Do bad caps in GX270/280 cause the amber power button?

[Arpajon]

I'm currently going through all the GX270 and GX280 units I have left to see which ones have bad caps. Several of each model have visibly good caps, but the power button stays amber when pressed. If my memory serves me correctly, the likeliest diagnosis for the amber power button is a bad power supply, but I tested a couple of them just for grins and they tested fine.

I realize that caps can be bad without leaking or doming but can't remember if bad caps could be the cause of the solid amber power button. Anyone here remember anything that could help?

Thanks in advance for any assistance.

Check the caps on the motherboard.

Check the caps on the motherboard.

They are visibly OK. I'm unfamiliar with how to do any additional checking.

I just went through a bunch more of these. I thought I'd repost to see if anyone remembered whether or not the solid amber power button on a GX280 could be caused by bad caps, even though they're visibly OK. I'm in the process of recapping a bunch of 270s that will boot to BIOS even though there are caps on the mobo that are leaky or visibly domed. I'm OK with recapping the 280s as well, but I'm hoping to find out first if that's a likely fix before I got to the trouble.

Thanks in advance for any help.

are you sure the psu is good?

It can and it is.. but swap the psu with one of the workers before going to the trouble of capping the board to see if that makes any difference. Other causes can be bad/corrupt bios

I didn't check each power supply today. In the past, I've both tested and swapped out power supplies and they were fine. I can try testing/swapping a few next week. As I understand it, the solid amber power button light indicates a motherboard issue and flashing amber indicates power supply. I was just hoping to discover whether recapping might be a solution or if that is likely to be indicative of other motherboard issues.

Thanks. Your response came while I was responding to the previous post. As I said there, I'll swap out and test a few power supplies next week.

Re: BIOS, I guess that means the board is hosed since I can't get anywhere during the attempted boot, so I'm unable to flash the BIOS.

You can always try a few "usual suspects" cap replacements and see if you can get at least an attempt at a boot.. That's why I pull old caps and the ones which test borderline rather than fail go in a bag for just this use. Another trick if you have more than one of these boards and the bios chip is socketed.. swap it for a known good one

I had one with a bad PSU (bad capacitors) which caused an orange light. I think the light was also flashing.
