Re: Dell 2007FPB teardown

If it's so cheap, sure. You can actually use the whole replacement board, if it's sold as working.

Re: Samxon capacitor quality discussion (spin-off from OCZ Bug Zapper thread)

Who knows, I've already repaired strange IBM systems with Socket 478, reportedly it runs some huge printer, if you had gazilion printing material for close to nothing, you'd also keep such beast...

Re: Dell 2007FPB teardown

If that's correct, first transformer's busted, that's what's making the driver shut down.

Re: Samxon capacitor quality discussion (spin-off from OCZ Bug Zapper thread)

Most of those caps died after 11 years of use no matter was it Sanyo, Rubycon, Nichicon or NCC (obviously) caps, especially in these terrible Dell systems. That's pretty much confirmation Samxons...

Re: Dell 2007FPB teardown

Check the secondary sides of those three inverter transformers, if all six have the same (within 1-2 %) resistance.

Re: Dell 2007FPB teardown

Phone's usually not enough, there are two polarisation filters 90 against each other so almost no light comes through, you need some strong light to se. However if the indicator LEDs are on, likely...

Re: FSP400-60GLN worth fixing?

Shitano is known crap which tends to bloat in storage. I kinda wonder what do you mean about availability when I have pretty much everything regarding ATX PSUs for like 8 years straight now and you...

Re: Samxon capacitor quality discussion (spin-off from OCZ Bug Zapper thread)

Just for some upgrade after 5 more years, I had two RS 330/25 caps (or something like that) dead in an old router some time back, but that thing was running quite warm for many years 24/7 after...

Does it shut down completely, or just the backlight?

Re: Tecnoware FAL501FS12 does not turn on

If that's the case, only explanation is one of them went high(er) ESR, hence, by ohms law, the different voltage. But, that situation likely happened over time and I think is not the most accute...

Re: APC UPS units - troubleshooting

Guess it was just initial drop due to high initial current draw. Plus, pretty much no accumulator has flat didscharge curve - it usually drops quickly from full charge to about 11.5 volts, than...

Re: APC UPS units - troubleshooting

Those were likely the close to 2 decades old platforms, SU1000I.

The boards are pretty much the same for 1000- and 1500VA units, but the fan circuitry incl. the connector are missing for 1000VA...

Re: APC UPS units - troubleshooting

Nine years, I'd do it this time replacing the accumulators.

Voltage won't tell you anything when it's running, even if acting only as capacitors, they'd read correct voltage as the charger...

Re: Power supply build quality pictorial. part 2

Re: Power supply build quality pictorial. part 2

Smell gutless wonder all the way to me. Was it rated 400 W, that would likely be OK, lets say slightly underrated Fortron THN-P (BlueStorm) of that era. Labeling it almost 600 W and being a 300ish...

Suncon still produces WG so 3300/6.3 are still easily available, plus I got some stock of Rubies MFZ 2700/6.3.

Re: Just when you thought polymers gave a PC eternal life! - The GX745 SFF Calamity!

And much faster core speed, however being 45nm lito and totally different core, it needs at least G31 to run properly. I think there were some special cases of 965 chipsets with support for that, but...

Re: Just when you thought polymers gave a PC eternal life! - The GX745 SFF Calamity!

Likely depends on stepping, later steppings need different microcode, as guys already said.

Could be that it's now so cheap it does not matter, but usually it is that the most powerfull CPU of any...

Re: Just when you thought polymers gave a PC eternal life! - The GX745 SFF Calamity!

Oh yeah, I thought it had older chipset but not, so it should take Q6600. Look for the latest stepping, that one has 95W TDP.
