    Clevo P775TM1(XMG Ultra 17) Fans 100% and then turns off

    Hello, I have a problem with my P775TM1. When I turn it on the display stays black, after a while the fans spins at 100% and the led is blinking orange. After a few seconds the laptop turns off. CPU, RAM and GPU are working fine in another P775TM. I have also tried a cmos reset and flashed the Bios to the newest XMG Ultra Version.
    Can anyone help me to find a solution?

          I flashed also another EC Version. Now on battery it starts for 2-3 Seconds and turns off. On A/C Adapter it turns on without pushing the power button and the fans are spinning with 100%.

              Flash the bios and EC from XMG.Don`t flash the ones from the repo.

                      You can but you will lose the customised features if there are any for your model.

                          I flashed Bios and EC and tried also my dump version again. But the old symptoms didn’t come back.

                              What do I need to Programm via J_Flash1/2 connector? I want to flash the main EC.

                                  So, the reflashing didn‘t work. Can you tell me where to measure the voltages?

                                      The laptop is CLEVO N970TF with i5-9400, RTX2070, i haven't disassembled it yet to know what is the board number, i will update that later, but the issue is laptop turns on normally and works for about 2 minutes,then both fans turn on to the max and in 30 seconds laptop shuts down! Nothing is warm or even close to overheating...

                                      i manage to get linux up and running and monitor the temperatures from all sensors, and the peak one is 51 celsius from a cpu cores...

                                      So something is acting up and thinks the laptop is overheating? How to foul the board into thinking everything...

                                      I removed battery, hdd, rams, bios battery, then pressed power button for 30 sec to drain out all energy, still same thing, i did check both mosfets on power module of the board, pq301 and pq302, i get 20,5V on all pins except one pin that have 8.7V

                                      Connected external keyboard, tried on all 3 usb ports, no leds on the keyboard, neither numlock, checked voltage on usb pins, i only have 5.1V on 1 pin, rest 0V

                                      MacBook Pro Mid 2012 turns on, fans spin for five seconds and turns off, repeats
                                      by Gigabit2
                                      I have a MacBook Pro Mid 2012 with 820-3330-B board.

                                      The laptop shows a green light on the charger, turns on and the fans spin for about five seconds. Then it turns off and this repeats over and over.

                                      Before it turns off, the SuperDrive (DVD/CD drive) makes a noise like it does when it first turns on from cold (on a working machine).

                                      I am stumped, can anyone help?

                                      RTX3090 working fine but fans not spinning
                                      by emil_t
                                      Hello guys. I have a problem with a PNY XLR8 GAMING RTX3090 graphics card. The problem is that it displays and works fine, but the fans don't spin at all. The problem occurred when someone else removed the fans in order to clean it and broke one of the fan connectors. He replaced it himself and after that, it wasn't working anymore. I guess he damaged something else in the process. What i have done so far: I found 2 capacitors next to the connector that were in a bad shape, he must have touched them with his tools - they weren't shorted, but i replaced them with similar ones from a similar card....
