    Oracle Micros DT Research Battery Charger ACC-001-33M

    Hi,
    I have this charger, it's meant to recharge 4 batteries at a time. It has been probably connected to a 19vcharger instead of the correct 12v charger and it does not work anymore. I disassembled it and found a broken (shorted) diode (D22).
    So I replaced the broken diode with a similar diode pulled from the same board but it broke (very hot) even with correct 12v charger.
    Any hint? Maybe it's a standard circuit. Sorry I'm a noob.
    Thanks in advance

      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...

      DELL Alienware 17 R3 (LA-C912P) only work with 120w charger in mode low CPU clock
      by exerion5000
      Hello, I received this laptop with the following condition: When I turn it on, it shows the ALIENWARE light and the Alien button lights up, then it does not show an image and it restarts constantly, as the customer had already informed me that the battery was dead, I connected an original charger that I had it for testing, the machine turned on normally and I was able to enter Windows without problems, after a while of testing I noticed that it is very slow (like a Cyrix 425...), and after performing a CPU test the frequency is
      below normal, as if it were operating in an extreme energy...

      Adaptable charger voltage for Clevo D901C laptop
      by HERETIK10
      Hello everyone,
      Thanks in advance to anyone who takes the time to help me. Sorry for the quality of my English, I had to use a translator at times...

      I bought a functional Clevo D901C (Sager NP 92261) with its battery but without its power supply.
      So, I invested in a new LiteOn charger, advertised by an online seller as the right charger for my machine... BUT, according to the pinout (4pin + shell) of the charger, 1 and 2 are 20V / and 3 and 4 are grounded. When I measure pin 4 with the ground of the PC, I have 300kOhms, which seems to be confirmed by the electrical...
