          Hello,

          I'm looking for this IC to replace one on another board that was damaged. However, I can't find it. This is for an HMI board.

          Looking through the code tables, I can't find it. I thought it was from RICHTEK (RT9011), but in email exchanges, they told me it is not one of their products.

          Do you know the MPS code for it? I tried to find it but couldn't.

                  I think you nailed it. Is there a backlight LED feed nearby? This is a LED driver IC.

                      Yep!

                      he LCD display connects to this board. There are also some push-buttons with LEDs.

                      Thank you so much!!!

                          Cannot find PS5 IC (marking F2=8D) part number
                          by tech_guru
                          Hello everyone.
                          Is there any chance somebody can find the part number of this chip or equivalent, in the attached photo?
                          It is from PS5 EDM-020 board, in the front usb section, near F3502.
                          It must be a Richtek ic, vqfn32 package style.
                          Thank you in advance....

                          by redbaron1007
                          I got a High Power HP1-J600GD-F12S on the bench today that was killed by roaches judging by the dead roaches and large brown spots in the housing next to said roaches.

                          I was able to identify all the blown smd resistors on the board aside from the one located at R69. I wasn't able to figure out what any of the marking on the resistor was supposed to be and with how little of the marking was left I wasn't able to really make any guesses about what it could be from the surrounding components. It is connected to pin 1 of Q11 (4N65SFA1K) which looks like it is the gate .In the sample...

                          Hi, I just come to this laptop with symptoms from owner - it stop charging. Thought it would be easy USB-C replacement (matebooks known issue) I took it. But port is good. After charging battery from power supply laptop is still dead. No power to EC chip. I'm out of ideas what to check next.

                          Next to 3.3V LDO which is only active rail after main rail is a circuit which sends voltage to EC chip. I don't understand at all function of this circuit. It consist of 2 PNP transistors few resistors and P-channel mosfet. Below is a circuit diagram of that part with explanation. Does anybody...

                          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                          ...
