    Hard rubber bungs = bad units?

    I have a few LCC (Thomson) electrolytics which have hard rubber bungs.
    Does this indicate that they are possibly bad?

    Also, I know that few electrolytic capacitors use epoxy bungs (which are more expensive).
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

      it could indicate they are old.

      as for epoxy, it's not the bung afaik, it covers the bung.
      i'v had loads of those on old (early 80's) american pcb's.
      they seem to have held up better than average.

      maybe i'll see who makes them next time i see some.

          **Need Help Unlocking BIOS and Hard Drive on Dell Precision 5820 Tower**
          by federalhouse
          Hi everyone,

          I'm in need of assistance with a Dell Precision 5820 Tower. The BIOS is locked with "Dell Security Manager," preventing access to the HDD-1 hard drive.


          **Background:**

          I recently purchased this Dell Precision 5820 Tower from a recycler who salvages equipment from abandoned office spaces. The computer was left behind by its previous owner and was password locked. Given that it can run Windows 11, I saw this as an opportunity to upgrade my setup.


          **What I've Tried So Far:**

          Sony OLED XR-77A80J - 5 Flashes But Turn On After Hard Reset
          by odie34
          I am a hobbyist (not a professional) so please be gentle...

          I recently received an XR-77A80J that wouldn't turn on. (Repeating 5 flashes when plugged in.)

          I did a hard reset by holding the power button for about 30 seconds until the set powered down. I then tried to turn it on and it powered up, bringing me to the setup screen. There's not a lot of detail on the setup screen but the picture didn't have any distortions, so at least a cursory examination suggests no physical damage to the screen. The set appeared to be working normally, but it shut down after about 15 seconds,...

          PC case - Hard drive rails
          by tmcw
          A friend gave me his old PC case (with MB, and PSU), but no hard drive rails, he said he only used the 2.5" SSD spot inside, and used an external hard drive for data. He said that he'd have a look for the supplied rails, but I doubt he'll find them.

          So I was wondering if case manufacturers used any type of standard 3.5" hard drive rail?

          I'm used to the various Dell hard drive caddies or rails (and HP and Lenovo to a lesser extent), or el cheapo cases where you screw through the frame to fix the drive.

          Now, the case is a CiT Gaming Case, and...
