I live in an apartment building where each unit is independently heated via electrical in wall radiant heat, could it be the weather getting colder and everyone turning on their electrical causing noise? I don't notice problems with nay of my other appliances (including appliances that would seemingly be sensitive to this, be they lights (no flickering) or plasma tv. Could it be 'noise' of some sort on the line? i.e. Is it my UPS having problems or is it indicative of a problem with my power? I'd note that apcupsd doesn't show any power transfers, I just have these clicks. I'd think the clicking is indicative of voltage issues, but I have it on low sensitivity mode (and have expanded the lo/high voltages to their limits. I've drained it via a test or by unplugging) so its charging itself, there are is no clicking (or at least significantly less clicking) In that its constantly clicking when its fully charged.

Reverse Engineering TrendChip Firmware (ZTE-H108NS).So, I'm having a weird behavior with my APC Back-UPS RS 1000 (relatively old, batteries were just replaced).

Next Next post: TrendChip firmware (ZTE-H108NS): Derived works Recent Posts Update: The UPS works again after I changed C40. I don’t have the will power currently to try the fix but I thought that others may find this bit useful.

Change also capacitor C40 in addition to capacitor C56, C60 and C71.

It is not in English but it translates quite nice. It doesn’t charge and cannot handle any kind of load in battery.īy doing some more research on the Internet I found this. Anyway I fixed the ground but the UPS continues to behave erratically. This time the problem was that my custom mage power plug had disconnected ground. Per advice I used 3 capacitors 50V, 22mF. Note: The replacement capacitor specifications are 25V, 22mF for the first two and 16V, 22mF for the third. The fix this time was to follow the advice in comment and replace a third capacitor. Update: The UPS broke again with the same or similar (can’t remember exactly) behavior. I changed the faulty capacitors with normal capacitors and lo and behold! It worked!

Since I am not much of an expert in soldering and removing surface mount (SM) electrolytic capacitors I found (easily this time) another youtube video to figure how to get rid of them. The youtube video where you can find the original comment is If you turn on the red light of “overload” you have to change the two electrolytes marked in the photo this: The comment translated in google translate says: So I am posting it here for future reference. Instead the solution was in the comment section (yes I read youtube comments – can you imagine that?) in Spanish by Lujan Luis Giaccardi with the picture that shows the faulty capacitors red circled. If it was in the video or in the title then the solution will be findable by google. I am writing the post because the solution is not in a youtube video but in a comment. I doubt if it is faster this way but lots of people are actually posting very useful stuff there especially for obscure repairs such as this one. However in electronics repair hackery it actually makes some sense to present your work in a youtube video.

I prefer a text with properly defined steps than a 15′ video documenting a series of three clicks in order to access the desired submenu. If you are like me then you are totally against the wave of video tutorials that are flooding our everyday life. This time however the solution didn’t come from google but from youtube. I was handed this UPS and naturally I employed all my google foo in order to save a seemingly fine UPS. A google search did not reveal any solution other than the board is faulty and there is nothing you can do about it. The problem is that the UPS overload red light is constantly turned on even with no load at all. That is a quick and easy fix of a very common problem of APC Back-UPS series.
