there is no reaction, it hangs at 20 V/0A. There was a little corrosion in the u7650 area. Replacing the u7000 did not help. Tell me, what else could it be? PPBUS_G3H=12.9V

I bought a T12-958 recently with an M8 handle and until now it has worked very well. The tip wasn't earthed but that was easily resolved.
Now, whenever it is switched on, it heats up to about 70*C then shows an [INVER] error on the screen and stops. In order to fix it I have to either unplug and re-plug the handle, or unplug and re-insert the tip from the handle. While doing that it changes to [ERROR], then it finishes heating up and works perfectly. Until it's turned off, after which it will show [INVER] again next time it is turned on.
Any idea what the problem is?Yesterday, 01:36 PM -
Hello guys
Because the unit is old (but only occasionally used) the loudness button causes some noise due to bad contact,
sprays did not work, so i decided to solder the pins that it connects on the pcb at the on (loudness on) position
i did that and it worked fine, i know from the bottom of my heart that the switch connects 2 pins and also d/c other 2 pins
on every position it have (6 pin switch), so i was curious what would happen if i clicked the switch off while the pins are soldered at on (so basiclly on and off at the same time), when i did so the sound is gone, nothing...05-05-2024, 06:20 AM -
Hello guys
My laptop have a FAN issue, i tried with a new FAN but the issue persist.
The motherboar is LA-G714P
I measured the JFAN1 connector
pin 1: 5v
pin 2: 0v FAN1_PWM
pin 3: 3v FAN1_TACH (this pin should not be 0v if the fan is off??)
pin 4: GND

Hello, this might be embarassing since I consider it a dumb question but keeps me kinda stuck sometimes in my journey.

Hi everyone, I have the same problem with two Dell notebooks. One has the EDC41 LA-G891P motherboard and the other has the EDC50 LA-901P motherboard. Both do not turn on and the processor also heats up a little.
In the coils there are 3.3v - 5.1v - 13v - 19v - 1.8 - 1.05V and 1.0V prime core
On both notebooks, if I press the power button the LED turns red and if I release the button the LED turns off.
What could I still check before saying the processor is dead?
Thank youToday, 01:22 PM -

This has happened on three keyboards, so now I am assuming it is something in the machine but I can't track it down. Every time you plug in a logitech wireless keyboard it will immediately switch the "c" and the "v" permanent on these boards. There is no malicious software I can find, the board cannot be reset or put back. The very last one I tried was a MK 235 with the same end result. If you plug in a Microsoft wired comfort curve board, no problem at all. I have tried cleaning the system, deleting all boards from the device manager, updating the Logi software,checking MS...Today, 12:02 PM

Shown in picture, trying to replace a MOSFET and looks like I knocked this off, in guessing it's the same as one next to it. Has 1.8 Mohms. Any way to bypass it? It's on the hot side
The component circled is the one there, the arrow is I think another of same component?Yesterday, 11:47 AM
