Hi all!
A friend asked me to repair his biomass (pellet) heater. This heater has a pellet feeder powered by a relay that's not switching anymore
I measured the voltage at the relay coil socket while entering the individual tests procedures and it has 6-7v while the relay is NOT on the socket, and drops to 0v when the relay is plugged in the socket, like the source is providing nearly 0 mA.

Hello!
Today i received a Legion 5 pro with motherboard NM-D562 that suffered water damage, no power at all, no led, no fans, nothing.
I measure 20v on PQ5401 at pins 5, 6, 7 and 8 but 0v at 1, 2, 3 and 4.
Is this normal?
Thanks in advance!

I bought an universal programmer but I cannot find the software.It comes out in different names (Dataman 48uxp ,Labtool 48uxp etc).Maybe someone can help me find it .
The device looks like this
Thanks in advance, -
I have a Dell gaming laptop here that initially showed a blink code for a power rail failure (3 red, 5 blue). After having a poke around with the board unplugged for a while, and testing again, the blink code is gone. The board responds to the power button being pushed with the PCH powering up when looked at with a thermal camera, but there are no lights or fans. Can someone help me refresh this BIOS so I can rule that out?
