that was being scrapped and it's worked fine since... Also, when I bought this new motherboard, I also bought a power supply at the same time but haven't put it in... Again, once I got...

Re: Lots of capacitors with leaking electrolyte

Hi Cap_Out... I looked up your part number on the Impact website and it sure looks similar to my board... And since you found that number and they had a board with that number that says it's for a Precision Workstation 650, I'd say you have the correct board...

Regarding taking out your old motherboard (I had never done such before I did this one) it turned out to be quite easy, though scary the first time... Assuming your's is like mine I will quickly summarize below but also point you to this very important dell page...

Re: Lots of capacitors with leaking electrolyte

Hi... I have not heard of that number, XM760... I did buy a new (refurbished) motherboard, installed it and it fixed my problems entirely... I also, while I was waiting for that new motherboard, separately bought new capacitors, replaced them on my original motherboard and that motherboard sits here in my office... The refurb'd one came in just before I finished recapping my original so the refurb'd one went in first... Since it works, I've been unwilling to explant it just to see if my recapping was successful...

But...

Re: Lots of capacitors with leaking electrolyte

OK, answered my own question... Removed the nine screws but it still had all these ground clips, etc., that seemed to be holding the pc board to the back plate... But by sliding the PC board slightly away from the back connector, it all broke free and I was able to separate the pc board from the aluminum back plate... Now I have to decide if I want to try to replace all the caps myself... thanks much... bob...

Re: Lots of capacitors with leaking electrolyte

Hi... I think there might have been confusion from an earlier question of mine where I asked how to remove the plate from the motherboard... I meant the plate that on mine, an f1262 motherboard out of a Dell Precision 650 Workstation, fits over the back of the PC motherboard itself... Granted the entire assembly consisting of the motherboard and this backing plate comes out of the computer by the removal first of a single screw and then by lifting a couple tabs on this metal backing plate and then you slide the entire assembly out...

Got it... Appreciate the help... thanks a lot... bob...

Re: Lots of capacitors with leaking electrolyte

Hi... I work at a large, secure National Lab where sending out stuff like the motherboard out of my computer is suuuuuuuuuuch a headache... Now getting stuff in like a replacement motherboard isn't so hard... So that's why I haven't (yet) moved in the direction you suggest..

And granted, motherboard replacement is certainly NOT a slamdunk... Does the replacement motherboard work?? In my machine with my configuration??? Is that even my problem??? At least half my capacitors are leaking brown stuff out the top although...

Re: Lots of capacitors with leaking electrolyte

Thanks Shadow... Appreciate the help... I am going to go ahead and give a shot at installing a refurbished Motherboard replacement... It's only $150 and it appears (might be famous last words) that changing out the motherboard isn't too hard a task... My biggest fear is removing the heat sink and processor from the old board and replacing that on the new... Beyond that, however, I just decided to risk $150 of the company's money and see if we can get some more time out of this existing PC... Money is tight where I work right now......

Hi... I have a Dell Precision 650 workstation that was purchased in May of 2003... Recently it became very unstable on startup... I will start it up. The moment Windows XP starts to load, most of the time I hear what I think is likely the click of a relay and in that very moment, the startup process ceases and the ABCD code on the four LED's on the front of the Dell changes from 4 Green LED's to instead Green (A), Yellow (B), Yellow (C) and Off (D). The dell manual describes that code as "a possible VRM 0 failure has occurred"... I read elsewhere on the web that this can also be just...
