Yes, you are. Pay phones started dying, when cell phones became
popular. They started to disappear, as they no longer took in enough
money to pay for the equipment, the line and the labor to service them.
They finally reached the point where the equipment was worn out, and too
expense to maintain. Payphone companies started to disappear, in the mid
'90s. I hauled off trailer loads of aluminum phone booths from one
company when they downsized to a smaller building. A year later, they
were bankrupt. That was in 1995.
 
As far as cell phone towers, a lot of the cost is in legal fees and
local governments charging out the ass for permits. So it becomes greed,
over safety.

Not so much legal fees. The local cellular operators tend to hire
real estate brokers and such to deal with the local governments.
They're less expensive than lawyers and are more knowledgeable about
local alternative sites, site rental fees, and property costs.
Intentional delays that bordered on extortion became such a problem
that the FCC was forced to require a time limit for acting on proposed
sites new site and modifications.
<http://www.commlawblog.com/2012/01/articles/cellular/fcc-shot-clock-presumptions-for-wireless-tower-permitting-upheld/>
<https://apps.fcc.gov/edocs_public/attachmatch/FCC-09-99A1.pdf>
 
It's not just municipal governments that slow things down. Local
citizens groups that fear the proliferation of RF belching towers also
create delays. For example, this is our local citizens groups:
<https://www.facebook.com/StopBoulderCreekCellTower/>
The Boulder Creek site was never built, but no because of the efforts
of this group. It was due to the county demanding specific basic
documents from the Verizon representative, which were not produced.
 
I has several discussions with the Verizon people about this site and
others that were planned locally, which taught me a few things. For
example, at the time, Verizon had about 1500 new sites in various
stages of planning in Northern California. Most of these sites are
not for new coverage, but are to increase bandwidth and capacity in
areas that already have service. New sites require some minimum
prospective user density to be considered worthwhile, which is a
problem for areas with transient usage. For example, a rather large
lake in the area has nearly zero cellular coverage, despite a large
influx of cell phone users during the summer. Because the area is
essentially empty during the remaining 9 months of the year, it's
probably not going to be profitable investment.
 
Verizon also takes the path of least resistance. If there's any
impediments caused by government or citizen groups and can't seem to
be resolved, Verizon just moves on to another more hospitable area.
The previously mentioned lake owners/operators offered to pay Verizon
for installing a site to compensate for the limited revenue. I don't
know if that worked.
 
Another expensive problem is camouflaged towers, which roughly doubles
the cost of the tower. Yet another is the time involved in crafting
local tower ordinances, no two of which are identical. I was involved
in the passage of the Santa Cruz CA county tower ordinance, which in
my never humble opinion was a giant mess. You really don't want to
know what is involved in making sausage and tower ordinances.
Incidentally, we were saved by the local coastal commission. They
took our best efforts, cleaned it up dramatically, and actually
produced a readable and workable ordinance. Other cities and counties
often use the time needed to create such ordinance as a way of
delaying the introduction of new towers.
 
If you want to slosh through the politics, reading back issues of AGL
(Above Ground Level) magazine should be instructive:

I can go on forever on tower politics, but I'm already late for a
lunch time meeting.

I have a couple tablets. My favorite is a 10" Irulu with an octacore

the other is lost or damaged.

Depends on which country you are. In mine, there was a mandate by which
each village must have at least one payphone, specially on small
villages that do not have a phone per house. That is, if the company can
not set a phone at each house that wants one, they must at least install
one payphone (or more, depending on the population).
 
I don't know if that mandate is still valid.
 
As for mobile, I think there is another mandate that the dominant
provider must provide service on every village. But I'm unsure.

Riding down the interstate today and saw a cell tower made to look like
a tree. It seemed to be about 100 feet or more tall. The top 1/3 or so
had some fake tree things on it to look like a pine tree. Real funny
looking as it was about 50 feet or more taller than any trees around it.
 
It would have been less noticable if it had just the cell antennas on it
instead of the fake tree top.

This is what AT&T (Cingular) installed when they were first forced to
disguise a cell tower or monopole and had no clue what they were doing
but had to build it in a hurry:
<http://www.LearnByDestroying.com/jeffl/crud/AmestiAT&T.jpg>
I'll spare you the jokes about standing lumber trees.
 
