If that data is saved, then only serious threats are from hardware damage from a transient or the more common threat - failure from a manufacturing defect.

Informed consumers waste no money on profit center protectors with near zero protection (joule) numbers. Informed consumers spend tens of times less money to properly earth a 'whole house' protector. And focus most attention on the critical item - connections to and quality of single point earth ground.

Since potentially destructive surges are 20,000 amps, then a minimal 'whole house' protector is 50,000 amps. Because effective protectors (that cost tens of times less money) do not fail over many decades after many direct lightning strikes.

That is protector life expectancy over many surges. Protector effectiveness during each surge is defined by the low impedance (ie less than 10 foot) connection to earth ground and the quality of that earthing electrode.

That (and not myths hyped by irrelevant PE papers) is how protection has been done even in every facility that cannot have damage even 100 years ago. Informed professionals (demonstrates by three examples) always recommend that and not advertising myths.

If a laptop needs protection, then so does everything else inside the building. Only a 'whole house' solution, from other companies so well know for integrity, provides best protection. 99.5% protection (nothing is perfect because humans make mistakes). For decades, to avert fires created by protector, so that nobody knows a surge existed, and for tens of times less money.

Reasons why only posted by those who were doing this stuff probably long before he was even born.

The effective solution always answers this question. Where do hundreds of thousands of joules harmlessly dissipate. A protector is only as effective as its earth ground.
