Capacitor replacement Dell Optiplex sx270


I am to repair a Dell Optiplex SX270.

Somebody already took off two faulty capacitors.

Now I got two new ones, but as I dont know how the old ones were placed, so I dont know where to place the two new ones. They have different values. One is named C203 on the motherboard. The other one I cant find a name for.

The old values where 16v 1800uf and 6,3v 2200uf

To all of us that are having the same problem-get hold of me after DEC. 17 Th, as I am going in for major surgery now, and we shall try an go thru the motherboard,together. Also not trying to be rude,but get hold of a few very small alligator clips, 4 - 6 of them, which you will keep in the freezer for "Heat Shunts" while soldering,the units on,if you do not already do so. I also at times, put my capacitors,and any sealed units,I am to solder on, put them in a zip-lock with 2-4 little sachets,or little barrels used in medical pills-vitamins ,etc, and put them in with the components,to keep the moisture down. DO NOT LEAVE THEM IN THE FREEZER FOR DAYS,AS SOME COMPONENTS DO HAVE FLUIDS OF A SORT, CONTAINED IN THEM ! Most Important. these can freeze and burst , or split the units, 15 - 20 minutes ,MAX, say no more. Talk Soon- Jon .E mail I will give you when we talk next,gang