People drove for considerable distances to see this abomination when
it was first installed about 20(?) years ago. Incidentally, it's 90ft
high. There was some official debate over the distinction between a
genuine disguise monopine and an attractive nuisance. This created an
awkward situation for AT&T, where modifying or rebuilding the tower
might be construed as agreeing with their critics. So, it was left
unchanged for a few years until the bad jokes died down. A water tank
now sits on the location and a new cell site was built somewhere
close, but further away from the nearby residential areas.

I worked in CATV, Broadcast and Two way radios. The City of
Middletown Ohio's first tower ordinance banned ALL towers, and outdoor
antennas. No exemption for the local AM radio station, CATV headend, or
even the police and fire departments. Their faulty reasoning was if no
one had an antenna, everyone would have to pay for cable, and they would
make more money off the franchise fees which were based on the number of
customers.
 
In the early '80s St. Louis, MO sent our CATV manager an order to
take down their tower and Sat dishes, for the same fool idea. St Lois
was a real mess. They split the city into seven areas, and gave seven
different companies a franchise. They also wanted to make cable
customers pay a large fee to pay for the entire costs to operate the
landfill, and all garbage collection, since watching TV was a 'luxury'.

We do things a little differently on the left coast. The county cell
tower ordinance was inspired by the local drug dealers in about 2000.
We have a rather large local amusement park. Nearby is a residential
slum and ghetto. In the middle of this area, on top of a small hill,
is a two story dilapidated building with a small market downstairs.
It's also the exchange point for most of the local drug deals.
 
Two of the cellular providers decided that if they purged and
disinfected the rooms above the market, it would make a good location
for cell sites. They then applied to the city (not county). This
information was eventually passed to the various drug dealers, who
somehow (correctly) deduced that a cell site located in the middle of
their stomping grounds could be used to accurately track their
movements around the area. So, they organized a protest movement,
which turned the first public hearing into a circus.
 
At this point, someone in city government decided that such things as
tower ordinances was really the job of the county. Characteristically
interested in more powers, the country agreed and decided to write the
tower ordinance. A temporary summer intern was hired by the planning
department to research and cut-n-paste an ordinance together out of
pieces he found on the internet from multiple sources. At the end of
summer he returned to his studies, leaving the county with an
inconsistent and incoherent mess.
 
The only problem was that they didn't know that it was a mess until
after the squabbling began. Every possible organization with an
interest in cellular, towers, land use, aesthetics, historical
preservation, electro biological effects of RF, and alien visitations
became involved. The original drug dealers probably attended the
initial planning department hearings, but were lost in the ever
expanding circus atmosphere.
 
Unfortunately, I was volunteered to represent the interests of the
local ham radio operators. Just one problem. I had recently survived
some major surgery and still felt rather lousy. Sitting for hours in
a crowded meeting room and lecturing morons on basic RF concepts did
not seem very appealing.
 
After the first circus meeting, things settled down to business during
the second meeting. Every group cut up its piece of the ordinance for
special attention. Speakers of all types and abilities presented
their case before the planning department board. There were the usual
comedies, such as one lady who after denouncing cell phones as a
health hazard, had her own cell phone ring while she was at the
podium. Several speakers presented seriously erroneous technical
information about RF. However, the real problem came from one of the
planning department members, who decided to add cell site density and
exposure limitations to the ordinance. Since nobody was interested, I
decided that it was up to me to deal with the problem.
 
When my turn at the podium came, I presented the board with a
simplified explanation about the relationship between transmit power,
data bandwidth, and range. Any two can be traded for the third. If
cellular radio was going to progress, it would need to increase the
data bandwidth. Power was not going up because the batteries in the
handsets would die too quickly. The obvious answer was more cell
sites and denser concentrations of cell sites. Otherwise, the county
was going to be locked into the technical backwaters of 2000. (It was
also illegal for the county to pass such a technical requirement as
that is the domain of the FCC, but I let county council tell them
that). The density and exposure clauses were quietly dropped.
 
I was sitting next to someone who obviously was an attorney. We
talked a little and I discovered he was there to represent AT&T. When
I asked why he said nothing during the hearings, he answered that the
important points would be settled after the ordinance is passed
through the usual exemptions and amendments. He was right.
 
Several meetings later, an ordinance was hammered out that was
sufficient to present to the board of supervisors. They did not want
yet another public circus, so they rubber stamped it on the consent
agenda. Nobody complained.
 
