Howdy everyone! I hope all is well where ever you are!
I'm attempting to integrate a couple of LED pods into an automotive reverse lamp circuit. The problem being, while the vehicle is running there is a 8.5v current present on the reverse lamp power wire. Needless to say is that all LED pods and lights dimly illuminate while the 8.5v is present, so the LEDs are always powered on while the vehicle is running. When the vehicle is shifted into reverse, the voltage changes to 12 volts.
I am uncertain how to convert this line into a switched 12v output line for the LED pods.... -
Oberservation:
X1 Carbon 4th Gen runs very slowly. Task manager shows the CPU running at 400 MHz.
In rare cases (1 out of 20) it runs at normal speed.
It does so when running on battery or only with the charger.
When both are connected - charger and battery (50% charged) - the system switches between charger and battery once per second.
The laptop does exactly the same thing when running Windows or Linux, so OS level problems can be ruled out.
Flashing CleanME and a different BIOS made no difference.

Hi all, need some help. I have a Samsung NP370E4K-KD2BR, which as a 5th Gen Intel CPU that works fine when running with the charger plugged in, but has soon as I remove it and it's running on battery the screen backlight goes off.
Tried different battery - no change
Tried different screen - no change
Removed the plastic film from the screen inverter and looked for pwm signal which as about 3.3v when running with the charger plugged in, when I take it off the voltage drops down to 2.232v, so my best guess is that the EC is not providing the correct voltage.... -
Hey I am having Asus Rog strix g15 g513ih hn0865 and it's having display issues while running on igpu. Works fine when I open any game or whatsapp windows application. The issues are :
Black screen, freeze
The weird thing is that when as long as the laptop is running on igpu the problem keeps happening. But as soon as I open any game or whatsapp windows application, the laptop works completely fine.
When the screen freeze or black screen I used to move the display lid up and down and it usually works like that.
So can anyone tell me what would be the possible cause?... -
Hello all,
I'm trying to repair this A2251 macbook pro. Board is 820-01949. The original issue was liquid damage which all cleaned up well and the board was not heavily damaged. Unfortunately after liquid damage cleaning the computer is running extremely slow and the fan is running at full speed. Even the cursor is lagging. Because of this I can't use the built in hardware diagnostic to give me a clue as to what is happening. Does anyone know if Apple Service Diagnostic software is available for this model? Any other clues which could help me out? Seems to me there is an issue with...
