Hi. HP Probook 450 G1 (Rampage_MB 12241-1 48.4YW05.011) does not turn off. I replaced the dead cmos battery, the bios settings are remembered, but every time I turn off the operating system, the laptop turns off and restarts after a while. The system will not wake up when there is no battery, and after turning it off I disconnect it from the 19V power supply. After connecting the power supply, I can turn it on by pressing the power button. After booting up, I unplugged the power button but the problem still persists. It's the same with sleep - after closing the lid, the laptop goes into sleep mode, reduces power consumption to a minimum (~ 10mA), and then turns on itself. I updated the bios but it didn't help. Is the 3.37V voltage on the power button correct? Is there anything else I can check? The motherboard looks good, I don't see any mechanical damage or traces of liquid spills.
