This is my first try to fix a laptop.
- the laptop show red led immediately after attaching power source (bettery charging circuit)
- Power button seem ok, when pressed a blue light shown on left of the red one after 2 seconds (more or less)
- Nothing visibly damaged (no evident blown components )
- I checked some caps and around the power section, everything seem
fine... nothing seem short, power rails seem ok (19V Or 3.3v found on all tested components) - Fan start after around 20 seconds after starting the laptop
- Cpu became a little bit hot so seem that correctly receive power
how can I diagnose this problem more deeply?
Thank you for any suggestion and support.
