At 12:00 I accidentally put up a clip of the fixed cable before I shrunk the heat shrink tubing. I of course shrunk the heat shrink tubing before installing it into the system, and you can peep that in the next clip.
Great video!! Soldering is hard to do. It's awesome to see you try on that board. It was in such bad shape to begin with!! Those are surprisingly good little computers. Id love to see more of these diagnose repair/replace videos. Good approach and video style.
Great video! I love your troubleshooting steps. I think it was smart to replace the motherboard with it being so cheap, it makes much more economical sense IMO
Your observation about the battery was interesting. I changed a ton of cmos batteries in this era of Dell computers but I never made the Mitsubishi connection. It seemed that after this era I never had to change one again. One of the Dells, I think the 790, they put the CMOS battery under the overhanging part of the heat sink on the back of the board, so you always had to remove the heatsink to change the battery, and of course, ideally you'd put new paste on it, which was an added expense.
I haven't had much experience with the 790, but that battery positioning does seem kind of annoying. And yeah, all of the Dells that I deal with from this era seem to have dead CMOS batteries, and the few that don't aren't using Mitsubishi batteries. Interesting how those specific cells die so quickly compared to others, I think!
Good call re PSU warnings. I had a old PC PSU in my shed that had been in a box of parts for easily 1 year, maybe more. I wanted to rob the fan from it so took it apart and thought "Better short the caps just in case". And i put a screwdriver across the 400v cap on the HV side and CRACK!. It still had a hell of a charge. Thank god i did that and didnt accidentally put my hand on the underside of the PSU.
A good cleaner for this, in my experience, is actually some contact cleaner from an autoparts store. It basically desolves the oxidised metal, making it easier to clean.
Just investigated my similar problem. Battery was at 0.0V, pretty sure it was new 6months ago. Put a new battery in. Removed motherboard, all looks OK. Re-attached most parts, Motheboard just clicks but nothing else. Battery down to 2.8V (from 3.3V) after 20mins. Refurbed M/B on order.
That power cable hack job was pretty pointless imo,i mean you could get a sata splitter for less than 1$. I have one of those splitters in my sff optiplex which powers 1 ssd and a hard drive and also the dvd drive and it's no issue at all. You can also try car circuitry corrosion cleaners,that's what i use on my boards and it attacks the corrosion really heavy without harming the board. I actually saved one board from corrosion using that cleaner and it still works to this day
The solid amber light? Not entirely, in my case I'm pretty sure it was due to the liquid damage, and I couldn't repair that, so I needed a new motherboard to fix that issue. If it's a flashing orange light though, there are a few things: RAM issues CPU issues Motherboard issues Give reseating your CPU/RAM a try, as well as using a known good stick of RAM in all four slots if you have one. It's possible the RAM just needs a reseat, you could have a dead DIMM, dead slot, or dead memory channel. It's also possible that some of the contacts on the CPU which work with the memory, or another part of the board aren't making contact anymore and need to be reseated. For CPU issues, really the only things you can do are reseating the CPU and trying another known good CPU if you have one on hand. And for motherboard issues, it's a chance something's gone bad on the board, BUT try a fresh CMOS battery. I've had several of these older OptiPlexes give a flashing orange light because of a dead CMOS battery, so check that for sure! I hope at least some of this could be helpful, cheers!
I have an hp laptop that I patched and it will restart ( up and running and restart ). but if you let it powerdown - It will not power up. I have replace the battery and that did not work ( it was a hail marry move ). but based on your comments - that it looks like the cmos battery could prevent - even power on. so I will try that. thank you
You don't necessarily see a bulge in those caps, but I noticed that some of the leakage was nearby one or two of them. Just unsolder them and check the capacitance and the equivalent series resistance (ESR). @@CHWTT

@@CHWTT no, just don't call it a fix. Other channels that do real repair would have cleaned the rust, restore missing paths, replace capacitors etc. to get the board working.
@@stzokev when i had my business i usually replaced the board for customers because its faster then i kept the old board if the customer didn't want it and when i had some time i fixed it and keep it for the next customer
I would very much rather do that if I were skilled enough at this time to be able to complete that repair successfully. As you saw, I very much tried, but I wasn't able to get it working. I'm working on building that skillset. And I think we'll have to agree to disagree on whether or not it should be called a fix, because I'm looking at the system as a whole, and it went from non-functional to functional, which means the system was repaired/fixed. If we look at the board and only the board, you're certainly right about that being a replacement, but I'm not looking at just the board.

I enjoyed your video. I have a SFF OptiPlex 7010 that I've built up to be a modest gaming PC, mostly because I like tinkering with it.

good a new motherboard was pretty cheap good video
Hi, just a quick question. Do you know how to fix dell optiplexes that have amber light?
The solid amber light? Not entirely, in my case I'm pretty sure it was due to the liquid damage, and I couldn't repair that, so I needed a new motherboard to fix that issue.
If it's a flashing orange light though, there are a few things:
RAM issues
CPU issues
Motherboard issues
Give reseating your CPU/RAM a try, as well as using a known good stick of RAM in all four slots if you have one. It's possible the RAM just needs a reseat, you could have a dead DIMM, dead slot, or dead memory channel. It's also possible that some of the contacts on the CPU which work with the memory, or another part of the board aren't making contact anymore and need to be reseated.
For CPU issues, really the only things you can do are reseating the CPU and trying another known good CPU if you have one on hand.
And for motherboard issues, it's a chance something's gone bad on the board, BUT try a fresh CMOS battery. I've had several of these older OptiPlexes give a flashing orange light because of a dead CMOS battery, so check that for sure!
I hope at least some of this could be helpful, cheers!

battery could prevent - even power on. so I will try that. thank you

I use vinager to take out the corrotion

Where can I get a 7020 SFF motherboard?
I've had great luck on eBay here in the states, but if you're located elsewhere, I'm not sure what the markets would look like there.
If I find something like this I'd probably use it as a low powered gaming PC, just replacing the motherboard and other parts
i love my 9020 usff but they are rare as in australia

I can only guess that some of those caps on the old motherboard were bad…
It's possible, but I didn't see any obviously damaged capacitors sadly. Would have been nice to see an easy fix like that.

Failing cmos batteries can sometimes just cause the most nonsensical issues.
Use vinegar on the corrosion before IPA. Another mistake, installing Windows.