The next step was to pass it to the Coastal Commission, who's approval
was required because many of the cell sites were within the coastal
zone. What we got back was something that resembled bloodshed. There
were so many red marks, corrections, changes, and re-writes on the
various pages, that I barely recognized the ordinance. The Coastal
Commission had passed it on to what I believe was someone with
considerable experience in writing ordinances, who cleaned it up. I
was impressed. The planning board and board of supervisors were less
impressed, but accepted it anyway.
 
<http://www.codepublishing.com/CA/SantaCruzCounty/html/SantaCruzCounty13/SantaCruzCounty1310.html>
13.10.660 thru 13.10.668.
 
In the last 17 years, the ordinance has roughly doubled in size.
Exemptions and exceptions are added regularly to deal with
non-compliant technology and organizations. Life blunders on.
 
If adding a cell site in your neighborhood requires a tower ordinance,
you have my sympathies.

Back in the early to mid '90s, the standard albeit incorrect
answer for "no cell phone use on airplanes" was that they would
interfere with the operation of the airplane.
 
My question was, if that was true, why wasn't Mount Wilson a
smoking crater for the amount of RF it poured out under the
flight path.

First of all, they didn't say cell phones *would* interfere. They
said they *Could* interfere. The transmitters on Mt Wilson are
maintained by professionals. If one of those transmitters would
suddenly start transmitting on an ATC or navaid frequency, they would
figure it out and fix it quickly. Compare that to a few hundred
people on an airliner each with their own little transmitter. If one
of those devices malfunctions and is spewing harmonics, there is no
quick way to find and resolve it. So, asking everyone to turn off
their transmitters reduces the chances of an interference problem. Of
course, some will forget and others refuse, but having 2 or 3 small
transmitters on a plane rather than hundreds reduces the chances of an
issue. You said "if that was true". Not only *was* it true back in
the mid 90's. It *is* still true today. And, why do you want your
phone wasting battery searching for usable cell sites during a long
flight, anyway?

Just off the interstate in South Carolina where everyone can see it is a

When it was in its orange primer it looked like a giant butt sticking

Cell phones in airplanes don't work very well because the phone can
see perhaps hundreds of cell sites simultaneously from the air causing
handoff problems:

Patience. Your crater might arrive eventually. An LAX ATC tried by
aiming a Boeing 777 Dreamliner at Mt Wilson in order to produce the
required crater:

Since that failed, it might be possible to attempt to burn it down
again, once the trees and brush grow back:
<http://www.universetoday.com/wp-content/uploads/2009/09/Mt.-Wilson-with-labeled-names-of-scopes.jpg>
 
The bottom line is that cell phone interference is unlikely, but still
too much of a potential problem to risk a disaster. Better safe than
sorry. Besides, I don't want to fly in an airplane full of people
trying to yell over the engine noise into their cell phones.

So here's the final solution. The new power adapter powered the laptop
consistently, however it only charged the battery once. Then it refused
to charge again.
 
Updating the BIOS to the latest version fixed that problem as well, so
now everything is working fine. I had to use the "hack" method though,
as of course I didn't realize there was a problem remaining until the
battery had fully discharged, and the Windows update tool requires the
battery to be above 10% to operate, as "ohger1" mentioned.
 
For future reference, you get Dell Diagnostic Deployment Package (DDDP)
here:
 
<https://www.dell.com/support/article/us/en/19/SLN143196/how-to-create-a-bootable-usb-flash-drive-using-dell-diagnostic-deployment-package--dddp-?lang=EN>
 
and also the latest BIOS update executable. Follow the instructions to
make a bootable USB flash drive with the proper DOS startup files.
 
Hit F12 on startup and switch the boot mode from "UEFI" to "Legacy."
Restart and select the USB flash drive to boot from and a DOS prompt
like "Diag C:\>" should come up.
 
The BIOS update file will show up with the usual "~1" at the end to
represent an extended filename. On mine it was "INSPIR~1.EXE". Type
"INSPIR~1.EXE /forceit" (hidden option) to force a BIOS update while on
AC power with a dead battery.
 
After the BIOS is flashed shut down the computer, remove the battery and
hold down the power switch for about 20 seconds. Reboot, switch the boot
mode back to "UEFI" and boot into Windows and the charging light should
come on indicating the battery is charging properly. Yay!
