ask for help. I am handling a Sony Vaio laptop mboard code FI2 core i5 hashwel with thoucscreen. the problem is the laptop turns off every 30 minutes (from pressing the button) again and again. standby or working together die on the 30th minute.
I have tried
- Flash bios with clean me
- replaced capacitors 3/5VA, vcc-coore and vga-core
-resoldering KBC and ICs
-replaced Thermall sensor TMP709 for Processor and HDD
-tried with less keyboard, power switch bord, and card
-reinstall os
-tried on win pe and stay on bios stay dead 30 minutes
while running windows i have tried checking the Acin and all_pwrgd pin on kbc has 3.3V and 62.7mV on Peak to peak (normal)
and not overheating
