Default Advice on purchasing Inspiron 1525 laptop

doesn't believe specs exist.


Which number claims protection from each type of surge? Christopher
cannot say. He does not know what numbers define surge protection.
So Christopher Muto posted a link to a subjective sales brochure – and
posted no numbers.

No protection numbers are provided because the APC and Tripplite
circuits are the same circuit in that generic power strip.
Christopher did not know that. Christopher recommended without
knowing all three are electrically same. Christopher recommended only
protectors with higher profit margins.

Bud - who promotes power strip protectors - has cut and pasted his
usual diatribe. Good. Page 42 Figure 8 demonstrates what the APC and
Tripplite protectors actually do. Without earth ground, the spike is
earthed 8000 volts destructively through an adjacent TV. Page 42
Figure 8 of Bud's IEEE guide shows why telcos don't waste money on APC
and Tripplite products. Telcos use protectors that actually provide
protection. Telcos use the 'whole house' protector earthed where a
spike cannot enter the building.

Bud's second citation is even more damning. Bud's NIST citation
says why APC and Tripplite protectors do not provide those spec
numbers:
You cannot really suppress a surge altogether, nor
"arrest" it. What these protective devices do is
neither suppress nor arrest a surge, but simply
divert it to ground, where it can do no harm.


Divert (shunt, connect) a spike to earth. How does APC or Tripplite
without earthing provide protection? Neither do. Bud's NIST citation
(page 19 of 24) is even blunter:
A very important point to keep in mind is that your
surge protector will work by diverting the surges to
ground. The best surge protection in the world can
be useless if grounding is not done properly.


Spike energy must be dissipated somewhere. Will that silly little
APC or Tripplite protector stop or absorb what three kilometers of sky
could not? Bud says yes. But even Bud's citations say spike energy
must be dissipated in earth. No wonder telcos waste no money on APC
or Tripplite protectors. Where is energy harmlessly dissipated? In
earth. Effective (and much less expensive) protectors have a short
(ie less than 3 meter) connection to earth.

No wonder Christopher Muto still will not post those protection
numbers. Those numbers do not exist. He does not know what the sales
brochure says. So Christopher must argue rather than post numbers.

Protecting a laptop and everything else inside a building means
earthing before a spike can enter that building. A protector is only
as effective as that 'less than 3 meter' connection to earth. No
earth ground means nothing will stop or dissipate spike energy. No
earth ground is why telcos don't waste money on what Christopher Muto
has recommended.
