I had to replace the FAN as original was broken.
I ordered the same FAN from Chinese site and replaced it.
This new FAN works cool and quiet as expected but the laptop seems not to be able to detect the FAN speed at startup.
When I power it on the FAN speeds up and lights go on for 1-2 seconds and then off.
Then again and again and eventually it starts just fine on 1-st or 3-rd or N-th attempts. Once started it's rock solid.
I looked in BIOS for option to ignore FAN speed detection like in other computers but there's not such.
I updated to the latest BIOS and it's still the same (https://download.lenovo.com/consumer/mobiles/62cn44ww_64.exe).
Can you please help?
