    Re: Leave on, Turn off

    There are A lot of different brands, formfactors, and sizes, I have a lot of them around the house.
    My beef is with those that throw them away when they need only a battery.
    My second beef is the batteries going dead,,I mean dead dead.
    My third beef,, well never mind.
    Here and in most of the coastal waterways all around the world are these flashing light marine marker buoy's. Get up close but don't touch it and you'l see a solar power pack or UPS on it. Well here's the bad part, when they service them, new batteries,
    take a guess where the old dead batteries are going? Right, to the bottom.
    Over the years the battery carcasses have just been piling up under them where divers say they are used by fish and crabs as habitat. They catch those fish and crabs and guess who eats them at the crabshack.
    Oh boy, I went right from beef to seafood, anyone for chicken?

      anyway, back on topic, I leave my dell desktop on 24x7 except when it is not going to be used for about 5 days or more. My laptop (when it was working) I left on only as I was using it. Most pc's I recommend be on 24x7 especially with win98 (slow startup).

        Do you think the caps are most sressed when powered up cold then hot then cold etc.
        or just hot and a little cooler,(cloudy day), a little hotter(real scorcher), then hot, then hotter(oops a new wad of dust just came thru fan).
        It seems that the leave on turn off question is really still a hard one for me.
        I leave one laptop on, because it's outside and humid, wife leaves hers on 24/7 which is her perogative, entertainment system is rarely turned on,to lazy, and all others are maybe maybe not.

            what is it with those units. i have 2 420va which are the oldest UPS in the office. they do make the batteries real hot though but you definately get your moneys worth out of those UPS.

              Has anyone ever read the Equipment protection policy from American Power Conv.
              It states that the back ups pro, for example has a lifetime $150000. reimbursement and Ontrack data recovery.
              They are technically exposed by this because the language is very broad.
              Starts out, " If your electronic equipment is damaged by power line transients on an AC line while directly and properly connected to a standard APC product..."
              I new there was a reason for loving these, OMG I can retire now.

                HannStar Hanns-G HC194d LCD monitor repair
                by momaka
                Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                Heathkit IO-4205 Power Supply Caps
                by eryjus
                Hello,

                First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                ...

                Identifying caps on an old Zoom 9000
                by Paxman_Swede
                Hello!

                I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                I have studied the board and...

                Lenovo Y700-17ISK turn on and off
                by pajdek
                Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok. So i thought maybe lcd stripe is faulty, i removed the bottom cover, disconnected main battery, reset the cmos by disconnecting battery for 1 min, then slighty move the lcd stripe. Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on. Removed power supply, waited...

                Help with switching power supply caps
                by captain150
                I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
                I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...
