Optiplex 740 capacitor leaking

[shafe88]

Was cleaning my Dell Optiplex 740 and noticed one of the capacitor's was leaking. I have no problems what so ever. Right next to the capacitor it says c862

Hi

Be prepared for failure to bootup and strange messages from BIOS and amber instead of green power led.
You might get by if only one capacitor out of several similar ones fail but usually after a time more will fail.


There are a small number of specialist companies who can fit new high quality capacitors

which is probably better than buying a replacement motherboard which will fail in a few more years

How old is this PC ? some Dell PC's have a 3 year warrantee most 1 year
the bad capacitor problem was supposed to be over by 2006

Is their any way to tell how long it has been leaking.

Here is a source for a new Optiplex 740 motherboard. I have used these guys many times before. Always great to work with.

I don't think it's worth buying a replacement when I only paid $15 for the computer.

Agreed, there are some used mobos on the same site as well (19.95 I think). You can run until she drops. Just be sure to keep a backup of anything important stored on the system.

Good luck!

Is it safe to use with just the one bad capacitor bad, as it's not causing any problems.

Sure, it will be okay until the cap fails. One day, the system will likely just not boot properly or will start to shutdown randomly.

I think I don't haft to worry about the cap failing. When I was wiping some of the residue off the mother board the capacitor fail right off. Even with the capacitor gone every thing works perfect and still reliable as before.

Just keep an eye on things, keeping good backups. Swapping a mobo is always easy in one of those if it comes down to it.

I don't think it would be worth replacing the motherboard, when I can go back to the same place and get another computer for $15-20.

 

[COLGeek]

That is certainly an option.

I don't need to worry too much about backups as it's only used for games that only work on XP and their on cd.

Since the leads from the old capacitor are still attached to the motherboard, could I just get a capacitor thats the same and just solider it to the leads of the old capacitor, If I can solider a new one to the leads of the old one I think I could solider it without taking out the motherboard.

You could do that if you have the proper tools and parts, along with the patience and experience to do so. However, if one cap went bad, others will as well (most likely). You should consider the amount of time (and its value) in taking this on when you have other (less tedious) options.

But let there be no doubt, you can certainly replace a bad cap as suggested.

I think the best solution is to use it with the missing cap till it fully fails, since it's not worth fixing.
