Document findings, actions, and outcomes.
Establish a theory of probable cause (question the obvious).
Document findings, actions, and outcomes.
The steps are as follows:
Identify the problem.
Establish a theory of probable cause (question the obvious).
Test the theory to determine cause.
Establish a plan of action to resolve the problem and implement the solution.
Verify full system functionality and, if applicable, implement preventive measures.
Document findings, actions, and outcomes.

A bad NIC driver would cause the NIC not to work but would not cause a system lockup
What are proprietary screen crashes called in Windows?
BSOD
Bomb screen
PSOID

What is the light in the device that powers the LCD screen?
Backlight
Inverter
Charger
Backlight
The backlight is the light in the device that powers the LCD screen. It can go bad over time and need to be replaced, and it can also be held captive by the inverter. The inverter takes the DC power the laptop is providing and boosts it up to AC to run the backlight. If the inverter goes bad, you can replace it on most models (it’s cheaper than the backlight)

Type I
TouchFLO
Container-based
TouchFLO
