Hello Everyone,
I have this board that has an autostart as soon as i connect the charger (no POST) and restarts after 20 seconds. cannot be turned off.
I'm suspecting main EC firmware problem (IT8227E-192)
Since this board has only EC_KSI6 and EC_KSI7 pin on keyboard connector to the EC this cannot be programmed trought it.
I would like to know if anyone can give me instruction how to program the EC.
In the Vertyanov tutorial instructions I have seen that alternative is using 8pin direct cable soldered to board.
Anyone knows hows if that is working...

Bricked HP Probook 450 G7 Bios questions
Hp Probook 450 G7 s# SCD0348W35 had a locked BIOS. Bought BIOS and EC chips off Ebay that were supposed to match this machine - the 450 G7. Flashed in the BIOS on chip i bought using a CH341. BIOS unlocked next boot. Some error to contact HP. Entered BIOS and reset to system defaults and rebooted. Machine worked fine but every cold boot the contact HP message popped and everything else worked as fine. Assumed the error was from EC chip not matching BIOS that i just flashed in. So i flashed in the EC that was supposed to match from the EBay chip i bought and instant brick.

GRT60-145410 brick PSU, how much of a fire hazard is this thing exactly?
I bought an Alpicool C20 fridge, which is a 60W compressor fridge that runs on 12V or 24V, which can come from either an AC/DC adapter from mains (240V here in UK) or a car battery. The fridge itself is really good quality, so I was surprised to find the power supply (DC14.5V, 4.1A) pretty questionable. Despite being 240V/1.5A the plug was fitted with a 13A fuse - concerning, but not all that uncommon for imported chinese electronics here. But when I felt how light the brick was I immediately said hell no and transferred the proprietary connector to a MeanWell GS90A12-P1M brick (this supply is...
