I've been having the "bulging capacitor" problem a lot as of late on several systems here (25% of my GX270 systems so far).
Also, after doing some research...it seems that this is quite a common problem. However, the GX270's specifically have an issue where the capacitors were overfilled (in addition to the 'other' common problems with bad capacitors). Some have said that it is their "early ordered" GX270 systems with this problem.. There may be some truth to this, but I don't have enough systems on site to fairly diagnose this as being the case (checking with other offices now, though, I'm sure some of them will know).
The technician who just replaced a few motherboards here due to the [apparently well known] issue of bulging capacitors on the GX270 told me that a lot of companies have demanded their entire fleet of 270's be replaced, and they've done it. (and not only has Dell done it, Dell has sent contractors out to the site to do the work of the swap outs).
He told me he has "heard through the grapevine" that Dell will be issuing a recall on the GX270 systems that are affect in the next month or two. Is there any truth to this? Is there an "easy" way to figure out which systems specifically are effected?
