Hi @oubayd
A 5:3 error code indicates that the embedded controller cannot reach the BIOS within the established time limit.
Did you have the battery disconnected from the motherboard when you cleaned the fans and refreshed the thermal paste on the CPU/GPU?
The BIOS may have become corrupted. Try a power refresh and check if that resolves the problem.
Here’s the procedure:
a). Disconnect the charger from the laptop if connected.
b). Disconnect the main battery from the motherboard.
Here’s the maintenance and service guide, taken from this support webpage for the laptop. Go to p.45 to view the procedure to remove the battery.
c). Press and hold the laptop's Power button for a full 30 seconds and then release it.
d). Reverse the above from Step b). to re-assemble the laptop.
e.) When the laptop is completely re-assembled, connect the charger and try to turn on the laptop.
If it starts OK there may be a message about the date and time being incorrect. This is normal as the BIOS has been completely reset back to its default settings. Once the date and time have been adjusted the message won’t appear the next time that the laptop is started.
If you had previously changed any user defined settings in BIOS to suit whatever specific hardware configuration that you had for the laptop, then these will have to be set again.
