      Thanks, that's indeed B not 8, my mistake, but next to it definetely is 10. Will there work any LDO to specified controller operating voltage, say 4.35-4.9V?

              Help Needed: Reverse Polarity Issue on HP EliteBook 840 G4 – Where Do I Begin?
              by Dev Goose
              Hi everyone, I recently acquired an HP EliteBook 840 G4 (6050A2854301-MB-A01) that I'm hoping to bring back to life. I'm fairly new to laptop repairs but eager to learn and willing to put in the effort to understand and fix this. Any advice or guidance would mean a lot!


              What Happened
              The issue started when the laptop was accidentally plugged in with reverse polarity. Before this incident, the laptop would show a power/charging light whenever it was plugged in. However, now it's completely unresponsive—no lights, no power, nothing. I've been doing some research and understand

              What will happen when charger is reversed polarity?
              by sikocan
              Hi all, I've got a laptop coming in soon and apparently they used an external power bank to deliver 19v to DC Jack so they can charge out and about. Which is fine, but they've accidentally got the polarity wrong and injected 19v through DC Jack. And it doesn't charge anymore or work of DC Jack, but works of remaining battery. My assumption is it'll be a simple case of replacing a diode which I believe it's job to prevent this happening and it may have burnt. Would I be right on this? Thanks

              Logitech R20 speakers - Replacing one of the speakers.
              by Widget
              Hi guys,

              I have a set of Logitech R20 speakers, one of the speakers wasn't working, so I took it apart & there was no continuity or Resistance when probing the Tinsel Wires. Plus looks like the speaker was exposed to liquid as there's rust on the metal speaker frame.

              Just in case, I removed the other speaker and installed it in place of the damaged speaker to make sure the PCB of the damaged speaker was ok & it seemed to work fine, so it looks like it's just the speaker for now.

              Printed on the back of the Logitech speaker is;

              Weird clipping on Logitech Z-10 speakers
              by dreamlayers
              I bought used Logitech Z-10 computer speakers. They can act as a USB audio device or accept line input, and they have a headphone output jack. Some music didn't sound right, so I played a frequency sweep and heard other frequencies and beat frequencies between them and the sweep. I uploaded a spectrogram of a frequency sweep. From the very start, some but not all odd harmonics are visible, indicating symmetric distortion. Then at higher frequencies there are descending images of those harmonics, indicating non-linearity and constant higher frequency noise mixing with the harmonics. The image of...
