    Datron/Siemaks M600VD3 UPS bad charger 400V cap

    A few weeks ago, I bought a Datron/Siemaks M600VD3 online double conversion UPS from a local junkyard. The only problem was that the 400V 68uF 105C Marcon AUF series unit in the power supply have bulged after 13 years of use, causing the charger to not charge the batteries (which still retained a charge after recharging).
    Replacing this capacitor made the unit work again.
    13 years is quite a reasonable life for such a capacitor... and the unit had extensive protection logic inside it.
    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.

          ASUS X54H laptop thinks it's always charging even with charger unplugged
          by flat-earther
          The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

          Windows also shows ''Plugged in'' when charger is not connected.

          This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
          Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
          If I let battery run out and say it has 3% Windows will...

          Lenovo T460 Only Charges on One Charger
          by motormayhem
          Laptop Question
          Hello,
          I'm working on a Lenovo T460 that has been having trouble charging as of late. Its worked well since I've owned it for a few years. When I went to use it the other day it was dead and wouldn't turn on (was sitting on an Anker 65W GaN charger). After some fiddling with the charger I got it to turn on and start charging, but seemed like the charger was not working as it should (took a few plug and unplug cycles to get it to start charging).

          A day later it was dead again and wouldn't boot/charge no matter what I did. No lights or anything when...

          ISL88739AHRZ ISL88739 Laptop Battery Charger Datasheet
          by Document Archive
          The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
          configurable for operating as either a Hybrid Power Boost (HPB)
          charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
          4-cell batteries. Both configurations allow the battery to work with
          the adapter together to supply the system load when it exceeds
          the adapter capability, referred to as system Turbo mode. HPB
          charger configuration reverse-boosts battery energy to the system
          bus to help the adapter provide the system power in Turbo mode.
          NVDC charger configuration...

          Dell Inspiron 7567 LA-D993P odd charger issue
          by Johndill
          Hi, I have a Dell Inspiron 7567 LA-D993P that I've just got running.
          There was corrosion around PU1503 which shorted PC1518 & blew PL1504. (Reference pictures attached)
          I've replaced PC1518 & PL1504 & the laptop is now running however I now have another issue.

          Here are the tested scenarios:

          1. With the laptop running on battery, I plug in the 150W charger & the charger shuts off (no LED, protection mode) but the laptop remains running on battery.

          2. With the laptop off, plug in charger (LED says on) & the front charging...

          Highly Integrated Narrow VDC Battery Charger for Notebook Computers

          The ISL6257HRZ ISL6257HRZ-T is a highly integrated battery charger controller
          for Li-Ion/Li-Ion polymer batteries. ISL6257 is designed for
          Narrow VDC applications where the system power source is
          either the battery pack or the regulated output of the charger.
          This makes the max voltage to the system equal to the max
          battery voltage instead of the max adapter voltage. Operating
          at lower system voltage can improve...
