Disassembly DELL Latitude 7490 3541TQ2

Hello, very good video. I have the same notebook giving me blue screens and I couldn't find the damaged component, because the error codes are various. I noticed that the fingerprint reader gets hot and doesn't work, could that be the problem? Can it be disconnected?

Hello! Thanks for the kind words!!! Have you tried reinstalling the system? The cause of blue screens of death can be a software glitch, overheating or damage to the CPU / GPU, a failed RAM module, or an HDD / SSD storage medium. The fingerprint reader must have a separate cable to the motherboard, unplug it.

@@victorkrynytsky I have tried everything but could not solve the problem. I can only use the laptop when I enable SpeedStep or TurboBoost, one at a time, and disable processor C states.

Hello! Based on your words, it seems that the central processor is damaged. Or the CPU power is damaged. All of these functions control the processor's power.
